A serendipitous flythrough of the tail of a disintegrated comet has offered scientists a unique opportunity to study these remarkable structures, in new research presented…
A newly discovered visitor to the outer edges of our Solar System has been shown to be the largest known comet ever, thanks to the…
A cluster of comet fragments believed to have hit Earth nearly 13,000 years ago may have shaped the origins of human civilization, research suggests. Possibly…
As anyone who has ever tried to clean a home knows, ridding yourself of dust is a Sisyphean effort. No surface stays free of it…
Researchers report that they can detect showers from the debris in the path of comets that pass close to Earth orbit and return as infrequently…
The world’s first ground-based observations of the bare nucleus of a comet nearing the end of its active life revealed that the nucleus has a…
Studying the creation and evolution of sulfur-containing compounds in outer space is essential for understanding interstellar chemistry. CS2 is believed to be the most important…
New observations with the European Southern Observatory’s Very Large Telescope (ESO’s VLT) indicate that the rogue comet 2I/Borisov, which is only the second and most…
In early 2016, an icy visitor from the edge of our solar system hurtled past Earth. It briefly became visible to stargazers as Comet Catalina…
Comet Comes in from the Cold and Finds an Off-Ramp on Its Sunward Journey Long road trips can be tedious and boring. That’s why many…
New theory explains possible origin of the Armageddon-causing object. It forever changed history when it crashed into Earth about 66 million years ago. The Chicxulub…
It was tens of miles wide and forever changed history when it crashed into Earth about 66 million years ago. The Chicxulub impactor, as it’s…
When scientists downlinked data from Parker Solar Probe’s sixth orbit, there was a small, bright surprise waiting for them: the spacecraft’s first observation of a…
As Chile and Argentina witnessed the total solar eclipse on December 14, 2020, unbeknownst to skywatchers, a little tiny speck was flying past the Sun…
Researchers have discovered a new superhighway network to travel through the Solar System much faster than was previously possible. Such routes can drive comets and…
A unique stage of planetary system evolution has been imaged by astronomers, showing fast-moving carbon monoxide gas flowing away from a star system over 400…
An international study led by the University of Turku discovered phosphorus and fluorine in solid dust particles collected from a comet. The finding indicates that…
