No Ordinary Sight If you’re driving along Interstate 95 between Washington and Baltimore this July, don’t be alarmed if you see a large aircraft hurtling toward you from above. It’s not a a terrorist attack or a pilot dozing at the stick; it’s just NASA’s P-3B doing air quality research. The 117-foot plane is the workhorse […]
In the process of researching a feature for the Earth Observatory, I always come across fascinating tidbits that just don’t quite fit into my article. For instance, there’s this great carbon calculator tool from the University of Wisconsin-Madison. Early during the development of the recent carbon cycle feature, I heard NASA scientist Peter Griffith speak to […]
Maunder’s Return This sounds like a straight-to-DVD sci-fi title. But the National Solar Observatory announcement last week that the Sun could be entering a grand minimum should probably be filed with cable TV’s “What Would Happen If…” documentaries. The last time the Sun went quiet for a long stretch – dubbed the Maunder Minimum — […]

But we don’t publish photo-like images of every flood, and many readers wonder why. The severe floods affecting China this month are a perfect example. So far, […]
Every once in a while we get satellite imagery that shows things that are hard to imagine, like floating rocks. It’s helpful to have a different persepctive, like this series of photographs collected by The Atlantic. Fantastic.
If you want to see global warming’s signature, look to the Arctic. Up north, the air is warming and the ice is melting. As all of that reflective ice goes away, the Arctic Ocean is soaking up more sunlight, further enhancing warming. Melting Arctic ice is also contributing significantly to sea level rise. For two […]
Science writers and producers from across NASA recently sponsored an Earth Day video contest for the public. The theme was “The Home Frontier,” and the idea was to create videos that expressed what NASA Earth science means to you. Many people don’t realize that one of our agency’s most important missions is to study the […]
