NASA reported a mysterious "jellyfish" galaxy known as ESO 137-001. Young blue stars hanging on its tail.
Like the galaxy's disk, cosmic traps are made up of 260,000 light-years of gas in space long. The "Jellyfish" galaxy was first seen in 2014 by the Chandra X-ray Observatory and the Hubble Space Telescope.
ESO 137-001 is a barred spiral galaxy, similar to the size of the Milky Way. It is located in the southern constellation Triangulum Australe and is approximately 220 million light years from Earth. It is also part of a group of galaxies named Abell 3627.
Its long, gaseous tail is full of newborn stars, and scientists especially want to know the secret behind the incident.
According to NASA, young stars formed in the tail of the galaxy should be almost impossible because large processes of galaxies should be difficult to show common processes for new stars.
Places between galaxies are filled with hot gas. This gas works like a headwind, when it is drawn by galaxies residing in the cluster, which results in a process called "RAM pressure pressure".
In the affected galaxies, the Ram pressure slow down the stripping star formation, which is why scientists are curious about star formations in the ESO 137-001. The process of separation should heat the gas, but surprisingly, it did not happen.
"We think it is difficult to snatch a molecular cloud which is already producing stars because it must be tightly bound by gravity. Which means that we are wrong, or this gas stops and heats up, But again it had to be cooled again so that it could become condensate and build stars, "said Stacey Albert's of Arizona University, a co-investigator on the project.
She said, "Telling these two scenarios individually is something we want to achieve."
The James Webb Space Telescope is the key to understanding ESO 137-001. It has been launched in 2021.
According to NASA, the James Web telescope will point to targeted sites of star building in various areas around the tail: near its end, in the middle, and near the galaxy.
This will help scientists to know how the stripping process evolved over time and how it affected the conditions of the new stars.
A special tool has been established to investigate the mysterious galaxy in the web, which is called mid-infrared instrument). In the comments of MIRI, 50 infrequent spatial expansions and 20 times better spectral details will be provided by other infrared observatories than previous work.
In addition to solving the secrets of ESO 137-001, the telescope is also capable of examining the mysterious structures and genesis of the universe, as well as able to see beyond the distant world around the other stars.
The entire project was made possible with the cooperation of NASA, Canadian Space Agency and European Space Agency.
