Astronomers announced Tuesday that they have found eight new planets in the Goldilocks Zone of their stars, orbiting at a distance where liquid water can exist on the planet's surface. The discoveries double the number of small planets believed to be in the habitable zone of their parent stars.
Harvard researchers have found that stars slow down as they age, and their ages are well-kept secrets. But astronomers are taking advantage of the first fact to tackle the second and tease out stellar ages.
For life as we know it to develop on other planets, those planets would need liquid water, or oceans. Geologic evidence suggests that Earth’s oceans have existed for nearly the entire history of our world.
Despite a malfunction that ended its primary mission in May 2013, the Kepler spacecraft is alive and working. The evidence comes from the discovery of a new super-Earth using data collected during Kepler’s “second life.”

The quest for a twin Earth is heating up. Francois Fressin, of the Harvard-Smithsonian Center for Astrophysics (CfA), presented the new analysis of Kepler data that shows that about 17 percent of stars have an Earth-sized planet in an orbit closer than Mercury.
CfA fellow David Kipping is heading a hunt for astronomical bodies at the edge of our ability to detect them: moons circling planets in other solar systems.
Using a continent-spanning telescope, an international team of astronomers has peered to the edge of a black hole at the center of a distant galaxy. For the first time, they have measured the black hole's "point of no return" — the closest distance that matter can approach before being irretrievably pulled into the black hole.
At first glance, the center of the Milky Way seems like a very inhospitable place to try to form a planet. New research by astronomers at the Harvard-Smithsonian Center for Astrophysics shows that planets still can form in this cosmic maelstrom.
Alex Parker, a postdoctoral fellow at the Harvard-Smithsonian Center for Astrophysics, sees astronomical data as art as well as science.
