Astronomers may have found solar system's first observed interstellar object

Science
Oct. 28 (UPI) -- Astronomers are tracking what they believe may be the first observed interstellar asteroid or comet to travel through Earth's solar system, NASA said.The space agency said the object is less than a quarter mile in diameter and is traveling "remarkably fast." They're not sure what exactly it is.Paul Chodas, manager of NASA's Center for Near-Earth Object Studies, said the agency has been "waiting for this day for decades.""It's long been theorized that such objects exist -- asteroids or comets moving around between the stars and occasionally passing through our solar system -- but this is the first such detection. So far, everything indicates this is likely an interstellar object, but more data would help to confirm it," he added.The University of Hawaii's Pan-STARRS 1 teles...

Drones, solar and apps: It's not your father's sector rotation anymore

Finance
Many individual investors fail to manage their equity portfolios with an awareness of "sector rotation" — ups and downs in different sectors' performance, stemming from changing economic conditions and inevitable shifts in market favor.Historically, determining which sectors were likely to do well at a given time was basically a function of the economy. Different sectors tended to perform well at different points in the economic growth cycle, from recession to expansion and then back down again, affected variously by such factors as commodity prices, the broad state of corporate earnings, interest-rate shifts and consumer confidence.Some of this wisdom may still apply, but things are much different now, especially regarding consumer sectors. As relentless technological advances change cons

Australia's solar challenge begins

Science
The rules of the race are quite precise. "Based on the original notion that a 1000W car would complete the journey in 50 hours, solar cars are allowed a nominal 5kW hours of stored energy, which is 10% of that theoretical figure. All other energy must come from the sun or be recovered from the kinetic energy of the vehicle," the organisers say.Let's block ads! (Why?) BBC News - Science & Environment
Scientists propose space shield to protect Earth from solar storms

Scientists propose space shield to protect Earth from solar storms

Science
Oct. 6 (UPI) -- If governments and their space agencies are serious about protecting Earth from solar storms, one team of researchers argues a giant space shield is the most logical solution.Much attention is paid to the threat of comets and asteroids. In the past, violent collisions have triggered mass extinctions. Solar storms -- intense waves of high energy particles flung into space during coronal mass ejection -- aren't so much a threat to life. But they could seriously damage satellites, electric grids, communications systems and a variety of modern technologies.When a massive geomagnetic solar storm struck Earth in 1859, the only observable effect was a spate of vibrant auroras. If a similarly powerful storm hit Earth today, the global economy could suffer losses totaling in the tri...
French company Total steps into solar energy market

French company Total steps into solar energy market

Business
Sept. 19 (UPI) -- In an announcement ahead of the French president's speech before the U.N. General Assembly, Total said it took a greater stake in a renewable power company.The French supermajor said Tuesday it made a $ 284.7 million investment to take an indirect 23 percent stake in renewable power company EREN RE. Total said could eventually take the company over completely within the next five years."EREN RE's momentum will allow us to accelerate our growth in solar energy and move us into the wind power market," Philippe Sauquet, the president in charge of gas, renewables and power for Total, said in a statement. "The agreement with EREN RE is a major step towards our objective of achieving 5 gigawatts of installed [renewable energy] capacity in five years."The French company is comin...
