With how vast the universe is, with billions of stars in each of the trillions of galaxies in it. We may find life on another planet, eventually. It’s only a matter of time until we do find life on another planet.
NASA streamed a live event on February 22 in a press release of a discovery of a lifetime, seven planets orbiting a dwarf star. The solar system in which they discovered is called Trappist-1. Three planets of which are in the habitable zone of the star. Two are a little smaller than our own Earth, and the farthest planet in the zone is slightly larger than that of Earth. About 13% bigger. They all could potentially contain water on their surface. Two planets were first discovered in 2016, then five more were discovered.
Potentially, all of the seven planets could contain water, if they have the right atmospheres. However, the best chances of any of them, are the ones in the habitable zone.
The solar system, Trappist-1, is about 40 light-years (235 trillion miles) from Earth. Making it relatively close to our own solar system.
It is hopeful that in the near future, we will be able to see what the atmospheric pressure is on the three rocky planets.
The first planet (Trappist-1e), is the closest one to the star in the habitable zone. It receives about as much sunlight as the Earth. The second one (Trappist-1f), receives about as much sunlight as Mars. And the third one (Trappist-1g), receives as much light as between Mars and the asteroid belt. (As per what was said in the press release on Wednesday.)
