Astronomy & Space news
![]() | Steep slopes on Mars reveal structure of buried iceResearchers using NASA's Mars Reconnaissance Orbiter (MRO) have found eight sites where thick deposits of ice beneath Mars' surface are exposed in faces of eroding slopes. |
![]() | No planets needed: NASA study shows disk patterns can self-generateWhen exoplanet scientists first spotted patterns in disks of dust and gas around young stars, they thought newly formed planets might be the cause. But a recent NASA study cautions that there may be another explanation—one that doesn't involve planets at all. |
![]() | GBT detection unlocks exploration of 'aromatic' interstellar chemistryAstronomers had a mystery on their hands. No matter where they looked, from inside the Milky Way to distant galaxies, they observed a puzzling glow of infrared light. This faint cosmic light, which presents itself as a series of spikes in the infrared spectrum, had no easily identifiable source. It seemed unrelated to any recognizable cosmic feature, like giant interstellar clouds, star-forming regions, or supernova remnants. It was ubiquitous and a bit baffling. |
![]() | Champagne box-sized satellite to probe distant planetFrance is set to launch a champagne box-sized mini satellite into Earth orbit on Friday to study a mysterious, juvenile planet system in our Milky Way galaxy, mission controllers said. |
![]() | New SOFIA observations help unravel mysteries of the birth of colossal sunsAstronomers are observing star-forming regions in our galaxy with NASA's flying telescope, the Stratospheric Observatory for Infrared Astronomy, SOFIA, to understand the processes and environments required to create the largest known stars, which tip the scales at ten times the mass of our own Sun or more. |
![]() | NASA team first to demonstrate X-ray navigation in spaceIn a technology first, a team of NASA engineers has demonstrated fully autonomous X-ray navigation in space—a capability that could revolutionize NASA's ability in the future to pilot robotic spacecraft to the far reaches of the solar system and beyond. |
![]() | Hubble finds substellar objects in the Orion NebulaUsing NASA's Hubble Space Telescope to peer deep into the vast stellar nursery called the Orion Nebula, astronomers searched for small, faint bodies. What they found was the largest population yet of brown dwarfs—objects that are more massive than planets but do not shine like stars. Researchers identified 17 brown dwarf companions to red dwarf stars, one brown dwarf pair, and one brown dwarf with a planetary companion. They also found three giant planets, including a binary system where two planets orbit each other in the absence of a parent star. This survey could only be done with Hubble's exceptional resolution and infrared sensitivity. |
![]() | Possible lava tube skylights discovered near the North Pole of the MoonThe SETI Institute and the Mars Institute announced today the discovery of small pits in a large crater near the North Pole of the Moon, which may be entrances to an underground network of lava tubes. The pits were identified through analysis of imaging data from NASA's Lunar Reconnaissance Orbiter (LRO). If water ice is present, these potential lava tube entrances or "skylights" might allow future explorers easier access to subsurface ice, and therefore water, than if they had to excavate the gritty ice-rich "regolith" (surface rubble) at the actual lunar poles. |
![]() | Citizen scientists discover five-planet systemIn its search for exoplanets—planets outside of our solar system—NASA's Kepler telescope trails behind Earth, measuring the brightness of stars that may potentially host planets. The instrument identifies potential planets around other stars by looking for dips in the brightness of the stars that occur when planets cross in front of, or transit, them. Typically, computer programs flag the stars with these brightness dips, then astronomers look at each one and decide whether or not they truly could host a planet candidate. |
![]() | Magnetic coil springs accelerate particles on the SunIn April and July 2014, the Sun emitted three jets of energetic particles into space, that were quite exceptional: the particle flows contained such high amounts of iron and helium-3, a rare variety of helium, as have been observed only few times before. Since these extraordinary events occurred on the backside of our star, they were not discovered immediately. A group of researchers headed by the Max Planck Institute for Solar System Research (MPS) and the Institute for Astrophysics of the University of Göttingen (Germany) present a comprehensive analysis now in the Astrophysical Journal. It is based on data from the twin space probes STEREO A and STEREO B, which – at that time still both operating – were in a favorable observation position behind the Sun at the crucial time. For the first time, the study shows a correlation between helium-3 and iron-rich particle flows and helical eruptions of ultraviolet radiation in the Sun's atmosphere. These could provide the necessary energy to accelerate the particles into space. |
![]() | Researchers catch supermassive black hole burping—twiceA team led by CU Boulder researchers has caught a supermassive black hole in a distant galaxy snacking on gas and then "burping"—not once, but twice. |
![]() | NASA space telescopes provide a 3-D journey through the Orion NebulaAstronomers and visualization specialists from NASA's Universe of Learning program have combined visible and infrared vision of the Hubble and Spitzer space telescopes to create an unprecedented, three-dimensional, fly-through view of the picturesque Orion Nebula, a nearby star-forming region. |
![]() | Hubble probes the archeology of our Milky Way's ancient hubFor many years, astronomers had a simple view of our Milky Way's central hub, or bulge, as a quiescent place composed of old stars, the earliest homesteaders of our galaxy. |
![]() | Hubble and Spitzer team up to find magnified and stretched out image of distant galaxyAn intensive survey deep into the universe by NASA's Hubble and Spitzer space telescopes has yielded the proverbial needle-in-a-haystack: the farthest galaxy yet seen in an image that has been stretched and amplified by a phenomenon called gravitational lensing. |
![]() | Astronomers to build space telescope to explore nearby starsIn 2021, a spacecraft the size of a Cheerios box will carry a small telescope into Earth orbit on an unusual mission. Its task is to monitor the flares and sunspots of small stars to assess how habitable the space environment is for planets orbiting them. |

