Searching for Earth-like planets: Newly spotted frozen world orbits in a binary star system
A newly discovered planet in a binary star system located 3,000 light-years from Earth is expanding astronomers' notions of where Earth-like—and even potentially habitable—planets can form, and how to ...
Because you can't eat just one: Star will swallow two planets
(Phys.org) —Two worlds orbiting a distant star are about to become a snack of cosmic proportions. Astronomers announced today that the planets Kepler-56b and Kepler-56c will be swallowed by their star in ...
Cassini spies the ice-giant planet Uranus
(Phys.org) —NASA's Cassini spacecraft has captured its first-ever image of the pale blue ice-giant planet Uranus in the distance beyond Saturn's rings.
Faraway moon or faint star? Possible exomoon found
(Phys.org) —Titan, Europa, Io and Phobos are just a few members of our solar system's pantheon of moons. Are there are other moons out there, orbiting planets beyond our sun?
The Drake Equation revisited: An interview with Sara Seager
Planet hunters keep finding distant worlds that bear a resemblance to Earth. Some of the thousands of exoplanet candidates discovered to date have similar sizes or temperatures. Others possess rocky surfaces ...
A brighter method to determine surface gravity of distant stars
Astronomers have found a clever new way to slice and dice the flickering light from a distant star in a way that reveals the strength of gravity at its surface.
Explainer: Light-years and units for the stars
"Space is Big. Really Big." The Hitchhiker's Guide to the Galaxy pretty much nailed space with those five words. And space is so really big that our earthly measures of distance struggle.
Kepler spacecraft's breakdown changes NASA mission's course
Crippled in space, the Kepler spacecraft's planet-hunting days are likely over. But its discoveries may be yet to come.
NOAO: A Kepler's Dozen: Thirteen Stories about Distant Worlds that Really Exist
For centuries, humans have pondered what life on other planets beyond our solar system might be like. With the launch of the Kepler Spacecraft in 2009 we now have evidence for the widespread existence of ...
Astronomers conduct first remote reconnaissance of another solar system
Researchers have conducted a remote reconnaissance of a distant solar system with a new telescope imaging system that sifts through the blinding light of stars. Using a suite of high-tech instrumentation ...
Astronomers suggest new telescopes could detect biomarker gasses in exoplanet atmospheres
Exocomets may be as common as exoplanets
(Phys.org)—Comets trailing wispy tails across the night sky are a beautiful byproduct of our solar system's formation, icy leftovers from 4.6 billion years ago when the planets coalesced from rocky rubble.
Study: At least one in six stars has an Earth-sized planet
(Phys.org)—The quest for a twin Earth is heating up. Using NASA's Kepler spacecraft, astronomers are beginning to find Earth-sized planets orbiting distant stars. A new analysis of Kepler data shows that ...
Astrophysicists find wide binary stars wreak havoc in planetary systems
An international team of astrophysicists has shown that planetary systems with very distant binary stars are particularly susceptible to violent disruptions, more so than if they had stellar companions with ...
