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

      Around 8,848 meters high, it’s the tallest mountain in the world.

  • Tori

    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.

    I suppose it just depends on the person!

  • Anonymous

    wow that was strange. it didn’t take me a half an hour to see.. more like 10 seconds, but at first i couldnt figure out why i couldnt see it correctly.

  • Anonymous

    i dont get it!!!

  • Anonymous

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

  • Anonymous

    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.

  • otowi

  • Anonymous

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

  • Anonymous

    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.

  • Anonymous

    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

  • Anonymous

    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.

  • robert

    First comment!! I don’t really understand what i have to do

  • Anonymous

    ya right

  • Whitney

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


  • Anonymous

    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

  • Anonymous

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

  • Politikally Paranoid

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

  • mountaineer

    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.

  • sandyandy

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

  • Anonymous

    Turn your head slightly to the left

  • Anonymous

    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

  • random gurl265

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

  • NaME

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

    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 looked at it and to me it looks like a ski hill with trees on it.

  • PK

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