The NASA/ESA Hubble Space Telescope has captured the image of the first-ever predicted supernova explosion. The reappearance of the Refsdal supernova was calculated from different models of the galaxy cluster whose immense gravity is warping the supernova’s light.
April 6, 2009--A new x-ray image has revealed an unusual hand-shaped nebula that brings a whole new meaning to the expression "reach for the stars." Known as B1509, the pulsar is thought to be about 1,700 years old and lies roughly 17,000 light-years from Earth. The tiny pulsar is just 12 miles (19.3 kilometers) wide. But it is spinning so fast—it makes seven complete rotations every second—that the particles it spews have created a nebula spanning 150 light-years.
Ash, magma and lightning during an eruption of the Sakurajima volcano in southern Japan that occurred in early January Why lightning occurs in thunderstorms is a topic of research; why it occurs in volcanic eruptions is even less understood.
Picture This: Hurricanes and Wildfires from Space- Winds and fire wrought havoc this week as wildfires exploded in Northern California and Hurricane Odile became the most powerful storm to strike Baja California. The devastation of both events was caught in poignant and impactful photos. But other images captured more peaceful tableaus, including the beauty of landscapes erupting in a riot of autumnal color.
Guts of Exploded Star Revealed -- A team of astronomers led by the University of Colorado at Boulder are charting the interactions between Supernova 1987A and a glowing gas ring encircling the supernova remnant known as the "String of Pearls."
