Cosmic Rose Image by NASA

23 April 2021 Current Affairs:The National Aeronautics and Space Administration (NASA) shared an image of “Cosmic Rose”. Cosmic Rose is an image captured via the Hubble Space Telescope of NASA. The photo featured interacting galaxies Arp 273.

Highlights:
♦ Arp 273: It lies in the Andromeda constellation. Arp 273 is 300 million light-years away from the earth. Arp 273 is a combination of spiral galaxy UGC 1810 and UGC 1813. UGC 1810 is 5 instances heavier than UGS 1813. And, UGC 1810 has a disc that is tidally distorted into a rose shape. The distortion is on the whole due to the gravitational pull of UGC 1813 that lies beneath. This has been captured through Hubble Space Telescope.
♦ The Interacting Galaxies are these galaxies whose gravitational fields disturb one another. 
♦ The Galaxy harassment is an interaction between a low-luminosity galaxy and a brighter one. It is commonly frequent in prosperous galaxy clusters such as Coma and Virgo.
♦ Galactic Cannibalism: It is a process the place a giant galaxy interacts with a partner through tidal gravitational interactions. The galactic tide is defined as pressure skilled by objects subjected to the gravitational area of a galaxy.
♦ Galaxy Collision: These are frequent at some point of galaxy evolution. In these interactions, two galaxies will collide and will no longer have ample momentum to proceed travelling after the collision.
♦ Galaxy Mergers: A galaxy merger occurs when two or greater galaxies collide with every other. They are the most violent kind of galaxy interactions. Galaxy mergers are enormously essential as they are the necessary measure of Galaxy evolution.
♦ Hubble Space Telescope: It is space telescope that used to be launched in 1990 into low Earth Orbit.
