Though Ireland is known for the many shades of green that grace its grassy pastoral landscapes, there's one corner of the Emerald Isle where gray reigns supreme.

Lovely story on the BBC about iceberg a23a, which has given us decades of fun but is now nearing its end… Really enjoyed talking with Mark Poynting about this one-time behemoth. www.bbc.co.uk/news/resourc...

The journey of Iceberg A23a (largest, oldest, 'living' berg) since the beginning of 2024, as seen by NASA MODIS, including its five-month pirouette on the Taylor Column, short embrace by the pack ice in August, grounding on South Georgia's shelf in April, and baby calf.

Stunning footage from earlier today, when the new Kilauea eruption covered the USGS Webcam 3, which is situated in the Halemaʻumaʻu crater near the southern rim of the much larger Kilauea caldera. This *isn't* what the people of Pompeii saw. But it's not very far off.

Y'all the latest episode of the #Kilauea #eruption just went CRAZY. It looks like pressure built up enough to explode out the ground around the two existing vents (first few seconds), leading to a massive surge in lava fountaining.🌋🤯 USGS Live stream: www.youtube.com/watch?v=fiyt...

It’s been a hot and fiery decade for Kīlauea. The volcano in Hawaii is one of the most active in the world, and NASA tech makes it easier for volcanologists to monitor new developments. science.nasa.gov/earth/earth-...

For more than 26 years, Earth Observatory has been located at earthobservatory.nasa.gov. Now, as part of our next chapter, we are moving to a new home at science.nasa.gov/earth/earth-observatory. See you there! earthobservatory.nasa.gov/blogs/earthm...

An explosive #eruption of Hayli Gubbi #volcano, located SE of Erta'Ale in the Afar Rift (Ethiopia), began at ~08:30 UTC on Nov 23. Eruption onset was fortuitously captured by a @planet.com overpass at 08:31 UTC. Hayli Gubbi has no record of Holocene eruptions. Toulouse VAAC reporting ash to ~15 km.

Hard to believe we're in day 27 of the shutdown. At least the image frozen at the top of the website—this view of a ridge and river intersecting in a dune field in western China—is one of my all-time favorites. I could stare at this all day. earthobservatory.nasa.gov/images/15484...

Geologists have an amazing new superpower. With InSAR satellites, it’s possible to measure how much earthquakes move the land surface and even spot the earliest stirrings of volcanic eruptions from space. 🌍📡🌋 earthobservatory.nasa.gov/images/15477...

Each year as the sun starts to reappear over Antarctica I start the process of going through Sentinel2 imagery to find the locations of the 66 known emperor penguin colonies. Here is this year's first image, of Snow Hill, the most northerly colony. Can you spot the penguins?

This is not actually a subtweet of anything specific right now, but I do want to make a plea to everyone to a) attribute and link to the source of any information you're sharing b) only share posts that do so. This isn't (just) about credit, it's about creating a chain of custody for information.
