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 ...

There is no question that the scientific ocean drilling program, throughout its history, has had a fundamental impact on our understanding of earth’s history. The science that has been accomplished has expanded our knowledge of plate tect ...

Back in 2005 and 2006, when Pluto’s second and third moons (Nix and Hydra) were discovered, searches by astronomers for still more moons didn’t reveal any. So the accidental discovery of Pluto’s fourth moon by the Hubble Space Telescope in mid-2011 raised the possibility that the hazards in the ...

Saw oystercatchers on a Puget Sound beach this week. Their beaks are a freakish orange-red: Oystercatchers, Whidbey Island, May 2013, by John Fleck To which Nora commented, “evolution, wtf?” Related posts: Caspian terns Vacation Evolution

I spent time this afternoon watching Caspian terns fishing off the beach next to the Coupeville-Port Townsend ferry. This guy was successful. Caspian tern, Whidbey Island, May 2013, by John Fleck Later, when I was wandering the backwater nearby, I apparently got too close to the terns’ nesting a ...

The Global Positioning System has completely revolutionised how geologists study the deformation of the Earth. If you leave a GPS receiver in a fixed location for days, months and years, it is precise enough to measure motions on the millimetre scale, allowing us to track strain building up acro ...
