The interstellar comet Borisov, which flew past Earth in December, is full of carbon monoxide ice that implies its home star is smaller and colder than our sun

Astronomers using NASA’s Neil Gehrels Swift Observatory have tracked water loss from 2I/Borisov, the first known interstellar comet to visit our Solar System, as it approached and rounded the Sun. Their findings were published in the Astrophysical Journal Letters. 2I/Borisov was detected on August 30, 2019 by Gennady Borisov, an astronomer at the Crimean Astrophysical [...]
