Last minute E-carding

Dec
22

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

Dec
17

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

Dec
04

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.

News flash: Sticky tape generates X-rays

Nov
24

Recently a group of researchers from the University of California at Los Angeles announced what has been described by the New York Times as a "tour de force of office supply physics." The scientists measured X-ray flashes from a roll of Scotch tape as it was unpeeled.

FREE STUFF!

Nov
19

Now that we shamelessly have your attention, we'd like to invite you to take a survey about our newly redesigned website. We know, we know, surveys can be less than stimulating. To make it worth your while, we are offering the possibility of a free package of Chandra goodies – bookmarks, postcards, etc. – that will be mailed directly to you. We’ll pick 50 people randomly to get the stuff, and we’ll let you know if you’ve been chosen.

Happy Anniversary, Einstein Observatory!

Nov
17

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.

The Latest New Thing

Nov
06

If you haven't noticed by now, we like new things around here. In fact, it almost pains us to see something out there that's fun and exciting that we’re not a part of. So to remedy that, we just try to get Chandra involved with everything we can. The latest, in our humble opinion, is very cool.

From One X-ray Mission to Another

Oct
28

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

Oct
15

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.
