Kepler-186f orbits an M dwarf star in the constellation Cygnus. More importantly, it's the first confirmed Earth-size, potentially habitable planet elsewhere in the universe.

One of them, called KOI 5715.01, has four of the desirable aspects for a superhabitable planet. It’s located in the Cygnus constellation about 3,000 light-years from Earth.

In the most densely packed regions of Cygnus OB2, the researchers found protoplanetary disk possession dropped as low as 1%. That would, therefore, be the worst place for planets to attempt to form.

Kepler-186 and the Solar System: The diagram compares the planets of the inner solar system to Kepler-186, a five-planet system about 500 light-years from Earth in the constellation Cygnus. The ...

July stargazing is certainly a late show, but it’s worth losing some sleep over because it’s now prime time for summer ...

Swarthmore’s Strand picked up the new planet while measuring the orbits of a double star in the constellation Cygnus. He found that in their circlings around each other the two stars deviated ...

NASA’s Kepler space telescope, launched in 2009, detected thousands of planets in a fixed patch of sky near the constellation Cygnus. As the planets passed across the face of their star, they ...

Using NASA's Chandra spacecraft, astronomers have found "danger zones" for worlds where planet-birthing disks are blasted with high-energy radiation from massive young stars and rapidly disintegrate.

The danger to forming planets in densely packed star clusters like Cygnus OB2 comes from high-energy ultraviolet and X-ray radiation blasted out in excess by massive infant stars.This radiation ...
