An astronomer captured one of the sharpest views of a comet outside our solar system.
David Jitt, a professor of planetary astronomy and astronomy at UCLA, studies Comet 2I / Borisov ("I" means "interstellar") using NASA's Hubble Space Telescope, which captured images of the object when it was about 260 million miles.
The comet travels at approximately 110,000 miles per hour.
Another interstellar object called "Oumuanua" is visible. by an astronomer at the University of Hawaii in 2017 before exiting our solar system.
"Oumaamawa looked like a bare rock, but Borisov was really active – more like a normal comet," said Juitt, who heads the Hubble team, in a statement. "The puzzle is why these two are so different. There is so much dust on this thing that we will have to work hard to dig the core. ”

The two comets, 2I / Borisov and "Oumuamua", are the first two objects to travel outside of our S a system in ours that has been observed.
This is possible because the knowledge and equipment of scientists are far better than they have ever been.
One study apparently claims that there are thousands of such comets in our solar system. they are thought to be fragments left when planets are formed in the outer regions of planetary systems.
