The discovery of more than 330 planets outside our solar system in recent years has helped refine the number of life forms that are likely to exist. The current research estimates that there are at least 361 intelligent civilisations in our Galaxy and possibly as many as 38,000.
It is enchanting, spectacular and - at 3.5m in diameter - it will soon become the biggest telescope mirror in space, surpassing that of Hubble.... It will take up a vantage point a million-and-a-half kilometres from Earth, to open up what scientists expect to be an utterly fascinating new vista on the Universe. Unlike Hubble, which is tuned to see the cosmos in the same light that is visible to our eyes, Herschel will go after much longer...

astronomyThe Thermal Emission Imaging System (THEMIS) is an instrument on board the Mars Odyssey spacecraft. It combines a 5-wavelength visual imaging system with a 9-wavelength infrared imaging system. The orbiter launched from Kennedy Space Center on April 7, 2001 and arrived at Mars on October 24, 2001.
The first stage of the switch-on of one of the world's most powerful stargazing systems has got under way. Seven radio telescopes around the UK have been linked with optical fibres, allowing scientists to probe deeper into the Universe than ever before. The new data-link upgrade has replaced the older microwave technology that once connected the telescopes.
