A new study claims that most comets and asteroids in the Solar System might have interstellar origins, suggesting that we live in a cosmic melting pot.
Comet Atlas may have originated from a 5,000-year-old comet that swung by the sun. It is claimed to be the sister of a comet observed in 1844. Although Comet Atlas broke down, its sister has survived.
NASA and the European Space Agency’s Solar Orbiter flew over near the remnants of comet ATLAS to find what happened to its tail after its disintegration in April 2020.
Aurora or the northern lights have been confirmed on comet 67P/Churyumov-Gerasimenko but is unlike Earth's light show. The invisible aurora, triggered by solar particles, may provide more information on how solar wind affects space weather.
