Two Moon-Planet Conjunctions Juice Up July
On July 5th, the Moon has a remarkably close brush with Mars, followed two nights later by a similar rendezvous with Saturn.
Super-close Pairing of Ceres and Vesta
Two bright asteroids now appear extremely close to one another in the evening sky. Here's how to spot them in binoculars or a small telescope.
Black Hole Trio Found
Astronomers have discovered that one member of a pair of supermassive black holes is actually a pair itself, turning the system into the most distant black hole triplet yet detected and raising hopes for future discoveries.
Rosetta's Comet Sleeps Again
Comet 67P/Churyumov-Gerasimenko only woke briefly before starting another nap, expected on-again-off-again behavior that bodes well for the comet-chasing spacecraft's arrival in August 2014.
Iapetus Comes Over to the Bright Side
Astronomers now know the secret of this moon's strange two-faced appearance, but it's still remarkable to watch the "now you see it, now you don't" performance as it moves around Saturn.
Govert Schilling Wins AAS's Schramm Award
Sky & Telescope contributing editor Govert Schilling has been selected as the winner of the 2014 David N. Schramm Award.
Titan Sheds Light on Alien Atmospheres
Saturn’s largest moon Titan played a cameo as an exoplanet, allowing astronomers to better understand how a thick layer of haze or clouds might affect their observations of more distant alien worlds.
Shadow of a Supervoid
Scientists might have discovered the source of the mysterious Cold Spot in the Cosmic Microwave Background: an enormous supervoid.
Sea Changes on Saturnian Moon
Fleeting radar features in a sea in Titan’s northern hemisphere are a tantalizing possibility of seasonal changes.
NASA Amassing Targets for Asteroid Mission
Despite skepticism from scientists and politicians alike, NASA is proceeding with its asteroid redirect mission and has found six candidates for exploration so far.
Groundbreaking for Europe's Giant Telescope
The top of Cerro Armazones in Chile yielded on June 19th to a blast that paves the way for the European Extremely Large Telescope.
Summer Quest for Noctilucent Clouds
Noctilucent clouds form at the boundary between Earth and space. Their electric blue billows incite the imagination and inspire us to keep watch at dusk for their arrival.
Hybrid Star Spotted in Small Magellanic Cloud
Since Thorne-Żytkow Objects were proposed forty years ago, no one has actually seen one of these exotic stellar hybrids – until now.
Bill Bradfield, Comet Hunter Extraordinaire (1927-2014)
The prolific comet hunter William A. Bradfield tallied 18 comets in his lifetime, each discovered visually and credited to him alone.
Three New Findings About the Moon
Researchers have announced interesting news concerning the Moon, especially about how and when it formed, and why the "Man in the Moon" constantly stares at us whenever the lunar disk is fully lit.
A MAD New Way to Make Black Hole Jets
Newly published observations provide the first real evidence supporting a theory that tells us how black hole jets form.
Comet PanSTARRS Keeps Getting Better
Since C/2012 K1's discovery two years ago, this first-time visitor from the outer solar system has brightened steadily and is now within reach of a small telescope and even binoculars.
Kepler: Revived and Working Again
NASA’s crippled planet-hunting spacecraft has been reworked for at least two years of productive new missions.
Exoplanet Portraits: A Tale of New Instruments
Exoplanet missions are shifting their goals from counting to characterizing, with multiple instruments coming online to directly image these alien worlds.
Two Ancient Exoplanets Discovered
Kapteyn’s star — a nearby star that likely formed outside this galaxy — hosts two planets more than twice as old as Earth.
