Leave it to the good old Hubble Space Telescope. The Hustler Telescope has given us a photo of the new interstellar comet 2I / Borisov. Take that, imagine new telescopes.
2I / Borisov has migrated from the cold of interstellar space into our solar system, but no one knows where it came from or how long it was on the way. Boris is just the second object that we have observed in our solar system, which has entered our solar system from somewhere in the galaxy, and the Hubble camera has taken photos of it, traveling at a speed of about 177,000 km / h (110,000 mph) .) Progress. So far, the Hubble images are the sharpest yet.
Our first interstellar visitor was Oumuamua, who flew through our solar system in 2017. But this object did not reveal its secrets so easily. It came and went and generated a lot of clicks and guesses and panic headlines in a few quarters. But it had no coma and no tail, which means it had no ice. But Boris is clearly a comet.
Comets contain a lot of water ice and other volatile substances. When they get close enough to the sun, part of the ice sublimates into gas, producing the characteristic coma and tail that is evident in many comet images. In these Hubble images by 2I / Borisov a coma and a tail are clearly visible.
"While Oumuamua seemed like a rock, Borisov is really active, more like a normal comet. It's a mystery why these two are so different, "said David Jewitt of the University of California at Los Angeles (UCLA) in a press release. Jewiit is the leader of the Hubble team who watched the comet.