![]() | The night sky magic of the AtacamaThere's nothing an astronomer – whether professional or amateur – loves more than a clear dark night sky away from the city lights. Outside the glare and glow and cloud cover that most of us experience every day, the night sky comes alive with a life of its own. |
![]() | The surprising scale of China's space programIt's no secret that China's growth in the past few decades has been reflected in space. In addition to the country's growing economic power and international influence, it has also made some very impressive strides in terms of its space program. This includes the development of the Long March rocket family, the deployment of their first space station, and the Chinese Lunar Exploration Program (CLEP) – aka. the Chang'e program. |

![]() | Surprise: A virus-like protein is important for cognition and memoryA protein involved in cognition and storing long-term memories looks and acts like a protein from viruses. The protein, called Arc, has properties similar to those that viruses use for infecting host cells, and originated from a chance evolutionary event that occurred hundreds of millions of years ago. |
![]() | Rare melanoma type highly responsive to immunotherapyDesmoplastic melanoma is a rare subtype of melanoma that is commonly found on sun-exposed areas, such as the head and neck, and usually seen in older patients. Treatment is difficult because these tumors are often resistant to chemotherapy and lack actionable mutations commonly found in other types of melanoma that are targeted by specific drugs. However, Moffitt Cancer Center researchers report in the Jan. 10 issue of Nature that patients with desmoplastic melanoma are more responsive to immune-activating anti-PD-1/PD-L1 therapies than previously assumed. |
![]() | With these special bacteria, a broccoli a day can keep the cancer doctor awayColorectal cancer is one of the most common cancers in the developed world. Although the five-year survival rates for earlier stages of this cancer are relatively high, at later stages, survival drops and the risk of cancer recurrence rises considerably. |
![]() | Babies stir up clouds of bio-gunk when they crawlWhen babies crawl, their movement across floors, especially carpeted surfaces, kicks up high levels of dirt, skin cells, bacteria, pollen, and fungal spores, a new study has found. The infants inhale a dose of bio bits in their lungs that is four times (per kilogram of body mass) what an adult would breathe walking across the same floor. |
![]() | Scientists use gene expression to understand how astrocytes change with agePotentially explaining why even healthy brains don't function well with age, Salk researchers have discovered that genes that are switched on early in brain development to sever connections between neurons as the brain fine-tunes, are again activated in aging neuronal support cells called astrocytes. The work, which appeared in Cell Reports on January 2, 2018, suggests that astrocytes may be good therapeutic targets to prevent or reverse the effects of normal aging. |
![]() | Re-programming innate immune cells to fight tuberculosisTuberculosis (TB), an infectious disease which attacks the lungs, claims a life every 20 seconds and 1.5 million lives worldwide every year. A cure has eluded scientists for more than a century but, now, a Montreal team of researchers may have discovered a new weapon to combat this global killer. The team is re-programing - or 'training' - immune cells to make them kill TB. These groundbreaking findings are published online today in the journal Cell. |
