Using a technique that measures how much gravity bends light, astronomers say they have spotted early stars in galaxies more than 13 billion light-years away.
Images made by taking very deep exposures, then subtracting away all known light sources appear to show the light from the very first stars in the universe. Still up for debate but moving through the peer review system
Astronomer Phil Plait talks about a new discovery that might be able to describe the Universe that existed before the Big Bang.
Astronomers might have seen the very first stars in the universe. If so, these are incredible stars, some 1,000 times as massive as the Sun.
