SUNSET: 
A Great S&T Trip to Iceland
A group of 90 people from around the U.S. and the world joined S&T in early April for an aurora adventure in Iceland.
We Are the Astronomers Who Say NEAF!
The Northeast Astronomy Forum in Suffern, NY, welcomed visitors from across the United States on April 20-21, 2013.
How to Build a Galaxy
The iconic disk galaxy is perhaps the most common type of galaxy in the universe. But how did these galaxies form their wide, thin skirts and fat, round centers?
November's Very Special Eclipse
If you're thinking about joining Sky & Telescope and Spears Travel to see November 3rd's total eclipse of the Sun, here are three important numbers to consider: 29, 12, and 1.002.
A Tumbling Apophis: Good News for Earth
Careful observations of asteroid 99942 last January show it to be both elongated and tumbling — which is good news to the celestial dynamicists trying to predict this body's future close brushes with Earth.
April 25th's Partial Lunar Eclipse
Truly dedicated eclipse-watchers — who live in the Eastern Hemisphere — have a chance to watch the Moon barely graze Earth's umbra during the first eclipse of 2013.
Almost Earth-like Exoplanets
NASA’s Kepler mission has discovered a 5-planet system that includes a hot Mars and four super-Earths, two of which might host liquid water. These aren’t quite the Earth-like exoplanets Kepler’s been looking for, but they’re close.
Come to NEAF April 20-21
Make plans to attend the largest annual astronomy trade show in America: the Northeast Astronomy Forum & Telescope Show.
When Supergiants Explode
Astronomers have announced a new class of gamma-ray bursts, possibly created when some of the biggest stars in the universe go supernova.
Homing in on Dark Matter
Three potential detections from deep underground could be from dark matter particles. While still uncertain, the result suggests a particle mass in keeping with hints from several other experiments.
The Most Distant Star Ever Seen?
Astronomers have detected what might be the farthest star ever spectroscopically observed. The bright object blazes in an unusual location, too, perhaps giving insight into star formation in unconventional environments.
This Weekend's Twilight Sky Gathering
The Moon, Jupiter, Aldebaran, and two naked-eye star clusters adorn the western twilight this weekend, April 12–14. Spread the word, and grab your camera.
Has the Mars 3 Lander Been Found?
New images from the Mars Reconnaissance Orbiter appear to show the Soviet Union's Mars 3 lander, which mysteriously fell silent just seconds after reaching the Red Planet's surface in 1971.
NASA to Snag a Near-Earth Asteroid
Not content to let private companies have all the fun in asteroid exploration and exploitation, NASA managers have proposed a high-flying mission that would capture a small asteroid and dispatch astronauts to study it — all within the next decade.
A New Type of Supernova
Astronomers have discovered a new supernova class where the star might survive the explosion.
Aging Telescope Finds Baby Stars
The Herschel Space Telescope, now approaching its final days, has helped astronomers spot one of the earliest stages of star formation.
Celebrate the Night — This Week, This Month
Anytime is a good time for a star party, but April offers some of the best opportunities to get out under the night's beauty. Take your pick: there's Globe at Night, International Dark-Sky Week, Astronomy Day, and Global Astronomy Month.
Black Hole Wakes for a Light Snack
Astronomers might have glimpsed a supermassive black hole snacking on a brown dwarf in a galaxy 47 million light-years away.
The Oldest, Loneliest Supernova
A distant explosion of a white dwarf, the oldest of its kind, may help reveal the cause of death for other, closer dwarfs.
Possible Dark Matter Signal?
Scientists using an instrument aboard the International Space Station have measured a signal that might come from dark matter — or might not.
