Astronomers find fastest-growing black hole known in space
Astronomers at ANU have found the fastest-growing black hole known in the Universe, describing it as a monster that devours a mass equivalent to our sun every two days.
Orbital variations can trigger 'snowball' states in habitable zones around sunlike stars
Aspects of an otherwise Earthlike planet's tilt and orbital dynamics can severely affect its potential habitability—even triggering abrupt "snowball states" where oceans freeze and surface life is impossible, according ...
Old NASA spacecraft points to new evidence of watery plumes over Europa
A fresh look at data from a 1997 flyby of Jupiter's moon, Europa, suggests that NASA's Galileo spacecraft flew directly through a watery plume, raising hopes of probing the jets for signs of life around the second planet ...

A Multiverse—where our Universe is only one of many—might not be as inhospitable to life as previously thought, according to new research.
Dozens of binaries from Milky Way's globular clusters could be detectable by LISA
The historic first detection of gravitational waves from colliding black holes far outside our galaxy opened a new window to understanding the universe. A string of detections—four more binary black holes and a pair of ...