![]() | Estrogen-mimicking compounds in foods may reduce effectiveness of breast cancer treatmentScientists from The Scripps Research Institute (TSRI) have discovered that two estrogen-mimicking compounds found in many foods appear to potently reverse the effects of palbociclib/letrozole, a popular drug combination for treating breast cancer. |
![]() | By altering bone marrow, training can prepare innate immune system for future challengesWhen you receive a vaccine against a disease like polio or influenza, your immune system gears up to defend against that particular infection. If you wind up getting chickenpox instead, or even a slightly different strain of the flu, you would be out of luck. That's because traditional vaccines enlist the adaptive immune system, the functions of which are carried out largely by hyperspecific T and B cells, each targeted to a particular threat. |
![]() | The brain's GPS has a buddy systemTo be successful as a social animal, you need to know where you stand relative to others. Brain cells that perform precisely this function—locating the 'self' and others in space—have now been identified. In rats, the same brain area that stores the animal's own location also maps the movements of other rats. Sometimes these representations are processed jointly by the same cells, depending on a rat's goals and actions. This discovery, from Japan's RIKEN Brain Science Institute, deepens our understanding of the hippocampus and its role as the brain's positioning system. |
![]() | Research discovers possible link between Crohn's and Parkinson's in Jewish populationMount Sinai Researchers have just discovered that patients in the Ashkenazi Jewish population with Crohn's disease (a chronic inflammatory of the digestive system) are more likely to carry the LRRK2 gene mutation. This gene is the major genetic cause of Parkinson's disease, which is a movement disorder. The study's findings, published in the January 10, 2018 issue of Science Translational Medicine, and featured on the cover, could help doctors better understand Crohn's disease, determine specifically who's at risk, and develop new drugs for treatment and/or prevention by targeting this specific gene. |
![]() | The coming of age of gene therapy: A review of the past and path forwardAfter three decades of hopes tempered by setbacks, gene therapy—the process of treating a disease by modifying a person's DNA—is no longer the future of medicine, but is part of the present-day clinical treatment toolkit. The Jan. 12 issue of the journal Science provides an in-depth and timely review of the key developments that have led to several successful gene therapy treatments for patients with serious medical conditions. |
![]() | Scientists identify immune cells that keep gut fungi under controlImmune cells that process food and bacterial antigens in the intestines control the intestinal population of fungi, according to a new study from Weill Cornell Medicine scientists.

Housework gender differences may affect health in elderly men and womenElderly men across Europe and the US spend less time on housework than elderly women, according to a study published in the open access journal BMC Public Health. Researchers at the Leibniz Institute for Prevention Research and Epidemiology found that elderly women on average spent almost five hours a day doing housework compared to only around three hours a day for elderly men. The study also found that while those who did more housework felt healthier, women who did long hours of housework combined with too much or too little sleep reported poorer health. | |
![]() | Enzyme shown to regulate inflammation and metabolism in fat tissueThe human body has two primary kinds of fat—white fat, which stores excess calories and is associated with obesity, and brown fat, which burns calories in order to produce heat and has garnered interest as a potential means of combating obesity. |

