Star Formation in Dwarf Galaxies

Part of: GS Prelims and GS-III- Space

In news

  • Recently, astronomers from the Aryabhatta Research Institute of Observational Sciences (ARIES) have found out the reasons behind intense star formation in some dwarf galaxies.

Key takeaways

  • 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.
