SUNSET: 
“Coronal Cells” in Sun’s Atmosphere
Astronomers have discovered an unexpected new feature on the Sun, leading to further insights about the solar magnetic field.
Venus Befriends Crescent Moon
The crescent Moon lies close to crescent Venus just after twilight tonight, a great target for a good pair of binoculars.
New Eye for Giant Russian Telescope
From 1975 until 1993, Russians astronomers could boast about having the world's largest optical telescope. Now they're hoping to extend the 6-meter scope's cosmic reach by completely refurbishing its original primary mirror.
Nova (Nova Sagittarii 2012) Erupts in Sagittarius
Observers have reported a "new star," now visible in the predawn sky, that can be seen in small telescopes or good binoculars.
Come to NEAF April 28-29
Make plans to attend the largest annual astronomy trade show in America: the Northeast Astronomy Forum & Telescope Show.
Cosmic Ray Origin Still Mysterious
Observations out of Antarctica support the idea that the most energetic of the superspeedy space particles raining down on Earth are not from gamma-ray bursts. The new result prolongs a long-standing mystery in astrophysics.
A Good Year for Lyrid Meteors
If you've never tried to observe late April's Lyrid meteor shower, this might be the year to try — thanks to moonless skies and a peak that favors North America.
Hubble Celebrates as Shuttle Retires
Hubble is beginning celebrations early for its 22nd birthday with this composite image, a fantastic combination of ground- and space-based observations of the Tarantula Nebula.
Tour June's Sky! | April 17th, 2012
Mars and Saturn are the two bright planets in the evening sky. They're joined by a host of springtime sparklers, including Arcturus (overhead at dusk) and Vega. This month also features the long-awaited transit of Venus and a partial lunar eclipse.
Watch April 16th's Solar Flare!
The Sun erupted yesterday in a magnificent display, and more might be on its way.
WISE Identifies Mystery Sources
Astronomers are using infrared observations from NASA's WISE spacecraft to identify sources seen at energies a million times greater. The work may help astronomers figure out whether they've detected unknown cosmic phenomena.
Tour May's Sky! | April 15th, 2012
Follow the giant arc of bright planets that leads eastward from the just-set Sun: Venus low in the west, Mars midway up in the south, and Saturn over in the east. Then look overhead for the Big Dipper — the "Swiss Army knife" of the night sky.
Titanic's Celestial Connections
The ill-fated ship — and the movie of the same name — were influenced by the heavens in a number of ways.
International Dark Sky Week
Light pollution affects more than just astronomy. Learn what you can do to save energy and baby sea turtles — and keep our skies dark.
Dark Energy BOSSes Around the Universe
Astronomers are honing in on the nature of dark energy, a mysterious, repulsive energy that pervades all of space. Among the questions they're trying to answer: does dark energy exist?
Comet Pan-STARRS: Still on Track
The inbound comet C/2011 L4, discovered last year, has been brightening steadily the past few months. It could still fizzle — or it could become a pretty bauble in post-sunset skies next March.
Far-out Black Hole Hints
“Star cities” orbiting galaxies may reveal the mass of the gargantuan black hole hidden deep in the galaxy’s heart. The new relation could be more evidence for a large-scale black hole-galaxy link — or, it could mean one of the latest revolutions in astrophysics isn’t the full story.
Honoring Titanic's 100th Anniversary
In honor of Titanic's 100th anniversary, read S&T's article from the April 2012 issue about the moon's role in sinking the unsinkable ship.
New ALMA Images Stoke Exoplanet Flame
Astronomers have released the first new science results from the Atacama Large Millimeter/submillimeter Array (ALMA), a still-under-construction network of 66 antennas in northern Chile. The new observations suggest the contentious Fomalhaut star system may have two small planets shepherding its gigantic ring.
Sky & Telescope's New Moon Globe
The year-long effort was time consuming and tedious, but S&T's staff is proud to unveil the first wholly new globe of the lunar surface in more than four decades.
