Classic portrait of a barred spiral galaxy
The NASA/ESA Hubble Space Telescope has taken a picture of the barred spiral galaxy NGC 1073, which is found in the constellation of Cetus (The Sea Monster). Our own galaxy, the Milky Way, is a similar barred spiral, and the study of galaxies such as NGC 1073 helps astronomers learn more about our celestial home.

Surface of Mars an unlikely place for life after 600-million-year drought, say scientists
Mars may have been arid for more than 600 million years, making it too hostile for any life to survive on the planet?s surface, according to researchers who have been carrying out the painstaking task of analyzing individual particles of Martian soil.

Alien Comets Invade the Solar System

Some of the comets in our Solar System probably came from other stars, according to new research by NASA-supported scientists. Studying these 'alien' comets, they say, could reveal new information about stellar systems far, far away.

Surface of Mars an unlikely place for life after 600 million year drought, say scientists
Mars may have been arid for more than 600 million years, making it too hostile for any life to survive on the planet's surface, according to researchers who have been carrying out the painstaking task of analysing individual particles of Martian soil. Dr Tom Pike, from Imperial College London, will discuss the team's analysis at a European Space Agency (ESA) meeting on February 7, 2012. The researchers have spent three years analysing data on Martian soil that was collected during the 2008 NASA Phoenix mission to Mars. Phoenix touched down in the northern arctic region of the planet to search for signs that it was habitable and to analyse ice and soil on the surface.
