Berkeley scientists this week discovered a new supernova, closer to Earth than any seen in the last 40 years, and believe they've spotted it within hours of its explosion. Astronomers are now scrambling to observe it with as many telescopes as possible, including the Hubble Space Telescope, and it's likely to remain a major target for research for the next decade or more. Dubbed PTF 11kly, the supernova is about 21 million light-years away in the Pinwheel Galaxy, in the Ursa Major constellation. It was discovered by the Palomar Transient Factory (PTF) survey, which uses a robotic telescope mounted on the 48-inch Samuel Oschin Telescope to scan the sky nightly.

SpaceX Dragon approaches the ISS on COTS 2 test flight slated for May 19 liftoff and docking on Day 4. Astronauts will grapple it with the robotic arm and berth it at the Earth facing port of the Harmony node. Illustration: NASA /SpaceX In less than 48 hours, SpaceX is primed to make history and launch the first ever commercial rocket and spacecraft to the International Space Station (ISS) early Saturday morning on May 19. Following today’s Launch Readiness Review (LRR), SpaceX was just given the official “GO” from NASA to proceed with the blastoff of the Falcon 9 at 4:55 a.m. EDT (0855 GMT) from Space Launch Complex-40 on Cape Canaveral Air Force Station in Florida.SOLAR STORM HEATS UP EARTH'S ATMOSPHERE: A flurry of solar activity in early March dumped enough heat in Earth's upper atmosphere to power every residence in New York City for two years. The heat has since dissipated, but there's more to come as the solar cycle intensifies.

New date: On Sunday, March 25th, between midnight and 3 am EDT, NASA plans a rapid-fire launch of five sounding rockets from Wallops. The rockets will deliver a chemical tracer to the upper reaches of Earth's atmosphere, forming milky white plumes that reveal high-speed winds at the edge of space. The display should be visible to the naked eye from coastal areas between South Carolina and New Jersey. [ full story ] [ updates ]
