The final destiny of this type of galaxies is to end up losing one of their great abilities.
The Solar System, a small corner of the universe where we live, is located inside a spiral galaxy called the Milky Way. This is the most common type of galaxy in the known cosmos, although there are also elliptical, lenticular, and irregular galaxies. A recent publication on the NASA website, in this case, announces the encounter with a jellyfish galaxya very particular type and that has a curious story behind.

Although in recent times it seems that the role of the James Webb telescope is greater, its older brother Hubble still continues to show us that unknown universe, which nobody can see. According to information from NASA, it has been hubble who has managed to sight the jellyfish galaxy JW39. For two years now, the telescope has been looking at this galaxy, located 900 million light years in the constellation Cabello de Berenice.

The image, impressive as usual in this type of cosmic snapshots, shows us the escape from the galaxy JW39 of a galaxy cluster in which it is immersed. On this occasion, unlike what can happen in an independent galaxy such as the Milky Way, this type of galaxies has to withstand the force of gravity of other larger galaxiescausing their shapes to change.
And that’s not all. besides going changing its shapeand due to the plasma that is between galaxies, the galaxies must fight like a fish swimming against the current, which makes them go moving in a hostile environment and let them go losing gas as gravity and plasma affect them.
In cosmology, the term applied to the processes described above is ‘drag pressure’ and it is what goes generating ramifications at the ends of the galaxy, like jellyfish tentacles, and for which JW39 receives the name of the marine animal. To observe this galaxy, the space telescope hubble has used the Wide Angle Camera 3finding that star formation in JW39’s tentacles was not too different from star formation in the galaxy’s disk.
And as we anticipated at the beginning of the article, the final destination of this type of galaxies is to end up losing its gas, making it impossible for new stars to form inside.
