This is a blog run by Deflare about space travel and exploration, and the beauty of the stars. I'm always looking for more material to post, so any art, photos, stories, or news articles you have to share would be appreciated!
(Note: If I mistag something or post something that the creator wants me to take down, please let me know in an Ask!)

8 Minutes of the Earth’s Rotation
How I wish our planet’s movement was this apparent while staring at the night sky. It could probably make a lot more people realize just how tiny we are compared to this vast unexplored galaxy above our heads.
This is a stack of 70 pictures with a 5 second exposure each at ISO 3200 and f/2.2.

You guys like Saturn, right? Here’s a whole gallery of Saturn GIFs, from rings to moons, captured by the Cassini spacecraft. They’re part modern art and part science.
Next to the Voyager twins, I think Cassini might be the best satellite NASA ever launched. Certainly takes the best pictures. Tumblr’s own staceythinx has an iPad app called Cassini HD that features even more photos, plus color, plus science.
With deference to the genius of David Bowie, here’s Space Oddity, recorded on Station. A last glimpse of the World.
Huge thanks in the making of the video to the talented trio of Emm Gryner, Joe Corcoran and Andrew Tidby, plus Evan Hadfield and all at the CSA.

NASA’s Solar Fleet: Capturing the Awesome
Here’s a fantastic video showing a May 1, 2013 solar eruption from four different NASA solar observation spacecraft. You can appreciate the different perspectives and filters that are offered by SDO, SOHO and the STEREO twins, and why the big picture is always more informative than any alone.

Hubble has spotted an ancient galaxy that shouldn’t exist
This galaxy is so large, so fully-formed, astronomers say it shouldn’t exist at all. It’s called a “grand-design” spiral galaxy, and unlike most galaxies of its kind, this one is old. Like, really, really old. According to a new study conducted by researchers using NASA’s Hubble Telescope, it dates back roughly 10.7-billion years — and that makes it the most ancient spiral galaxy we’ve ever discovered.“The vast majority of old galaxies look like train wrecks,” said UCLA astrophysicist Alice Shapley in a press release. “Our first thought was, why is this one so different, and so beautiful?”

Teleoperator Retrieval System (TRS), 1979
This TRS spacecraft is illustrated being used to re-boost the Skylab space station to a higher orbit. An early Space Shuttle flight would have boosted Skylab to a higher orbit, adding five years of operational life. The TRS (which was on contract with Martin Marietta for $26 million) contained about three tons of propellant, remote-control capabilities with TV cameras and was designed for duties such as space construction and servicing and retrieving satellites the shuttle could not reach. After rescuing Skylab, the TRS would have remained in orbit for future use. Alternatively, it could have been used to de-orbit Skylab for a safe, controlled re-entry and destruction.
However, development of the Shuttle was delayed, and Skylab reentered Earth’s atmosphere and disintegrated in 1979, with debris striking portions of Western Australia.
Threading the Corona
Top: The magnetic filaments of the sun’s corona, captured at top by Miloslav Druckmüller in a composite of 38 different images during a solar eclipse. You’ll want to see the super-huge version here, trust me. It will change you.
Bottom: “Coronal rain” captured by NASA’s SDO satellite. The superheated coronal plasma is seen traveling along magnetic field lines during a coronal mass ejection.
The corona cooks at over a million degrees Kelvin compared to the relatively frigid 5800 K of the photosphere below it. Exactly why this plasma is so superheated isn’t completely known, but it might be subject to the same kind of magnetic induction as an electric generator. Whatever the cause, the normally invisible lines of the sun’s magnetic field are drawn in brilliant form within the corona, and charged plasma is the paint.
You can get a good look at the solar corona today (right NOW for those catching this post live at 5:30 PM ET on May 9th) during today’s annular eclipse, being broadcast live from the South Pacific by the Slooh Space Camera.
