Starship Asterisk*

My visual cortex struggles to process the last few seconds

Oh, not where I looked for it at all

So where's the Big Dipper?

Very illuminating, Ann

Thank you for this detailed description, Ann. Seems to me that the APOD's explanation

red and yellow regions shine primarily because of emission

is not quite accurate?

typo, Phygrian - Phrygian

measured between 2 and 4.5 feet (0.6 and 1.4 meters) in diameter.

quite a flash for how small it was.

I'm confused. The smaller Ou4 does look like both a squid and a bat, the bigger Sh2-129 certainly doesn't resemble a bat whichever way I look at it.

I have a question: in galaxy pictures with this kind of resolution, can we see their globular clusters and if so, how do I tell one from a dimmer foreground star from our galaxy? You can see them, and they look a lot softer than a MW star and lack diffraction spikes. They'll usually be lumpy, too. ...

Interesting, I thought the mechanism was well understood.

ditto.

What a remarkable little world.

Wikipedia disagrees on the size of UGC 2885 being 800kly. It also claims that the largest known spiral galaxy is 'only' 650kly.

Not a chance that it's related to the merger?

What's the bright glowing blob near the right edge?

The links to the discussion, the previous and next day are all the same as for the Oct 04 page

Older APOD entries of the Horsehead Nebula have the same text except for one word, now it says: After many thousands of years, the internal motions of the cloud will surely alter its appearance and before it said: After many thousands of years, the internal motions of the cloud will alter its appear...

The link to the next day is broken: it's /apod/ap19011.html, should be /apod/ap190611.html

1/10 animation, ecliptic perpendicular to the galactic plane. Just kidding, it's quite beautiful.

What's the bright source below and to the right of the center?

I too have this question. How come one particular star was magnified?

The walls are surprisingly opaque when looking from within. The night skies on a planet in that valley would be an interesting sight.

I'm surprised all those holes aren't absolutely full of rocks after 5 years of work.

If a static image is worth a thousand words this must be worth a million: Hubble's Variable Nebula Looks like the shadow casting dust is possibly orbiting the star in a counter-clockwise direction. Taking top-up in the animation, I'd call that clockwise. There's also the conventional reference of n...
