Martian barchans

Is Ansel Adams still alive and in orbit around Mars?

From Astronomy Picture of the Day, April 22, 2012: Flowing Barchan Sand Dunes on Mars.

Barchans are crescent-shaped sand dunes, with two horns that point downwind. They form in areas of limited sand supply; on this image you can see that the dunes occupy less than ten percent of the plain. And they are very photogenic.

The description from the ESRI Map Book:

This map is a depiction of Rhode Island and southeastern Massachusetts/Cape Cod inundated by a 67-meter (73-yard) sea level rise resulting from a total melting of the polar ice caps. Although an unlikely scenario, the map was created as an attention grabber for display at the University of Rhode Island 2008 Honors Colloquium Lecture Series on Global Warming.

A good map can be artistic as well as informative; in fact the two often go together. The annual ESRI map books are available online or in book form (I am happy to own a couple editions).

Nature on canvas

Before there was color landscape photography, there was painting. One of the great landscape artists was Albert Bierstadt, whose Valley of the Yosemite is currently featured on a 42-cent stamp:

The Art Renewal Center advertises itself as the internet’s largest online art museum, and has hundreds of high-resolution Bierstadt paintings (as well as thousands of other paintings).

Musee d’Orsay

I did more in France than take pictures of bus stops named after famous scientists. Here are a few of my favorite paintings from the Musee d’Orsay:

Regatta at Argenteuil, Claude Monet, www.artrenewal.org, Musee d’Orsay. I’ve always wondered why there is a giant penguin hiding behind the bushes to the right of the house.
