In a new study, scientists point to Hubble as a collection of two distant galaxies that are a good environment for studying cosmic evolution. The group of two galaxies, 220 million light-years from Earth, is called Arp 86 and is located in the constellation Pegasus. This set consists of the galaxy NGC 7753 and the much smaller companion NGC 7752.

About this Hubble's image said: "The small companion galaxy is almost connected to the main galaxy, and this structure has created ARP 86. The designation suggests that the pair of galaxies are located in the Atlas of Strange Galaxies compiled by astronomer Halton Arp in 1966. "ESA added:" Gravitational dance between the two galaxies eventually "NGC 7752 will be launched into intergalactic space or completely submerged in its larger neighbor." done. According to ESA, the space observatory examined stellar clusters, gas clouds and dust clouds in several environments in the neighborhood of the main subject, including other galaxies outside of ARP 86.

The Hubble Space Telescope data were then combined with Atacama Large Millimeter Array (ALMA) measurements to decompose young stars amid galactic dust. The research team, using Hubble and Alma, is looking for more information on how stars form.
This research will also contribute to the future work of the James Webb Space Telescope. The web launch, which has reached the launch site, is scheduled for late 2021 to help discover the origin of the universe once it orbits and launches scientific tools. One of the web research projects, according to ESA, is to look at dusty galaxies to learn more about stellar evolution. NASA, Dark Energy Survey, J. Dalcanton
