Chandra's Got A New Look

Sep
29

The Chandra X-ray Observatory Center web site chandra.harvard.edu has been in existence for over ten years. In that time the Chandra Education & Public Outreach team has worked to improve content delivery, utilize new technologies and attempt to provide a fun, educational experience. Last week, the web group released a major revision that kept the overall basic design, navigation and search principles intact while allowing greater user control in content delivery. The new graphical design builds on existing elements but lends a more modern look.

How Far Away Are They?

Aug

Marusa Bradac: I do astronomy because it fascinates me. And it is the simplest things about it that amaze me most.

Jul
21

Nine years ago this week, Chandra was launched aboard the Space Shuttle Columbia (sadly lost in the tragedy of 2003). While the satellite has performed excellently since it was deployed on July 23, 1999, there was a little drama in getting it going.

This week, many Americans will celebrate the 4th of July by enjoying fireworks. We love to see the explosion, followed by the colorful debris field as it expands and rains down from the sky. And, fireworks are often slightly different from one another – even if they originate from the same type of explosion. Of course, if they have different types or proportions of chemicals before in the explosive itself, the fireworks can look dramatically different. And, don’t forget that the environment they explode into – include wind or clouds of smoke – can affect how they look.
