A super-Earth exoplanet has been detected within the habitable zone of a nearby red dwarf star, where liquid water might exist on its surface under the right atmospheric conditions.

The Solar Dynamics Observatory saw a lunar transit and an Earth eclipse on July 25 — the first when the moon passed between it and the sun, and another when Earth did the same.

Analysis of an ancient meteorite suggests that rocky planets both near and distant from the sun may have formed at the same time, challenging current models of our solar system’s evolution.

Two days this summer have been unusually short, with the shortest expected on Aug. 5, leading global timekeepers to consider adding a negative leap second.

Half a dozen fragments of the moon may briefly orbit Earth at any given time, before moving on to circle the sun, new research suggests.

Astronomers claim to have found new evidence supporting a controversial observation that our galaxy is residing in an unusually sparse region in space. If it's correct, it could rewrite cosmology.

You can see the recently identified "interstellar object" 3I/ATLAS shooting towards us through the solar system in a livestream from the Virtual Telescope Project.

Experts have confirmed that the mysterious object hurtling towards us, previously dubbed A11pl3Z, is an "interstellar object." The cosmic interloper, officially named 3I/ATLAS, is only the third of its kind ever seen — and will shoot past Earth later this year.

A newly discovered object, dubbed A11pl3Z, appears to be moving too fast and straight to have originated in the solar system. If confirmed, it will be the third interstellar visitor ever spotted.

There is currently a 4.3% chance that the giant space rock 2024 YR4 will hit the moon in seven years. If this does happen, debris from the nuclear bomb-like impact could trigger a "spectacular" meteor shower that will endanger Earth-orbiting satellites.
