The interstellar visitor 2I/Borisov broke
After several outbursts of brightness, images from the Hubble Space Telescope show that the core of the interstellar comet split in two at the end of March 2020. Just a week later, the smaller fragment had dissolved in the form of a cloud of dust.
Observations by the Hubble Space Telescope indicate that interstellar visitor 2I/Borisov broke apart in late March 2020. While the images from March 23, 2020 still showed a single bright nucleus in the center of the comet's envelope, the coma, the object appeared clearly elongated in images from March 30 (see images above). At that time, the two fragments were about 180 kilometers apart, as reported by a group of researchers led by David Jewitt from the University of California in "Astronomer's Telegram". Another working group estimated the detached fragment to be less than 100 meters in diameter. This is actually not a significant loss, because the core of 2I/Borisov may have previously had a total diameter of about 400 meters. Assuming a spherical shape, it lost just under two percent of the volume. The current observation
