Try Out the Universe on Your Desktop

In the last year we have seen tremendous development in visualizing the Universe through the digital world. Google Sky and Wikisky are examples of this progress. These interfaces have taken well-known all-sky surveys and detailed observations to create virtual observatories that show our nearest planetary neighbors, like Mars and Jupiter, to the most distant galaxies in the Universe.

Give that telescope a blanket

One of the most important tasks involved with having telescopes in space is keeping them at the correct and constant temperature. It's not just because telescopes like Chandra like to be comfortable – it's crucial in making the instruments perform as they should and return accurate science.

Going Deep with Chandra

One of the most impressive accomplishments of the Chandra mission has been the improved understanding of the distant X-ray Universe. Chandra has accomplished this through deep X-ray surveys that generally involve pointing Chandra at a particular region of the sky that is not known to have any bright nearby objects and letting the camera collect X-ray light for an extended period of time.


Chandra Does Its Part For The Earth

When we talk about what Chandra observes, we're usually discussing things like black holes or galaxies or stars. But Chandra is a pretty amazing telescope and it can study many things in the Universe – including the Earth.


Where does the "X" in "X-ray" come from?

Here's a piece of high-energy astrophysics trivia (you never know when you might need to know these things). Where does the "X" in "X-ray" come from?


The Zen of Astrophysics

Speaking in broad generalities, there are two main classes of physicist: those who generate new hypotheses and those who generate new data. The former are called "theorists" and the latter, in most of physics, are called "experimentalists." In astrophysics, we're called "observers" because we can't do experiments in the traditional sense. We have no knobs to turn, no switches to flip; we can't turn the dial to a maximally spinning black hole just to see what happens (oh, what fun that would be!). Instead, we look at what's already there and try to figure out what it is we're looking at.


Live from LA

This week, the High Energy Astrophysics Division (HEAD) meeting is taking place at the Omni Hotel in downtown Los Angeles, California. What exactly is HEAD? It is one of the five divisions of the American Astronomical Society (AAS), which is the biggest organization of astronomers in the US (lots of scientists from other countries are members as well.) The AAS has meetings twice a year - in January and then some time in May or June - and then the divisions like HEAD (http://www.aas.org/head) also have their own separate meetings.


Having A Light Go On: A New Way To Study Supernovas

Dr. Carles Badenes is a Chandra postdoctoral fellow at Princeton, having spent the previous few years at Rutgers University. His main research focus is on supernova explosions and supernova remnants, particularly the class known as Type Ia.

Single Spacecraft Seeking Friends

The Chandra X-ray Observatory is now in its ninth year in orbit around the Earth, and things are sometimes lonely out there. So we've been helping Chandra to use the web to reach out to others who like to network online. Here are a few ways to get in touch with Chandra.