![]() | Why a drug treatment for dementia eludes researchersFinding a cure for neurodegenerative diseases such as Alzheimer's is challenging. They're difficult to diagnose, and drugs struggle to get into the brain as the brain's blood supply is largely separate to the rest of the body. Not surprisingly, several companies have left this territory in recent years. This week, pharmaceutical giant Pfizer announced it will stop research into developing drugs to treat Alzheimer's disease, after costly failed attempts over the past decade. |
![]() | Stroke patients at higher risk for suicide attemptsStrokes can be disabling, leaving survivors to confront many challenges during their recovery. Now, a new Asian study shows survivors are at higher risk for attempting suicide, especially if they are younger, less affluent and have a physically demanding job. |
How the immune system curbs its own mistakesWhen we encounter a pathogen, the immune system is usually able to respond quickly and forcefully to protect us from infection. Some of its preparedness is inherent in the process by which white blood cells called B cells make antibodies, proteins fine-tuned to recognize a specific invader. Within structures called germinal centers, B cells undergo many mutations to diversify—and when a pathogen attacks, those cells making the most potent antibodies are singled out and start multiplying quickly. | |
![]() | What supplements do scientists use, and why?Supplements are a multi-billion dollar industry. But, unlike pharmaceutical companies, manufacturers of these products don't have to prove that their products are effective, only that they are safe – and that's for new supplements only. |

![]() | Six easy ways to encourage children to eat less sugarA new campaign from Public Health England is urging parents to limit snacks for children to two a day, and 100 calories a piece. The aim is to reduce kids' sugar consumption – according to PHE data, children eat on average 10kg of sugar every year, with about half of this coming from sugary drinks and snacks. |
![]() | Study identifies brain circuit controlling social behaviorA new study by researchers at Roche in Basel, Switzerland has identified a key brain region of the neural circuit that controls social behavior. Increasing the activity of this region, called the habenula, led to social problems in rodents, whereas decreasing activity of the region prevented social problems. |
New biomarkers for colorectal cancerFor colorectal cancer (CRC), early detection and classification is important, as not all Stage II patients benefit from chemotherapy. Identifying patients at risk for recurrence during the early course of the disease might help clinicians. However, there are still too few prognostic markers for colorectal cancer known so that too many patients still suffer needlessly from side effects of the chemotherapy without having real benefits. | |

![]() | High-risk plaque on coronary CTA linked to future MACE(HealthDay)—For outpatients with stable chest pain, high-risk plaque found by coronary computed tomographic angiography (CTA) is associated with subsequent major adverse cardiovascular events (MACE), according to a study published online Jan. 10 in JAMA Cardiology. |
![]() | Cervical lesions change fastest in Hispanics, slowest in blacks—for better and worsePhysicians determining treatment options following abnormal Pap smears now have another factor to consider: the patient's race. |
![]() | Removing the immunotherapy blindfoldImmunotherapies are promising in theory, but often not in practice. In fact according to experts, they actually only work 10 percent of the time in the treatment of cancer – at best. Yet, while immunotherapy drugs may only help a minority of patients, those who do respond often do extremely well. As a result, many scientists are working to tap into the treatment's benefits for a wider group of patients. |
![]() | The 'greatest pandemic in history' was 100 years ago – but many of us still get the basic facts wrongThis year marks the 100th anniversary of the great influenza pandemic of 1918. Between 50 and 100 million people are thought to have died, representing as much as 5 percent of the world's population. Half a billion people were infected. |
![]() | When sexual assault victims speak out, their institutions often betray themA 27-year-old medical resident in general surgery is sexually harassed by two men – the chief resident and a staff physician at the hospital. She feels trapped. When one of the men's actions escalates to assault, she struggles to find the strength and courage to report it. |
![]() | New expert guidance on contact precautions for drug-resistant infectionsNew expert guidance released today by the Society for Healthcare Epidemiology of America advises hospitals on determining when they can safely discontinue contact precautions for patients with multi-drug resistant bacteria. The framework, published in Infection Control and Hospital Epidemiology, addresses how long hospital staff should use these safety protocols to reduce the spread of potentially deadly organisms within the hospital, in most cases ranging from one to three negative cultures prior to discontinuation. The guidance also outlines the use of molecular testing that is guiding these care decisions. |
Teenagers gamble away their educationThe odds are stacked against teenagers who regularly gamble. A new study in Springer's Journal of Gambling Studies shows that a 14-year-old who gambles is more likely to struggle at school.

