Starship Asterisk*

Looking at the full image - in the area around pixel location 1997,1652 - there's something curious, at least to my eye. Zoomed in, it's about 5 pixels (35 ish meters) across, and very sharply demarked. The obvious answer is that it's a small upthrust of some kind, or a large loose boulder - but to...

Is this the first full-circle star trails image published widely? I seem to remember a few months ago, APOD (or maybe it was over at the Bad Astronomer blog) that nobody had done one. At the time, I expected someone to pop up fairly immediately with one, as it seemed a *relatively* simple task (yeah...

I have to agree in general on the over-all readability - it's good. However, the linkage within the explanation is often somewhat problematic for me, as it's often pure guesswork what I'm going to find at the other end, even though I know what site specifically it's going to. I would like the explan...

But the reality is, figuring out the distance to most objects inside our galaxy (unless they are very close) is difficult, and most published distances have high uncertainties. So who really knows? Of course, that's one reason why scientists don't generally bother to assign local supernovas to any ...

In the full-sized image, there's an object located at about 8 o'clock to the main image showing an extent. I'm curious as to what it is (obviously, it's probably a planetary nebula), and I'm used to stars in Hubble images showing some coloration - so I'm wondering why the stars in this one don't, an...
