Bailey Universe - The Hubble Telescope amazes us again with a fabulous image, of course, captured by him. The Hubble Telescope captured a nebula, called the N44 on November 2, 2021, in an extraordinary position. Hubble's Surprised Nebula (N44) is a complex nebula filled with glowing hydrogen gas, dark dust bands, massive stars, and many star populations of various ages, according to NASA. This image is the most recent image captured by Hubble with a Nebula. 

Hubble caught her in a very good position, because that's how we can see the gap in her middle, which is called "superbula". That void is simply a hole in the nebula through which everything behind the nebula can be seen. As you can see, this gap is very small in the image, but it is not so in reality. The Hubble Telescope surprised this nebula from an extremely long distance, so the hole is much larger than seen in the picture. According to NASA, the hole is 250 light-years wide! Because it is so large, its appearance is still a mystery. 

Many hypotheses say that something very big could have receded through that nebula or maybe that's just how the nebula formed. However, its exact existence is not known. However, the hypotheses brought by NASA are much more credible. The space agency claims that first of all there are many stars near that nebula as you can see. Because are there many stars, can form stellar winds, which are expelled from massive stars that are inside the fog, could eventually drive away the gas. But what is wrong with this hypothesis is that the measured wind speeds in the nebula would be a contradiction. 

NASA's second hypothesis, harder to understand if you don't know some astronomical or astrophysical terms, is that the fact that there are many massive stars inside the nebula, it by powerful explosions, the expanding shells of ancient supernovae to carve the cosmic cavern, NASA claims. Also, so far we know that astronomers have discovered an old supernova near the superbula, between them being a difference of 5 million years (between the stars inside and at the edge of the superb). Through them many stars were formed in a chain reaction. 

Also in the image, you can see a lot of blue in the nebula, almost all in the nebula. That blue is one of the hottest parts of the fog. Hubble saw it, probably from a very hot side. Also, because it is perhaps even the hottest part, stars are formed there. As we can see around the nebula, quite a few stars have formed. But, let's tell you where the nebula is located. The nebula is located at approx. 170,000 light-years on Earth and stretches over 1000 light-years.

How did the nebula form? It is not known 100% how it was formed and all the processes done. But most likely, after several studies, it is said that this nebula was formed by various stellar processes. Because NASA claims that this nebula is an emission nebula, its gas has been either energized or ionized. By whom? by the radiation of nearby stars. And then, how does the nebula start to glow? Scientific data shows that ionized gas descends from a higher state by cooling to a lower state. This process emits energy in the form of light, so the nebula is no longer just a matter, which is not seen from a distance, but is something bright that can be seen.
