Astronomers from Yale University have recently captured a close-up image of the interstellar comet 2l/Borisov. In case you are unknown, 2l/Borisov is the first pragmatic interstellar comet and the second experimental interstellar interloper, after Oumuamua – first known interstellar object discovered passing through the Solar System
During the end of October 2019, 2l/Borisov has passed through the ecliptic of the Solar System, and it is likely to make its closest approach to the Sun on December 8.
The close-up image was captured by astronomers - Cheng-Han Hsieh, Gregory Laughlin, Pieter Van Dokkum, and Shany Danieli on December 24, 2018 with the assistance of W.M. Keck Observatory’s Low-Resolution Imaging Spectrometer in Hawaii. A new close-up image has been created that displays what this interstellar comet would look like alongside Earth. According to Pieter Van Dokkum, its tail is around 100000-miles-long that is 14-times the size of the Earth.
Research Scholars further stated that 2l/Borisov was shaped way beyond our Solar System and was expelled into the space due to a near-collision with a planet in the original Solar System. According to Gregory Laughlin, interstellar comet 2l/Borisov is vanishing as it is getting near the Earth and is releasing fine dust and gas from its tail.
Astronomer Laughlin further said that “astronomers are taking advantage of Borisov’s visit, using telescopes such as Keck to obtain information about the building blocks of planets in systems other than our own.”
Research Scholars also mentioned that the interstellar comet’s solid nucleus is a mile wide and has taken a “ghostly appearance” due to the warming effect of the Sun.
