Here’s what you need to know about a new fundraising venture, the race to name 500,000 craters on Uwingu’s Mars map.
Announcing the winners of Sky & Telescope's Comet ISON photo contest, sponsored by Celestron.
A radioactive element produced near the heart of collapsing stars hints at the mechanism behind Cassiopeia A’s supernova explosion.
Astronomers using a novel technique have mapped a brown dwarf's visible surface — even though they can't resolve the object in telescopes.
A rare alignment of a quasar’s “flashlight” beam and a filament of the cosmic web illuminates the universe’s large-scale structure.
Miniature robots crawling along glass plates will help big surveys collect light from hundreds of thousands of galaxies.
From high-altitude clouds discovered on a super-Earth to massive, hurricane-force storms on a nearby brown dwarf, a bevy of results show that the age of “astrometeorology” is upon us.
Astronomers have found supermassive black holes in 151 dwarf galaxies, surprising expectations and providing a time machine into black hole formation.
The comet's come and gone, we've selected our photo-contest finalists, now it's your turn! Tell us which photos you think should take 1st, 2nd, and 3rd place. The polling booth closes on January 22nd.
Most alien planets are nothing like what we've got in the solar system. Scientists are homing in on these mysterious worlds to see what they’re made of.
Robert Zimmerman writes in the March 2014 issue about the construction of the Giant Magellan Telescope, "demonstrating astronomical engineering of the highest order." The mammoth telescope will combine seven 8.4-meter (28-feet) mirrors into a flower-like primary with the resolving power of a mirro 24.5 meters (80 feet) wide. But the Giant Magellan Telescope isn’t...
The gossamer veil of reflective dust surrounding the star RS Puppis reflects its flickering light in a fantastic display.
Astronomers have come up with a new technique for measuring an alien planet’s mass, and therefore its composition and potential habitability, even when standard methods don’t work.
The "comet of the century" famously lost its battle against the Sun, but you can still enter our photo contest for a chance to win some hefty prizes. Don't miss the December 31st deadline!
Two teams have announced the discovery of water on alien worlds. But they found less water than expected, suggesting these planets are surrounded by a high-altitude haze.
Astronomers have revealed a supposedly monster black hole to be rather ordinary in size.
Observations of one of the most powerful supernovas ever recorded suggest that the standard model for gamma-ray bursts might be missing a piece of the puzzle.
Astronomy is ready for the next generation of detectors, and superconductors are at the heart of the coming revolution.
The January 2014 issue of Sky & Telescope features Yvette Cendes’s article on radio emission from Jupiter — and the possibility that we might soon hear similar radio signals from planets beyond our solar system. Even as astronomers race to catch the radio whispers from a hot Jupiter orbiting another star, NASA’s Radio Jove...
Two recent experiments limit physicists’ favorite candidate for the elusive and invisible matter lurking in the universe.
The red giant star Kepler-56 spins on an axis offset by a bizarre 45 degrees from its transiting planets. The discovery of a third companion could explain why.
Turns out “the lonely star of autumn” has not just one, but two distant companions, making it one of the most widely separated systems known.
The first half of October 2013 is a good chance for early risers to catch the zodiacal light, the faint eastern glow preceding dawn.
