NASA reports a huge galaxy "Medusa" with 260,000 gas gas tail

NASA reported a mysterious galaxy "jellyfish", known as ESO 137-001. She has young blue stars hanging in the tail.

The disco-like cosmic tentacles of the galaxy are made up of a long gas stretching over 260,000 light-years in space. The Jellyfish Galaxy was first seen by the Chandra X-ray Observatory and the Hubble Space Telescope in 2014.

Newly formed stars

ESO 137-001 is a lattice spiral galaxy that is comparatively similar to the size of the Milky Way. It is located in the southern constellation Triangle Australia and is about 220 million light-years from Earth. It's also part of a group of galaxies called Abell 3627.

His long, gaseous tail is full of newborn stars, and scientists especially want to know the secret behind this phenomenon.

According to NASA, the young stars formed in the tail of the galaxy must be virtually impossible, as the processes that occur in large groups of galaxies must make it difficult for new stars to appear.

The areas between the galaxies are filled with hot gas. This gas acts as a counter wind when it comes from galaxies living in the cluster, which is what is called the process of stripping.

Removing barrier pressure slows the formation of stars in the affected galaxies, so scientists are curious about the star formations in the tail of ESO 137-001. The stripping process had to heat the gas, but surprisingly it did not.

"We find it difficult to remove a molecular cloud that already forms stars, because it must be tightly connected to the galaxy by gravity. again so that it can condense and form stars Stacy Alberts of the University of Arizona, co-investigator of the project.

"Telling these two scenarios is one of the things we want to achieve," she added.

James Webb Space Telescope

James Webb Space Telescope is the key to understanding ESO 137-001. It is scheduled to begin in 2021.

According to NASA, James Webb's telescope will determine the stars' target locations in different areas around the tail: close to its end, in the middle and near the galaxy.

This will help scientists learn how the stripping process evolved over time and its impact on new star formation conditions.

Webb has a special tool installed to further study the mysterious galaxy called the Mid-Infrared Tool. The observations of MIRI will provide 50 times greater spatial detail and 20 times better spectral detail than the previous work of other infrared observatories.

In addition to solving the mysteries of ESO 137-001, the telescope is also capable of exploring the mysterious structures and origins of the universe as well as looking beyond the distant worlds around other stars.

The whole project is possible through the cooperation of NASA, the Canadian Space Agency and the European Space Agency.
