“Hubble” is watching a spiral galaxy like a cloud in a new image




This image from the NASA/ESA Hubble Space Telescope (Hubble) shows galaxy NGC 4237. Located about 60 million light-years away in the direction of the Veronica Hair constellation, NGC 4237 is a class of flocculent spiral galaxies. This means that it is impossible to clearly distinguish individual spiral sleeves in it, as in galaxies with ordered spiral structure. Instead, there are intermittent spiral sleeves in the galaxy, giving it the appearance of a shallow cloud.

Astronomers studying the NGC 4237 galaxy are actually more interested in its galactic baldge, the bright central region. By studying the structure of the baldge in more detail, we can understand the processes of evolution of spiral galaxies and study the growth of supermassive black holes, which lie in the centers of most spiral galaxies. According to some researchers, there are indications that there is a connection between the mass of a black hole in the center of the galaxy and the mass of its baldj.

However, the nature of this connection is still not fully established, and this is one of the reasons that astronomers study galaxies located in a nearby part of the universe – such as Galaxy NGC 4237.
