The near-Earth asteroid Kamo'oalewa was indeed ejected from the moon, a new study confirms, suggesting more lunar fragments dwell among near-Earth asteroids.
What astronomers can measure using telescopes is not what we really want to know – instead, we calculate the properties we're interested in studying by observing and interpreting apparent properties from afar.
Evidence pointing toward the possible existence of “Planet 9” lurking at the edge of the solar system may actually mean we need to revise our recipe for gravity.
"For years, he had the field of planetary formation, which he had created, virtually to himself. Most Soviet colleagues were skeptical and uninterested; his research appeared so speculative, so far removed from any evidence."
NASA will extend the New Horizons mission through 2028 or 2029, allowing the spacecraft to continue studying its exotic environs far from the sun.
A new class of proteins found in methane deposits on Earth's seafloor could help inform the search for alien life.
This year's final supermoon, September's Harvest Full Moon, rises on Friday, Sept. 29, bringing a summer of supermoons to a close and joined by a planetary parade of Jupiter, Saturn, and Mercury.
The return capsule of NASA's OSIRIS-REx mission is scheduled to touch down in Utah on Sept. 24, bearing samples of asteroid Bennu. Here's how to watch the event live.
The outer solar system contains a striking crime scene with a big mystery: How did Neptune get a moon like Triton?
A hypothetical Kuiper Belt Planet adds to the list of possibly undiscovered worlds in our solar system. Also on that list? Planet Nine.
Venus is approaching 'inferior conjunction' as it swaps from being the 'Evening Star' to the 'Morning Star,' passing between Earth and the sun in the meantime.
Swapna Krishna, author of the new book "Stargazing: Contemplating the Cosmos to Find Inner Peace," writes a guide to getting the most out of the night sky wherever you are.
