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.

Boston Harbor is sprinkled with dozens of grass mounds, peeping out of the water like half-buried eggs. Don’t be fooled by these innocuous-looking islets, these are no ordinary islands: they are sunken drumlins. 🧪 www.iflscience.com/boston-harbo...

We wrote about this dataset on the NASA Earth Observatory way back in 2005. What a loss.

For decades, this iconic graph has provided clear observational evidence of one of the key indicators of global climate change - Arctic sea ice loss. It’s from the NSIDC "Sea Ice Index" Now, support of this crucial data is at risk. A visual lens to our changing poles (zacklabe.com/arctic-sea-i...).

Texas '...at the end of April, we have had 28 days of dust storms; for comparison, over the past quarter century, the average for an entire year is 22 days. You would have to go back to 1936—during the Dust Bowl—to find a year with more.' klaq.com/el-paso-dust...

About 600 million years ago, an asteroid blazed through the sky and smashed into land or shallow waters around Davenport Range, northern Australia. While much of the original impact crater has eroded, telltale signs of the collision remain imprinted. 🧪

For much of February and March of 2025, multiple NASA satellites observed a bloom that drifted across the Gulf of Oman and into the Arabian Sea Blooms typically occur in the winter/early spring and summer, when water temperatures, light conditions, and nutrient availability are favorable 🧪

In and around China's Yellow River delta the land is carved up into rectangles. Lots of them. Really, I wouldn't want to count them all. There are other shapes too, but it's mostly rectangles. There are still more on display in this much larger image. drive.google.com/file/d/1iCp1... #Landsat8

Hi - I'd like to share this story of what is happening at NOAA GFDL, where some of my colleagues and I worked until the mass firings at NOAA last week. "...the birthplace of weather and climate forecasting"

Excellent writeup of our recent #Alaska Kachemak Bay work that ties together everything from glaciers to fish. Thanks Adam - we all really appreciate this. Stellar example of how science journalism can turn dense papers on niche subjects into engaging "bigger picture" stories.

NEW: Asteroid 2024 YR4 may threaten Earth. It won't be the last. But, there's good news: we're about to get two new anti-asteroid weapons. For @theatlantic.com, I wrote about Vera Rubin Observatory and NEO Surveyor—and how both will make the world safer. www.theatlantic.com/science/arch...

I love to see NASA design a map so well that even the @nytimes.com graphics team can’t improve on it. 👏👏👏 Lauren Dauphin! Original story: earthobservatory.nasa.gov/images/15389... NYT story: www.nytimes.com/interactive/... #dataviz 📊 #cartography 🗺️
