First analysis of Earth-sized planet's atmosphere reveals surprises

Using instrumentation aboard the Hubble Space Telescope, astronomers have been able for the first time to detect and analyze the atmospheric composition of a distant super-Earth (a planet roughly the size of our own). The findings show that the planet's atmosphere is rich in hydrogen, carbon and helium, giving scientists important clues as to how such planets might have formed and evolved.Read More

Unknown galaxies discovered lurking behind the Milky Way

In recent radio telescope studies, many hundreds of previously undiscovered galaxies have been found to exist in an area in which an enormous magnetic abnormality known as the "Great Attractor" is located. The new research may help shed light on why our galaxy, along with hundreds of thousands of others, is being inextricably pulled in that direction.Read More

Planet with 900,000-year orbit lies a staggering 1 trillion kilometers from its sun

In an astronomical astronomical discovery, scientists have identified what's believed to be the widest known planetary system. Situated about 104 light years from Earth, a planet that could be 15 times the size of Jupiter is in a 900,000-year orbit at a mind-boggling distance of 1 trillion km from its parent star – that's 7,000 times the distance of the Earth from the Sun.Read More

Is ET dead – and are we next?

With the number of potentially habitable exoplanets in our galaxy alone estimated to be in the billions, many wonder why we are yet to see signs or hear from intelligent alien life. A pair of astrobiologists from the Australian National University (ANU) Research School of Earth Sciences hypothesize the reason may be that ET could be long dead. According to Aditya Chopra and Charley Lineweaver, conditions on young planets are so volatile that if life doesn't evolve fast enough to stabilize the environment, it will quickly become extinct.Read More

World's largest connected radio telescope expands into Ireland

Ireland has been chosen as the site for latest expansion of the world's largest connected radio telescope. The Ireland-LOFAR consortium (I-LOFAR) has been awarded grants totaling €1.9 million (US$2 million) to extend the network for the International LOFAR Telescope (ILT), in hope of providing it with a resolution rivaling that of the Hubble Space Telescope.Read More

Dawn delivers its closest-ever view of Ceres

NASA's Dawn spacecraft has sent home the first images from its best-ever viewpoint around the dwarf planet Ceres, orbiting at an altitude of around 240 miles (385 km). The views include a chain of craters across the body's scarred surface, and two 3D snaps, viewable through red-blue glasses.Read More
