Randomly ran across this really cool 3D map of the Local Stellar Neighborhood created with three.js.

The pictures of the night sky captured and edited by Rogelio Bernal Andreo are remarkable for their quality and detail. Every snapshot of the sky contains a beautiful array of color and texture. Check out his mosaic of the Orion constellation. Also, visit Andreo’s website to see these stunning images in HD.
Astrophotographer Stephane Guisard created a mosaic of the Milky Way’s central bulge with 1200 images and 200 hours of exposure time. The resulting picture is just remarkable. Check out the HD zoomable version here.
Chandra X-Ray observatory, named after Subrahmanyan Chandrasekhar, has provided scientists with the best x-ray images ever taken of the universe. To explore the satellite’s mission and its discoveries, I would recommend reading The Restless Universe: Understanding X-Ray Astronomy in the Age of Chandra and Newton by Eric Schlegel.

It’s a rare conversation that mentions the importance of women in the history of math and science. I am not too sure why, as there have been many important women in the history of math and science. To prove this, just check out Hypatia, Emmy Noether, and Henrietta Swan Leavitt. Leavitt made the discovery that Cepheid variable stars are the key in finding the distance to galaxies. To be more direct, she found out how to measure the universe. Anyone interested in this story should read George Johnson’s book, Miss Leavitt’s Stars: The Untold Story of the Woman Who Discovered How to Measure the Universe.
