This week, NASA announced the selection of three prestigious fellowships, each named after a distinguished scientist: Einstein, Hubble, and Sagan. Every year, NASA awards these fellowships to recent Ph.D.s in astronomy, physics or a related field. The Chandra X-ray Center oversees the Einstein Fellowships, which cover the topics in high-energy astrophysics. The Space Telescope Science Institute runs the Hubble Fellowships, and JPL is in charge of the Sagan ones.
People seem to be fascinated with the concept of sound in space. This was just underscored for us when we saw this great TED talk by physicist Janna Levin.
We have some personal experience with the public’s interest in the topic. Way back in 2003, we did a story on the black hole at the center of the Perseus Cluster. The energy generated by the giant black hole was responsible for sound waves propagating through the intercluster gas. (If you're curious, the black hole was bleating out a B flat some 52 octaves below middle C.)
OK, you probably couldn’t with Albert Einstein (who most likely wouldn't have appreciated the Paul Simon reference.) If Einstein had lived, he would have been celebrating his 132nd birthday today. Alas, he sadly died back in 1955, but, as we all know, he managed to squeeze in quite a bit during those years.
March 8th is International Women's Day (http://www.internationalwomensday.com/), an effort to mark the economic, political, and social achievement of women. From here at the Chandra blog, we'd like to extend that concept to include scientific achievements as well by highlighting our "Women in the High-Energy Universe" (http://chandra.harvard.edu/blog/taxonomy/term/19) series.
When I was a kid, my class was given ‘word problems’ for an alternative math lesson. You probably know the kind: two different trains traveling at different speeds, which one gets there first, etc. While these were possibly a little out of the norm, they didn’t quite excite the inner astronomer in me. Now, the folks at "Space Math @ NASA" have put together a comprehensive set of math activities for astrophiles of any age (or at least grades 3 and up).
Every so often, our talented team gets to play with other colors in the crayon box -- that is, wavelengths outside the regime that Chandra observes. We do this for a number of reasons, not the least of which is that something great usually happens.
Today marks the 25th anniversary of the loss of the Challenger Space Shuttle. For many of us, it was an unforgettable moment when we heard the news. It might have been the first time that many of us of a certain generation realized that flying into space wasn’t easy, nor was it always safe.

This is a hectic season with many reasons to celebrate. One of the oldest and, in many ways, practical rites during this time in December involves marking the winter solstice. Today, we know it as the shortest day (or longest night) in the Northern Hemisphere, and this year, the moment occurs at 6:38 pm Eastern time on Tuesday, December 21st.
Today is the anniversary of Carl Sagan's death back in 1996. For those of us who have dedicated our professional lives to communicating astronomy to the general public, we owe him a great deal of gratitude. After all, it was Carl Sagan who helped make astronomy accessible for everyone -- and emphasized the importance of doing so. His books, TV series, and public appearances really helped galvanize the public's interest in what lies beyond planet Earth.
Today, astronomy has many telescopes and observatories working to study the cosmos. And, most of these major facilities have education and public outreach offices – including Chandra – to help disseminate these results. We are thankful that those who came before us, like Carl Sagan, who helped paved the way for the work we are able to do.

There have been many odes and tributes to Chandra over its 11-year run so far, but here's one that we certainly never expected: Chandra immortalized in petroglyphs. The artist, Kevin Sudeith, carved an image of the spacecraft into rocks alongside a road in Montana. While we hope that Chandra lasts a very long time, it is certain that this tribute to the telescope will last even longer. So thanks to Kevin for his excellent art and his devoted interest in Chandra.
