It’s been a really active time for the Earth Observatory and volcanoes. In the past three weeks, we’ve posted images of a night-time eruption of Shiveluch, ongoing activity at Puyehue–Cordón Caulle, daytime activity at the Kizimen Volcano, and my own favorite, a brand new island in the Red Sea. And those are just the images […]
The new feature story, Seeing Forests for the Trees and the Carbon, discusses the need to form a three-dimensional picture of the world’s forests. Such a three-dimensional picture includes tree canopy height (below). Although canopy height in the Amazon Rainforest doesn’t match those of the Pacific Northwest or Southeast Asia, it still far exceeds the […]
On January 11, 2012, Google celebrated the 374th birthday of geology pioneer, Nicolaus Steno, with a special Google Doodle. Steno was a 17th-century anatomist and pioneering geologist. After dissecting a shark head, he realized that “tongue stones” — believed to belong to snakes turned to stone — were actually shark teeth. In Steno’s era, […]
For a month in the fall of 2011, NASA staff conducted an experiment of a different kind. They shared satellite images and maps with Chicagoans, but not in a classroom or a museum. The images of Earth were posted at malls, at bus and train stations, in O’Hare Airport, and on roadside billboards. The experimental question […]
Some of the world’s largest companies suffered multimillion-dollar losses from flooding or drought in the past year, according to a November 16 report from The Guardian. Citing a study from the Carbon Disclosure Project, The Guardian stated that although too much or too little water can affect the profits of large companies, many of those companies […]
When Music and Climate Change Meet During a recent event that highlighted the intersection of art and science, NASA climatologist Gavin Schmidt offered an intriguing pitch (see 5:15 in the video above) for a climate change symphony that would use music to tell the story of Earth’s long and varied geologic history. “There are trends in the tides […]
It’s Earth Science Week. What are you doing to celebrate? Our colleagues within NASA and at other institutions have organized a series of educational and outreach activities this week that showcase our science and the people behind it. Some highlights include: + A webcast with NASA’s chief scientist, Waleed Abdalati, from 1-2 p.m. Eastern Time […]
One of the best surprises of my life was turning on my brand-new iPhone—before it had even been activated—glancing down at the screen, and seeing an image I had made. Apple chose the NASA Blue Marble for the default welcome screen and wallpaper, and I had no idea beforehand.
Here's how I did it.
During every minute of the day, every day, a volcano is erupting somewhere on Earth. Actually, it’s more like a dozen. Or two. Satellites capture much of this activity, and we try to highlight as many eruptions as possible, but for one reason or another (like clouds) some of them fall through the cracks. Here […]
