Last week, we released the Chandra image of an object known as Cygnus X-1. At first glance, Cygnus X-1 might not look that important â€“ even with Chandraâ€™s excellent X-ray vision â€“ but this is one case where itâ€™s good not to judge a book by its cover.
Ten years ago tomorrow (August 26th), the official First Light image from Chandra was released to the world. The image was of the famous supernova remnant Cassiopeia A, taken less than a month after Chandra was deployed by the Space Shuttle Columbia.

OK, technically speaking, this week's International Astronomical Union (IAU) meeting is not on the beach in Copacabana, but it is in Rio de Janeiro. Most of the attendees are staying at hotels in the made-famous-by-Barry-Manilow section of Rio, but the conference is really being held at the Sul America Convention Center (see picture) in the central part of the city. (The alternate headline for this post was going to be "The Girl from Ipanema" so maybe the one being used now seems a little less cheesy by comparison.)
There are those of us who are experts, and then those of us who are not. Even some of us who have been working in X-ray astronomy can lose track of some of the basics. To help provide a little introduction or perhaps just a refresher, weâ€™ve put together a little thing we like to call â€œX-ray 101â€. Itâ€™s meant just to give a very quick overview of what Chandra is and what X-ray astronomy is all about.
As many of this blog's readers may know, Chandra is NASA's flagship X-ray mission but it's not the only major X-ray telescope in orbit. The other one is XMM-Newton, which was launched by the European Space Agency (ESA) just five months after Chandra in 1999. The great thing about Chandra and XMM-Newton is that many of their capabilities are complementary. In other words, scientists often use both and can combine the data for even stronger results.
Here at the Chandra X-ray Center, we work hard to make the images that you find on the public website. No, thereâ€™s no magic button that we push to make pretty pictures. In fact, there are countless keystrokes, mouse movements, and lots of thinking that go into these images of the cosmos that are fit for public consumption.
Not to give away my age, but I remember not too long ago using film when I took pictures. And then having (gasp!) to get them developed. It was a sad, sad world, but somehow we emerged into our current age of electronic enlightenment.
One of the greatest advantages of digital visualization, in my opinion, is the ability to share, comment on, and arrange images in a myriad of ways. And, of course, Flickr has been highly successful at taking these concepts to a new level.
Fifty years ago this week, on October 1st, the legislation creating the National Aeronautics and Space Administration, or NASA, was enacted. There will likely be a lot of buzz about this anniversary, and rightly so, since it has, among many other things, shaped our understanding of the Universe so dramatically.
