NASA’s NuSTAR mission recently returned a striking image that shows the Sun’s active regions crackling with X-rays.
In our March 2015 issue, we ask noted amateur and professional astronomers to highlight the astronomy apps they use most. These are apps that every astronomer should have in their back pocket, ranging from practical planetarium and weather apps, such as Scope Nights and Sky Safari 4, to science guides, such as Exoplanet and...
The International Astronomical Union is hosting a public contest to name five of Mercury's craters, with a deadline of January 15.
In the February 2015 issue of Sky & Telescope, author Marcus Woo walks readers through the science of cosmic voids. Here, videos demonstrate a sense of cosmic perspective, taking the reader on flights through the universe both theoretical and observed.
Orphaned black hole or weird supernova? A mysterious source of radiation has left astronomers contemplating exotic explanations.
A bizarre set of galaxies in the Coma Cluster have lost most of their stars (or star-making material), making them especially rich in dark matter.
An ALMA submillimeter-wavelength image unveils the dawn of planet formation around a surprisingly young star in unprecedented detail.
The appropriately named Stella Kafka has been named the newest in a series of esteemed directors of the American Association of Variable Star Observers.
The University of Hawai'i, in partnership with the University of Arizona and Lockheed Martin, will sustain operations of the UKIRT infrared telescope.
Astronomers are peering into a galaxy cluster’s past, using Hubble’s Frontier Fields to measure the light from ghost stars cast adrift in galaxy collisions.
New IRIS results show a Sun rife with twisting and snapping magnetic fields, data that will elicit clues on what bakes the puzzlingly hot corona.
Find out where you can watch the partial solar eclipse taking place on October 23, 2014.
Astronomers have discovered a spike of X-ray emission in galaxy clusters — “ordinary” interpretations don’t hold up, so some are turning to dark matter for answers.
Despite skepticism from scientists and politicians alike, NASA is proceeding with its asteroid redirect mission and has found six candidates for exploration so far.
Newly published observations provide the first real evidence supporting a theory that tells us how black hole jets form.
Toddlers can gain a great deal from star parties, more than we might think possible. Here are some further resources for engaging youngsters at your next event.
A new study finds every stage of star formation in a single cloud, firmly backing a popular star-formation recipe.
Galaxies’ central black holes are surprisingly simple creatures at heart, but they have a complicated past. New studies are starting to remove history’s obfuscating veil.
A hive of stars is sailing toward Earth at more than 2 million miles per hour — and racing away from the giant galaxy it used to call home.
A bizarre X-ray flare first spotted in 2010 could be a signal from two black holes that will ultimately unite into a single beast.
