Catch the Quadrantid Meteors (If You Can)

The Quadrantids, which peak on the morning of January 3rd, is one of the year's best meteor showers. But this shower isn't spread out over several days — most of the action takes place over just a few hours.

Here's a riddle: What's the strongest annual meteor shower that practically no one's heard of?
Answer: The strong but elusive Quadrantid meteor shower — elusive because the peak lasts just a few hours in the first days of January. The "Quads" can in theory deliver at least 1 meteor per minute under excellent sky conditions — the idealized zenithal hourly rate (ZHR), for someone with perfectly dark skies and the meteor's radiant overhead — is a very high 120. But in practice few observers ever see anything close to this many, because the shower's maximum activity lasts only several hours and is easy to miss.

Solar and Lunar Eclipses in 2017

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 the solar offerings are much better, with an annular (ring) eclipse observable from the Southern Hemisphere on February 26th . . . and the Big One — a total solar eclipse crosses the continental U.S. — on August 21st.

Meteor Showers in 2017

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 2016 will be the Quadrantids in early January and the Geminids in mid-December.

Check Out Breathtaking Images From NOAA’s Newest Satellite - In a word: wow

Weather satellites have advanced by leaps and bounds since the United States’ first was launched in 1960. These crafts have transformed what scientists can do in many fields—from communications to weather prediction. But if you think weather satellites are as good as they're going to get, think again. As The New York Times’ Nicholas St. Fleur reports, NOAA just released images from its newest weather satellite. And they’re so gorgeous, they might give you a new appreciation for the planet on which you live. The images are the first ever captured by GOES-16, a new weather satellite deployed by the National Oceanic and Atmospheric Administration. The satellite is currently 23,000 miles above Earth. And, using a barrage of high-tech instruments, is designed to make U.S. weather prediction and observation better.

Stunning Pictures Show an Alien Moon Eerily Like Earth

When it landed on Saturn’s hazy moon Titan in 2005, the Huygens probe revealed a surprising world of lakes, rain, winds, and wonder. Twelve years ago, a small spacecraft parachuted through a thick, extraterrestrial haze and drifted down toward an alien surface. It punched a small hole in the icy ground, bounced, slid, and wobbled. During its descent and those moments on the surface, the probe gathered enough data to give scientists a glimpse of an alien world that looks deceptively Earth-like.

Aldebaran's Disappearing Act on March 4th

On the night of March 4th, all you'll need are your eyes to watch the Moon occult Aldebaran. Better yet, place yourself on the graze line. It can't get much better than this: an occultation of the brightest star the Moon ever crosses, visible across most of the U.S. on a Saturday evening, with the Moon barely first-quarter (46% sunlit), and the star's dark-side disappearance visible without optical aid.

In a first for the Postal Service, this stamp actually incorporates two images in one using thermochromic ink. If you rub your fingers over the black Moon disk that's occluding the Sun, check out what it transforms into.

AAS’s Advice for Safe Solar-Eclipse Viewing

In response to alarming reports of potentially unsafe eclipse viewers flooding the market as the coast-to-coast solar eclipse of August 21st draws near, the American Astronomical Society (AAS) has revised some of its safety advice to the public.

How can you tell if your “eclipse glasses” or handheld solar viewers are safe? It is no longer sufficient to look for the logo of the International Organization for Standardization (ISO) and a label indicating that the product meets the ISO 12312-2 international safety standard for filters for direct viewing of the Sun’s bright face. Why not? Because it now appears that some companies are printing the ISO logo and certification label on fake eclipse glasses and handheld solar viewers made with materials that do not block enough of the Sun’s ultraviolet, visible, and infrared radiation to make them truly safe. Some sellers are even displaying fake test results on their websites to support their bogus claim of compliance with the ISO safety standard.
