It's also nice that moon has a planet.

What do you mean?

After the next landslide, they will say "Who knew this could happen".
I knew.

: falls over laughing! : O, beyond, I'm SO glad I was eating my toast rather than swilling my cuppa joe, or I should have surely needed to issue an RKA (ruined keyboard alert)!! As it is, I have some crumbs to clean up, and there's peanut butter on the wall. Well worth the clean-up effort, that was...

Spiral arms are essentially fixed standing waves and stars orbit into the concave side of these arms and come out the convex side of these arms. So the arms aren't rotating, the galaxy as a whole doesn't rotate? Stars pass through them as they rotate around the galactic center; the composition of t...

Wish this was a real picture.
We should send a lander there, with a Titan orbiter.
I know Huygens went there, but it could only send limited data for no more than 2 or 3 hours, because the Cassini probe had to be nearby to relay the signal to Earth.
It would cost just a few days of the Irak war.

I'm waiting for your explanations of all and every things...

Looking at the image, that spot doesn't look colder than other spots.

I fear that "Guest" is a Utilitarian, who like Gradgrind would begrudge his children a visit to the circus, because it is a "bastion of Fancy and Conceit" (Hard Times) John "Guest" did suggest we could have been "exploring Callisto, Enceladus, building telescopes&...

We could have welcomed immigrants. You mean we haven't been?! :shock: Clearly mexicans are not welcome, that's why they have no choice but to come as illegals, and I myself have spent 32 years trying to emigrate to the US from Canada but was never allowed to because I have no family there. Yet we a...

The lunar jeep seems positionned ready to go
Where does it come from ???
Did they drive it reverse gear all the way ???

It's not a jeep, it's a two-wheeled hand-pulled cart, a bit like those used for grocery shopping here.

When I take a picture here on earth with my camera, I never ever see any star. I would need a special setup to see any, like special camera or long exposure.

One of the stitched images could see behind the thruster.

I remember seeing a very similar image from Skylam in the 1970s.
Looking for it, I found it was taken on 1973 dec 19.
You can see it there:
