Context: 

  • Researchers have for the first time analysed data of “carbon dioxide auroras” taken from space.

About Aurora:

  • An aurora is a natural phenomenon which is characterised by a display of a natural-coloured (green, red, yellow or white) light in the sky. 
  • Formation: It is a light show which is caused when electrically-charged particles from the sun collide with particles from gases such as oxygen and nitrogen present in the Earth’s atmosphere.
  • Aurora is sometimes referred to as ‘polar light’. 
  • It is predominantly seen in the regions of high altitudes like the Arctic and Antarctic.
  • Auroras are seen in latitudes of around 70 degrees. They generally occur in a band known as ‘auroral zone’.
  • Auroras that occur in the Northern hemisphere are known as aurora borealis and auroras that take place in the Southern hemisphere are known as aurora australis.
  • Auroras can appear in various forms like streamers, patches, arcs, scattered light, diffused light etc.
