Ever since 2I/Borisov was first discovered, astronomers have been fascinated with this interstellar comet. With new information being discovered about the comet, experts have confidentially called it the most “pristine” space object that’s ever been studied.
Astronomers don’t think that 2I/Borisov ever traveled close to any star (other than our sun) which means that its composition of gas and dust was completely pure and original. When comets travel close to stars, they can become altered or degraded by the sun’s radiation and heat. Stefano Bagnulo, who is from the Armagh Observatory and Planetarium, Northern Ireland, UK, and who led the new study, stated, “2I/Borisov could represent the first truly pristine comet ever observed.”
