Jupiter's moons hide giant subsurface oceans.

The Moon may have been captured during a close encounter between a young Earth and a terrestrial binary (a system of the Moon and another rocky object), according to a new paper published in the Planetary Science Journal.

Astronomers using the James Webb Space Telescope have spotted a rare galaxy at the dawn of time that may be a "missing link" between the oldest generation of stars and the ones we see near Earth.

Astronomers are getting better at spotting asteroids, such as the asteroid that hit Earth near the Philippines on September 5, 2024. Read more. The post We're getting better at seeing asteroids that may hit Earth first appeared on EarthSky.

Astronomers study stars by looking at the different colors of light they emit—colors they capture and analyze using spectroscopy. Now a team led by Université de Montréal's Étienne Artigau has developed a technique that uses a star's spectrum to chart variations in its temperature to the nearest tenth of a degree Celsius, over a range of time scales.
