Galaxy: NGC 4603 — all the glory of the star cluster through the eyes of the Hubble telescope»
It is not necessary to pass by and not notice the achievements of an old orbital telescope, Hubble, although an outdated technique for studying distant space, but even it is many times cooler than a conventional ground-based medium-sized telescope. Not every country in the world has something like this, although it is quite outdated. Even Russia can not yet boast of something like this, the observatory in the Crimea or the Pulkovo Observatory only dream of such capacities:)
And so, once again, the "grandfather telescope" pleased the scientific community with photos of a star cluster that is located at a distance of 107 million light-years from the Earth observer. The picture was very clear. Although the object of photography is very much at a decent distance. This time the spiral galaxy NGC 4603 was photographed. This is a rather impressive cluster of stars, which is located in the night sky in the direction of the constellation Centauri.
The galaxy is quite easy to find and if you do not have a large telescope, then it will not be difficult for you, because having a largely weaker telescope in 1834, on July 8, the astronomer Herschel first saw and described it, so you can also do it if you want of course:).
You can read about this amazing object in different catalogs, it is described almost the same everywhere, scientists have not sucked anything new out of their fingers, no one has ever seen the object up close, so look for this amazing galaxy in the catalogs under different names, such names are more common - ESO 322-52, IRAS 12382-4042 and LEDA 42510. The galaxy NGC 4603 is approximately 110,000 light-years in diameter, which is almost the same size as our Milky Way galaxy. This galaxy is part of a group of galaxies called the "Centauri Cluster", in this group, according to scientists, more than 100 medium-and large-sized galaxies have found a place.
The galaxy NGC 4603 has arms, but they are not too pronounced, that is, not very twisted. There are many bright blue stars in the sleeves, they do not live long, but they shine very brightly and disperse both gas and stardust around them, remaining in fact in a clean, cleaned space. These stars in the sleeves form whole lines, they are clearly visible in the photo from the Hubble telescope. There are also red-brown lines in the arms of the galaxy NGC 4603, which are nothing but ordinary dust and gases.
After searching the web, I managed to find a great many photos of the galaxy NGC 4603, apparently it was photographed more than once and not from one point, the photos are all different both in quality and in exposure. Recently, this object is being watched more closely, someone suggested that scientists look for a new class of stars in this galaxy. They search and search, but so far there is no result, although the photos of the galaxy NGC 4603 are getting better and better. I want to find stars that are also called beacons of the universe, they are very constant in the spectrum and are usually called cepheids. Cepheids flicker with amazing regularity, and the frequency is so stable that many parameters can be calculated from these stars with minimal error. It is important to know that such stability allows you to very accurately calculate the distance to a star, and if such a star is in the arm of a galaxy, then you can very accurately calculate the distance to the galaxy itself.
Knowing for example the fact that to some of the Cepheids at a given time a certain distance, and measuring it in the near future, you can be pleasantly surprised, because it will clearly turn out that it has increased.. This is not a deception or an error, it is probably a paradox of the expanding Universe and nothing more. Look at the galaxy NGC 4603, it is very picturesque about what an old telescope like Hubble can see in the depths of space.
