Rocky Planets May Have Started Forming Just 100 Million Years after Big Bang
New simulations suggest supernova explosions of the Universe’s first stars scattered the ingredients for rocky planets only 100…
Astronomers Discover a Brand-New Type of Object: Part Black Hole, Part Star
At the cosmic dawn, the universe was sprinkled with giant black holes—monstrosities so huge that scientists are still…
Vigorous turbulence driven by quasar-mode feedback in a cluster core
The X-Ray Imaging and Spectroscopy Mission (XRISM)1 is the successor to the Hitomi X-ray observatory2, which ceased operations…
Dark matter may be naturally tuned to a hidden fifth dimension
Dark matter appears to hold galaxies together, yet it has never shown itself directly. A new theory suggests…
