22 hours ago · Comet C/2024 G3 (ATLAS) wagging its tail. J. Beltrán/ESO. A closer view shows the distinct tails of Comet C/2024 G3 (ATLAS); even after its nucleus has broken apart, these tails are formed by the ...

A comet tail and coma are visible features of a comet when they are illuminated by the Sun and may become visible from Earth when a comet passes through the inner Solar System. As a comet approaches the inner Solar System, solar radiation causes the volatile materials within the comet to vaporize and stream out of the nucleus , carrying dust ...

Between January 11 and 15, 2025, a bright comet streaked across images taken by the ESA (European Space Agency) and NASA ’s SOHO (Solar and Heliospheric Observatory) spacecraft. Known as C/2024 G3 (ATLAS), the comet reached its closest point to …

Sep 12, 2024 · The Sun’s radiation pressure shapes comet tails, always pointing them away from the Sun. Comets have two distinct types of tails: a dust tail and a gas tail. The dust tail appears curved and fuzzy, while the gas tail is straighter and bluer. Comet tail particles reach speeds of up to 100 km/s as they stream away from the nucleus.

Dec 20, 2023 · Comet tails point away from the Sun, aligning with the solar wind, with the dust tail curving toward the comet’s path. Surrounding the coma and part of the tails is an invisible, irregular cloud called the hydrogen envelope.
