The Carnival of Space is a round up of astronomy and space-related blogs that started back in 2007. Every week, a different webmaster or blogger hosts the carnival, showcasing articles written on the topic of space. This week, it's our turn to host the Carnival here on the Chandra blog. Enjoy!

Welcome to this week’s Carnival of Space. We’ve got a lot to cover in the weekly blog carnival, so let’s jump right into it.

On WeirdWarp, Chris Dann features the latest view of the Centaurus A galaxy from the Hubble Space Telescope. This famous galaxy just seems to get better each time a telescope takes a new look.

Mike Simonsen at Simostronomy has an account of his recent trip to the Texas Star Party. Sounds like quite an event!

Over at Urban Astronomer, we find a write up of a newly discovered planetary system that didn't make too many headlines, but is fascinating nonetheless. This system apparently contains two giant planets around a pair of stars – a result that would have been pure science fiction just a few years ago.

If you’re one who follows astro-news regularly, you’ve probably heard by now that there will be a Chandra press conference. While we can't give out too much information in advance, we can say that this press conference covers black holes in the early Universe. This event will be televised on NASA TV and anyone can watch it live, beginning at 1pm Eastern, and follow #babyblackholes on Twitter

Not long ago a request came down from above for a list of Chandra’s achievements that have “completely transformed the way we have viewed our world, solar system, sun, or universe."

In other words, how many discoveries of the century have you made this year?

Cady Coleman was one of the astronauts who helped launch Chandra aboard the Space Shuttle Columbia back in July 1999. While we have always appreciated her many talents -- chemist, Air Force officer, astronaut, and mother -- we didn’t realize that we were missing out on another: flutist.

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).
