This tumblr's for all the great men and women of science for whom we owe our current understanding of the natural world; their achievements, their failures, and even their quirks, we celebrate them all.
For Science. For Inquiry. For Humanity.
I embroidered this Carl Sagan quote from Cosmos about how scientists used to be dumb about the planet Venus.
Next Mars rover will assess the Red Planet for human habitability!
NASA’s next Mars-exploring robot, slated for launch in 2020, will evaluate the planet’s ability to support human life, as well as collect samples that it may one day bring back to Earth! NASA researchers are actually taking submissions for experiments and instruments to load on-board the future craft, so send in your ideas!

NASA astronaut Karen Nyberg is a self proclaimed crafter. A week ago she made a stuffed dinosaur from scraps on the space station. The little T-rex is made form the lining of Russian food containers and the toy is stuffed with scraps from an old T-shirt. While many toys have flown into space, this is the first produced in space.
These images from Earth Observatory show islands creating ‘von Karman vortices’ in the stratocumulus clouds. In the animation you can see that each vortex is formed from alternating sides of the object that is impeding flow of the fluid such as clouds or soap films.
In the first image, the water droplets in the clouds create an optical phenomena known as ‘Glory’, making the rainbow to the left. However, this is different from a rainbow, in that it is formed from backwards diffraction meaning they are always directly opposite to the Sun.
Some selfies are more thought-provoking than others. Amazing what you can see in the reflection.
SpaceX successfully launched their first upgraded Falcon 9 rocket at 12pm EST (9am CST) from Vandenberg Air Force Base in California today. Sporting an elongated first stage, the vehicle’s 9 Merlin D-1 engines are more efficient and arranged in what SpaceX calls an “Octaweb” pattern, versus the 3x3 grid-like pattern from before.
The rocket launched a Canadian space weather observation satellite, Cassiope.

most hadn’t actually seen an image of one. Now, researchers from the Chinese Academy of Sciences have been able to visualize a hydrogen bond using atomic force microscopy, a technique that can deliver higher resolution than even a scanning tunneling microscope.
These are some scientific illustrations of ancient stone tools that I did last summer while working at the Smithsonian Tropical Research Institute.
My work was published in a journal by Elsevier, called the Quaternary International and appeared in Volume 301 “Radiocarbon Chronology of early human settlement in the Isthmus of Panama”.
