mercredi, 27 novembre 2019 à 18:30 - This visitor from another star is putting on quite a show for astronomers
Interstellar Comet Borisov is just a tiny dot in our night sky, visible only in the early morning hours before sunrise. Still, astronomers are capturing amazing new views of this visitor, using the very best telescopes available.
Since first spotted at the end of August, by amateur astronomer Gennadiy Borisov, our views of Comet C/2019 Q4 (Borisov), aka 2I/Borisov, have grown from a tiny smudge to this latest image. Taken using the Keck Telescope in Hawaii by Yale astronomers Pieter van Dokkum, Cheng-Han Hsieh, Shany Danieli and Gregory Laughlin, it is our best look at the comet, yet.
