Astronomers have found the first Earth-sized exoplanet within a star's habitable zone. The planet is the closest thing yet to the coveted 'Goldilocks' orb that scientists have long sought — a world roughly the size of Earth orbiting a star at a distance that is just right for liquid water to exist.

"We definitely think it's one step closer to finding a true Sun–Earth analogue," says study co-author Elisa Quintana, an astronomer at the SETI Institute in Mountain View, California, and at the nearby NASA Ames Research Center in Moffett Field. But because the star that the exoplanet orbits is a cool, dim one unlike the Sun, Quintana and her colleagues consider the planet more of a cousin to Earth than a twin.

From Laughing Squid:

Astronomers have discovered what may be a Thorne–Zytkow object (TZO), a binary star system where a neutron star is enveloped by a red giant or supergiant star. TZO's were first theorised in 1977 by Kip Thorne and Anna Zytkow. On June 4th, 2014 a team of astronomers led by Emily Levesque that included Zytkow published a paper identifying red supergiant star HV 2112 in the Small Magellanic Cloud as a possible TZO candidate.

This cylindrical projection global map is one of six new color maps of Saturn's midsized icy moons, constructed using 10 years of image data from the Cassini spacecraft. Discovered by Cassini (the astronomer) in 1684, Dione is about 1,120 kilometers across. Based on data extending from infrared to ultraviolet, the full resolution of this latest space-age map is 250 meters per pixel.
