| Jupiter Wallpaper |
Nov 14, 2003 - Here's a new wallpaper of that amazing image of Jupiter released yesterday that was stitched together from 27 separate photos taken by Cassini. In order to make this your computer desktop, click the following link so the image comes up in your browser. Then right-click anywhere on the image and choose "Set as Wallpaper". I've made the image 1280x1024, so those of you with bigger monitors can really appreciate how it looks (but it'll still look great on smaller screens too).

I've also added this to the photo gallery, so if you really like it, you can order a printed copy - from a 4x6 snapshot all the way up to a 20x30 poster. Click here to access the Photo Gallery, and then choose Jupiter. It's the first image in the series.
Enjoy!

| ESO Watches Burst Afterglow for Five Weeks |
| Nov 14, 2003 - Gamma-ray bursts are some of the largest explosions in the Universe; one can generate more energy in a few seconds than the Sun creates in 10 billion years. It's believed they're caused when a super-massive star collapses, called a hypernova. Astronomers from the European Southern Observatory tracked the afterglow of a recent burst by using a technique called polarimetry, which lets them track the shape of the explosion. If it was a spherical explosion, the light would have random polarity, but they found that gas is flowing out in jets which are widening over time. |

| Nozomi is on a Collision Course with Mars |
| Nov 14, 2003 - The Mars-bound Japanese spacecraft Nozomi, which has been plagued with problems since its launch in 1998, could be on a collision course with the Red Planet, and might crash into it if engineers can't change its trajectory. Officials from the Japanese space agency will attempt to fire the spacecraft's engines on December 8 to kick it into a safer orbit. But before that, they need to fix the spacecraft's malfunctioning electrical. One worry is that Nozomi was never intended to enter Mars' atmosphere, so it wasn't carefully decontaminated - it could deliver Earth-based microbes to the Martian surface. |

| Ancient Rivers Lasted a While on Mars |
| Nov 14, 2003 - NASA's Mars Global Surveyor spacecraft has revealed new features on Mars that look like ancient river deltas. This discovery might help answer the mystery of how long water flowed on the surface of the Red Planet. The shape of this formation suggests that a river flowed into a body of water for quite a while, changing its course and building up layers of sediment over time. The area is about 13 km long and 11 km wide, and located in a crater in the southern hemisphere. |
