IRIS Spotted Its Largest Solar Flare In January
2014-02-22 05:28:40

[ Watch the Video: IRIS Spots Its Largest Solar Flare ] April Flowers for redOrbit.com - Your Universe Online The strongest solar flare since NASA's Interface Region Imaging Spectrograph (IRIS) launched in the summer of 2013 was observed on January 28 of this year. Solar flares are bursts of X-rays and light that stream out into space, disrupting long-range radio transmission on Earth and satellite functions in space. What sets them off, however, is still a mystery for scientists....

Sun's Chromosphere Studied By Sunrise Mission
2013-09-28 04:29:37

April Flowers for redOrbit.com - Your Universe Online In June 2013, the solar observatory Sunrise was carried aloft by a NASA scientific balloon. Three months later, scientists from the Max Planck Institute for Solar System Research in Germany have presented unique insights into a layer on the sun called the chromosphere. The images from Sunrise are the highest-resolution ultraviolet light images to date of this thin corrugated layer, which lies between the sun's visible surface and the...

Alpha Centauri B May Shed Light On Our Own Sun’s Anomalies

Michael Harper for redOrbit.com — Your Universe Online As it turns out, studying our Sun can be rather difficult. It´s not the distance so much that keeps scientists guessing — although that certainly doesn´t help. The Sun´s intense heat also keeps scientists at bay, leaving them to make some of their observations and predictions based purely on context and far away measurements. One thing astronomers have been able to observe is a significant difference in...

Sun Surface Cooler Than Previously Thought

Lee Rannals for redOrbit.com — Your Universe Online One who didn't know better would think that the closer you get to the sun, the warmer you are. However, it is actually the outer edge of the sun that you would find to be scorching, compared to the surface, and one study sought to find out why. Scientists from Northumbria University wrote in the journal Nature Communications that they used solar-imaging technology to observe the Sun's chromosphere, which is a region of the Sun's...

NASA Launching New Sun Observing Spacecraft Thursday
2012-07-04 13:04:55

Lee Rannals for redOrbit.com - Your Universe Online While the nation shoots off plenty of fireworks for the Fourth of July, NASA will be sending off its own rocket the next day. The space agency will be launching its Solar Ultraviolet Magnetograph Investigation (SUMI) on Thursday to study the magnetic fields on the sun. SUMI will set out to study the constantly changing magnetic fields in an area of the sun's low atmosphere called the chromosphere. These magnetic fields lie at the...

New satellite imagery of the sun is providing scientists with clues to understanding the long-standing mystery of what is heating up the solar corona The 2006 launch of the multinational Hinode satellite changed the picture of the sun for astrophysicists. For two astrophysicists in particular, the resulting imagery offered a voyage of discovery and the thrill of unraveling a long-held solar mystery. The Earth's atmosphere can obscure the view of unaided ground-based telescopes, but,...

Research explains century-old mystery about the interior of the sun Sound waves escaping the sun's interior create fountains of hot gas that shape and power a thin region of the sun's atmosphere which appears as a ruby red "ring of fire" around the moon during a total solar eclipse, according to research funded by the National Science Foundation (NSF) and NASA. The results are presented today at the American Astronomical Society's Solar Physics Division meeting in Hawaii. This region, called...

Chromosphere -- The chromosphere (literally, "color sphere") is a thin layer of the Sun's atmosphere just above the photosphere, roughly 10,000 kilometers deep. The chromosphere is more visually transparent than the photosphere. The most common solar feature within the chromosphere are spicules, long thin fingers of luminous gas which appear like the blades of a huge field of fiery grass growing upwards from the photosphere below. Spicules rise to the top of the chromosphere and then sink...

Solar Flare -- A solar flare is a violent eruption that explodes from a star's photosphere with energies equivalent to tens of millions of hydrogen bombs. Solar flares from the Sun send out a streams of highly energetic solar wind that can present a radiation hazard to spacecraft outside of planetary magnetospheres and can disrupt radio signals on Earth. Solar flares were first observed on the Sun in 1859 by English astronomer Richard Carrington. They have also been observed to...

The Sun -- intensely hot, self-luminous body of gases at the center of the solar system. Its gravitational attraction maintains the planets, comets, and other bodies of the solar system in their orbits. The sun is actually a star of about medium size; it appears larger than the other stars because of its relative nearness to the earth. The earth's distance from the sun varies from 91,377,000 mi (147,053,000 km) at perihelion to 94,537,000 mi (152,138,000 km) at aphelion (see apsis). The...

Word of the Day
mallemaroking
  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
