Every few thousand years, an unlucky star wanders too close to the black hole at the center of the Milky Way. The black hole's powerful gravity rips the star apart, sending a long streamer of gas whipping outward. That...
Interstellar forecast for a nearby star: Raining comets! NASA's Hubble Space Telescope has discovered comets plunging onto the star HD 172555, which is a youthful 23 million years old and resides 95 light-years from Earth. The exocomets comets outside our...
The Moon, and the question of how it was formed, has long been a source of fascination and wonder. Now, a team of Israeli researchers suggests that the Moon we see every night is not Earth's first moon, but...
Searching for planets around other stars is a tricky business. They're so small and faint that it's hard to spot them. But a possible planet in a nearby stellar system may be betraying its presence in a unique way:...
An unparalleled image from NASA's Chandra X-ray Observatory is giving an international team of astronomers the best look yet at the growth of black holes over billions of years beginning soon after the Big Bang. This is the deepest...
An international team of astronomers, including Lancaster's David Sobral, has discovered a cosmic one-two punch never seen before. Two of the most powerful phenomena in the Universe a supermassive black hole and the collision of giant galaxy clusters have combined...
Using a model similar to what meteorologists use to forecast weather on Earth and a computer simulation of the physics of evaporating ices, a new study published in the journal, Nature by York University's Professor John Moores, Department of...
This galaxy has a far more exciting and futuristic classification than most it hosts a megamaser. Megamasers are intensely bright, around 100 million times brighter than the masers found in galaxies like the Milky Way. The entire galaxy essentially...
The Australian National University (ANU) is part of an international team of astronomers that found one of the Universe's biggest superclusters of galaxies near the Milky Way. Professor Matthew Colless from ANU said the Vela supercluster, which had previously gone...
Boron has been identified for the first time on the surface of Mars, indicating the potential for long-term habitable groundwater in the ancient past. This finding and others from NASA's Curiosity rover science team will be discussed in a...
