Astronomers have pulled off an unprecedented feat: detecting ultra-faint light from the Big Bang using ground-based telescopes. This polarized light scattered by the universe's very first stars over ...

"Using the new common signal, we can determine how much of what we're seeing is cosmic glare from light bouncing off the hood ...

But the universe’s initial moments after the cataclysmic explosion, including how its earliest stars influenced the light we ...

NASA's Chandra X-ray Observatory has detected powerful black hole jets emanating from a galaxy 11.6 billion light-years away.

For the first time, astronomers have used a ground-based telescope to observe polarized microwave light from the universe's ...

From a Mars rover selfie to an astronaut's view of the flower moon, these space images will give you a new perspective on our ...

Jeremy Darling’s novel approach applies astrometry to detect the gravitational wave background, offering new insights into the early universe and large-scale cosmic events.

A black hole has blasted out a surprisingly powerful jet in the distant universe, according to a new study from NASA's ...

Marie Curie worked with radioactive material with her bare hands. More than 100 years later, Sophie Hardach travels to Paris ...

Abstract: A charged particle which travels a dielectric medium with a velocity greater than the light one will generate Cherenkov radiation in a wide range of frequencies. In this paper we presented a ...

You could swim through the deepest voids and encounter a single hydrogen atom in an entire football field's worth of space.

The earliest galaxies may have scrambled our reading of the Universe. A new study challenges the traditional interpretation of the cosmic microwave background, this fossil light from the Big Bang.
