sarychev-volcano-eruption-cloudThe ultimate photography experience would be the opportunity to take the photograph of an erupting volcano from space!

“…Astronaut photograph ISS020-E-9048 was acquired on June 12, 2009, with a Nikon D2XS digital camera fitted with a 400 mm lens, and is provided by the ISS Crew Earth Observations experiment and Image Science & Analysis Laboratory, Johnson Space Center. The image was taken by the Expedition 20 crew. The image in this article has been cropped and enhanced to improve contrast. Lens artifacts have been removed. The International Space Station Program supports the laboratory to help astronauts take pictures of Earth that will be of the greatest value to scientists and the public, and to make those images freely available on the Internet. Additional images taken by astronauts and cosmonauts can be viewed at the NASA/JSC Gateway to Astronaut Photography of Earth. Caption by M. Justin Wilkinson, NASA-JSC….”

How Did Dinos Go Extinct

Share

After a long period without decent dino news (my new painting by Doug Chaffee has arrived, btw) we’re now being treated to just scads of new theories, extinctions, and all sorts of feathered critters.

My painting has arrived in time to crown my reading of the “new” debate about Dinosaur extinction. Sure, I know all the talk is about India, but I am partial to a volcanic end of things.

Did Dinos go extinct from a massive asteroid hit or from volcanism?

“…The cause of the dinosaurs’ demise is far from an open-and-shut case. Though many experts support the Chicxulub impact theory, some question whether the extinction was caused by an impact at all, and suggest that climate changes and volcanism were responsible. One line of reasoning holds that all three phenomena were to blame.

Gerta Keller, a geoscientist at Princeton University, found evidence for massive volcanic activity coinciding with the time of the extinction in an area called the Deccan Traps in India. Keller has advocated that this volcanism was the main culprit behind the dinosaurs’ downfall. Her idea has long been controversial and remains so. She is bluntly dubious of Chatterjee’s argument.

“We have worked extensively throughout India and investigated a number of the localities where Sankar Chatterjee claims to have evidence of a large impact he calls Shiva crater,” Keller wrote in an e-mail along with colleague Thierry Adatte of Switzerland’s Universite de Neuchâtel. “Unfortunately, we have found no evidence to support his claims… Sorry to say, this is all nonsense.”
