Latest Corona Stories
Reconnaissance photos captured by Cold War-era spy satellites have tripled the number of known archaeological sites located throughout the Middle East, the creators of a new atlas revealed Thursday at the Society for American Archaeology's annual conference.
Like a balloon bobbing along in the air while tied to a child's hand, a tracer has been found in the sun's atmosphere to help track the flow of material coursing underneath the sun's surface.
Video of magnetic field lines 'slipping reconnection' bring scientists a step closer to predicting when and where large flares will occur.
Project demonstrates Panasonic and Coronal's continued alliance in eco construction market NEWARK, N.J., March 20, 2014 /PRNewswire-iReach/ -- Panasonic Eco Solutions North America
Peabody Engineering, a family-owned manufacture-ring company in Corona, recently talked with California CEO Magazine about the launch of its cellular antennae enclosures and cloud-based tank monitoring
In the first episode of "Do Good Mob" Carter and his team head to Corona California to meet "Jeffrey's Hope," a non-profit that is working on raising $1 million dollars to build Universal Playgrounds
A giant sunspot – a magnetically strong and complex region on the sun's surface – has just appeared over the sun's horizon. This is the third trip for this region across the face of the sun, which takes approximately 27 days to make a complete rotation.
The sun emitted a significant solar flare, peaking at 7:49 p.m. EST on Feb. 24, 2014. NASA's Solar Dynamics Observatory, which keeps a constant watch on the sun, captured images of the event.
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.
University College of London researchers have explained for the first time the details of how the Sun’s coronal mass ejections behave when falling back onto the star’s surface.
Corona -- The corona is the luminous "atmosphere" of the Sun extending millions of kilometers into space, most easily seen during a total solar eclipse. An interesting feature of the corona is the fact that it is much hotter than the visible "surface" of the Sun; the photosphere is approximately 6000°C compared to the corona at over one million °C. The corona is much less dense than the photosphere, however, and so produces less light. The exact mechanism by which the corona is...
Solar Prominence -- Solar prominences are large arch-shaped structures observable in the solar corona. These often have a twist and occasionally become unstable, ejecting plasma and magnetic flux out from the sun. The physics of solar prominence instability is believed to be governed by magnetic forces and magnetic helicity issues. It is thought that instability occurs when a magnetic flux tube becomes excessively twisted. ----- Click here to learn more on this topic from eLibrary:
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...
