The Hubble Space Telescope has once again provided astronomers with invaluable insights into the mysteries of the universe.

Hubble spotted a rare off-center black hole shredding a star, revealing the first optical discovery of a wandering ...

ASKAP J0107–2347, located around 1.5 billion light-years away, is also remarkable because it features two sets of radio lobes ...

Scientists have never directly detected dark matter, but some wonder if one high-energy detection in 2023 could be a rare ...

The galaxy, known as SSTXFLS J172458.3+591545, has a deeply obscured black hole that is actively growing by consuming interstellar gas, known as an active galactic nucleus.

So, the high-energy particle wasn’t directly a dark matter particle, but rather a muon that decayed from dark matter likely fired from a blazar (a type of active galactic nucleus) right at Earth.

Thanks to its cosmic closeness, Hubble reveals exquisite details in NGC 4941, including individual star clusters and ...
