India's first mission to the Red Planet launched successfully November 5th from a barrier island off the country's coastline. The mission will study Mars's atmosphere and surface and is an important milestone for the country's space agency.
Tim Puckett has been studying comets and finding supernovae with his home-built telescopes since the 1990s. Now the American Astronomical Society has recognized his dedication with the 2012 Chambliss Amateur Achievement Award.
Beginning later this year, the Hobby-Eberly Telescope Dark Energy Experiment will begin to analyze the spectra of one million primordial galaxies — and, its designers hope, get some answers about the mysterious force that's accelerating the expansion of the universe.
If you are wondering what's in the skies in 2012, Skywatch is just the magazine for you. This video is a preview of this year's issue. Skywatch is now available on newsstands in the U.S. and Canada.
Recent observations of comet Hartley 2 shed light on one of the oldest mysteries: where did Earth's water come from?
Closer observations shed light on the history of Vesta's cratered surface, its mineral composition, and its inner iron core.
NASA's Kepler mission has found an exoplanet that orbits a close pair of stars. This Tatooine-like world should have a lot to tell about planet formation in binary star systems.
Astronomers have discovered a truly weird planet-like object: a former star core apparently make of a superdense form of diamond, orbiting a pulsar with
The Lyman-alpha blobs have been a mystery since their discovery in 2000. Recent research however might offer clues.
The surviving one of NASA's two Mars Exploration Rovers is reaching the brink of a whole new adventure on Mars.
NASA's solar-powered spacecraft Juno successfully lifted off Cape Canaveral on Friday, August 5th.
Recent research suggests that the thick, heavily cratered crust on the Moon's far side could be the pasted-on remains of a second satellite that once orbited the early Earth.
Dawn sends stunning images from Vesta of an uncharted alien world.
Austrian amateur Matthias Kronberger has found a planetary nebula near the northern constellation of Cygnus, the Swan. His discovery might help scientists understand the role of stellar companions in the formation of these glowing gas clouds.
This week, Earth was hit by a barrage of intriguing images of Vesta — all courtesy of Dawn, NASA's latest asteroid orbiter!
NASA's spacecraft Dawn entered orbit around Vesta on July 16th and is preparing for a year's observation of the second-largest body in the asteroid belt.
Sky and Telescope's editor Sean Walker puts together NASA's anniversary images of Neptune to create a movie that shows a day on the blue planet.
Two studies reveal that the white smear across Saturn's northern face was caused by a deep seated thunder storm that discharged powerful lightning bolts for days on end.
By tracking two visible features in Neptune's atmosphere, a University of Arizona astronomer has clocked a new spin rate for the blue planet. But does this mean the Voyager results from 1989 are wrong?
A team of European astronomers has discovered the most distant known quasar.But at its heart is a monstrous black hole that could rob theorists of a few nights' sleep.
Edwin Hubble's tuning-fork diagram has helped astronomers classify galaxies for more than 70 years. But recent research shows that it might be time for a makeover — to a "comb" diagram.
Can hydrogen freeze solid in interstellar clouds? If so, it might contribute to a mysterious form of interstellar light absorption.
In the latest citizen science project, you can help NASA hunt new objects in the Kuiper Belt and perhaps even steer the New Horizons probe toward your lucky find.
Combining data from the deepest images ever taken in visual/infrared wavelengths and X-rays, astronomers have discovered some of the earliest black holes in the universe.
A powerful Gamma Ray Burst captured by the Swift space telescope earlier this year gives astronomers a unique chance to study tidal disruption.
