A new image of interstellar comet 3I/ATLAS shows it glowing green due to diatomic carbon, with its tail hidden from view. The comet, possibly the oldest ever observed and only the third interstellar visitor, is undergoing changes as it passes perihelion, providing valuable insights into its composition and origins. Despite some speculation, it is confirmed to be a natural comet from another star system.
During the September 2025 lunar eclipse, amateur astronomers captured images of interstellar comet 3I/ATLAS revealing a surprising green glow, possibly caused by diatomic carbon or other molecules, highlighting its unique chemistry and mysterious origins.
New photos of interstellar comet 3I/ATLAS suggest it may be turning bright green due to increased proximity to the sun, possibly caused by the release of rare chemicals like diatomic carbon or cyanide, but confirmation is pending as observations continue.
The "devil comet" 12P/Pons-Brooks, known for its distinctive horns, has lost its iconic feature after its latest eruption. However, astronomers have observed new characteristics, including a rare green hue and a mysterious shadow. The comet, a cryovolcanic comet with an icy nucleus, has had three major eruptions, each causing its coma to expand and appear brighter. The recent eruption was the most extreme, but the horns were absent this time. It is unclear why they have disappeared, but it is speculated that the frequent eruptions may have damaged the obstruction causing the horns. The comet will make its closest approach to Earth in June 2022.
