Astronomers using ESO’s Very Large Telescope have detected, in another galaxy, a stellar-mass black hole much farther away than any other previously known. With a mass above fifteen times that of the Sun, this is also the second most massive stellar…
Image Caption: An international team led by astronomers at the University of Hertfordshire have discovered what may be the coolest sub-stellar body (a brown dwarf) ever found outside our own solar system. The team’s findings have been accepted for publ…
A newfound black hole that’s left over from the explosion of a star is the most distant yet to be discovered by astronomers.

Astronomers studying two exploding stars, or supernovae, have found evidence the blasts received an extra boost from newborn black holes.

Fainter broadcasting signals and digital switchover mean Earth will soon be undetectable to extraterrestrialsHuman beings are making it harder for extraterrestials to pick up our broadcasts and make contact, the world’s leading expert on the search for alien life warned yesterday.At a special meeting on the search for extraterrestrial intelligence (Seti), the US astronomer Frank [...]
New findings could help astronomers understand more about dark matter, as well as its even stranger sibling — dark energy.

For decades, astronomers have analyzed the impact that asteroids could have on Earth. New research by MIT Professor of Planetary Science Richard Binzel examines the opposite scenario: that Earth has considerable influence on asteroids and from a di…
A newfound “comet” traveling in an unusual orbit may actually be fallout from the explosive collision of two asteroids, say astronomers who recently spotted the fuzzy, tailed object.
