A uncommon interstellar comet — solely the third ever confirmed to enter our photo voltaic system — was photographed final week, carefully approaching Mars, the European Space Agency mentioned Tuesday.
The photographs taken on Friday by two Mars orbiters present a shiny, fuzzy white dot of the comet, often known as 3I/ATLAS, showing to maneuver towards a backdrop of distant stars because it was about 18,641,135 miles away from Mars. The comet poses no menace to Earth, NASA has beforehand mentioned.
“This was a very challenging observation for the instrument,” Nick Thomas, principal investigator of the CaSSIS digital camera, mentioned in a statement. “The comet is around 10,000 to 100,000 times fainter than our usual target.”

Since its discovery in July, comet 3I/ATLAS has been photographed a number of instances. In early August, NASA and the European Space Agency shared photographs taken by the Hubble Space Telescope, which captured the comet from about 277 million miles away.
Last month, a new picture confirmed the rising tail of 3I/ATLAS from one other star system streaking throughout our photo voltaic system.
NASA has mentioned the comet will make its closest strategy to the solar in late October, passing between the orbits of Mars and Earth. It ought to stay seen by way of September earlier than transferring too near the solar to look at, reappearing on the alternative facet in early December.
The European Space Agency mentioned Tuesday that scientists will hold analyzing knowledge from each orbiters, combining a number of photographs from Mars Express within the hope of detecting the faint comet.
Interstellar comets are very uncommon, astronomers mentioned. Only two different examples have ever been confirmed: 1I/’Oumuamu in 2017 and 2I/Borisov in 2019.
