ABSTRACT. The search for extraterrestrial intelligence is currently being pursued using multiple techniques and in different wavelength bands. Dyson sphere

Neutron stars and stellar-mass black holes are the remnants of massive star explosions1. Most massive stars reside in close binary systems2, and the interplay between the companion star and the newly formed compact object has been theoretically explored3, but signatures for binarity or evidence for the formation of a compact object during a supernova explosion are still lacking. Here we report a stripped-envelope supernova, SN 2022jli, which shows 12.4-day periodic undulations during the declini...

White dwarfs, the extremely dense remnants left behind by most stars after their death, are characterized by a mass comparable to that of the Sun compressed into the size of an Earth-like planet. In the resulting strong gravity, heavy elements sink towards the centre and the upper layer of the atmosphere contains only the lightest element present, usually hydrogen or helium1,2. Several mechanisms compete with gravitational settling to change a white dwarf’s surface composition as it cools3...

The Milky Way is older than astronomers thought, or part of it is. A newly-published study shows that part of the disk is two billion years older than we thought.

The Milky Way isn't exactly a young buck.

The surprising result came from analysis by astronomers Maosheng Xiang and Hans-Walter Rix, from the Max-Planck Institute for Astronomy, Heidelberg, Germany.

Gia’s Early Data Release 3 – Travel of 1.6 million stars across the sky It is frightening to look into the future up to 1.6 million years – but it is also important to note that the measurements here predict the Sun’s acceleration due to the gravitational pull of the Milky Way. This does not mean that it is just a prediction of where the sun will go. Acceleration of the barcentreThe center of mass of the universe, the animation really shows how it can be seen from a solar point of view...
