NASA Solar Satellite's First Sun Images 103

coondoggie writes "NASA today showed off the amazing first pictures of the Sun taken from its 6,800lb Solar Dynamics Observatory flying at an orbit 22,300 miles above Earth. The first images show a variety of activity NASA says provide never-before-seen detail of material streaming outward and away from sunspots. Others show extreme close-ups of activity on the sun's surface. The spacecraft also has made the first high-resolution measurements of solar flares in a broad range of extreme ultraviolet wavelengths."

    SDO will provide critical data that will improve the ability to predict these space weather events.

    I do not know what everyone else thinks but I think that sounds pretty exciting. I can see it having a huge impact on airline and space travel.

    I downloaded the 40mb(h264 mov) file which was all of 31 seconds. What would be super awesome though would be a torrent of a longer period of an hour at least. Pretty please NASA? If the Norweigans can do it with a train ride surely we can do it for a great solar instrument like this.

    No, real nerds would argue about the mass of the chick, right in front of her...

    Wait a minute... 1.5TB/d = 500,000 iTunes/d??
    This would mean that iTunes has only 3MB? The size of a song...
    OMG, those complete retard mean MP3s!!
    I bet they refer to MP3 players as “iPods”...
    This is even dumber than not knowing the difference between $0.02 and 0.02 cent!

    "space weather" is a term used to refer to solar output fluctuation so the layman can understand it. It has more to do with radio and electronic systems on earth and in space than it does to earth-bound weather.

      My pleasure!

      Something else to think about - you spoke of energy levels - just one of those granules is about the size of the Earth*, and the average temperature at the surface of the sun is around 6000 Kelvin. If the earth was magically transported there, everything on the surface would evaporate instantly, and the oceans would boil completely away in a matter of minutes. The rest of the planet might last a few days, at the most.

        We humans, with our fusion weapons, think we have "harnessed the fury of the stars" while in reality we've barely touched upon the energy levels that are common everywhere - and our sun is just a "middle class" star in terms of energy levels. There are phenomenon out there that make our sun look like a spark in a nuclear explosion...

      The universe is both beautiful, and terrible beyond imagination.

      Welcome to astronomy :) One of the greatest pleasures I find is in expanding minds...

      * roughly; the sun is about a million miles in diameter, and granule size varies. It's a close enough approximation, however.


There are running jobs. Why don't you go chase them?
