The Milky Way over Texas

This 45 sec­ond time­lapse video of the “Galac­tic Cen­ter of the Milky Way” ris­ing over Texas Star Par­ty (2009) just gets more spec­tac­u­lar as it rolls along. William Castle­man cre­at­ed this sequence using a Canon EOS-5D, with expo­sures at 20 and 40 sec­ond inter­vals. This com­ple­ments nice­ly Stéphane Guis­ard’s panoram­ic view of the Milky Way tak­en from the Ata­ca­ma desert in Chile. See the The Milky Way in 360 Degrees here.

NASA Lauches Photo Archive on Flickr

This week, NASA rolled a big archive of his­tor­i­cal images into Flickr Com­mons, giv­ing users access to more than a half cen­tu­ry of NASA’s pho­to­graph­ic his­to­ry. The images are divid­ed into three neat sets – “Launch and Take­off,” “Build­ing NASA” and “Cen­ter Name­sakes” – and they’re all copy­right-free, mean­ing that you can share and use these images how­ev­er you like. You can jump into the archive here and watch it grow over time. Thanks for the heads up @eugenephoto! They’re always appre­ci­at­ed…

The Hubble Celebrates 20 Years of Discovery

20 years ago (April 24, 1990) the Hub­ble Space Tele­scope was launched, begin­ning a long peri­od of dis­cov­ery. Today, NASA is cel­e­brat­ing the Hub­ble’s 20th anniver­sary by releas­ing one of the many bril­liant pho­tos tak­en by the space tele­scope. The image shows us a small por­tion of one of the largest star-birth regions in the galaxy, the Cari­na Neb­u­la. As NASA goes on to describe it:

“Tow­ers of cool hydro­gen laced with dust rise from the wall of the neb­u­la. The scene is rem­i­nis­cent of Hub­ble’s clas­sic “Pil­lars of Cre­ation” pho­to from 1995, but is even more strik­ing in appear­ance. The image cap­tures the top of a three-light-year-tall pil­lar of gas and dust that is being eat­en away by the bril­liant light from near­by bright stars. The pil­lar is also being pushed apart from with­in, as infant stars buried inside it fire off jets of gas that can be seen stream­ing from tow­er­ing peaks like arrows sail­ing through the air.”

You can down­load NASA’s fea­tured pho­to in var­i­ous sizes and res­o­lu­tions here. You can also look through an amaz­ing gallery of Hub­ble pho­tos spon­sored by NASA, plus a beau­ti­ful col­lec­tion by Nation­al Geo­graph­ic’s here. Last­ly, NPR has a nice audio slideshow that fea­tures astronomers talk­ing about their favorite Hub­ble images. Thanks @lauraehall for the heads up on that.

The Milky Way in Time-Lapse Video

This hum­bling footage of the Milky Way was filmed on Mau­na Kea in Hawaii, the same loca­tion that recent­ly gave us footage of stars orbit­ing a black hole. This is, of course, not a coin­ci­dence. Mau­na Kea hosts the world’s largest obser­va­to­ry for opti­cal, infrared, and sub­mil­lime­ter astron­o­my. Thanks Robert for send­ing this our way.

Stars Orbiting Black Holes

Above, we bring you what astro­physi­cist Daniel Holz calls “one of the coolest movies in all of sci­ence.” What you see here is not exact­ly straight­for­ward. But it’s the work of UCLA astronomer Andrea Ghez, and it essen­tial­ly shows stars orbit­ing around a super­mas­sive black hole at the cen­ter of our galaxy over the past 15 earth years. Accord­ing to Holz, these orbits, filmed with the largest tele­scopes in the world on Mau­na Kea, are sim­ply “one of the best ways (short of the detec­tion of grav­i­ta­tion­al waves from black hole merg­ers) of con­firm­ing that black holes exist.” And it’s quite right­ly an “incred­i­ble feat of obser­va­tion­al astron­o­my.” For more, read Holz’s piece on Dis­cov­er’s Cos­mic Vari­ance blog. Anoth­er big thanks to Mike for pass­ing this one our way…

The Big NASA Image Archive

The Inter­net Archive has done it again. The San Fran­cis­co non-prof­it has teamed up with NASA to give you access to NASA’s image, video, and audio col­lec­tions. The con­tent is all avail­able in one sin­gle, search­able resource, which makes it the largest col­lec­tion of NASA’s media on the web. When you enter NasaImages.org, you’ll see that the media is nice­ly divid­ed into the fol­low­ing sec­tions. Uni­verse, Solar Sys­tem, Earth, Aero­nau­tics, and Astro­nauts. Now please help get the word out.
