Today, NASA-funded researchers released to the general public a new "4D" live model of Earth's ionosphere. Without leaving home, anyone can fly through the layer of ionized gas that encircles Earth at the edge of space itself. All that's required is a connection to the Internet. "This is an exciting development," says solar physicist Lika Guhathakurta of NASA headquarters in Washington, DC. "The ionosphere is important to pilots, ham radio operators, earth scientists and even soldiers. Using...

Scientists are now testing a new method that uses SOHO data to predict, in real-time, the approach and intensity of hazardous solar particles that would threaten astronauts and technology in space. The method was developed eight months ago by Dr Arik Posner, Southwest Research Institute (SwRI), USA, with collaborators from the University of Kiel in Germany, NASA's Goddard Space Flight Center, USA and the University of Turku in Finland. It shows how latest results from basic solar physics...

A new 11-year cycle of heightened solar activity, bringing with it increased risks for power grids, critical military, civilian and airline communications, GPS signals and even cell phones and ATM transactions, showed signs it was on its way late Thursday when the cycle's first sunspot appeared in the sun's Northern Hemisphere, NOAA scientists said. "This sunspot is like the first robin of spring," said solar physicist Douglas Biesecker of NOAA's Space Weather Prediction Center. "In this...

If a satellite encounters high-energy particles or other 'space weather' phenomena before ground controllers can take action, on-board electronics could be disrupted, scientific instruments damaged and, in very rare and extreme cases, spacecraft may even be lost. A sophisticated tool in development at ESOC promises to provide effective monitoring and forecasting for any type of mission. But since early 2005, SEISOP (Space Environment Information System for Operations), a space-weather...

WASHINGTON (AP) -- A large solar flare was reported Wednesday and forecasters warned of potential electrical and communications disruptions. The flare was reported by the National Oceanic and Atmospheric Administration's Space Environment Center in Boulder, Colo. Significant solar eruptions are possible in the coming days and there could be disruptions in spacecraft operations, electric power systems, high frequency communications and low-frequency navigation systems, the agency said....

A breakthrough by a team of British, US and French scientists will help protect astronauts, spacecraft and satellites from radiation hazards experienced in space. Reporting in the journal Nature this week, the team describe how their study of rare and unusual space storms provided a unique opportunity to test conflicting theories about the behaviour of high energy particles in the Van Allen radiation belts* - a volatile region 12000 miles (19,000 km) above the Earth. Lead author, Dr Richard...

NOAA -- Forecasters at the NOAA Space Environment Center in Boulder, Colo., observed a geomagnetic storm on Sunday, May 15, which they classified as an extreme event, measuring G-5"”the highest level"”on the NOAA Space Weather Scales. "This event registered a 9 on the K-Index, which measures the maximum deviation of the Earth's magnetic field in a given three-hour period," said Gayle Nelson, lead operations specialist at NOAA Space Environment Center. "The scale ranges from 0 to...

The biggest solar proton storm in 15 years erupted last week. NASA researchers discuss what it might have done to someone on the Moon. Science@NASA -- NASA is returning to the Moon -- not just robots, but people. In the decades ahead we can expect to see habitats, greenhouses and power stations up there. Astronauts will be out among the moondust and craters, exploring, prospecting, building. Last week, though, there were no humans walking around on the Moon. Good thing. On January 20th,...

Word of the Day
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
