G350.1-0.3 is a young and exceptionally bright supernova remnant about 15,000 light years from Earth. Its unusual shape suggests that the debris from the supernova explosion is expanding into a nearby cloud of cold gas. - Credit: NASA/JPL-Caltech
Watch a 'post-mortem' of a star explosion - Supernova- In February 1987, astronomers saw a new point of light appear in the sky: a supernova explosion, roughly 150,000 light-years from Earth. A massive star had reached the end of its fuel supply & gone down in a blaze of glory. Since then, scientists have studied the corpse of Supernova 1987A extensively, including visualizing the supernova's dissection in a new video.
As many as nine out of 10 of the world's seabirds likely have pieces of plastic in their guts, a new study estimates. Previously, scientists figured about 29 percent of seabirds had swallowed plastic, based on older studies. An Australian team of scientists who have studied birds and marine debris for decades used computer models to update those figures, calculating that far more seabirds are affected, according to a new study published Monday in...
NASA - Dissecting the Scene of Sky Crane Crash The main crash site is seen at right, shaped like a fan. Farther from the site are several smaller dark spots, which are thought to be secondary impacts from debris that continued to travel outward. The impact sites are darker because the lighter, reddish top layer of soil was disturbed, revealing darker basaltic sands underneath.
