NASA Releases First 3D Images of the Sun 80

Posted by CmdrTaco from the break-out-the-glasses dept.
mvar writes "On Feb. 6th, NASA's twin STEREO probes moved into position on opposite sides of the sun, and they are now beaming back uninterrupted images of the entire star—front and back. 'For the first time ever, we can watch solar activity in its full 3-dimensional glory,' says Angelos Vourlidas, a member of the STEREO science team at the Naval Research Lab in Washington, DC. NASA released a 'first light' 3D movie on, naturally, Super Bowl Sunday."

    STEREO, as the name suggests, has been broadcasting 3D images of the sun since it launched many, many years ago. the satellites had slightly (and increasingly) different viewpoints, which could then be combined to give a binocular view of the sun. The long-term mission was to put the satellites at opposite sides of the sun for continuous coverage of the surface, a position in which they cannot generate 3D images of it because their perspectives are completely exclusive. That is what has been achieved.

    • (I should say anything above the limb of the sun to one satellite is above the limb to the other satellite as well, and can be viewed stereoscopically. They're only mutually exclusive for the sun itself.)

      Stereoscopy (!="3D") isn't particularly attractive for such, quite "smooth" for the distances involved, almost-sphere anyway...

      But what they now achieved is very much 3D - we can have a decent, current 3D model of whole Sun (well, polar regions most likely suffer major loss of detail, as well as lowest latitudes which aren't at any given point in "head on" view)

      I think you are missing a key adjective in your reading of the quote.

      Emphasis mine. Previous 3-D images did not contain the full surface of the Sun as the two probes would have to be on opposite sides of the Sun to achieve such. They are now and thus there is no missing portion of the surface of the Sun. The page name also says it all:

      ...which means that we now have a 3D model of the sun at any point in time for as long as these probes have been opposite each other. You can now in theory load this model into Blender or Celestia and view the sun from any angle, not just from two fixed viewpoints. Hell, you could build one out of papier mache if you wanted.

      This is true 3D, as opposed to stereoscopic (think 3D films) which was all we had when the probes were close together, and so far as I know the first time this has been done.

      I guess that is best a problem that we leave to future generations to solve. I ain't certainly going to be around to worry about it.
