April Flowers for redOrbit.com - Your Universe Online Understanding weather patterns here on Earth is a complicated process, with scientists teasing apart different kinds of atmospheric movements, such as the great jet streams that can move across a whole hemisphere versus more localized, intricate flows, to create a whole picture. Those same methods and processes are used to understand the flows of the space weather system that links the Sun and the Earth as the Sun shoots material out...

Solar Winds Affect Earth's Magnetosphere

April Flowers for redOrbit.com — Your Universe Online Weather has always affected our lives, but we are increasingly reliant on technology that can be disrupted by space weather. Geomagnetic storms, which are major disturbances of the magnetosphere, cause high altitude flights to be rerouted, costing many thousands of dollars per flight; cause GPS errors of up to 151 feet; and affect the International Space Station and satellites. Geomagnetic storms and other space weather...

NASA -- A layer deep in the solar atmosphere can be used to estimate the speed of the solar wind, a stream of electrified gas that constantly blows from the Sun. Estimating the speed of the solar wind will improve space weather forecasts, enhancing our ability to protect communications, navigation, and other satellites from the effects of solar storms. We will also be able to warn human explorers on their way to the planets of the severity of those storms. The solar wind flows from the Sun's...

NASA spacecraft are monitoring an interstellar wind coming from the constellation Ophiuchus. Science@NASA -- Every year in early December, something happens that can throw your horoscope out of whack. The sun enters Ophiuchus, the little-known 13th house of the zodiac. You've probably heard of Capricorn, Aquarius, Pisces, Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio and Sagittarius. The sun passes through these constellations, one by one, throughout the year. They're the ancient...
