Six incredible pictures of galaxies



As part of the New Year’s celebrations, the NASA / ESA Hubble Space Telescope has unveiled six different galaxy combinations. These rare astronomical phenomena were captured as part of a recent survey to investigate the speed of new star formations.

As part of the release, NASA / ESA explains that these rare merging events will cause galaxies to undergo major changes in their stellar appearance and content.

“These systems are excellent laboratories for observing the formation of star clusters under extreme physical conditions,” the organization wrote. The Milky Way galaxy typically forms clusters 10,000 times larger than our Sun. This is not the same as the mass of star clusters in the galaxy ision, which can reach millions of times the mass of our Sun.

This week’s galaxy from Hubble has a particularly provocative name: the merger of Medusa, about 130 million light-years from B, in the Big Dipper galaxy.
The system consists of IC 694 and NGC 3690, a pair of galaxies that passed about 700 million years ago. As a result of this interaction, the system underwent a massive explosion of stars. Over the past 15 years or so, six supernovae have appeared outside the galaxy, making this system a unique supernova factory.

These events shed great light, and even after the ision, when the galaxy system, which is its antecedent, falls into a state of calm, the massive star clusters continue to glow brightly.

This image shows a strange galaxy called NGC3256. The galaxy is about 100 million light-years from Earth, and its distorted appearance is the result of a previous galaxy merger. Therefore, NGC 3256 provides an ideal target for the investigation of stellar explosions caused by galaxy fusion.

These photos are a selection of six of the 59th set published between early 2008 and October 2020.

The galaxy system NGC1614 has a bright optical center and two clearly symmetrical inner spiral arms.
NGC 6052 is located 230 million light-years away in the constellation Hercules and is a pair of colliding galaxies.

“After studying the six galaxy combinations described here, the Hubble Imaging Survey (HIPEC) investigated how Hubble Imaging Survey (HPEC) could affect how star clusters are affected by rapid changes in these galaxies that greatly increase the speed of new star formation.

“Hubble’s capabilities have enabled us to solve the big star formation knot into many more compact young star clusters. Hubble’s observations of ultraviolet and near-infrared light from these systems have been used to analyze stellar age, mass, and extinction, and the rate of star formation in these six galaxies. The HPEC study reveals that star clusters undergo large and rapid changes. Their properties, at the end of the fusion phase, form massive clusters.

NGC 34 is located in the constellation Catas. The outer zone of the galaxy is translucent and has strangely smooth stars and orbits.
