Starship Asterisk*

That's a nice list, Art. What is it a list of? Elements, yes -- presumably elements created inside a star. But a particular star? The progenitor star of this particular SNR?

Ring, Bar? Where exactly? You better gave an indication (e.g. in red dots when waving the mouse over the photograph) of - the bar and of - the ring. I easily see two rings: a ringlike structure in the very center if the galaxy, and the stucture with blue enclosing the yellow part of the galaxy. I h...

News item this morning (first I'd heard of this) suggests that the billionaire and team will be looking at the possibility of reducing the satellites' albedo, now that people have begun to express reservations. I can't imagine why this idea would come so late to the table. You'd think anyone putting...

My kingdom for a spike removing filter.

42 -- obviously.

Really cool pic, but please, please, please, would people stop saying something is 150 times, or some such, smaller than something else? That is nonsensical. It may be 1/150th the size or Luna may be 150 times larger than Phobos. Thank you. I agree. I find it distractingly odd to read something lik...

It has been a sore point with me for years now. Many years ago Arizona Highways began to airbrush any water that appeared in photos taken for the magazine. At first, it was unique, and it was fun to see. However, to airbrush away the beauty of water has become boring, if not irritating. Please give...

Are all the "big" stars here part of the Milky Way? There's one bright one coincidentally appearing very near the center of M33 ... that's not in M33 right? http://www.visibone.com/images/M33%20center.png Closeup of the center Any bright spot with radiating spikes will be a star in our Mi...

One of the things I love about the really large pictures APOD posts is that you can often find interesting things in the background. For example - at about pixel 75,750, there's a sharp point of light surrounded by lots of fuzziness. It doesn't exactly look like the normal elliptical/spherical gala...

I downloaded the hi-def image and had a look at it in my image editor. The image is quite sharp in only the center bottom area, and gets progressively less sharp as you move up and to the left or right. I can't recall seeing that in similar selfies taken by other rovers. Anyone know why it's so in t...

If I could spin a tale, I would choose it to be set in George Gamow’s world. A 3D web set into motion by the collision of three black holes. So far, so good… Many were caught up by his read . Mine more likely to result in … D’oh! :blah: That book was really important to me when I was 18 and startin...

It's a bit like the old story of the man who was looking for his keys one night just below a street lamp. When asked if he had lost his keys under the street lamp, the man replied that he had actually lost them somewhere else, but that it was too dark to look for them where he had actually lost the...

The fact that acap seems to respond to my own posts with total bewilderment would support that idea.

I often respond to your posts with total bewilderment, Art. Yet I'm sure I'm a real person.

That was precisely my point, Rob(ot?).

Oops! I was be-bewildered I see.

Bojo looks a little like a wolverine in that view, Fred. But he appears to be a lot friendlier.

My strong suspicion is that acap is a real person. The fact that acap seems to respond to my own posts with total bewilderment would support that idea.

Why did I just hear Ma & Pa Kettle while I was reading that, Bruce? I suppose a bot could find and review those old movies, but they'd likely make it insane. Come to think of it, they may have made some humans insane too.

... Just last week a report said the rings of Saturn will rain down on Saturn and disappear in 100,000 years. ... The Moon is moving away from Earth and in 100,000 years there will no more be total eclipses of the sun. ... I think you (or that reporter) missed a few zeros. Saturn's rings may be gon...

For anyone around at the time. what was the hippie revolution of the 1960's like?

The Moon (ours) will be, once we get back there, a lot like a mining colony for a long time to come. If you don't work there, you won't be there. Mars will be, once we get there, more like a science colony (think Antarctica). If you don't work there, you won't be there. Colonizing in the romantic se...

You should have a look at the Interstellar Travel Wikipedia page, as well as the Interstellar Probe page there.

Although Whitefish Bay is at the east end of Lake Superior, it juts down to the south; this photo was evidently taken on the west bank of the bay, and was shot looking east, toward an island out in the middle of it. A little south of the island, I think. Those points of light along the thin streak ...
