From everything I've read and thinking about what MRO is for, where it's cameras are pointed, etc... that IS Mars in the background. And they didn't remove it as much as change the camera's optics. It's like taking a photo with backlight on/backlight off. It is an effort to improve the contrast and ...

Strange indeed. It took me a long time looking to see the crater as a crater and not a mesa. Then, I could see the rays as canyons and not ridges. So we have a series of canyons leading to a double impact site... one significantly older than the newest. And, to me, it sure looks like the older is th...

I saw something once that made the structures look like the walls of a pile of soap bubbles. Neurons is another good picture.

Google oops?
Downloaded Google Earth 4.2... which I'm calling Google Space.
Found an object I'm wondering about... sure looks like an image of a telescope.
Dec -13deg 30'08.89"
RA 6H39M34.39S
Anyone? And why's it there?
Of all the awesome pictures of the Pleiades, why did they not pick one to put in?

I love discussions on this subject. Your question is pretty simple to answer but not an easy concept. At this very second the Universe LOOKS exactly like it appears to us in these pictures and with our own eyes. Yet it looks completely different to whatever intelligent life may be living in that 60M...

1500 ly away is distance and time, you're right. So if we see something that is 1000 yrs old (time only) then really it's now 2500 years old. We're observing something as it was 1500 years ago... even though it appears to us as if it's happening now. This brings up some other subjects that are inter...

I have taken a 20 minute exposure before. I used a simple 35mm camera with a 200mm lense. Used a plunger shutter control and locked it open. The trick was that we mounted it onto a telescope that I was looking through with my own eye... so the camera was pointed in the same general direction as my t...

The night sky turns. This exposure was time lapse and the camera took that turning into account. Thus from the perspective of the camera, the sky stayed perfectly still, but the ground turned... causing ground lights to move but sky lights to be perfectly still. Takes some skill and patience, but th...

Mars: Southern Polar Ice Cap (APOD 13 Dec 2001)
http://mars.jpl.nasa.gov/gallery/polaricecaps/browse/br_PIA02393.jpg So here's my question: Is there any data on the size of the polar ice cap today compared to, say, the Viking missions or other observable years? My ultimate idea is to compare that of a planet that man has had practically NO impac...

The answer to seeing it in AM and PM is the turning of the earth. Compare the morning and evening and imagine the earth spinning. Sorry, I know that's not a great explanation. Probably too simplistic. Another way to think about it is this... the comet is neither leading nor trailing the sun... it's ...

Is this not the projected orbit of the stars?

Also, curious... should we expect to see some (any?) lensing?
