Astronomers discover 7 potentially habitable exoplanets orbiting nearby dwarf star
By AVIANNE TAN 02-22-17
An international team of astronomers has discovered seven potentially habitable exoplanets -- or planets outside our solar system -- that could have liquid water on their surfaces, according to a paper published Wednesday in the journal Nature.
Climate modelling suggests only one of Trappist-1's seven planets is a candidate for life, while other research suggests microbes might be migrating between several of them. Andrew Masterson reports.
At least three of the planets looked like they were within the star’s “habitable zone” – the region in which water will remain liquid. On that level, at least, the trio seemed like very good candidates for hosting life.
Now, however, 3D climate modelling is dampening expectations, suggesting that at most only one of Trappist-1’s satellites could support life.

sherlew99: What a fascinating concept. Well the air above would occupy an area of space. Plus the basic word "space" is just a common term that fails to include the vast, wonderful weirdness out there between all objects out beyond our world.
