Scientists Pitch Massive Mirror Sun Shade to Save Earth

Mastermind convinced $350T project will get off ground in some 20 years

(Newser) - Scientists are proposing a stunning rescue project right out of a science fiction movie to save the earth from global warming: a massive 100,000-square-mile mirrored "sun shade." Trillions of tiny mirrors would be blasted by a cannon into space a million miles above earth to deflect the... More »

Massive Gamma Blast Spotted

Explosion had force of 9,000 supernovas

(Newser) - The strongest-ever gamma ray blast—a burst more powerful than 9,000 exploding stars—has been detected 12.2 billion light years away in deep space, reports the Telegraph. The blast took place in September in the constellation Carina, and produced energy up to 5 billion times that of light.... More »

Scientists Say Black Hole Lies at Center of Galaxy

Stars orbit around central nucleus 4M times heavier than sun

(Newser) - A giant black hole sits at the core of our galaxy, say astronomers who participated in a 16-year German study that monitored the movements of 28 stars circling the center of the Milky Way. “Beyond any reasonable doubt,” the stars orbit a core concentration of mass 4 million... More »