Study suggests many gay and bisexual men are skeptical, but attitudes are on the riseDr. Jonathon Rendina, an Assistant Professor at Hunter College and Director of Quantitative Methods at Hunter's Center for HIV Educational Studies & Training, and Dr. Jeffrey Parsons, Distinguished Professor at Hunter and Director of CHEST, have published a new paper in the Journal of the International AIDS Society focused on gay and bisexual men's perceptions of the HIV treatment-as-prevention message, "Undetectable = Untransmittable." Numerous well-controlled trials have recently demonstrated that there is effectively no risk of HIV transmission during sex with a partner who has a sustained, undetectable viral load. This notion, that HIV treatment can lead to HIV prevention, has been captured with the #UequalsU slogan popularized by Bruce Richman and the Prevention Access Campaign, of which he is Executive Director, and has gained growing popularity and endorsements, including the U.S. Centers for Disease Control and Prevention (CDC). The Hunter CHEST study sought to examine how accurate gay and bisexual men perceive this message to be by surveying more than 12,000 men across the United States in the summer of 2017. | |

![]() | Malaria parasite packs genetic material for trip from mosquitoes to humansThe parasite that causes malaria has not one, but two, specialized proteins that protect its messenger RNAs—genetic material that encodes for proteins—until the parasite takes up residence in a new mosquito or a human host. A new study by researchers at Penn State describes the two proteins and reveals an additional role that one may play to facilitate RNA-based interactions between the parasite, its mosquito vector, and its human host. The study appears January 10, 2018, in the journal mSphere. |
![]() | Frogs reveal mechanism that determines viability of hybridsWhy are some hybrids viable and others not? It is known that this depends on the father species and the mother species. New research in two related frog species shows the influence of mother and father species: One hybrid is viable, the other hybrid dies in early stages of development. Scientists from Radboud University, together with colleagues from the United States and Japan, published their findings on 10 January in Nature. |

