New free software for home computers based on an algorithm created through NASA’s Asteroid Grand Challenge has the potential to increase the number of new asteroid discoveries by enabling amateur astronomers to analyse their own images.
The Hapi region of 67P is located between the comet’s two lobes and has proven to be particularly active, displaying a bluish reflectivity spectrum in colour images captured with Rosetta’s OSIRIS camera. This strongly suggests that frozen water is mixed with the dust at the surface.
Our complete guide to observing Friday’s large partial eclipse. Find out how observers across the UK and Europe can witness this large partial eclipse in safety.
Jupiter’s moon Ganymede is the largest moon in our Solar System and the only moon with its own magnetic field. NASA’s Hubble Space Telescope has the best evidence yet for a 60-mile deep underground saline ocean on Ganymede, believed to contain more water than all the water on Earth’s surface.
New research indicates that the Milky Way may be 50 percent larger than previously believed. Furthermore, the Galaxy’s shape is not just a flattened spiral, but contoured into several concentric ripples.
Our Managing Editor, Steven Young, travelled with Explorers Astronomy Tours to Australia in the hope that the clouds parted for long enough to see the total solar eclipse of November 2012.
NASA’s Cassini spacecraft finds the first evidence of active hot-water chemistry beyond planet Earth on Saturn’s ocean moon Enceladus — results that have important implications for the habitability of icy worlds.
On March 11th at 4:22 pm GMT, the Sun emitted a powerful solar flare that registered 2.2 on the X-class scale. NASA’s Solar Dynamics Observatory captured the event in stunning detail.
Astronomers have discovered a ‘treasure trove’ of rare dwarf satellite galaxies orbiting our own Milky Way. The closest is about 95,000 light-years away, while the most distant is more than a million light-years away.
