Sun's Canyon Of Fire: New NASA Video Shows Spectacular Eruption

NASA said that the 200,000-mile-long filament ripped through the sun's atmosphere called the corona, leaving behind something like a fiery gorge. The video, which was created by combining two days of satellite data, shows a tongue of flame blasting away from the sun, firing superheated gas into space.

The images were captured on Sept. 29 and Sept. 30 by NASA's Solar Dynamics Observatory, or SDO, which constantly observes the sun at a variety of wavelengths. Different wavelengths help capture different aspect of events in the corona.

According to scientists, the sun is not made of fire, but of something called plasma, which are particles so hot that their electrons have boiled off and created a charged gas that is interwoven with magnetic fields.

The red images shown in the movie help highlight plasma at temperatures of 90,000 F and are good for observing filaments as they form and erupt, NASA said in a statement. The yellow images, showing temperatures at 1,000,000 F, are useful for observing material coursing along the sun's magnetic field lines, seen in the movie as an arcade of loops across the area of the eruption.

The video also contains brown images at the beginning, which highlight material at temperatures of 1,800,000 F.

By comparing this with the other colors, one sees that the two swirling ribbons moving farther away from each other are, in fact, the footprints of the giant magnetic field loops, which are growing and expanding as the filament pulls them upward, NASA said.

On Wednesday, the sun emitted another mid-level solar flare, which peaked at 8:30 p.m. EDT. According to scientists, the flare was among the weakest that could cause some space weather effects near Earth.

Harmful radiation from a solar flare cannot pass through the Earth's atmosphere to physically affect humans on the ground, but if they are intense enough, they can create disturbances in the atmospheric layer that is home to satellites hosting Global Positioning System, or GPS, and other communications systems.

NASA telescopes to peer deeper into universe than ever before

16 hours ago

NASA / ESA / J. Lotz & M. Mountain,STScI

These are NASA Hubble Space Telescope natural-color images of four target galaxy clusters that are part of an ambitious new observing program called The Frontier Fields.

Three NASA space telescopes are teaming up to give astronomers their best-ever looks at some of the most distant objects in the universe.

The space agency's Hubble, Spitzer and Chandra space telescopes will collectively observe six huge galaxy clusters over the next three years as part of a project called The Frontier Fields. Working together, the trio should be able to spot galaxies that existed just a few hundred million years after the Big Bang created our universe 13.8 billion years ago, NASA officials said.

"The Frontier Fields program is exactly what NASA's Great Observatories were designed to do: working together to unravel the mysteries of the universe," NASA science chief John Grunsfeld said in a statement. "Each observatory collects images using different wavelengths of light, with the result that we get a much deeper understanding of the underlying physics of these celestial objects." [Cosmic View!

The Hubble Space Telescope observes in visible, near-infrared and near-ultraviolet wavelengths. Spitzer is optimized to view in the infrared, while Chandra sees best in X-ray light.

The Frontier Fields project will take advantage of a phenomenon called gravitational lensing, in which the gravitational field of a massive foreground object bends and brightens the light from a more distant object, acting like a lens.

In this case, the six huge galaxy clusters starting with Abell 2744, which is also known as Pandora's Cluster will be the lenses, and the magnified objects will be extremely dim and far-flung galaxies, some of which have likely never been observed before, researchers said.

"The idea is to use nature's natural telescopes in combination with the great observatories to look much deeper than before and find the most distant and faint galaxies we can possibly see," Jennifer Lotz, a principal investigator with the Space Telescope Science Institute in Baltimore, said in a statement.

Media Invited to NASA Google+ Hangout Briefing on Antarctic Ice Campaign

NASA will host a live Google+ Hangout news conference on Tuesday, Oct. 29 at 3 p.m. EDT about Operation IceBridge's upcoming airborne field campaign in Antarctica.

This is the first year IceBridge will operate directly from Antarctica, flying from McMurdo Station starting in mid-November instead of from southern Chile. This change will allow IceBridge researchers to survey parts of Antarctica previously unavailable to them since the mission began in 2009.

IceBridge is a multi-year NASA science mission to study ice conditions at both poles. The mission's survey flights gather data on changes in ice elevation and thickness and measure the shape of bedrock and water cavities beneath ice using a suite of scientific instruments. The mission provides critical measurements that bridge the gap between observations supplied by NASA's Ice, Cloud and Land Elevation Satellite, or ICESat, and the upcoming ICESat-2.

Panelists for this briefing are:

-- Michael Studinger, IceBridge project scientist, NASA Goddard Space Flight Center, Greenbelt, Md.

-- Christy Hansen, IceBridge project manager, NASA Goddard Space Flight Center, Greenbelt, Md.

-- Chad Naughton, project manager, National Science Foundation's U.S. Antarctic Program, Centennial, Colo.

The Hangout will be broadcast on NASA Goddard's Google+ and YouTube pages and carried live on NASA Television and the agency's website. Journalists can submit questions via comments on these pages or on Twitter using the hashtag #IceBridge.

Small is big at new nanotechnology lab in Wheeling

U.S. Secretary of Education Arne Duncan helped inaugurate a special science lab in the Chicago area Thursdayand attended a separate event promoting more rigorous learning standards.

Wheeling High School officials say their nanotechnology lab is the first of its kind in a U.S. public high school.

Teacher Nancy Heintz says the labs high-powered microscopes can drill down to the nano level. How small is that? Think of the Lincoln Memorial on the back side of a penny, she says.

If you imagined the eyelash on the Lincoln in the Lincoln Memorial on the back of the penny that gets you pretty close to the nano level.

Heintz says teachers were able to see single atoms of copper when they came to learn how to use the scanning electron microscopes and atomic force microscopes over the summer.

On Thursday, students showed off images of things theyd seen close up: butterfly wings, strands of hair, a DVD.

Senior Bryan Zaremba was impressed by paper. It looks almost like a spider web, you can see all the fibers, he said.

This is zoomed in at 3,300 times, so its pretty small, explained his lab partner, Eric Kaplan. On the computer screen was an image that looked more like a gray, post-apocalyptic forest than a scrap from someones notebook.

Next to Zaremba was a scanning electron microscope which looks like a large desktop computer tower. Theres a crystal in here that shoots electrons down at a sample, and when the electrons hit the sample, they bounce back to detectors, and they build an image, Zaremba says.
