Image credit: Hubble The Hubble Space Telescope has used a natural 2-million-light-year wide “zoom lens” to look further into space than it normally could. By peering directly through the centre of one of the most massive galactic clusters known, it was able to take advantage of a technique called gravitational lensing to see objects beyond …

Image credit: NASA A team of French and American astronomers have discovered the presence of salt (NaCl) in Io’s atmosphere. They think that the salt was ejected into the Jovian moon’s atmosphere by the many volcanos that ceaselessly bubble across its surface. The atmosphere of Io has been studied for several years now, first observed …
Image credit: NASA A team of astronomers have taken the highest resolution mid-infrared picture ever taken of the center of our Milky Way galaxy. The image is so detailed, you can actually see dust swirling around the giant black hole located at the centre of the galaxy. The camera, called the Mid-Infrared Large-Well Imager, or …

Image credit: NASA NASA announced today that it has awarded an $825 million contract to aerospace firm TRW to build the replacement for the Hubble Space Telescope: The James Webb Space Telescope. Named for NASA’s second administrator, this new observatory will launch in 2010 and operate 1.5 million km away from the Earth (Hubble is …

Image credit: ESO The latest image released from the European Southern Observatory is of the Tarantula Nebula, located in the Large Magellanic Cloud approximately 170,000 light years from here. The nebula measures more than 1,000 light years across and covers the same amount of sky as the Moon. The image is a composite made up …
Image credit: NASA A team of astronomers from the Space believe that red quasars may be more common in the Universe than previously thought. Quasars are bright, distant objects and the current theory is that they are caused by the black holes that reside at the centre of galaxies – because they’re so hot, they …
Image credit: ESA Some scientists have theorized that life on Earth began when amino acids, the building blocks of life, were delivered from space by comets and asteroids. The European Space Agency is planning two missions to help gather more evidence. Rosetta, due for launch in 2003, will study the composition of gas and dust …
Image credit: 2MASS One of the most groundbreaking work in astronomy being done right now is the Two Micron All-Sky Survey which is producing a high-resolution survey of the entire sky in the Infrared spectrum. Two telescopes, one in Arizona, the other in Cerro Tololo, Chile have been working non-stop for 4 years to take …
Image credit: NASA A team of astronomers from UCLA have found cloudy, stormy atmospheres on brown dwarfs – objects larger than gas giants like Jupiter, but not large enough to ignite into full stars. They believe the discovery of these storms could provide insights into some strange observations of brown dwarfs. Instead of steadily cooling, …
Image credit: Gemini Thanks to the adaptive optics system of the Gemini observatory, astronomers have been able to spot a brown dwarf orbiting a star only three times the distance of the Earth to the Sun. This newly discovered pair, LHS 2397a, is located only 46 light years from Earth and is the closest separation …
