      Experiment Raises Hope of Solar Power From Space

      (Newser) - An experiment in beaming solar power has raised hopes that humanity can harness huge amounts of solar energy from satellites, Space.com reports. Researchers sent the energy about 90 miles between two Hawaiian islands via radio waves. The transmission of energy a hundred times further than earlier experiments proves the concept can work, said the former NASA scientist behind the test. One hurdle: Only a small fraction of the energy survived the transmission. More »

      Solar Lull May Trigger Ice Age

      (Newser) - Solar activity, which usually runs in 11-year cycles, has been so sluggish of late that space weathermen are worried we might be entering a mini-ice age. They expected to see sunspot activity pick up about last March, to peak in 2012; if the sun stays this sluggish for another year or two, it could trigger a prolonged period of massive snowfall and severe cold across the Northern Hemisphere, Popular Mechanics reports.

      Probe Zips Over Mercury Today

      (Newser) - NASA's Messenger spacecraft this afternoon will whiz past Mercury at 141,000 mph and snap an estimated 1,200 detailed photos of the planet's surface from a mere 124 miles up. It will be the first of three passes before the craft starts orbiting the planet closest to the sun in 2011. What scientists find could provide clues about how the Earth was formed. More »

      When the Sun Dies, Earth Might Not

      (Newser) - When the Sun begins to kick out in some 5 billion years, it might not take Earth with it, reports the New York Times. Scientists are more optimistic since discovering a planet that survived a similar situation. A lack of hydrogen fuel is expected to cause the Sun to expand 100-fold into a "red giant," enveloping Mercury and Venus and wiping out human life. More »

In a study aimed at testing the long-held theory that UV rays stimulate endorphins, researchers gave a group of sunbathers a drug blocking endorphin receptors The frequent tanners among them indeed presented symptoms of withdrawal.

      Most Massive Star Ever Weighs In

      (Newser) - The most massive star yet discovered has been "weighed," astronomers say, and it tips the scales at a whopping 114 times the mass of the sun. The enormous star forms the bigger half of a rapidly orbiting binary system and it far outstrips both its companion star and the previous record holder—which weigh in at 84 and 83 solar masses, respectively.
