Researchers from the Center for Astrophysics (CfA) Harvard & Smithsonian have recently generated a 3D magnetic map of the cavity called Local Bubble.

 

What is a ‘local bubble’?

  • The Local Bubble is a 1,000-light-year-wide cavity or a super bubble. Which exist in the Milky Way.
  • It is thought to have originated from supernovae roughly 14 million years ago.

 

What is a supernova?

  • It is a class of violently exploding stars whose luminosity after eruption suddenly increases many millions of times its normal level.
  • Supernovae explosions release tremendous amounts of radio waves and X-rays and also cosmic rays.
