This iceberg was once the biggest in the world. Now it has just weeks left - BBC News A23a was once twice the size of Greater London but now its 40-year journey is coming to an end.

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.

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. Watch this space for updates!

Why is this infamous iceberg turning blue? Iceberg A-23A is bigger than New York City, but its days are numbered.

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.🌋🤯

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...

Very true! I should have worded that post differently. Thanks for flagging that.

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?
