A Cambridge-led study suggests comets rarely delivered useful quantities of life’s molecular ingredients to early Earth because impacts destroyed them and surviving material wouldn’t have stayed concentrated at the surface for long.
“Every one of these objects we study helps us understand a little more about how planets form around other stars.”
A rare look at a centaur transforming into a comet with coma is providing a missing link in the evolution of small, icy solar system bodies.
Comet McNaught brightened dramatically during two outbursts around perihelion as it made a close approach to the sun.
A shot so spectacular it will leave other astrophotographers green with envy.
Astronomers discovered that a near-Earth asteroid is actually a comet that could help scientists identify more hidden comets and improve planetary defense.
New research led by scientists at NASA’s Jet Propulsion Laboratory in Southern California has revealed the identity of a puzzling near-Earth object by precisely tracking its motion through space and using powerful observatories that image faint celestial objects. This object has a dual personality: Past images hadn’t revealed obvious cometlike activity, suggesting it might be […]
Observations of the fast-moving interstellar comet with the Very Large Telescope in Chile support similar observations made by the JWST.
A predawn Moon-and-planets meetup, a returning comet, a great chance to see the Milky Way, and Saturn’s rings at a new angle. Skywatching Highlights Transcript An early morning hangout with the Moon and planets, a comet swings by, prime time for the Milky Way, and Saturn’s rings shine at a new angle. That’s What’s Up […]
NASA’s James Webb Space Telescope is finding clues that are leading scientists toward the origins of the interstellar comet 3I/ATLAS.
