Carnival of Space #310 at the Chandra Blog

It's the height of summer here in the Northern Hemisphere, so that means there isn't a better time for the Carnival (of Space, that is)!

Remembering the Original Chandra

On August 21, 1995, the field of astrophysics lost one of its greats. Seventeen years ago this week, Subrahmanyan Chandrasekhar passed away. Chandra, as he was known to his friends and colleagues, was widely regarded as one of the foremost astrophysicists of the 20th century.

Astrophysics and the Olympics

It's not every day that we can mention "Chandra" and the "Olympics" in the same sentence, but today we can. That's because Stacie Powell, who will compete in the 10-meter platform diving competition for Great Britain at the London Olympics beginning today, is also working on her Ph.D. in astrophysics.

Intrepid Meets the Enterprise

Last week, the Intrepid Sea, Air, and Space Museum welcomed a very unusual guest (who will be staying quite a while): the Space Shuttle Enterprise. The Intrepid, which is located on the Hudson River in New York City, will be the Enterprise's new home now that the Shuttle program has officially ended.



A little bit after midnight (12:31 am EDT to be exact) on July 23, 1999, the Space Shuttle Columbia lifted off from the Kennedy Space Center in Florida. Onboard was what was then the largest payload ever carried by a Shuttle: the Chandra X-ray Observatory.

Meet An Astronomer: Julia Lee

Back by popular demand is our video blog series, Meet An Astronomer
Julia Lee is an associate professor in the astronomy department at Harvard. We caught up with Julia at a moment when she wasn't busy with her regular duties of running a research lab, teaching students, and everything else that a full-time position at a university like Harvard entails. Julia sat down with our "Meet an Astronomer" crew to explain how various choices she made led to her current career.

NASA'S Chandra Finds New Evidence on Origin of Supernovas

This Chandra image of the Tycho supernova remnant contains new evidence for what triggered the original supernova explosion. Tycho was formed by a Type Ia supernova, a category of stellar explosion used in measuring astronomical distances because of their reliable brightness. In the lower left region of Tycho is a blue arc of X-ray emission. Several lines of evidence support the conclusion that this arc is due to a shock wave created when a white dwarf exploded and blew material off the surface of a nearby companion star. This supports one popular scenario for the trigger of a Type Ia supernova. Understanding the origin of Type Ia supernovas is important because they have been used to determine that the Universe is expanding at an accelerating rate

"From Earth to the Solar System Lifts" Off

We are very excited to announce the launch of a new – and yet somewhat familiar -- project. Today, “From Earth to the Solar System” officially opens. As the name implies, FETTSS (our new favorite acronym) is a direct descendent of the “From Earth to the Universe” project.

Happy 21st Hubble
