Have you noticed that Orion the Hunter—one of the most iconic and familiar of the wintertime constellations—is looking a little… different as of late? The culprit is its upper shoulder star Alpha Orionis, aka Betelgeuse, which is looking markedly faint, the faintest it has been for the 21st century.

Ready for the final ‘Ring of Fire’ solar eclipse of 2019? The final eclipse of the year kicks off this week on Wednesday, early on December 26th the day after Christmas, with an annular solar eclipse spanning the Indian Ocean region from the Middle East to the western Pacific.

Looking forward to the next bright comet in 2020 or beyond? You’re not alone. Though we’ve had a steady string of decent binocular comets over the past few years, we haven’t had a good naked eye comet since W3 Lovejoy beat solar death during its blistering perihelion passage in 2011. But this survivor turned out to be bashful, and headed for southern hemisphere skies… Comet P1 McNaught followed suit in 2007, hiding from northern hemisphere observers at its best. And we all remember what happened to Comet S1 ISON—touted as the next great ‘Comet of the Century’ on U.S. Thanksgiving Day 2013. Here it is almost 2020, and you have to go allll the way back nearly a quarter of a century to Hale-Bopp and Hyakutake to remember just how brilliant a good naked eye comet can be.

December means chillier climes for northern hemisphere residents, a time to huddle inside near the campfire, both real and cyber. I’ve always thought this was a shame, as the cold crisp nights of winter also offer up sharp, clear skies. Over the past decade or so, December gives observers another reason to brave the cold: the Geminids.

Get ready: The conjunction queries are inbound. “Did you see those two bright things in the sky last night?” Says a well-meaning family member/friend/coworker/random person on Twitter who knows you’re into astronomy. “They were HUGE!”

One of the finest spectacles in astronomy is to witness the passage of one object in front of another. This can transpire as an eclipse, an occultation, or a rare event known as a planetary transit. We get a shot at seeing just such a singular event next Monday on November 11th, as a transit of Mercury across the face of Sol occurs for the last time this decade.

A new study hints at a possible fascinating twist in human evolution. Did a chain of cosmic events triggered by a nearby ancient supernova force humans to walk upright?

Has twilight looked at little… purple to you as of late? The ‘purple sunset’ effect is subtle, but currently noticeable on a clear evening. Sunsets are always colorful events, as the Sun’s rays shine through a thicker layer of the atmosphere at an oblique angle, scattering out at longer, redder wavelengths. When the air is clear and relatively dust free, this effect is at a minimum… but when the upper atmosphere becomes saturated with dust particles and aerosols, the sky can erupt in a panoply of colors at twilight.

A unique 3d printed telescope named the Analog Sky Drifter may spark a revolution in amateur telescope making.

Happen to be in Europe, Africa, Asia or Australia on Tuesday night, July 16th with clear skies? If the July weather cooperates, you’ll have a good view of a fine partial lunar eclipse, the final lunar eclipse for 2019.
