Physicists have long believed that black holes explode at the end of their lives, and that such explosions happen—at most—only once every 100,000 years. But new research published in Physical Review ...

A tiny particle that smashed into Earth with a record-shattering energy of 220 petaelectronvolts could be the last scream of ...

Primordial black holes are hypothetical black holes thought to have formed moments after the Big Bang. Because they ...

New research suggests that there is a 90% chance that within the next decade, humanity could use a space or Earth-based ...

Some things we see in space appear to outpace light. Now we are learning to harness these bizarre optical illusions to ...

The early universe, fresh from the Big Bang, was a hot, dense soup of simple elements: hydrogen, helium, and trace amounts of lithium. But within a cosmic blink—just 100 to 200 million years after the ...

NASA has awarded Katalyst $30 million to move forward with implementation under a Phase III award as an existing participant in NASA’s Small Business Innovation Research (SBIR) Program, managed by the ...

A new article published in The Astrophysical Journal explores a new theory of how Type Ia supernovae, the powerful stellar ...

Using the largest catalog of exploding white dwarf vampire stars ever gathered has provided further evidence that dark energy, the mysterious force accelerating the expansion of the universe, is ...

A backward, mirror universe could explain the existence of dark matter. If an anti-universe exists, it would run backward in time, before the Big Bang. Dark matter, then, could be right-handed ...

The team explores one of the greatest discoveries of modern astronomy - that our universe is expanding - and the new ...

"We've been waiting to reach this point for a long time." Using the largest catalog of exploding white dwarf vampire stars ever gathered has provided further evidence that dark energy, the mysterious ...
