BOULDER, Colo., Feb. 21, 2013 /PRNewswire-USNewswire/ -- Applying its atmospheric expertise to solar energy, the National Center for Atmospheric Research (NCAR) is spearheading a three-year, nationwide project to create unprecedented, 36-hour forecasts of incoming energy from the Sun for solar energy power plants. The research team is designing a prototype system to forecast sunlight and resulting power every 15 minutes over specific solar facilities, thereby enabling utilities to...

[Watch Video: Fiery Looping Rain On The Sun] Lee Rannals for redOrbit.com – Your Universe Online An eruption on the sun can be a beautiful, monstrous event, and NASA's Solar Dynamics Observatory (SDO) has helped to bring these dangerous, yet breathtaking events right to our computer screens. On July 19, 2012, the sun erupted in a solar flare, ejecting material called a coronal mass ejection (CME), creating a loop in the sun's atmosphere known as the corona. This moderately...

Michael Harper for redOrbit.com – Your Universe Online As it floats around the planet Saturn, the Cassini spacecraft recently got a front row seat to what NASA astronomers are calling an “unusual strong blast of solar wind.” Shortly after this “wind” blew by, Cassini began detecting particles which had been accelerated to ultra-high energies. Particles which are accelerated this much are usually found surrounding far away supernovas. This is good news for the Cassini team, as...

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 temperatures...

Lee Rannals for redOrbit.com - Your Universe Online For the first time, scientists from the international Cassini spacecraft have detected subatomic particles that have been accelerated to ultra-high energies in a blast of solar wind around Saturn, hinting at the possibility that the ringed planet may have experienced the aftermath of a supernova. According to a report by the European Space Agency (ESA) that appeared recently in the journal Nature Physics, this acceleration may be the...

Enid Burns for redOrbit.com – Your Universe Online The light that emanates from cities may be causing birds to mate earlier. That's according to a study conducted by Max Planck Institute for Ornithology in Radolfzell, Germany. The study found that nighttime light in urban areas causes birds and other animals to develop their reproductive systems earlier. In the study researchers at the Max Planck Institute studied European blackbirds (Turdus merula), to see how they develop in urban...

Lee Rannals for redOrbit.com – Your Universe Online A rare explosion from a rotating star may have created the most recent black hole formed in the Milky Way galaxy. Astronomers using NASA's Chandra X-ray Observatory claim that matter was ejected at high speeds along the poles of a rotating star, creating a supernova remnant, W49B, which may contain a young black hole. "W49B is the first of its kind to be discovered in the galaxy," said Laura Lopez, who led the study at the...

NASA [ Watch The Video ] On Feb. 11, 2010, NASA launched an unprecedented solar observatory into space. NASA's Solar Dynamics Observatory (SDO) flew up on an Atlas V rocket, carrying instruments that scientists hoped would revolutionize observations of the sun. If all went according to plan, SDO would provide incredibly high-resolution data of the entire solar disk almost as quickly as once a second. When the science team released its first images in April of 2010, SDO's data...
