NASA has announced the discovery of seven earth-sized planets with conditions that could be right for liquid water and possibly life, according to npr.org.
These seven planets orbit a nearby star called TRAPPIST-1, which is about 39 light-years away. TRAPPIST-1 is about 10 times smaller than the sun and is about the size of Jupiter. It is classified as a ultracool dwarf star, stated mnn.com.
The discovery sets a record for the most earth-sized planets and the most potentially habitable planets. The TRAPPIST-1 star system was discovered by the Spitzer Space Telescope, added mnn.com.
“This discovery could be a significant piece in the puzzle of finding habitable environments, places that are conducive to life,” said Thomas Zurbuchen, associate administrator of NASA’s Science Mission Directorate, according to cnn.com. Three of the planets are located in the “Goldilocks Zone,”also known as the habitable zone which means that they could have liquid water on it’s surface. Although most of the other planets don’t have the right conditions for life.
If you were to stand on one of these planets you could be able to see the others as well as we see the moon. Astronomers could even understand these seven planets even better when the James Webb Space telescope is launched in 2018, according to npr.org.
