NASA's James Webb Space Telescope Could Potentially Detect the First Stars and Black Holes



Release date: April 25, 2018


Gravitational lensing by a galaxy cluster could bring the early universe into focus for Webb

One of the key science goals of NASA's James Webb Space Telescope is to learn about "first light," the moment when the first stars and galaxies lit the universe. While the first galaxies will be within Webb's reach, individual stars shine so faintly that Webb would not be able to detect them without help. That help could come in the form of natural magnification from gravitational lensing, according to a new theoretical paper.
