Star Formation in Dwarf Galaxies
Part of: GS Prelims and GS-III- Space
- Recently, astronomers from the Aryabhatta Research Institute of Observational Sciences (ARIES) have found out the reasons behind intense star formation in some dwarf galaxies.
- Hydrogen in these dwarf galaxies is found to be irregular and sometimes not moving in well-defined orbits (non-symmetric hydrogen distribution).
- Some Hydrogen around these galaxies is also detected in forms of isolated clouds, plumes, and tails
- Scientists used the Devasthal Fast Optical Telescope (DFOT) near Nainital (Uttarakhand) and the Giant Metrewave Radio Telescope (GMRT) in Maharashtra.
Do you know?
- Dwarf galaxies are the most abundant type of galaxy in the universe but are difficult to detect due to their low luminosity, low mass and small size.
