This artist’s impression shows the planet Proxima b orbiting the red dwarf star Proxima Centauri, the closest star to the Solar System. The double star Alpha Centauri AB also appears in the image between the planet and Proxima itself. Proxima b is a little more massive than the Earth and orbits in the habitable zone around Proxima Centauri, where the temperature is suitable for liquid water to exist on its surface.

Earth-Like Planet Discovered In Habitable Zone Of Nearest Star

Amazing news! Today, a team of European astronomers announced the discovery of a potentially habitable planet around Proxima Centauri, the nearest star beyond the sun. That planet, called Proxima b, is at least 1.3 times the mass of Earth and squarely located within the star’s habitable zone, where temperatures are clement enough for liquid water…

Full Sturgeon Moon Part Two

Did you see that big moon last night? August is the time of the Full Sturgeon Moon, named for the best time to catch sturgeon in the Great Lakes. Because the moment of lunar fullness occurred this morning at 4:26 a.m., we get a full moon “spillover effect” or two nights in a row of…
