The astrophysicists from the Minnesota Institute for Astrophysics have recently discovered the first blow away galaxy.


  • The galaxy was discovered using the “Gemini Telescope”.
  • The galaxy has been named Pox 186.
  • A new study led by the University of Minnesota astrophysicists shows that high-energy light from small galaxies may have played a key role in the early evolution of the Universe.
  • The research gives insight into how the Universe became reionized, a problem that astronomers have been trying to solve for years.
  • The research is published in The Astrophysical Journal, a peer-reviewed scientific journal of astrophysics and astronomy.

Puzzzle solved by blow away galaxy:

  • The Universe was in an ionised state when it was formed after the Big Bang.
  • In this state, the electrons and protons moved freely and combined to form atoms and the water vapor condensed into clouds.
  • The scientists have observed that the Universe is back in its ionised state.
  • Till now, the scientists were unable to find out how this happened.
  • The discovery of blow away galaxy has solved this.

About Blow Away Galaxy

  • According to the scientists, the energy for reionisation must come from the galaxies themselves.
  • However, it is hard for the light energy to escape a galaxy as the hydrogen clouds absorb the light.
  • This is almost similar to that of the earth atmosphere absorbing sunlight.

Note: The Blow away state means that the hydrogen clouds have been removed. This allows light to escape.

  • The Blow away state may be was caused by dying stars, super novas.

Blow Away Galaxy in simple Terms:

  • The star formation is similar to that of blowing a balloon.
  • If the star formation was intense, then there will be a rupture or hole made in the surface of the balloon.
  • This happens to let out some energy.
  • However, in case of Blow Away Galaxy, the star formation was so powerful that the balloon was torn into pieces.

Gemini Telescope

  • It is an astronomical observatory that consists of two telescopes namely Gemini North and Gemini South.
  • They are located in Hawaii and Chile respectively.
  • These telescopes are the largest and most advanced optical telescopes available to astronomers.
