Every now and then, the Milky Way’s central, supermassive black hole tears apart a star and flings away some of its innards. Now astronomers think they know how to spot these cosmic spitballs.
Cannan Huey-You, just 11 years old, impressed professional astronomers this week with his research on a massive intergalactic gas cloud.
The Chandra X-ray Observatory has gazed at a small patch of sky for almost 12 weeks, revealing 1,008 X-ray-emitting sources — most of them supermassive black holes.
Astronomers suspect that a binary star system in Cygnus is preparing to make one star of two, erupting in a red nova visible to the naked eye.
An exciting year lies ahead for spaceflight involving astronomy and planetary science — by NASA and by other spacefaring nations.
It won't be a great year for lunar eclipses, with a deep penumbral event on February 11th and a partial on August 7th. But an annular solar eclipse is observable from the Southern Hemisphere on February 26th, and a total solar eclipse crosses the continental U.S. on August 21st.
When it comes to capturing a total solar eclipse, few can match the expertise of Fred Espenak. Get valuable tips from "Mr. Eclipse" himself during S&T's live webinar on Thursday, January 12th.
For the first time, a team of astronomers has placed a fast radio burst on the cosmic map, allowing them to better pinpoint its mysterious origin.
Everyone enjoys the brief and sometimes dazzling streaks of light from meteors, sometimes called "shooting stars." Sky & Telescope predicts that the two best meteor showers in 2017 will be the Quadrantids in early January and the Geminids in mid-December.
From the discovery of gravitational waves to the building evidence that a massive planet could exist beyond Pluto, it has been a thrilling year for astronomy research. We recap.
Download our monthly astronomy podcast to spot Venus and Mars in the west — and two star clusters high up — after sunset.
Thanks to some timely NSF support, the American Astronomical Society is offering dozens of small grants to U.S. groups that offer outreach programs tied to the 2017 s
Do you think 2016 has seemed unusually long? An international agency has decided to make it even longer.
The Quadrantids, one of the year's best meteor showers, peaks on the morning of January 3rd, is. But be ready for it — most of the action takes place over just a few hours.
Doing anything on New Year's Eve? Before you start toasting, don't miss an exceptionally close conjunction of Mars and Neptune.
Astronomer Vera Rubin, known for her revolutionary work confirming the existence of dark matter, died on December 25th. She was 88.
This beautifully detailed 6-inch globe lets you explore the amazing geology revealed by New Horizons during its historic 2015 flyby.
Maybe this gift-giving season you got a shiny new telescope to call your own. Congratulations — you could be on your way to discovering many amazing far things in the night sky. Although most of them are so far and faint that just finding and detecting them is the challenge! Whether your new scope is…
The red supergiant marking Orion's shoulder seems to be spinning too fast. Did it get a boost when merged with a smaller companion star 100,000 years ago?
New results from NASA's Dawn orbiter show that the largest asteroid (and acknowledged dwarf planet) must possess a global layer of water ice that lies just below its dark, dusty surface.
Try your hand at observing the handful of "shooting stars" delivered by this little-known annual meteor shower.
A Hubble image of a nearby, massive elliptical galaxy reveals tenuous filaments that appear to be connected to the growth of the galaxy's supermassive black hole.
Here's a quick guide to the essential features that you should look for when buying your first telescope.
Curiosity scientists have tracked Gale Crater’s changing environment as it became more, then less, acidic over millions of years. Microbial life could have survived in these conditions.
Welcome to Mars: the European Space Agency's ExoMars Trace Gas Orbiter sets up shop around the Red Planet.
