Jupiter’s Great Red Spot is a swirling anticyclonic storm that was previously large enough to fit three Earths inside.  However, observations taken by the NASA/ESA Hubble Space Telescope has revealed that this is changing, both in shape and size. So why is Jupiter’s trademark feature beginning to downsize? The Great Red Spot was once an oval shape but now is quite circular and measures just under 16,500 kilometers (10,253 miles) across.  This is much smaller than what it used

Many stars end their existence by going out in a huge explosion known as a supernova. However, only a few of these stellar explosions have been caught in the act. When they are, spotting them successfully has been down to pure luck—until now. On 11 December 2015 astronomers not only imaged a supernova in action, but saw it when and where they had predicted it would be. The supernova, nicknamed Refsdal, has been spotted in the galaxy cluster MACS J1149.5+2223. The light from t

This week NASA is celebrating a quarter century of discoveries from one of the most revolutionary scientific instruments of all time, the Hubble Space Telescope. Launched into orbit aboard the Space Shuttle Discovery on April 25, 1990, the Hubble changed our understanding of the age of the universe, the evolution of galaxies and the expansion of space itself. Along the way it has had the equivalent of knee and hip replacement surgery: Five times, astronauts on the space shutt

NASA’s Dawn spacecraft has traveled roughly 3 billion miles at this point and it’s finally set its sights on the dwarf planet Ceres.  Images of Ceres were released back in December, but those images were just for calibration.  Dawn’s recently captured pictures are about 27 pixels across, about three times better than what it took last month. This image, taken Tuesday, is enhanced from its original size.  The photo was taken some 238,000 miles away — about the distance from th
