NASA Captures 3D Images Of Sun

NASA released the first three-dimensional images of the sun Monday, saying the photos taken from twin spacecraft may lead to better predictions of solar eruptions that can affect communications and power lines on Earth.

"The first reaction was 'Great, the instruments work.' But beyond that the first reaction was 'Wow!"' scientist Simon Plunkett said as he explained the images to a room full of journalists and scientists wearing 3D glasses.

The enthusiasm was mirrored at planetariums across America, as audiences put on their glasses for an out-of-this-world show, reports CBS News correspondent Jerry Bowen.

The pictures taken by the orbiting twin satellites may help scientists do what they do on Earth: forecast the weather.

"We'd like to be able to do the same things with solar storms but we aren't there yet," said Mike Kaiser, a NASA project scientist.

The images from the STEREO spacecraft (for Solar Terrestrial Relations Observatory) are also available on the Internet and at museums nationwide.

The twin spacecraft, launched in October, are orbiting the sun, one slightly ahead of the Earth and one behind. The separation, just like the distance between our two eyes, provides the depth perception that allows the 3D images to be obtained.

That depth perception is also particularly helpful for studying a type of solar eruption called a coronal mass ejection. Along with overloading power lines and disrupting satellite communications, the eruptions can endanger astronauts on spacewalks. Scientists would like to improve predictions of the arrival time from the current day or so to a few hours, said Russell Howard, principal investigator for the Naval Research Laboratory project.

STEREO program scientist Madhulika Guhathakurta said scientists have until now been "modeling in the dark" when it came to predicting solar storms. The twin spacecraft give researchers the vantage point to "provide the observations needed to validate the models."

The sun has been relatively quiet since the launch, so STEREO scientists have not predicted the arrival of any storms yet, Plunkett said.

The eruptions, also called solar flares, typically blow a billion tons of the sun's atmosphere into space at a speed of 1 million mph. Besides power and communications problems, the phenomenon is responsible for the Northern Lights, or aurora borealis, the luminous display of lights seen in the upper latitudes of the Northern Hemisphere.

With all of these comments dedicated to Billy instead of the article's subject, one might think that the sun shines out of Billy's you-know-what!

There is a logical reason to study the Sun. The activity on the Sun can knock out electrical grid on Earth and orbiting satellites as well.

So NASA has wasted money on nothing. The Sun is hardly nothing. I think little billy would just prefer the Sun exploded or something so scientists couldn't study it. Or maybe the money should be sent over to win the Iraqi war or report on the good events there. Or maybe, oh forget it. Anyone who doesn't dind the study of the Sun interesting is not worth wasting words over. Afterall if there wasn't any Sun none of us would be here to complain about studying it would we? Americans waste more money on makeup than on the Space program. Come to think of it, perhaps makeup isn't a waste either.

This comment is for Billy: Maybe the next time you start whining & complaining, you should have
spellcheck turned on.

What is an engineer? A mechanic who specializes in a certain area of construction: Aerospace, electricity, hydraulics. And who performs the research in those? Scientists. Yes, weather prediction is a process of elimination - through use of logic, based on evidence of past occurances (forecasters call these 'models'). Without scientists to expedite matters, I think the engineers would be out of a job, billy.

They get all excited about those lousy grainy out of focus photos with the wierd color filters (blue red gree etc)??

"NASA has really wasted allot (sic) of money for nothing..."

What kind of creative spelling is that?

why so bitter little billy? couldn't pass your 2nd grade math class or something?

Nasa brought us Tang and that nice viscous foam mattress many of rich folk can afford. Your hate the science and the scientist mood is doing nothing but causing you aging stress.

I suppose a cure for smallpox or polio just isn't good enough for little billy. maybe they should be trying to build a better car for NASCAR instead of NASA to make little billy happy.

what sour, sour attitude. you don't think the gov has enough money for science, we'll just print up some more.
