The Importance of Gliese 581g

submitted by RFlagg

1 decade 3 years 7 months 1 week ago

Tdarnell, who did a couple great videos on the Deep Field Image and the Ultra Deep Field Image among other great vids, talks about Gliese 581g, a near Earth size (3.1 Earth masses) exoplanet found in the magical habitable zone and its importance to science now. It is amazing how much detail they can tell about a planet so far away (20.5 light years). Science rules.
Cut from his YT description:
The fact that we've found a habitable planet candidate so soon after starting our search has important implications for the number of habitable planets that may exist in our galaxy - which was estimated to be around 10 billion.
Having found Gliese 581g so soon though, may mean one of two things. Either we were very lucky, or there are more planets out there than we thought. Based on this discovery, it's possible that we may have meny more habitable planets than originally thought.
Perhaps 20 to 30 billion stars in our galaxy may have conditions suitable for life.
