A hypnotic new NASA video shows a solar filament erupt, causing explosions and then forming a series of giant magnetic arches of solar material, all of which ultimately collapse into the sun.
“The arches of solar material appear to glow as they emit light in extreme ultraviolet wavelengths, highlighting the charged particles spinning along the sun’s magnetic field lines,” the space agency said in a news release.
Solar filaments are arcs of plasma in the sun’s atmosphere, which appear as dark lines because they’re not as hot as the rest of the sun, according to the University Corporation for Atmospheric Research.

The sun will look like a ring of fire above some remote parts of the world next Tuesday (April 29) during a solar eclipse, but most people around the world won’t get a chance to see it.
Whereas lunar eclipses occur only when there’s a full moon, and solar eclipses only happen during a new moon. Half the world saw a lunar eclipse during the full moon on April 15. When a lunar eclipse occurs, it usually means there is also a solar eclipse at the preceding or following new moon.

Comet ISON is teasing the solar system as it dances with the sun and it’s giving astronomers mixed signals.Will it meet a fiery death – or survive – when it whips around the sun on Thursday?
The icy comet will be only about 1 million miles away from the sun’s super-hot surface during its close encounter on Thanksgiving. On Monday, it looked like it was about to die even before it got there. On Tuesday, it appeared healthy again.
“We have never seen a comet like this,” Naval Research Laboratory astrophysicist Karl Battams said during a NASA news conference Tuesday. “It has been behaving strangely.”
Because it is so close to the sun, ISON (EYE’-sahn) will likely not be visible from Earth on Thursday – except via a fleet of NASA telescopes and spacecraft aimed at the comet as it gets closest to the sun at 1:37 p.m. EST, he said. And it will be a few hours before scientists know whether the comet survives.

NASA can prove it now. Our solar system has a tail, just like comets.
Scientists revealed images Wednesday showing the tail emanating from the bullet-shaped region of space under the grip of the sun, including the solar system and beyond. The region is known as the heliosphere, thus the name heliotail.
The findings are based on data from by NASA’s Interstellar Boundary Explorer, or IBEX. The Earth-orbiting spacecraft was launched in 2008.
Scientists always presumed the heliosphere had a tail, but this provides the first real data on the shape.

Tomorrow is the big day. Time to dust off your eclipse glasses, binoculars and posterboard, or pinhole camera and witness the transit of Venus, a once in a lifetime event! (Actually, it’s a twice in a lifetime event, but if you missed it eight years ago, this is your last chance!)