![]() | Spider eat spider: Scientists discover 18 new spider-hunting pelican spiders in MadagascarIn 1854, a curious-looking spider was found preserved in 50 million-year-old amber. With an elongated neck-like structure and long mouthparts that protruded from the "head" like an angled beak, the arachnid bore a striking resemblance to a tiny pelican. A few decades later when living pelican spiders were discovered in Madagascar, arachnologists learned that their behavior is as unusual as their appearance, but because these spiders live in remote parts of the world they remained largely unstudied—until recently. |
![]() | Rising CO2 is causing trouble in freshwaters too, study suggestsAs carbon dioxide (CO2) levels in the atmosphere rise, more CO2 gets absorbed into seawater. As a result, the world's oceans have grown more acidic over time, causing a wide range of well-documented problems for marine animals and ecosystems. Now, researchers reporting in Current Biology on January 11 present some of the first evidence that similar things are happening in freshwaters too. |
![]() | Researchers map druggable genomic targets in evolving malaria parasiteResearchers at University of California San Diego School of Medicine, with colleagues across the country and around the world, have used whole genome analyses and chemogenetics to identify new drug targets and resistance genes in 262 parasite cell lines of Plasmodium falciparum—protozoan pathogens that cause malaria—that are resistant to 37 diverse antimalarial compounds. |
![]() | Solving Darwin's 'abominable mystery': How flowering plants conquered the worldScientists have found an explanation for how flowering plants became dominant so rapidly in ecosystems across the world—a problem that Charles Darwin called an 'abominable mystery'. In a study publishing on January 11 in the open access journal PLOS Biology, Kevin Simonin and Adam Roddy, from San Francisco State University and Yale University respectively, found that flowering plants have small cells relative to other major plant groups and that this small cell size is made possible by a greatly reduced genome size. |
![]() | Scientists make cells that enable the sense of touchResearchers at the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA have, for the first time, coaxed human stem cells to become sensory interneurons—the cells that give us our sense of touch. The new protocol could be a step toward stem cell-based therapies to restore sensation in paralyzed people who have lost feeling in parts of their body. |
![]() | All in the family: Focused genomic comparisonsFound in microbial communities around the world, Aspergillus fungi are pathogens, decomposers, and important sources of biotechnologically-important enzymes. Each Aspergillus species is known to contain more than 250 carbohydrate active enzymes (CAzymes), which break down plant cell walls and are of interest to Department of Energy (DOE) researchers working on the industrial production of sustainable alternative fuels using candidate bioenergy feedstock crops. Additionally, each fungal species is thought to contain more than 40 secondary metabolites, small molecules with the potential to act as biofuel and chemical intermediates. |
![]() | The origin of flower-making genesFlowering plants have evolved from plants without flowers. It is known that the function of several genes, called MADS-box genes, creates shapes peculiar to flowers such as stamens, pistils and petals. Plants that do not produce flowers, such as mosses, ferns and green algae, are also known to have the MADS-box genes. However, it was not well understood how the MADS-box genes work in plants without flowers until now. In order to understand the mechanism of flower evolution, it is necessary to understand how the MADS-box genes work in plants without flowers. |
![]() | Why did the passenger pigeon die out?Why do species die out? This is the overarching question being asked by many leading researchers.

![]() | Everything you never wanted to know about bed bugs, and moreIf some insects could save the world, others do their best to seriously complicate life on earth. Among them the prize perhaps goes to the bed bug, which after decades of absence has returned to our homes, hotels and public facilities to seriously disturb us. |
![]() | Turning power over to states won't improve protection for endangered speciesSince the Endangered Species Act became law in 1973, the U.S. government has played a critical role in protecting endangered and threatened species. But while the law is overwhelmingly popular with the American public, critics in Congress are proposing to significantly reduce federal authority to manage endangered species and delegate much of this role to state governments. |
![]() | As climate warms, more bird nests are destroyed in Finnish farmlandsA new study shows that birds have shifted the time of their breeding much more quickly than Finnish farmers are anticipating their sowing times. This means that more birds are laying their eggs on fields that are still to be sown, a mismatch in timing that is most likely fatal for the bird nests. |
![]() | Rising temperatures turning major sea turtle population femaleScientists have used a new research approach to show that warming temperatures are turning one of the world's largest sea turtle colonies almost entirely female, running the risk that the colony cannot sustain itself in coming decades, newly published research concludes. |
![]() | Scientists identify the link between light and chloroplast developmentIt has long been assumed that light activates chloroplastic gene expression via so-called thiol-mediated redox regulation. However, the mechanism giving rise to this regulation has remained elusive until now. Åsa Strand and her group at the Umeå Plant Science Centre have now identified the components involved in this redox regulatory mechanism. Their results are published in the journal Nature Communications. |

Maintaining tiger connectivity and minimising extinction into the next centuryTigers have lost 95% of their historical range, and what remains is highly fragmented. According to this study, high traffic roads and densely populated urban areas are a severe impediment to tiger movement between fragments. Unplanned development in the future will result in loss of connectivity and an increased possibility of extinction for several tiger populations. To ensure future persistence, tiger populations need to be managed as a network of protected areas connected by corridors. | |
