Hubble examined the wreckage of the nucleus of comet ATLAS

Space telescope “Hubble” has received the most detailed to date image of the disintegrated nucleus of comet C/2019 Y4 (ATLAS), which could become the brightest for the last seven to ten years. It shows a lot of divergent from each other of the wreckage, reported on the portal of The Astronomer”s Telegram.

Long-period comet C/2019 Y4 (ATLAS) was discovered on 28 December 2019 by ground automated system of telescopes ATLAS (Asteroid Terrestrial-impact Last Alert System), the period of its revolution around the Sun is estimated at 5476 years. Its perihelion the comet will pass may 31, 2020, once inside the orbit of mercury and Earth most closer 23 may 2020, being at a distance of 0.78 astronomical units from our planet.

Previously, it was expected that the comet will become very bright object in the middle of may, but in early April it became clear that this may not happen, because the core beginning to crumble.

20 APR 2020 space telescope “Hubble” has received the most detailed to date image of the nucleus of comet C/2019 Y4 (ATLAS). It shows two main core fragment A and B, each of which consists of one or two bright components and a few dimmer, located at a distance of four arc seconds from each other along their common trajectory. Fragments C and D may represent an accumulation of smaller debris. At the time of the observations the comet was at a distance of 1.10 astronomical units from the Sun and at a distance of 0.98 astronomical units from Earth.

Currently, to see the wreckage of the nucleus of comet by Amateur astronomers using large telescopes with a diameter of 15 inches — now C/2019 Y4 (ATLAS) is moved in the Giraffe constellation and visible throughout the night high above the horizon.

Earlier we talked about how the Hubble has confirmed the beginning of the destruction of the core the first ever interstellar comet Borisov after its close approach to the Sun.
