Mars in Feburary 2012

Indian Mars Mission Launches

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

Tim Puckett’s Award-Winning Ambition

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.

Hobby-Eberly Telescope

A Bold Plan to Study Dark Energy

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.

SkyWatch 2012

Skywatch 2012 — A Preview

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.

The Kepler-16 system

A Planet Orbiting Two Suns

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.

Amateur Discovers A Planetary Nebula

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.

Neptune in Motion

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.

In this image, Karkoschka modified the colors and contrasts to emphasize the planet’s atmospheric features.

The Truth About Neptune’s Spin

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?

The Altas 3D team has used the optical images of 260 early-type galaxies in combination with their rotational data to reclassify these as fast and slow rotators.

Rethinking Galaxies

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.

An artist's conception of a supermassive black hole enshrouded in gas and dust rapidly expanding in the clime of the early universe. Scientists recently discovered over 200 such black holes at a red shift of 6 to 8.

The Earliest Black Holes

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.
