For some comets, gas and dust might escape more or less evenly over the comet's entire surface, like a melting ice cube. In other cases, gas and dust may escape from a specific location in a preferred ...

Experts think the comet started breaking up last week, but it's still putting on a show for star gazers for a few more days.

This is similar to how Comet Lovejoy (C/2011 W3) disintegrated in 2011, which survived its journey a mere 87,000 miles above ...

Comet G3 ATLAS faced just such a perilous passage, reaching perihelion 14 million kilometers from the Sun on January 13th.

Comet ATLAS G3 will be closest to the Sun on Jan. 13, 2025, but will mainly be visible only from the Southern Hemisphere.

G3 has mesmerized astronomers and amateur skygazers for months as the world tried to spot the bright comet in the sky nearing its fatal encounter with the Sun.

When a comet gets close to the sun, the sunlight heats up the ice, causing it to sublimate, or transition from an ice to a gas. After this transition happens, the gas is blown off the surface of ...

This comet, named ATLAS after the Asteroid Terrestrial-impact Last Alert System that discovered it, reached an extraordinary ...

As a comet approaches the sun, it begins to heat up. The ice on and near the surface "sublimes", causing jets of gas and dust to erupt from the nucleus's surface. This shrouds the nucleus in a ...

Comet ATLAS, or C/2024 G3 to astronomers ... and come within 8.4 million miles of the solar surface. Some comets disintegrate from the heat. But if they survive the encounter, perihelion is ...

Michigan State University and NASA researchers discover seven dark comets that reveal new solar system secrets.

Second, said quoted magnitude for a comet gets "smeared out" over its apparent surface area, knocking the comet's apparent brightness down a notch or two. We can hope that Comet G3 ATLAS is an ...
