For the first time, astronomers have imaged dozens of belts around nearby stars where comets and tiny pebbles within them are ...

Harvard and Smithsonian (CfA), and its Submillimeter Array (SMA), were critical for identifying a cache of belts surrounding other stars beyond the sun where comets may reside. Regions around 74 stars ...

While it is already dimming after a close encounter with the sun, Comet C/2024 G3 (ATLAS) – also called the Great Comet of ...

New photos of comet C/2024 G3 (ATLAS) suggest that it could be disintegrating due to "thermal stress" from its recent slingshot around the sun. However, its fate is still unclear.

For this, astronomers used two facilities: the Submillimeter Array (SMA), CfA's eight-dish collection of radio telescopes in ...

Comet ATLAS (C/2024 G3) came within 8.3 million miles of the sun on January 13, reaching the perihelion of its massive, 160,000-year orbit through our solar system. The comet was only first ...

Oumuamua and Comet Borisov in 2017 and 2019, respectively, created a surge of interest. What were they? Where did they come ...

Comets are unpredictable, fleeting visitors in our sky, and C/2024 G3 (ATLAS) was no exception. This January, it graced the ...

"Our Sun (Sol) is marked by a black hexagon, and its orbital path is indicated by a grey solid line (top row only). Alpha Centauri's location and path are shown by a yellow star and a solid blue line ...

The number of planets that orbit the sun depends on what you mean by “planet,” and that’s not so easy to define ...

C/2024 G3 (ATLAS). A comet that hasn’t been in the inner solar system for around 180,000 years and is not likely to be seen again for 600,000 years, is suddenly visible after sunset—but only ...

Comet ATLAS (C/2024 G3) came within 8.3 million miles of the sun on January 13 as it reached its perihelion, and is now disintegrating.
