Movie shows Ceres at opposition from sun

NASA's Dawn spacecraft successfully observed Ceres at opposition on April 29, taking images from a position exactly between the sun and Ceres' surface. Mission specialists had carefully maneuvered Dawn into a special orbit ...

Space telescopes pinpoint elusive brown dwarf

In a first-of-its-kind collaboration, NASA's Spitzer and Swift space telescopes joined forces to observe a microlensing event, when a distant star brightens due to the gravitational field of at least one foreground cosmic ...

Kepler gets the 'big picture' of comet 67P

On Sept. 30, the European Space Agency concluded its Rosetta mission and the study of comet 67P/Churyumov–Gerasimenko. During the final month of the mission, NASA's planet-hunting Kepler spacecraft had a unique opportunity ...

Robot would assemble modular telescope—in space

Enhancing astronomers' ability to peer ever more deeply into the cosmos may hinge on developing larger space-based telescopes. A new concept in space telescope design makes use of a modular structure and an assembly robot ...

Light echoes give clues to planet nursery around star

Imagine you want to measure the size of a room, but it's completely dark. If you shout, you can tell if the space you're in is relatively big or small, depending on how long it takes to hear the echo after it bounces off ...

Earth-Space telescope system produces hot surprise
