Philip Terry emailed me another NASA picture of the day. This picture of Mt. Everest was taken from the space station, posted on the NASA website. Phillip said: “What’s the deal? I stared at this picture for a half an hour, seeing it inverted. I had to leave and go back to the computer to see it correctly. Then it’s really hard to see it inverted again.” This also happened to me! I first saw it concave, but after seeing it convex, I couldn’t switch again. It’s the same deal we had previously with embedded hand print. Be sure to check other similar illusions, like: Bjorn Borg, dragon illusion and Machu Picchu.

    1)I don’t understand, are we supposed to find the bigfoot figure in this picture?

    2)Do you think they took the picture at night and used flash?

    3)this mountain doesn’t look so big, I don’t understand why its so hard to climb, then maybe thats also an illusion.

    Take care, adam

  13. Tori says:

    Its still sticking out for me! All well, guess I just stink at this. I found that if I cross my eyes a little, the pic becomes a little sharper looking.

  17. Yes says:

    I can’t see it at all, it stays convex for me.

  18. Anonymous says:

    I don’t get it. I can only see it as the way it was meant to be, convex.

  21. Anonymous says:

    I get it, after staring at it for 10 min. My eyes started to glitch. It freaked me out. Its not the best illusion though.

  22. otowi says:

    that’s a really good one, you just have to change the way you think of it.

  29. Anonymous says:

    If you don’t see the mountains, try tilting your head to the left while looking at the picture – it may just pop out at you.

  30. Anonymous says:

    1) it’s so hard to climb because it’s at a huge altitude and it’s hard to do anything
    2) you see bigfoot?
    3)they could never use a flash big enough to see that clearly without blinding everybody there

    I don’t get it. What is it suppose to be? I don’t even know what I’m suppose to be looking for, so how can I find it? I’m not sure as heck going to spend 10-30min just looking at an image.

  34. Whitney says:

    Hm..I dont understand. Can someone please point out the actual mountain and valley? Thanks..

    lol, wow that took me a while to figure that out !
    At first I thought the top left of the picture was the closest to the camera, like a rock face, but now I see the landscape view, where the closest bit to the camera is actually in the bottom right of the photo

  36. Anonymous says:

    haha. i see an ear in the left lower corner. lmao..

  37. Politikally Paranoid says:

    Someone tell me where bigfoot is!!!! I wanna see him. I’ve been looking and looking, but I don’t see anything…..:^(

  38. mountaineer says:

    There’s no secret.
    Its just: shades not showing to a used direction.
    If you rotate the picture about 45° clockwise, or turn your head to the left, so that the river/street leads straight toward you, then you see immedeatly the normal mountains.

  39. sandyandy says:

    theres a face s-e where it dips with a”road”

  40. Anonymous says:

    Turn your head slightly to the left

  41. Anonymous says:

    i saw what you mean. when you save the picture, look at it first rotate to the right until the picture is upside down, rotate right again until you got the picture to itd original position and you’ll see that the rocks changes from concave to conves. but if you rotate it to the left, you find that it goes back to being concave from convex

    i really dont get it ! i dont c n e thign except cracks . lol

  43. random gurl265 says:

    all i see is a rock. and a fist in the lower left corner. luckilly ur not weird hottshott. :P

  44. NaME says:

    I only see a face in the top right corner on onwe of the mountains

  45. Lindsay says:

    Our brains are use to the lighting of objects coming from above. In this image the lighting is coming from below (bottom right). If you rotate the image 180 degrees it becomes obvious what is going on.

    An easy way to switch from convex to concave is to sweep your eyes from top left to bottom right (concave) and then from bottom right to top left (concave).

    I see a tulip

  57. Touhou says:

  58. PK says:

    Look at it as if the black outlines were shadows and the picture was taken from slightly above and in front. Not directly above..
