Astronomers have discovered the biggest explosion seen in the Universe in a galaxy cluster 390 million light years away. At the center of the Ophiuchus galaxy cluster, there is a supermassive black ...

Here’s what you’ll learn when you read this story: Primordial black holes are hypothetical black holes thought to have formed moments after the Big Bang. Because they supposedly formed about 14 ...

A new study by physicists predicts that the universe could one day collapse in a reverse Big Bang, offering fresh insight into how it might all end.

Astronomers from the University of Hawaii’s Institute for Astronomy have identified a new category of events that they found to be much more powerful than gamma-ray bursts, called extreme nuclear ...

Astronomers are trying to understand what caused a series of gamma ray bursts, or GRBs — the most powerful explosions in the universe. These energetic bursts are typically unleashed by the incendiary ...

More than 13 billion years ago, before planets, before even most of the heavier elements that make them, the first stars ...

Gamma ray bursts are some of the most powerful explosions in the universe, unleashing as much energy in mere seconds as the Sun will in its entire 10 billion year lifespan. Typically, they’re produced ...

Gamma-ray bursts (GRBs) are the most energetic and luminous explosions in the universe. However, they are fleeting and often ...

Their research, published in The Astrophysical Journal, suggests that tiny primordial black holes (PBHs) could trigger these ...

The universe is approaching the midpoint of its 33-billion-year lifespan, a Cornell physicist calculates with new data from ...
