  • The Axion of the Quark Gluon Pasma?

    In physics, an anomalon is a hypothetical type of nuclear matter that shows an anomalously large reactive cross section. They were first noticed in experimental runs in the early 1980s as short tracks in film emulsions or plastic leaf detectors connected to medium-energy particle accelerators. The direction of the tracks demonstrated that they were the…

  • IRIS(Interface Region Imaging Spectrograph) and the Latest

    Interface Region Imaging Spectrograph (IRIS) Graphic of proposed IRIS spacecraft. The IRIS instrument is a multi-channel imaging spectrograph with a 20 cm UV telescope. IRIS will obtain spectra along a slit (1/3 arcsec wide), and slit-jaw images. Credit: NASA The Interface Region Imaging Spectrograph (IRIS) is a NASA solar observation satellite. The mission was funded…

  • The Sun

    24 July 2014 – Mission Day: 6810 – DOY: 205 “Courtesy of NASA/SDO and the AIA, EVE, and HMI science teams.” *** Spun and Confused Published on Jul 21, 2014 A long arch of plasma (called a prominence) was pulled this way and that by magnetic forces for a week before it finally dissipated (July…

  • NASA | First X-Class Solar Flares of 2013

    Published on May 13, 2013 On May 12-13 the sun erupted with an X1.7-class and an X2.8-class flare as well as two coronal mass ejections, or CMEs, off the upper left side of the sun. Solar material also danced and blew off the sun in what’s called a prominence eruption, both in that spot and…

  • Iris-Interface Region Imaging Spectrograph

    This graphic shows the IRIS observatory with the solar arrays removed. The orange section to the left is the spacecraft bus which includes the spacecraft support structure, the command and data handling system, power distribution system, reaction wheels, X- and S-Band communications systems, Li-Ion battery, magnetic torque rods, and electronics for the sun sensors. The…

  • Latest SDO IMage

    This image taken by SDO’s AIA instrument at 171 Angstrom shows the current conditions of the quiet corona and upper transition region of the Sun. Active Region 1515 released an M6.9 class flare beginning at 12:23 PM EDT and peaking at 12:32 on July 7, 2012. This region has been the source of much solar…

  • SOHO Latest and Space Weather

    EIT 304 A large solar flare yesterday triggered a coronal mass ejection travelling at 1400 km/s that will reach Earth today. An energetic eruption of this level can disrupt satellites, so operation teams at ESA and other organisations are closely monitoring the storm. A coronal mass ejection (CME) is a huge cloud of magnetised plasma…

  • Comet LoveJoy

    Comet Lovejoy seen by SOHO “On average, new Kreutz-group comets are discovered every few days by SOHO, but from the ground they are much rarer to see or discover,” says Karl Battams, Naval Research Laboratory, who curates the Sun-grazing comets webpage. See Also: The beginning of the end for comet Lovejoy  One instrument watching for…

  • Solar Dynamics Observatory Pick of the Week

    (Click on Image for Larger Veiwing) Then and Now A side-by-side comparison of the Sun from precisely two years ago (left, from SOHO) to the present (right, from Solar Dynamics Observatory) dramatically illustrates just how active the Sun has become (Mar. 27-28, 2011). Viewed in two similar wavelengths of extreme ultraviolet light, the Sun now…
