NASA starts designing futuristic space telescope to hunt for alien Earths

NASA's latest flagship telescope is still in its first year of science, but the agency isn't only hard at work building its successor — it's starting to plan that next mission's successor as well. In November 2021, a decadal document produced by the ...

Hungry black hole is transforming star into a stellar taffy and a cosmic donut

The All-Sky Automated Survey for Supernovae (ASAS-SN or "Assassin") first spotted the violent incident, referred to as a tidal disruption event (TDE), via a flash of high-energy radiation. The feast is taking place at the heart of a galaxy 300 million ...

Mars meteorite with organic molecules holds clues to chances of ancient life

A Martian meteorite that crashed in Morocco 11 years ago contains a vast diversity of organic compounds, which could help researchers discover if Mars could have hosted life and provide important clues about Earth's geological history.

Star on a dangerous path provides regular meals for supermassive black hole

In the eROSITA all-sky survey, scientists at the Max Planck Institute for Extraterrestrial Physics (MPE) have found an interesting repeating event. In an otherwise quiescent galaxy, an X-ray flare repeats every 220 days, indicating that a star orbiting ...

Hubble finds hungry black hole twisting captured star into donut shape

Black holes are gatherers, not hunters. They lie in wait until a hapless star wanders by. When the star gets close enough, the black hole's gravitational grasp violently rips it apart and sloppily devours its gasses while belching out intense radiation ...
