A supernova (pl. supernovae) is a stellar explosion. Supernovae are extremely luminous and cause a burst of radiation that often briefly outshines an entire galaxy, before fading from view over several weeks or months. During this short interval, a supernova can radiate as much energy as the Sun could emit over its entire life span.[1] The explosion expels much or all of a star's material[2] at a velocity of up to 30000 km/s (a tenth the speed of light), driving a shock wave[3] into the surrounding interstellar medium. This shock wave sweeps up an expanding shell of gas and dust called a supernova remnant.

to oxygen and nutrients, they grow, reproduce, organise to form colonies and contain the master molecules of life - DNA. Their ability to survive extremes of radiation, temperature and pressure, make them perfect space travellers and are the most convincing evidence yet of an extraterrestrial life form.

A Window On The Universe

. From its vantage point 600 km above the Earth, Hubble can detect light with "eyes" five times sharper than the best ground-based telescopes and looks deep into space where some of the most profound mysteries are still buried in the mists of time. Hubble European Space Agency Information Centre Garching/Munich, Germany • www.eso.org • http • hubblesite.org Dr. J is a German astronomer at the ESO. His scientific interests are in cosmology, particularly on galaxy evolution and quasars. Dr. ...

resolution images of planets and moons in our own Solar System, it has also taught us a lot about our own cosmic neighbourhood. Hubble cannot observe our Sun, or the closest planet, Mercury, because its instruments are light-sensitive and would be damaged. However, the telescope has examined every other planet in the solar system, including dwarf planets Pluto, Ceres and Eris. But, of course, Hubble does not just produce pretty pictures, it provides planetary scientists with vital ...

History Channel The Universe Space Travel. When man finally broke free of the Earth's gravitational pull the dream of traveling to other planets became a reality. Today scientists are proposing a bizarre array of technologies in the hope of traveling faster through space: from space craft sporting sails that catch laser beams, to propulsion engines powered by a bizarre entity known as anti-matter. Finally explore the science behind the seemingly fanciful notion of warp-drive and a ...
