Astronomers discover life 31 light years away!

 

Recommended for Preparatory Grades

Astronomers have discovered a planet that is roughly the same size as Earth. The planet also orbits its star at a distance that allows for it to be potentially habitable for life.

This planet is located 31 lightyears away.

What is an extrasolar planet?

A planet that is not part of our Solar System is called an extrasolar planet.

Key facts!

  • A group of astronomers discovered a nearby red dwarf star called Wolf 1069.
  • Wolf 1069b is the name given to the recently discovered extrasolar planet.
  • It is 1.36 times the mass of Earth.
  • Researchers say that they found a clear, low-amplitude signal from what seems to be a planet about the size of Earth.
  • Also, Wolf 1069b only gets about 65% as much radiation from its star as Earth does from the Sun.
  • Astronomers say their computer simulations reveal that 5% of emerging planetary systems surrounding low-mass stars like Wolf 1069 have a single visible planet.
  • The simulations also show that the core of Wolf 1069b is still molten, similar to the core of the Earth.
  • Thus it could be producing a magnetic field as a result.
  • A temperature map that was simulated for Wolf 1069b shows that the region that is directly facing the star is the most likely place to find liquid water.
  • Since Wolf 1069b does not come between us and its star, the researchers aren’t sure whether Wolf 1069b has an atmosphere.
  • Experts are hoping that with advancements in technology, they’ll be able to investigate the further possibility of life on Wolf 1069b.
