Andromeda galaxy as never before

NASA astronomers and the University of Washington unveiled it. It is the most detailed panoramic view of the Andromeda Galaxy created by the Hubble Space Telescope. The 417 megapixel image includes more than 200 million stars. It is just a fraction of the billion stars that are calculated in the galaxy. Thanks to this, we see the Andromeda galaxy as never before.

The photomosaic took more than 10 years to create and required more than 1,000 orbital revolutions of the Hubble. He took 600 snapshots different from the galaxy. Andromeda is convenient for observations from Earth to be at an angle of 77 °. It is the nearest spiral galaxy, 2.5 million years-old from the Milky Way.

Now we see the Andromeda galaxy as never before.

Millions of stars

In Hubble images about 200 million stars can be detected. It shows the Andromeda galaxy as never before. That is just a fraction of Andromeda’s stars and many of them brighter than our sun. The last of the polls that completed the panoramic image of Andromeda added information about the southern edge of the galactic disc of said galaxy.

The analysis of the stellar clusters have shown that Andromeda has suffered important collisions with other galaxies. One of the alleged guilty It could be the Compact Satellite Galaxy Messier 32. «Andromeda is a trains clash. It seems as if it had gone through some kind of event that made him form a lot of stars and then simply went out. It was pointed out by the study co -author of the University of California, Daniel Weisz.

This galaxy is the most visible to us, outside the Milky Way.

Expanding images

Andromeda and the Milky Way, despite being approximately the same age, they have very different evolutionary stories. Andromeda seems to be more populated with young stars and unusual characteristics, such as stars -consistent currents. This indicates a recent history of stellar training and interactions more active than that of the Milky Way.

“This will help us to rebuild the history of the mergers and interactions of the galaxy.” Phast’s principal researcher, Ben Williams said.

The new Hubble data will serve as a basis for future observations of the James Webb space telescope. And also of the Nancy Grace Roman space telescope, which will be launched soon. The latter is essentially a great angle version of the Hubble. You can capture the equivalent of at least 100 highly detailed images of the first in a single exhibition.
