Comments on: A penetrating, double-ringed crater on Mars

I tried rotating the picture every which way, and even covering the brightly lit area, and could not for the life of me get it to look like a crater. I finally Photoshopped the hell out of it, darkening the highlights, lightening the shadows, and adjusting the midtones. That made it looks mostly ike a crater, but the left side of the blue ring still looks very very tall, and the bright spot on the right still seems to go up instead of down.

I understand the layered terrain (well, how would it be called on Mars…) but how can you rule out a double impact? I mean a smaller crater created in the middle of larger one?

must be seen from more oblique angle ( for me ) to be appreciated.

That´s cool.
Yesterday I was watching “Pavlov” a dutch science series about us and our sometimes (weird) brains. Why some people are better in some things than others and what they experience when doing their thing. Yesterday was about people who can taste sounds (a musician), or see colors when they hear/see a word (a DJ) etc. It´s about how our brains work. Facinating stuff. They shove ´m MRI´s and do ECG´s etc and you see were their brains light up when presented with a word/sound/image, not only in the word/etc part of their brain but also in their taste sensation part or whatever they sense.
So I´m not surprised you can see both at will and others not.

It can go from crater to hill or hill to crater as I watch it, no blinking or looking away. It’s not necessarily when I “tell” my brain to change it. It just happens on its own. But usually it only remains a crater for a second or two.

The size of a stadium? I say put a dome over that sucker and throw the first interplanetary monster-truck-Mars-mudbog rally! The ticket sales alone would fund several years of deep space research. This Sunday-Sunday-SUNNDAAYYY!

Like when you were a kid, in bed… shadows and forms in the curtain. So your mind went *eekz* and you saw a face. Then after you turned the light on, it was gone, light out again and it was not there anymore. I used to try if I could get the face back, sometimes you could and sometimes it was gone forever.
Eyes and brains are a weird mix sometimes. And fun to play with.

Funny. When I look at it, the crater indeed looks like a hill. But when I tell my brain “it’s crater” it kinda pops in and then I see it as a crater, as it is. At least as long as I’m looking at it. As soon as I look somewhere else and look back at it – it’s the hill again! I guess that’s the default setting of my visual cortex.

I eventually saw this as a crater after shrinking the picture to about an inch wide. When that small I couldn’t get it to look like a hill at all. Now I can’t see the full size one as a hill. Isn’t perception a weird thing?

I love it how my eyes still kepp seeing a mount and not a crater.
And I like how “we” (as a species) discover all this.
“Simply” by launching something. The wonders of the universe are right around some corner (depending were ypu do your slingshot).
Just as I like the show the Red Arrows gave here yesterday. Physics right in front of you!
