On the territory of the northern constellation Veronica's Hair resides an amazing cluster of the same name - a structure of over a thousand galaxies connected by gravity. Many of them belong to the elliptical type, such as bright and dominant in the NGC 4860 image (center). But on the outskirts of the cluster can also be seen young spiral galaxies, showing excellent spiral arms. For example, on the left is NGC 4858.
NGC 4858 can be considered a special galaxy. This is not just a spiral, but a “galactic aggregate,” that is, the central galaxy, surrounded by several luminous nodes of material that seem to flow out of it, expand and open. Due to this, the visible structure changes. Also in the vastness of the galaxy there is a high level of stellar birth, which could be activated due to an early collision with another galaxy. We see NGC 4858 diligently forming stars, continuing to expend its own gas until it dries out. The light from the bright nodes indicates that they are made from hydrogen, glowing in various shades of bright red. The image is captured by the powerful HFC camera of the WFC3 space telescope.
