What are monster galaxies?

  • They are thought to be the ancestors of the huge elliptical galaxies in today’s universe and pave the way to understanding the formation and evolution of such galaxies.
  • A unique characteristic of monster galaxies (or starburst galaxies as they are also called) is that they form stars at a startling pace —1,000 times higher than the star formation in our galaxy.
  • On investigating one called COSMOS-AzTEC-1, an international team of astronomers has recently found that clouds throughout the galaxy are very unstable, which is unusual.
  • The gas in COSMOS-AzTEC-1 will be completely consumed in 100 million years, which is 10 times faster than in other star forming galaxies.
