Dear MEL Topic Readers,
Alien life in Universe: Scientists say finding it is 'only a matter of
time'
Are we alone in the universe? Most of us think there may be someone, somewhere.
Although there was no evidence of planets orbiting other stars three decades
ago, over 5,000 exoplanets have been discovered and studied since then. 59 of
them are orbiting in the habitable zone, or Goldilocks zone where it is not too
cold or hot liquid water for water to exist on the surface of a planet or moon.
How do scientists and astronomers find and study distant planets that are light
years away? (Note: one light year is 9.5 trillion kilometers) Also, they are
studying the habitability within our solar system. Europa, one of the moons
orbiting Jupiter, and Enceladus, a moon of Saturn, are thought to have liquid
water even though they are out of the habitable zone. In the early 2030s, space
probes are scheduled to arrive at Europa to examine the icy moon. Will we ever find
signs or evidence of aliens on distant planets in the near future?
Enjoy reading the article and learning about technologies and projects in
search of alien life.
