At Union Glacier Camp, totality takes place at 07:44:55 UTC. Other research stations across the icy continent will experience a partial solar eclipse. https://www.timeanddate.com/live/eclipse-solar-2021-december-4 … from Union Glacier Camp ©Christopher Michel/ALEpic.twitter.com/HHCMFmgPKb

It's happening! A total solar eclipse will soon cross Antarctica and the surrounding region from 05:29 to 09:37 UTC. Only a lucky few (including a colony of Emperor Penguins) will see the eclipse. https://www.timeanddate.com/live/eclipse-solar-2021-december-4 … from Union Glacier Camp ©Christopher Michel/ALEpic.twitter.com/ll0EzXc0bl

If you're not in Antarctica, you can still follow the eclipse with us. We’re not doing a hosted live show, but we will have updates on our live blog from 05:30 UTC. https://www.timeanddate.com/live/eclipse-solar-2021-december-4 …pic.twitter.com/g4YTlklvD1

John tells us: 'The team here is really excited about being able to witness the eclipse on Saturday morning. During the summer, the Sun never sets below the horizon so even at 4 am we should see the effect of the eclipse.' https://www.timeanddate.com/eclipse/solar/2021-december-4 …pic.twitter.com/IM08w9U4SG

Tomorrow, December 4, there's a total solar eclipse across Antarctica. John Law, an Antarctic Atmospheric Scientist at Rothera Research Station, is one of the lucky few to be able to see the eclipse, if the clouds stay away, that is. https://www.timeanddate.com/eclipse/solar/2021-december-4 …pic.twitter.com/8IOm6S4JKg

And to take your minds off the dark cold days (or the upcoming sweltering summer), here's a cool fact about Dec 2021: the first 9 days of the month are all #palindromedays when written in mm-d-yy format! https://www.timeanddate.com/date/palindrome-day.html … ©http://bigstockphoto.com/Juriahah pic.twitter.com/AbV6bQ92my

It is December 1 today! It's officially the start of meteorological winter in many Northern Hemisphere countries. And the start of meteorological summer in Southern Hemisphere countries. https://www.timeanddate.com/calendar/months/december.html … ©http://bigstockphoto.com/Juriahah pic.twitter.com/75SCKIl8Tr

On Nov 27 (exactly 12:27 UTC) the #Moon will reach its #ThirdQuarterPhase. Tidal ranges are smallest around #QuarterMoons, because the gravitational forces from Moon & #Sun work against each other to produce #neaptides. https://www.timeanddate.com/astronomy/moon/third-quarter.html … ©http://timeanddate.com .pic.twitter.com/ideMGIjaTO

It will help us answer questions such as why is the solar corona, the Sun’s outer atmosphere that becomes visible during a total solar eclipse, millions of degrees hotter than the Sun’s surface?

Why hazardous? Because Earth is surrounded by space debris, ranging from abandoned rockets to tiny flecks of paint, all of which pose a risk to spacecraft. Solar Orbiter is on a mission to study the Sun https://www.timeanddate.com/astronomy/sun/about …. Image: ESA/NASApic.twitter.com/JhRSFKvfiB

Good luck to our friends at the ESA - European Space Agency! At 04:30 UTC on November 27, their Solar Orbiter spacecraft will perform a hazardous flyby of Earth—passing just 460 km above North Africa and the Canary Islands. https://www.timeanddate.com/astronomy/sun/about … Image: ESA/NASApic.twitter.com/f2AXKnRThA

Among those best positioned to see totality will be the inhabitants of the Gould Bay Emperor Penguin Colony in Antarctica. https://www.timeanddate.com/eclipse/solar/2021-december-4 … ©http://iStock.com/flammulated pic.twitter.com/Xme059rreQ

On December 4, at New Moon, there will be another Earth-Moon-Sun alignment, this time producing an “only just” total solar eclipse. Why “only just”? Because the Moon’s dark shadow just strikes the very bottom of the Earth. https://www.timeanddate.com/eclipse/solar/2021-december-4 … ©http://iStock.com/flammulated pic.twitter.com/FLGasmhiQd

Eclipses (like penguins) always come in pairs. Last week’s Full Moon gave us a near-perfect alignment of the Sun, Earth, and Moon, leading to an “almost” total lunar eclipse. https://www.timeanddate.com/eclipse/solar/2021-december-4 … ©http://iStock.com/flammulated pic.twitter.com/gNXoVasJCV

It is almost showtime! Watch the once-in-a-lifetime "almost" total lunar eclipse with us. Starting very soon! https://www.timeanddate.com/live/eclipse-lunar-2021-november-19 … #almosttotallunareclipse #lunareclipse #eclipselivestream #eclipselive #partiallunareclipsepic.twitter.com/imS61wZpkJ

Last but not the least in our November 18-19 "almost" total lunar eclipse of the Micro Beaver Moon streaming partner profile series: the Royal Astronomical Society of Canada – Sudbury Centre.

Meanwhile, in the other direction from Orion’s Belt—on the far left of this image—we find Sirius, the brightest star in the night sky. Watch the eclipse live with us: https://www.timeanddate.com/live/eclipse-lunar-2021-november-19 …pic.twitter.com/FQrRUGd2fF

The three stars of Orion’s Belt point the way to the reddish eclipsed Moon, which in turn lies just below the bright group of stars that make up the Pleiades cluster.pic.twitter.com/wOPbaLGRrR
