An international team of astronomers has conducted optical and near-infrared observations of a supernova designated SN ...

From a small island off the coast of Panama to the farthest reaches of space, the Smithsonian advanced our knowledge of the ...

Since the time of the Big Bang, the existence of supermassive black holes only 1 billion years old has left astronomers utterly perplexed. It would not be possible for regular stars to develop black ...

The new paper argues that, in SN 1181, the first phase of the supernova fizzled out and left behind an unusually active ...

Scientists have detected the most distant supernova ever seen, exploding when the universe was less than a billion years old.

An international team of astronomers has achieved a first in probing the early universe, using the James Webb Space Telescope ...

Earlier this year, a powerful gamma-ray burst traveled through space from a very distant source in the cosmos. The explosion was traced back to the early universe, just millions of years after the Big ...

In a strange turn of events, a supernova birthed twin baby neutron stars that merged to make a powerful kilonova. Reading time 3 minutes When massive stars die, they go out in fiery explosions called ...

A massive star may have burst, leaving behind two dense, dead cores, which then collided and caused another explosion ...

In other words, Earth's birth appeared to depend on an event that was possible, but extremely rare. As a researcher working on supernova physics and cosmic rays, this explanation felt incomplete.
