Powering The SUn's Atmosphere
2013-11-15 09:30:08

John P. Millis, PhD for redOrbit.com - Your Universe Online The core of the Sun is a nuclear furnace, burning at 15 million degrees Kelvin. This heat travels to the surface, creating surface plasma that is still a balmy 6,000 Kelvin. However, a strange thing happens above the surface of the Sun; in the solar atmosphere, known as the corona, temperatures can exceed a million degrees Kelvin. Researchers have long suspected that the cause for this dramatic heating is due to interactions...

Sounding Rocket Getting Ready To Study Active Regions On The Sun
2013-08-03 07:59:17

NASA At NASA's White Sands Test Facility in Las Cruces, N.M., a sounding rocket is being readied for flight. Due to launch on Aug. 8, 2013, the VERIS rocket, short for Very high Resolution Imaging Spectrometer, will launch for a 15-minute trip carrying an instrument that can measure properties of the structures in the sun's upper atmosphere down to 145 miles across, some eight times clearer than any similar telescope currently in space. When it comes to observing the sun, different...

Solar Tsunami Measures Sun Magnetic Field
2013-07-11 12:19:51

Lee Rannals for redOrbit.com - Your Universe Online A solar tsunami has provided scientists with the first accurate estimates of the Sun's magnetic field. Researchers wrote in the journal Solar Physics that solar tsunamis are produced by enormous explosions in the Sun's atmosphere known as coronal mass ejections (CMEs). As these events move through space, the tsunami travels across the Sun at speeds of up to 621 miles per second. Solar tsunamis have a higher speed in regions where the...

Magnetic Waves Responsible For Keeping Sun's Corona Heated
2013-07-09 15:10:08

Lee Rannals for redOrbit.com - Your Universe Online Astronomers at the 44th meeting of the Solar Physics Division (SPD) of the American Astronomical Society are shedding light on the Sun's coronal heating mystery. The team found evidence magnetic waves in a polar coronal hole contain enough energy to heat the corona and deposit most of their energy at sufficiently low heights for the heat to spread throughout the corona. Their observations help answer a 60-year-old solar physics mystery...

NASA IRIS Launch Successful
2013-06-27 18:15:59

[ Watch the Video: IRIS Launch ] Lee Rannals for redOrbit.com – Your Universe Online NASA successfully launched its new Interface Region Imaging Spectrograph (IRIS) aboard an Orbital Sciences Pegasus XL rocket at approximately 7:27 pm (PST) tonight. IRIS and the Pegasus rocket were both flown aboard Orbital's Stargazer L-1011 commercial transport aircraft, which has been modified to serve as the launch platform. This launch design helps to keep the cost low for smaller missions,...

Whilst the most powerful earthquake since records began hit Japan in 2011, triggering a massive tsunami which devastated much of the country, space scientists involved in one of the 'brightest' international Sun missions continued working tirelessly at the Institute of Space and Astronautical Science in Sagamihara, Japan, to capture new data from our turbulent star. These latest Hinode results, to be discussed in a meeting at the University of St Andrews this week (Tuesday 14 August),...

Doppler Techniques Could Help Predict Solar Storms
2012-07-04 04:12:19

Lee Rannals for redOrbit.com - Your Universe Online Scientists are using Doppler techniques that may be able to take predicting space weather to a new level and understanding. An international team of researchers have combined Doppler techniques with images and data from a space-based telescope to observe loops of 1,800,000-degree Fahrenheit plasma flowing up from the sun's surface at more than 12 miles per second. These loops arch over the sun, and may be the first signs of trouble...

Images Of Extreme Solar Activity Provide Origins Of Powerful Space Storms
2012-07-02 09:58:45

Lawrence LeBlond for redOrbit.com - Your Universe Online An international team of scientists have for the first time captured and identified images of an upward surge of the Sun´s gases into quiescent coronal loops, a discovery that provides one more step in the understanding of the origins of extreme storms in outer space, which are known to wreak havoc on satellite systems and power grids here on Earth. University of Cambridge researchers worked with colleagues from the India and...

Hinode Will Capture Annular Solar Eclipse This Weekend
2012-05-18 03:39:13

On May 20-21, 2012 an annular eclipse of the Sun will be visible from within a narrow corridor along Earth's northern Hemisphere -- beginning in eastern Asia, crossing the North Pacific Ocean, and ending in the western United States. A partial eclipse will be visible from a much larger region covering East Asia, North Pacific, North America and Greenland. During an annular eclipse the moon does not block the entirety of the sun, but leaves a bright ring of light visible at the edges. For...

Hinode And SOHO Paint An Asymmetrical Picture Of The Sun
2012-04-23 04:36:24

Approximately every 11 years the magnetic field on the sun reverses completely — the north magnetic pole switches to south, and vice versa. It's as if a bar magnet slowly lost its magnetic field and regained it in the opposite direction, so the positive side becomes the negative side. But, of course, the sun is not a simple bar magnet and the causes of the switch, not to mention the complex tracery of moving magnetic fields throughout the eleven-year cycle, are not easy to map out....


Word of the Day
monteith
  • A large punch-bowl of the eighteenth century, usually of silver and with a movable rim, and decorated with flutings and a scalloped edge. It was also used for cooling and carrying wine-glasses.
  • A kind of cotton handkerchief having white spots on a colored ground, the spots being produced by a chemical which discharges the color.
This word is possibly named after Monteith (Monteigh), 'an eccentric 17th-century Scotsman who wore a cloak scalloped at the hem.'
