PEARLSDG does not have the typical properties of a dwarf galaxy that one would expect.
A team of astronomers has discovered a dwarf galaxy that appears in images from the James Webb Space Telescope. Phys.org reported it.
According to researchers, the newly discovered dwarf galaxy, called PEARLSDG, was spotted in a zone of space where it was not expected to be seen.
This is because PEARLSDG does not have the typical properties of a dwarf galaxy that one would expect to see. It does not interact with nearby galaxies, but does not form new stars. It turns out that this is an interesting case of an isolated galaxy at rest.
“These types of isolated dwarf galaxies have not been seen before, except in a few cases. The fact that we can see this object helps us refine our theories about how they formed,” said Arizona State University research scientist Tim Carlton.
Recent observations of dwarf galaxies have revealed a large number of “ultradiffuse galaxies” (a type of galaxy with low surface brightness and faint edges) that were not available in previous large spectroscopic surveys. This discovery suggests that the understanding of the number of dwarf galaxies may be incomplete.
Another surprise is that some of the stars of the galaxy can be seen in the pictures. The brightness of these stars allows astronomers to measure the distance to it – 98 million light years.
It was previously reported that Hubble detected a cosmic “tug of war” between galaxies, which could lead to their merger.
