You Can Call Me Al

Mar

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.

IWD 2011 on the Chandra Blog

Mar

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.

Math + Science = Fun

Feb
15

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).

"Hidden Treasures" Found

Feb
03

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.

Somber 25th Anniversary

Jan
27

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.

Happy Winter Solstice

Dec
21

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.

Remembering Carl Sagan

Dec
20
Carl Sagan

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.

Chandra and the Glyphs

Nov

Chandra glyphs

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.

Happy Anniversary, X-rays!

Nov

Google X-ray

Today, Google is marking the 115th anniversary of the discovery of X-rays by William Roentgen, a German physicist. Here at the Chandra blog, we are not sure if this exact date is the most important one, but we do know that he made his discovery some time during 1895. And, hey, we are always in the mood for a little celebration of all things high-energy.
