On 17 March 2013, NASA cameras captured the brightest impact on the Moon seen in eight years of monitoring. It lasted only a fraction of a second, but at the brightness of a fourth-magnitude star it could have been seen by anyone with binoculars and possibly with the naked eye. Six of the 17 fra ...

When I went to geology school, I was already so advanced that I never used mnemonics—those anagram sentences that help students keep track of the names of the geologic time periods. A reader in the Forum has been using the good old sentence "camels often sit down carefully, perhaps their j ...

Geology takes in subjects of all sizes from planets to molecules. Many of these have a micro component—that's not to stipulate that they're microscopic, or even minuscule, just, well, hey take the quiz now and you'll see. The quiz is definitely not about minutia, and if you can get through ...

The people at Google Earth have unveiled a new feature of Earth Engine: time-lapse views of anywhere on Earth using satellite imagery back to 1984. My colleagues on Twitter have been exclaiming all morning: @rschott: "The Evolving Earth: Meanders & Dunes & Shorelines Oh my!" @kwi ...

It's exciting in a geeky way to learn that the deep-sea plateau called the Rio Grande Rise appears to contain granitic rocks. Dredging two years ago brought up samples, and this week the "video evidence" from a submersible dive to the Rise was cited as further proof. That doesn't seem like much ...

by L. Heineman My particular view of the water world is constrained by scarcity. We don’t move a lot of cargo on the Rio Grande or the Colorado, the two rivers in my immediate field of view. I forget, and our current trip to the Pacific Northwest has reminded me, of the magic of water in service ...

Over the past 8 years, NASA scientists have documented many small impacts on the Moon. The biggest, shown as the red square in Mare Imbrium, was found on a March 17, 2013 image. NASA image.NASA and University of Western Ontario scientists have discovered the largest impact observed to date on th ...

Hiked up to Giant's Ledge today with some nice folks from the Meetup.com group Ulster County Outdoors.  Typical Catskill's hike, mostly uphill one way and downhill the other with a rocky trail.  The views from Giant's Ledge were well worth it, however. Here's a panorama from the le ...

Earthquakes and tsunamis are great motivators, as are the pursuits. These are the reasons why a lot of time and resources have gone into studying the seismic, geodynamic, and hydrothermic systems in the Pacific Northwest. read more
