Observing the interactions between dark matter and so-called "dark photons" during a period after the Big Bang called the "cosmic dawn" could help shed light on the universe's most mysterious and ...

By looking at light from distant exploding stars called supernovas, in 1998 astronomers discovered the universe isn’t just expanding – its expansion is speeding up. But what’s behind this acceleration ...

Astronomers used NASA's James Webb Space Telescope to reveal 44 stars in a galaxy so far away, its light dates to when the universe was half its age.

NASA's James Webb Space Telescope has captured a unique image that revealed 44 individual stars in a galaxy 6.5 billion light ...

Using NASA's James Webb Space Telescope, scientists have observed a galaxy nearly 6.5 billion light-years from Earth, and ...

Taking advantage of a cosmic 'double lens,' astronomers resolved more than 40 individual stars in a galaxy so far away its light dates back to when the universe was only half its present age.

Astronomers used JWST and gravitational lensing to spot 44 individual stars in a galaxy 6.5 billion light-years away.

A phenomenon called gravitational lensing turned a galaxy into a "hall of mirrors of cosmic proportions," allowing for the discovery.

The Hubble Space Telescope is nearing its 35th anniversary and skywatchers can celebrate the mighty telescope with a ...
