The Case For Mars [?]

I came across this opinion piece the other day. To Replace The Shuttle: A Mission To Mars The author is pushing for human exploration of Mars. Fine. A few of the arguments used by the author are very typical of folks defending human space exploration. 'Human spirit,' global focus on a goal to keep s...

Re: APOD: Mercury's Surface in Exaggerated Color (2011 Jun 1

Happily, that's not going to happen. Many of the images shown here are not even collected in visual light bands to begin with. How should they be displayed- as a black box linked to some other visual version? Do you suppose this goes back to the tendency people have to think of the visible part of ...

Re: The Spirit of Butts Farm

It says it used a "computerized navigation system." I wonder how that worked? With size and weight restrictions, there is a limit to how many instruments could be on board for the computer control system to use. I assume it used GPS? That way it could get not just navigation information bu...

Re: Beauty of Space

I've always really liked astrophotography images that include elements of the horizon - trees, edges of mountains, ect, even though they often show us what we can't see with our eyes. Of course, what you can see with your eyes - in dark, remote areas away from light pollution - is an incredible expe...

We had a thunder storm the other evening. I saw a few flashes; it was just cloud-to-cloud.

In general the weather around here has greatly improved! We had some really nice days last week and more are on the way - partly cloudy and in the low 70's.

Re: Globular Clusters

We know globular clusters are very old, so the process of evaporation must take a while. Have astronomers speculated on possible variables that might affect the length of time it takes for a cluster to evaporate? Overall mass? Relative velocities of stars within the cluster?

Well, considering that our entire history as a sentient species is just a snapshot in time relative to the age of the solar system, I imagine it is entirely possible that Venus at one point or another has had a captured moon or two.
