An astronomer has focused one of the sharpest looks from outside our solar system on a comet.
David Jewitt, professor of planetology and astronomy at UCLA, studied comet 2I / Borisov (the "I" stands for "interstellar"). ) using NASA's Hubble Space Telescope, which took pictures of the object when it was about 260 million miles away.
The comet moves at a speed of about 110,000 miles per hour.
Another interstellar object, called "Oumuanua," was seen by an astronomer from the University of Hawaii in 2017, before it raced out of our solar system.
"Oumuamua looked like a bare rock, but Borisov is really active ̵

The two comets 2I / Borisov and & # 39; Oumuamua & # 39; are reportedly the first two objects that have come from outside our solar system into our observed.
This is possible because the knowledge and equipment of scientists are far better than ever.
One study apparently claims that there are thousands of such comets in our solar system, but most are too weak to be discovered with current telescopes.
Comets are ice bodies that are believed to be fragments that remain when planets form in the outer reaches of planetary systems.
