Each and every Monday, I pick the northern hemisphere’s celestial highlights (mid-northern latitudes) for the week forward, however take a look at my primary feed for extra in-depth articles on stargazing, astronomy, eclipses and extra.
The Evening Sky This Week: December 11-17, 2023
The overall week of the 12 months with a brand new moon makes it one of the most ultimate, with a sky darkish sufficient for simple stargazing. Alternatively, a couple of atypical occasions are taking place this week, from a unprecedented eclipse of the intense crimson famous person Betelgeuse to the height of the most efficient meteor bathe of the 12 months, the Geminids.
Right here’s the whole lot you wish to have to learn about stargazing and the night time sky this week:
Monday, December 11: Betelgeuse Occulted By way of An Asteroid
Top above the jap horizon at round 8:17 p.m. EST this night, in step with Sky & Telescope, Orion’s vivid crimson supergiant famous person Betelgeuse will disappear from view at the back of an asteroid as observed via the bare eye. In an rare once-every-few-decades tournament, an asteroid known as 319 Leona will go in entrance of Betelgeuse and block its gentle for a couple of seconds as a shadow falls throughout Earth’s floor. It might purpose a “ring of fireplace” annular eclipse. Alternatively, it’ll most effective be visual from a slim trail around the Earth’s floor from Asia to Florida and Mexico by the use of southern Europe. Detailed knowledge can also be discovered right here and right here.

The purpose is Mercury’s orbit of the solar, which is rather elliptical. When it will get with reference to Earth all the way through its “inferior conjunction”—presently—its motion in opposition to the background of stars seems to decelerate. Mercury turns out to head backward in short as Earth overtakes it, just like for those who overtake a automobile at the freeway. It’s just a topic of standpoint and has no importance to people.
Wednesday/Thursday, December 13/14: Geminid Meteor Bathe Peaks
The Geminid meteor bathe will height in a single day when as much as 150 multicolored meteors may well be visual from the northern hemisphere. A transparent night time is very important—and a gloomy sky will assist. Fortunately, the moon shall be totally absent. Even higher for the ones now not short of to face round within the chilly overdue at night time, Gemini—the plain supply constellation—shall be top within the sky as true darkness descends.

They’re named after Ferdinand Magellan, the Portuguese mariner who led the primary a success circumnavigation of the Earth from 1519 to 1522 (even though he died at the approach).
The days and dates given observe to mid-northern latitudes. For essentially the most correct location-specific knowledge, seek the advice of on-line planetariums like Stellarium and The Sky Reside. Take a look at planet-rise/planet-set, break of day/sundown and moonrise/moonset occasions for the place you’re.
Wishing you transparent skies and huge eyes.
