Starship Asterisk*

Curious: Near the center of Olympus Mons is what appears to be bombardment craters. Although it looks like a crater caldera, it appears more likely to be a series of strikes, perhaps from a 'string of pearls' hit by a shattered asteroid. Am I correct?

Over 30 minutes of image the comet will not appear to move much at all, at least to an unaided eye. I found the Noctilucent clouds more fascinating!

An amazing image. Is this object planar or spherical? How can you tell?

But I'm curious - 1/5000 second is beyond human reflexes (at least it is beyond mine) - is this photo taken with some kind of ultra-hi...

Since these are formed in what is apparently sedimentary rock layers, could they be sink holes? Put a layer of sand on a cardboard, then punch a hole it it.

It is only a question posed as to how the site might be promoted. For the purposes of getting exposure to more people, sure, call...

The caption explains that changing the time or location would change the appearance of the annalemma. What change will there be over the course of several years? Will the next year be identical? How long until the annalemma repeats exactly?
