NASA — Did comet Ison survive its trip around the sun? After several days of continued observations, scientists continue to work to determine and to understand the fate of Comet ISON: There’s no doubt that the comet shrank in size considerably as it rounded the sun and there’s no doubt that something made it out […]

Circadian Rhythms
National Institute of General Medical Sciences — What are circadian rhythms? Circadian rhythms are physical, mental and behavioral changes that follow a roughly 24-hour cycle, responding primarily to light and darkness in an organism’s environment. They are found in most living things, including animals, plants and many tiny microbes. The study of circadian rhythms is […]

Magnetic Field of the Sun to Flip
Something big is about to happen on the sun. According to measurements from NASA-supported observatories, the sun’s vast magnetic field is about to flip. “It looks like we’re no more than 3 to 4 months away from a complete field reversal,” says solar physicist Todd Hoeksema of Stanford University. “This change will have ripple effects […]
Solar Radiation Storms
Solar radiation storms continue. It takes about two days for the effects to reach Earth. A solar flare is a sudden brightening observed over the Sun’s surface or the solar limb, which is interpreted as a large energy release of up to 6 × 1025 joules of energy (about a sixth of the total energy […]
Solar Storms
G1 (Minor) storming is expected on March 16th and G2 (Moderate) geomagnetic storming is expected on the 17th from this morning’s coronal mass ejection. The CME is the bright loop leaving the Sun to the upper left of the circular center in the image below (Image Credit ESA/NASA SOHO LASCO).

Sweet Find: Space Sugar Discovered
NASA — The prospects for life in the Universe just got sweeter, with the first discovery of a simple sugar molecule in space. The discovery of glycolaldehyde in a giant cloud of gas and dust near the center of our own Milky Way Galaxy was made by scientists using the National Science Foundation’s 12 Meter […]

Geomagnetic Storm Watch
As the strongest Solar Radiation Storm (S3) since May, 2005 continues, the associated Earthward-directed Coronal Mass Ejection is expected to arrive about 1400 UT (9am EST) Jan 24. SWPC has issued a Geomagnetic Storm Watch with G2 level storming likely and G3 level storming possible, with the storm continuing into Wednesday, Jan 25. All of […]
