This is a site about all things cosmos, Astronomy, Space, Science, Theoretical Science, History, Life. In between you will see a lot of appreciation towards popularizers of science and the cosmos like the late Carl Sagan. I will post music to go along with the vibe of this site, as well as images relating to space and science, Videos, artist impressions. etc. Browse through, there might just be something that will strike a chord.

Gliese 581d: Confirmed as Habitable Exoplanet
After years of saying habitable exoplanets are just around the corner, planet hunters have finally found one. Gliese 581g is the first planet found to lie squarely in its star’s habitable zone, where the conditions are right for liquid water.
“The threshold has now been crossed,” said astronomer R. Paul Butler of the Carnegie Institution of Washington, one of the planet’s discoverers, in a press briefing Sept. 29. “The data says this planet is at the right distance for liquid water, and the right mass to hold on to a substantial atmosphere.” The discovery is both “incremental and monumental,” comments exoplanet expert Sara Seager of MIT, who was not involved in the new study. When a recent study predicted the first habitable world should show up by next May, Seager rightly said the real answer was more like “any day now.” “We’ve found smaller and smaller planets that got closer and closer to the habitable zone,” she said. “But this is the first that’s in the habitable zone.”
