A new special issue of Science highlights research on Earth’s frozen places—from the Arctic to the Antarctic—and how it’s changing due to climate change and the geopolitical challenges this important work faces.

ALT Climate change in the polar regions of our warming world is threatening to transform many of its features, such as this icy tableau in the Fish Islands off the coast of the Antarctic Peninsula. There is still much to learn about these places before we know better what those changes may be.

🚀It’s launch day for #EuropaClipper!
The SpaceX Falcon Heavy is set to lift off from @NASAKennedy at 12:06pm EDT. The goal is to learn if there are places below the icy crust of Jupiter’s moon that could support life.
Here are 8 things to know!

A brilliant week of science, brought to us by @NASA and @esa at the gorgeous waterfront venue of the Harpa Centre here in Reykjavik. We will be bringing you even more highlights from the conference over the next week…
27 Sep 2024
What a venue! What an event!
#Cryo2ice is almost over, but not quite yet.
Time now to summarise this incredible "family reunion" of our milk and cookies, CryoSat and ICESat-2.
We're about to hear from all our chairs, before a wrap up from @tparrine & @Thorsten_Markus

In 1968, during Apollo 8, Bill Anders offered to humanity among the deepest of gifts an astronaut can give. He traveled to the threshold of the Moon and helped all of us see something else: ourselves. He embodied the lessons and the purpose of exploration. We will miss him.
ALT On Dec. 24, 1968, Apollo 8 astronauts Frank Borman, Jim Lovell, and Bill Anders became the first humans to orbit the Moon, and the first to witness the magnificent sight called “Earthrise.” As the spacecraft was in the process of rotating, Anders took this iconic picture showing Earth rising over the Moon’s horizon. In 2018, the International Astronomical Union commemorated the event by naming a 25 mile diameter crater “Anders’ Earthrise.” Image credit: NASA

The world's biggest iceberg is made up of a trillion tonnes of frozen pure water and is more than twice the size of
Greater London.
It's slowly moving towards the Southern Ocean and having a huge impact on the seas around it

Please tell me we're going to call it the #HalloweenBerg. Using the normal nomenclature (#A83) is so dull. This is the third large berg to come off the Brunt in three years. The decision of @BAS_News to move Halley base in 2016/17 looks ever smarter. bbc.co.uk/news/articles/c033…

It's done. The last great chunk of #MolarBerg (aka D28a), the biggest block of ice to come of the Amery Ice Shelf in 50 years, let go big style this week. Hydrofracturing shattered the remnant berg virtually overnight. 52S; 22W on 16/5/24. #NASA #Worldview
