New class of stellar system called 'blue blobs' found: Research
According to the researchers at University of Arizona, a new class of stellar systems has been identified- they’re not quite galaxies and only exist in isolation.
About the new class of stellar systems
- The new stellar systems appear as "blue blobs" through a telescope.
- They are about the size of tiny dwarf galaxies.
- The new stellar systems contain only young, blue stars, and are about the size of tiny dwarf galaxies.
- The blue stars are distributed in an irregular pattern and seem to exist in surprising isolation from any potential parent galaxy.
Where are the Stellar Systems Located?
- The stellar systems are located within the relatively nearby Virgo galaxy cluster.
- It is challenging to identify the origins of the five systems because they are separated from any potential parent galaxies by over 300,000 light years in some cases.
- The fact that the new stellar systems are abundant in metals hints at how they might have formed.
Difference between Stars Born Red and Blue Stars
- Stars that are born red are lower mass and therefore live longer than blue stars, which burn fast and die young.
- Therefore, old red stars are usually the last ones left living. The blue stars are dead because they do not have any more gas with which to form new stars.
- The blue stars are like an oasis in the desert.
Verifying, please be patient.
