  1. We've all see cool NASA images but THIS takes the cake. A five year compilation of images of the sun in three minutes.
    1,826 Days in Space
    2,600 Terabytes of Data
    200 Million Images
    Simply Amazing!
  2. Thank you Louis for the link, it is truly amazing and breathtaking.
  3. Thanks Louis. A stunning group of images - I learned more about the sun in that 4 minutes than in the rest of my life.
  4. Exceptional. Thank you Louis.
  5. That is amazing, thank you Louis. Also a little scary in a way. Our very existence is dependent upon that mysterious roiling mass of heat and gas.
  6. Wow, that's the ultimate in time-lapse photography!
  7. Excellent. I know this is time lapsed photography. But I've seen shorter version of "explosions" and always wondered if those were time lapse or real time because the amount of space covered seems to be faster than light would travel. Anyone have details on this?
  8. Alan. The duration of smaller solar flares can vary from seconds to minutes to hours, and the duration of larger coronal mass ejections can be from hours to days. When looking at some of time lapse videos of the sun, you can get an idea of the timing by considering that the rotation period of the sun at the equator is approximately 25 days (some of the video clips appear to have the rotation movement compensated for). I have looked at the sun through a single wavelength (hydrogen alpha) solar telescope, and all the features looked stationary to my eye. However, if a short duration solar flare did occur when viewing, the sudden increase in brightness might be noticeable in real time. More information at: .
  9. Impressive. Enjoyed that very much, thanks.
  10. Thank you Louis, but let's wait just ~500Myears and we will see this show without any NASA device. Indeed the sun will then begin to grow bigger and ultimately will swallow the earth's orbit. No more need to boost color saturation in Photoshop..
  11. Thanks Louis, very impressive. I could be without the soundtrack and it would have benefitted from some explanations of scientific results.
  12. Glenn thanks for that link. The top video one on page 3 showed a clock so you can see the hours it takes for the CME to eject. It would be nice if others would add a clock to their videos. All of those I've seen in the past did not show a clock leading to confusion as to the time element, an important criteria of the phenomena.

    In addition to the video description on the youtube page, the SDO website has a ton of material for your consumption.
  14. Thanks Rob. Can you provide a link ?
