Top Story
New observations from
NASA's Spitzer Space Telescope
indicate that the nearest planetary system to our own has two asteroid belts. Our own solar system has just one.
The star at the center of the nearby system, called Epsilon Eridani, is a younger, slightly cooler and fainter
version of the sun. Previously, astronomers had uncovered evidence for two possible planets in the system,
and for a broad, outer ring of icy comets similar to our own Kuiper Belt.
Now, Spitzer has discovered that the system also has dual asteroid belts.

Featured Presentation
Where did we come from? Are we alone? Using infrared technology, NASA's Spitzer Space Telescope
will help answer these questions and more. Infrared telescopes allow us to study celestial
objects too hidden, too distant or too cool for us to see using other means.
These hidden worlds, once revealed, may give us clues to the origins of the universe.

"An Infrared Search for Origins".

The familiar winter sky constellation Orion takes on a spectacular guise in the infrared, as seen in this
false-color image constructed from data collected by
IRAS--the Infrared Astronomical Satellite.
New processing techniques have been used to enhance faint details and remove the instrumental artifacts
seen in earlier IRAS images.

Education Highlight
Our Sun has been steadily fusing hydrogen into helium for the last 5 billion years, and astronomers predict that it will
continue to do the same thing for another 5 billion years, until it runs out of hydrogen. But what happens then? Does the Sun just turn off?
