Ancient sea mud records supernova blast
(Nov 4, 2007)
It is the oldest telescope in the world – and it lies at the
bottom of the ocean. Ancient sea floor sediments have revealed that
a supernova exploded
during the Pliocene
era and may have caused a minor extinction event on Earth.

Astronaut fixes torn solar panel
(Nov 3, 2007)
A US astronaut has carried out a dangerous spacewalk to fix a damaged
solar panel on the International
Space Station (ISS). The energy-collecting wing developed a rip
when it was being unfurled at the port end of the platform on Tuesday.
Scott Parazynski rode on the end of an extension boom to install home-made
"cufflinks" to the broken section.

Earth-like planets get life assessment
(Nov 3, 2007)
The most Earth-like planet discovered so far is not quite in the right
place to be habitable after all, researchers say. But its neighbour
might be. Discovered in April, the planet Gliese
581c caused a lot of initial excitement.

Prime landing sites chosen for biggest
Martian rover
(Nov 3, 2007)
Half a dozen possible landing sites have been selected for NASA's
Mars Science
Laboratory (MSL), due to launch late in 2009. The rover, the largest
ever to travel to Mars, will try to find out whether the Red Planet
was once conducive to life. The rover should touch down on Mars in
October 2010.

Vast amount of water ice may lie on Martian
equator
(Nov 2, 2007)
Some puzzling land formations on Mars's
equator could be huge glacier-like deposits of frozen water, new radar
observations suggest. The material's radar properties might be explained
by unusually porous rocky material instead, but if it is water it
would represent a huge amount – as much as a polar ice cap contains,
providing a potential water source for future human explorers.

Giant telescope's double vision
(Nov 1, 2007)
Almost 20 years after it was first conceived, what will become the
world's most powerful optical telescope is about to open its eyes.
Lying beneath the clear skies of Arizona, the $120m (£55m) Large
Binocular Telescope will allow astronomers to probe the Universe
further back in time and in more detail than ever before.

Reaching for the stars and planets
(Nov 1, 2007)
Scientists from Queen's University in Belfast have found three new
planets orbiting their own stars. The new discoveries have been named
Wasp-1, 2 and 3 respectively. They are all gas
giants similar to our Jupiter. Using equipment they built themselves,
the scientists from the University's Astrophysics Research Centre
have been observing hundreds of thousands of stars for several months.
