Hubble provides interstellar road map for Voyagers' galactic trek

NASA's two Voyager spacecraft are hurtling through unexplored territory on their road trip beyond our solar system. Along the way, they are measuring the interstellar medium, the mysterious environment between stars. NASA's Hubble Space Telescope is providing the road map - by measuring the material along the probes' future trajectories. Even after the Voyagers run out of electrical power and are unable to send back new data, which may happen in about a decade, astronomers can use Hubble observations to characterize the environment of through which these silent ambassadors will glide.

Can garnet planets be habitable?

What makes a rocky planet Earth-like? Astronomers and geoscientists have joined forces using data from the Sloan Digital Sky Survey (SDSS) to study the mix of elements in exoplanet host stars, and to consider what this reveals about their planets.

The elements of life mapped across the Milky Way by SDSS/APOGEE

To say "we are stardust" may be a cliche, but it's an undeniable fact that most of the essential elements of life are made in stars.

Spacewalking astronauts upgrade station with new batteries

Spacewalking astronauts hooked up fancy new batteries Friday on the International Space Station's sprawling power grid.

The case of the 'missing link' neutron star

Like anthropologists piecing together the human family tree, astronomers have found that a misfit "skeleton" of a star may link two different kinds of stellar remains. The mysterious object, called PSR J1119-6127, has been caught behaving like two distinct objects—a radio pulsar and a magnetar—and could be important to understanding their evolution.

NASA study finds solar storms could spark soils at moon's poles

Powerful solar storms can charge up the soil in frigid, permanently shadowed regions near the lunar poles, and may possibly produce "sparks" that could vaporize and melt the soil, perhaps as much as meteoroid impacts, according to NASA-funded research. This alteration may become evident when analyzing future samples from these regions that could hold the key to understanding the history of the moon and solar system.

Lowell Observatory to renovate Pluto discovery telescope

The instrument at Lowell Observatory used by Clyde Tombaugh to discover Pluto will soon undergo renovation. The year-long project, set to begin on January 12, will include restoration of both the historic telescope and the wooden dome that houses it. While the telescope will be removed from the dome during this work, the dome will be open from time to time for public tours as work allows.

NASA orders additional astronaut taxi flights from Boeing and SpaceX to the ISS

In a significant step towards restoring America's indigenous human spaceflight capability and fostering the new era of commercial space fight, NASA has awarded a slew of additional astronaut taxi flights from Boeing and SpaceX to carry crews to the International Space Station (ISS).

Specialized weaving techniques enable a new heatshield for planetary exploration

When the Galileo mission's probe entered the Jovian atmosphere in December 1995, it experienced temperatures twice as hot as the surface of the sun, and required carbon phenolic shields to protect its onboard payload from the intense heat. Since that mission, NASA has not flown a spacecraft that required protection from such extreme heat. Recently, however, the NRC Planetary Science Decadal Survey has recommended that NASA consider in situ science missions to Venus and Saturn as a high priority in the New Frontiers competed mission set. To reach the surface of these planets, missions will require heat shields that are capable of withstanding very extreme entry environments, but are not as heavy as the previously used carbon phenolic heat shields.

Could dark streaks in Venus' clouds be microbial life?

The question of life on Venus, of all places, is intriguing enough that a team of U.S. and Russian scientists working on a proposal for a new mission to the second planet—named Venera-D—are considering including the search for life in its mission goals.

Protecting dark skies for astronomy and life

Artificial light at night is a threat to astronomical research, personal safety, and the health of both humans and wildlife. The problem is worsening with the proliferation of LED billboards and blue-rich white light LEDs as an option for street lighting. Within five years, LED technology will take over as the dominant type of outdoor lighting technology. With this in mind, scientists and lighting engineers say now is the time to implement strategies for reducing light pollution. By working together, they are identifying the best type of LED to use while suggesting actions that minimize intrusive lighting.

A team of researchers at Baylor College of Medicine has developed a family-based association test that improves the detection in families of rare disease-causing variants of genes involved in complex conditions such as Alzheimer's. The method is called the rare-variant generalized disequilibrium test (RV-GDT), and it incorporates rare, as opposed to common, genetic variants into the analysis. In families in which several members are affected by a genetic condition, RV-GDT proved more powerful than other family-based methods in detecting rare genetic variants causing the condition. The results appear in the American Journal of Human Genetics.
