Happy World Penguin Day! Know your penguins! 18 different species, all found in the Southern Hemisphere, though the Galapagos lives on the Equator. The Emperor is the tallest at more than 1m. Many are threatened or endangered #WorldPenguinDay #penguins pic @PepomintNarwhalpic.twitter.com/xp4eQ9Lypt

‘One of the greatest voyages’ #OnThisDay #OTD in 1916, Shackleton left Elephant Island on 'James Caird' in search of rescue, with Worsley, Crean, McCarthy, Vincent & McNish. Their destination: South Georgia, 1500kms awaypic.twitter.com/WPHcoYxfcJ

It’s #EarthDay!

Venus and bright stars now visible at the South Pole. It’s been almost 4 weeks since sunset at the March equinox; with the Sun 9.8° below the horizon, it’s nautical twilight. Astronomical twilight begins in 6 days when the Sun reaches 12° below the horizon; pic @iceman_90Southpic.twitter.com/JusFQ8uoQT

Congratulations South Pole Telescope! One of the eight radio telescopes spanning the globe that make up the Event Horizon Telescope array - captured the first historic image of a black hole https://bit.ly/2DaQRPI  @SPTelescope pics @ehtelescope @iceman_90Southpic.twitter.com/yzJiLvBsb1

Winter is coming! daylight saving in Southern Hemisphere countries, Australia and New Zealand, has ended today; many Antarctic stations have adjusted their clocks, including South Pole, McMurdo and Scott Basepic.twitter.com/s49VcCSArX

The point on the ice sheet that covered the South Pole when Amundsen arrived at 90°S (the 1911 surface is now buried by 25m of snow accumulation). Today this flag is located 1km from the Pole, as the ice sheet moves 10m per year over the bedrock 2km below, pic @iceman_90Southpic.twitter.com/C1BlTwxQQe

Antarctic sea ice extent in March increased at slower-than-average pace, remaining well below range of past early southern autumn extents. Annual minimum extent for the 12 month cycle occurred slightly later than normal on 1 March, the 7th lowest in satellite record, pic @NSIDCpic.twitter.com/DSrlFIf8T7

Ice-strengthened oceanographic research ship Laurence M. Gould has arrived at Palmer Station on Anvers Is, to pick up the last of the summer personnel.

“Had we lived, I should have had a tale to tell of the hardihood, endurance, and courage of my companions which would have stirred the heart of every Englishman. These rough notes and our dead bodies must tell the tale” - Robert Falcon Scott, last diary entry #OnThisDay in 1912pic.twitter.com/h4w15eTxCL

Seismic survey on Totten Glacier, the largest in East #Antarctica, reveals network of subglacial lakes under the ice with large amounts of water. Up to 2km thick, the Totten Glacier has the potential to raise sea levels by 7m https://bit.ly/2CyoCKk  pic Nick Morgan @AusAntarcticpic.twitter.com/xIwfku94uq

And good bye Sun for six months…last of the refracted sunlight from over the horizon at the South Pole, the day after the Equinox, pic Robert Schwarz @iceman_90Southpic.twitter.com/YE7TFnVLn0

Happy birthday Johann! Celebrating Johann Sebastian Bach, born #OnThisDay #OTD in 1685; honored in #Antarctica with the Bach Ice Shelf, which occupies a bay in Alexander Island between Berlioz and Rossini Points! map @BAS_Newspic.twitter.com/74YlGrnGVO

#Equinox! The Sun is crossing the celestial equator heading North; the one and only sunset of the year at the South Pole is currently underway, bringing an end to six months of 24/7 sunlight at 90°South #SouthPole #Antarcticapic.twitter.com/O13rr7oh1M

Happy #StPatricksDay Here’s a great Irishman of #Antarctica: Tom Crean, veteran of 3 Antarctic expeditions; 1. last to see Scott alive; 2. saved lives of Lashly & Edward Evans! 3. sailed in James Caird! 4. traversed South Georgia with Shackleton & Worsley in search of rescue!!pic.twitter.com/EyOSQCyQWU

Days of long shadows: at the South Pole, the Sun rose 6 months ago, and in 4 days it will set at the March Equinox. Now only 2.7° above the horizon, the Sun casts a shadow 39m long on the 1.85m frame of Robert Schwarz, commencing his 15th winter-over at 90°South! @iceman_90Southpic.twitter.com/21HthuN8S7

Flag at half mast, Scott Base. We express our solidarity with #Christchurch on this tragic day. A great Antarctic gateway city, HQ for @AntarcticaNZ, & friend to the US, Italian & Korean Antarctic programs @NSF_OPP @ItaliAntartide our thoughts are with the families of the victimspic.twitter.com/9wPiFzDxf4
