Ultrafine Loops In The Sun's Corona
2012-06-13 15:31:07

A key to understanding the dynamics of the sun and what causes the great solar explosions there relies on deciphering how material, heat and energy swirl across the sun's surface and rise into the upper atmosphere, or corona. Tracking the constantly moving material requires state-of-the-art telescopes with the highest resolution possible. By combining images from NASA's Solar Dynamics Observatory (SDO) and a new generation telescope called the New Solar Telescope (NST) at Big Bear Solar...

ESA Contracts Astrium UK To Build Solar Orbiter
2012-04-27 03:18:20

ESA has awarded the contract to build its next-generation Sun explorer to Astrium UK. Solar Orbiter will investigate how the Sun creates and controls the heliosphere, the extended atmosphere of the Sun. Prof. Alvaro Giménez Cañete, ESA Director of Science and Robotic Exploration and Miranda Mills, National Director — Earth Observation, Navigation and Science of Astrium signed the contract on 26 April on the occasion of a ceremony celebrating 50 years of...

[ Watch the Video ] One day in the fall of 2011, Neil Sheeley, a solar scientist at the Naval Research Laboratory in Washington, D.C., did what he always does — look through the daily images of the sun from NASA's Solar Dynamics Observatory (SDO). But on this day he saw something he'd never noticed before: a pattern of cells with bright centers and dark boundaries occurring in the sun's atmosphere, the corona. These cells looked somewhat like a cell pattern that occurs on the...

RHESSI Mission Celebrates Ten Years And Forty Thousand X-Ray Flares
2012-02-11 04:00:56

[ Watch the Video ] On February 5, 2002, NASA launched what was then called the High Energy Solar Spectroscopic Imager (HESSI) into orbit. Renamed within months as the Ramaty High Energy Solar Spectroscopic Imager (RHESSI) after Reuven Ramaty, a deceased NASA scientist who had long championed the mission, the spacecraft's job was to observe giant explosions on the sun called solar flares. During a solar flare, the gas soars to over 20 million degrees Fahrenheit, and emits X-rays that...

Comet Survives Close Encounter With Our Sun
2011-12-18 06:18:30

[ Watch the Video ] On December 16, an armada of spacecraft witnessed something that many experts thought impossible.  Comet Lovejoy flew through the hot atmosphere of the sun and emerged intact. "It's absolutely astounding," says Karl Battams of the Naval Research Lab in Washington DC.  "I did not think the comet's icy core was big enough to survive plunging through the several million degree solar corona for close to an hour, but Comet Lovejoy is still with us." The...

First Comet Spotted By Ground-Based Telescope In Almost 40 Years
2011-12-14 11:19:11

[ Watch the Video ] Australian astronomer Terry Lovejoy spotted a Kreutz family comet by using a ground-based telescope for the first time since the 1970s. Lovejoy announced he discovered C/2011 W3, or comet Lovejoy, from the ground on December 2, 2011. NASA's Solar Heliophysics Observatory (SOHO) has spotted over 2100 comets, most of which are from the Kreutz family.  This family of comets graze the solar atmosphere where they usually evaporate completely. Discovering a...

Image 1 - Hinode's First Light And Five More Years
2011-11-01 12:55:16

On October 28, 2006, the Hinode solar mission was at last ready. The spacecraft launched on September 22, but such missions require a handful of diagnostics before the instruments can be turned on and collect what is called "first light." Hopes were high. Hinode had the potential to provide some of the highest resolution images of the sun the world had ever seen -- as well as help solve such mysteries as why the sun's atmosphere is a thousand times hotter than its surface and how the...

  Imagine forecasting a hurricane in Miami weeks before the storm was even a swirl of clouds off the coast of Africa–or predicting a tornado in Kansas from the flutter of a butterfly's wing(1) in Texas. These are the kind of forecasts meteorologists can only dream about. Could the dream come true? A new study by Stanford researchers suggests that such forecasts may one day be possible–not on Earth, but on the sun. "We have learned to detect sunspots before they are...

National Solar Observatory -- The National Solar Observatory (NSO) has its primary headquarters in Tucson. NSO telescopes on Kitt Peak include the McMath-Pierce Solar Telescope Facility containing the world's three largest solar telescopes (1.6-meter main and two 0.9-meter auxiliaries), along with the Vacuum Telescope and the Razdow small solar patrol telescope. The National Solar Observatory also operates telescopes at Sacramento Peak, New Mexico, that include the Vacuum Tower...

Kitt Peak Observatory -- astronomical observatory located southwest of Tucson, Ariz.; it was founded in 1958 under contract with the National Science Foundation and is administered by the Association of Universities for Research in Astronomy. Its principal instrument is the Mayall 158-in. (4-m) reflector. The observatory's equipment also includes 84-in. (2.1 m), 50-in. (1.3-m), 36-in. (0.9-m), and 16-in. (0.4-m) reflecting telescopes as well as a planned 3.5-m telescope. Used for wide...

  • 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.'
