Through a phenomenon called gravitational lensing, three different moments in a far-off supernova explosion were captured in a single snapshot by NASA’s Hubble Space Telescope. The light from the ...

Thanks to a cosmic magic trick, the Hubble Space Telescope witnesses three different moments in a star's explosive death process. Freelance writer Amanda C. Kooser covers gadgets and tech news with a ...

Measuring the distance to truly remote objects like galaxies, quasars, and galaxy clusters is a crucial task in astrophysics, particularly when it comes to studying the early universe, but it's a ...

This week’s image from the Hubble Space Telescope shows a stunning view of a spiral galaxy called UGC 12295, located nearly 200 million light-years away. This galaxy appears face-on from Earth, ...

NASA’s Hubble Space Telescope has identified a star that was one million times brighter than the Sun before it exploded as a supernova in 2005. According to current theories of stellar evolution, the ...

A spectacular cosmic event nicknamed “SN Winny” could help solve one of astronomy’s biggest mysteries: how fast the universe is expanding. This rare superluminous supernova, located 10 billion ...
