This is the most comprehensive X-ray map of the sky ever made
A new X-ray map of the entire sky, using data from the eROSITA telescope’s first full scan, looks deeper into space than any other of its kind.

Self-destructive civilizations may doom our search for alien intelligence
A lack of signals from space may also be bad news for Earthlings.

Some exoplanets may be covered in weird water that’s between liquid and gas
“Supercritical” water, a corrosive substance used to break down toxic waste on Earth, coats some small worlds around other stars, simulations suggest.

A newfound exoplanet may be the exposed core of a gas giant
A planet about 734 light-years away could be a former gas giant that lost its atmosphere or a failed giant that never finished growing.
