Last minute E-carding

It sounds like a good portion of the United States got walloped over the weekend with snow and ice and seemingly everything in between. (Yesterday was, after all, the winter solstice and the official start of the season, so what else should we have expected?) While the white stuff can be beautiful, it can also put a damper on holiday errands. For those of us who might be lagging behind on getting their holiday cards in the mail, we here at Chandra can help you out.

Dark Energy Trailer on YouTube

By now, you've probably seen the news stories on our exciting and important new work on dark energy. For those of you who want even more, take a look at this posting on YouTube. The main scientist behind these results, Alexey Vikhlinin of the Smithsonian Astrophysical Observatory, put together a great movie describing the new science.

X-ray 101

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, we’ve put together a little thing we like to call “X-ray 101”. It’s meant just to give a very quick overview of what Chandra is and what X-ray astronomy is all about.

Happy Anniversary, Einstein Observatory!

While we like to focus on the current excitement in X-ray astronomy, sometimes it's good to look back. Last week marked the 30th anniversary of the launch of the Einstein Observatory. Back on November 13, 1978, the High Energy Astrophysics Observatory 2 was launched on Atlas-Centaur booster rocket. Shortly afterward, the satellite was renamed in honor of that little known scientist, Albert Einstein. While HEAO-2 is catchy, we think Einstein is a little easier off the tongue.

From One X-ray Mission to Another

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.

Aesthetics & Astronomy

Here at the Chandra X-ray Center, we work hard to make the images that you find on the public website. No, there’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.

Chandra joins the Flickr Commons project with the Smithsonian

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.

In case you haven't heard, there's an election going on. No, not that election. This one goes beyond national politics and covers the entire Galaxy and beyond.

A Long Look Back at History

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.
