"Equatorial Mars is actually quite mild compared to the South Pole … it's totally otherworldly," says Dr. Thomas Leps. Thomas Leps BICEP/Keck South Pole Telescope U.S. National Science Foundation physics.aps.org/articles/v16/51

Picture of the path out to DSL and SPT, from BICEP/Keck winterover manwei! Even though its past #sunset, the glow of the Sun over the horizon should still be visible for a few more weeks. #southpole #Antarctica

Cool picture from BICEP/Keck winter over Manwei Chen! Manwei is on the roof of the DSL building, which SPT shares with BICEP3, showing off his night vision red light headlamp #southpole #Antarctica

Greetings from the BICEP/Keck collaboration meeting 2023 in Cambridge, MA

For this past week's BICEP/Keck collaboration meeting, I baked Chessmen-style butter cookies with Antarctica themes, CMB polarization themes, and BICEP themes: mpetroff.net/2023/07/bicep-…

Great observing weather at the #southpole this past week, and a great opportunity for some amazing pictures of the sky by SPT winterover Kyle Ferguson! Is this #lidar on all the time?!? #Antarctica

New SPT result: "A Measurement of Gravitational Lensing of the Cosmic Microwave Background Using SPT-3G 2018 Data"! Nice demo using only the 1st half-year of data from SPT-3G at arxiv.org/abs/2308.11608 #nsffuned #southpole

A “muon shot” aims to study the basic forces of the cosmos. But meager federal budgets could limit its ambitions. nyti.ms/3uQSEqQ

Exciting news! The US particle physics community is rallying behind CMB-S4, the next-gen experiment to uncover primordial gravitational waves, evolving from BICEP/Keck's pioneering work. Big Bang observatory tops wish list for big US physics projects nature.com/articles/d4158…

Remarkable picture by Kevin Zagorski of a KBA Twin Otter passing in front of the SPT! Lots of small plane activity across the runway in mid-to-late December doing official U.S. National Science Foundation OPP activities, and also from tourists groups visiting #southpole #Antarctica!

Exciting announcement from European Space Agency, that LISA is getting the go-ahead! Also nice to see the CMB, including the South Pole Telescope and BICEP/Keck, pictured in their press release, highlighting our complementary search for gravitational waves! esa.int/Science_Explor…

Every year BICEP/Keck does an extensive set of calibration measurements just before #Sunset that involves measuring sources on the rooftops of DSL/MAPO. Last week, Kevin Zagorski got a great picture of SPT while helping take down the setup last week on the MAPO roof! #Antarctica

Almost #Sunset at the #southpole #Antarctica, our winterover Josh captured this great silhouette of the CMB telescopes (BICEP/Keck) in the Dark Sector and the Sun on the horizon!

SPHEREx Caltech instrument team is ready for #SPIEastro Overview of the instrument integration and testing at 2:30pm in 303/304 by proj scientist Dr. Phil Korngut followed by posters tonight by Dr. Howard Hui and yours truly! Caltech NASA JPL @LaurieofMars

Smiling faces all around at our yearly collaboration meeting University of Cincinnati! Excited to plot our next steps towards groundbreaking discoveries about the early Universe with our friends from South Pole Telescope at the South Pole! U.S. National Science Foundation #Antarctica #southpole

Congratulation's to SPT's Kimmy Wu about getting a DOE Office of Science early career award! www6.slac.stanford.edu/news/2024-09-1…

James Cornelison and Annie Polish on how BICEP/Keck will calibrate their polarisation measurement, allowing them to give the most direct measurement of CMB birefringence (in 2025 hopefully!) About this paper and future work: arxiv.org/abs/2410.12089

Happy Thanksgiving from all the SPT and BICEP/Keck team at the South Pole! #Thanksgiving #Antarctica
