SUN'S corona COULD BE HOT BECAUSE OF FRICTION

Recent observations made by NASA's Transition Region and Coronal

Explorer (TRACE) spacecraft have shown that the sun's outer

atmosphere, called the corona, causes friction on gas that

erupts from the surface - friction hundreds of millions of

times more powerful than previously expected. This friction

could be the reason the corona is 100 times hotter than the

surface of the sun.

IO'S ATMOSPHERE A SPARKLING AURORAL light SHOW

Images of Io taken by Galileo while the Moon passed through

Jupiter's shadow have shown the moon's atmosphere produces colourful

auroral emissions - similar to the northern lights on Earth. It's

suspected that the aurorae are produced by a combination of powerful

electric currents and volcanic plumes.

NASA BUDGET CUTS DELAYED

The House has decided to postpone a vote until September which could

deliver a set of devastating cuts to NASA's budget. If the vote goes

through, NASA's budget would be cut by almost $1 billion, which NASA

administrator Dan Goldin feels would devastate the agency.
