Astronomers found a high energy neutrino – a cosmic ray – that apparently originated during a “tidal disruption event,” that is, when a supermassive black hole shredded a distant star.

For the first time, astronomers have detected the vaporized remains of the crusts of long-dead Earth-like and Mars-like planets in the atmospheres of white dwarf stars.

A new study suggests that our Milky Way galaxy is filled with planets like Earth, containing continents and oceans. If so, life might be common in the Milky Way.

To the extent that we can see them, galaxies in the very early universe should look relatively young and unformed. But galaxy ALESS 073.1 is a surprise to astronomers: it looks more mature than we’d have any reason to expect. Why?

Particles carried from Earth’s poles via our planet’s magnetosphere could be interacting with lunar rocks to create small quantities of water on the moon.

A new atlas of nearby binary stars plots more than a million pairs and reveals a profusion of identical twins.

The James Webb Space Telescope is the world’s most complex infrared telescope, built for a wide range of research projects. NASA is now targeting October 31 for its launch on an Ariane 5 rocket from French Guiana.

NASA’s Perseverance mission conducted a picture-perfect landing on Mars today and has already sent back several images.

Researchers at the SETI Institute say that mysterious dark streaks on sun-facing slopes on Mars, debated about for years, may be small landslides caused by a combination of salts and melting ice just below the surface.

Astronomers have confirmed that an object with the nickname of Farfarout is, to date, the farthest object we’ve seen in the solar system.

Until recently, magnetic fields in the outskirts of galaxies were too faint to be detected. Although it’s still not clear what causes them or how they’re maintained, astronomers have started to create images of their observations of galaxies’ magnetic fields producing beautiful aurora-like effects. See them here.
