A new galaxy discovered by scientists who managed to take amazing pictures.

the Galaxies are groups of starsAnd masses, dust and gas are held together by their own gravitational force. The name comes from the Greek word γαλαξίας (galaxas), which means “milk, milky”. The reference is clearly to the galaxy in which the solar system falls, i.e. the Milky Way.

the Galaxies can be of different sizeswe go from the so-called dwarf galaxies, which contain only a few hundred million stars, to the giant galaxies, which can contain hundreds of millions of stars.

Over time, scientists have classified known galaxies according to their shape, which can be of three types: Elliptical, spiral or irregular. Other differences occur based on the color which can vary depending on the lengthwave of the electromagnetic spectrum.

But how many galaxies are there in the universe? It is impossible to prove this with certainty, even if scientists make some estimates. What we do know is that there are definitely more than 2 trillion galaxies in the visible universe. Of these, besides the Milky Way, there are only three that can be observed with the naked eye: the Large and Small Magellanic Clouds, visible only from the Southern Hemisphere, and the Andromeda Galaxy, observable from the Northern Hemisphere.

The new galaxy discovered by scientists

Scientists are constantly scanning the sky to try to spot new galaxies and, at the same time, understand how they evolve over time. Monitoring is done through Very powerful space telescopes Like theHubble It is operated by the space agencies NASA and ESA. Recently thanks to Hubble, scientists have discovered a new star cluster deep in the universe.

which is called Jellyfish galaxy Because they are surrounded by what appear to be luminous tentacles that spread across the darkness of the universe. This galaxy was given a name JO201 It is located in constellation piscesalso known as Cetus, is so large that it can be seen without problems from both the southern and northern hemispheres.

monitoring JO201Scientists hope to learn more about jellyfish galaxies and the phenomenon of “stripping,” the process that leads to gas being released. The enthusiasm is explained by the special sharpness of the photos collected by wide field camera 3 (WFTC3), with which the Hubble telescope is equipped. It is this particular camera that has allowed the most amazing shots in the universe, as it is able to capture ultraviolet wavelengths, not just infrared and invisible.
