NASA’s Hubble Space Telescope has given astronomers their best look yet at an interstellar visitor—comet 2I/Borisov—whose speed and trajectory indicate it has come from beyond our solar system.
A spokesperson for US-based space agency NASA wrote in a statement: “This Hubble image, taken on October 12, 2019, is the sharpest view of the comet to date.
Hubble reveals a central concentration of dust around the nucleus, which is too small to be seen by Hubble.”
Comet 2I/Borisov is only the second such interstellar object known to have passed through the Solar System.
In 2017, the first identified interstellar visitor, an object dubbed ‘Oumuamua, swung within 24 million miles of the Sun shortly before hurtling out of the Solar System.
