Starship Asterisk*

When I clicked on the "Discuss" link in today's APOD, my browser went to yesterday's discussion.
Did that happen with anyone else?

Can someone please explain the giant Luna through a telescopic lend part? Did the people there see an ordinary sized moon? And does the lens type affect the apparent speed also? It has nothing to do with the lens, and only the relative distance between the observer, intermediate objects, and the Mo...

I wonder about the large gap of undisturbed sky between the black hole and the seemingly serenely orbiting puffs of gas and dust that encircle it. Ann I think the (common) dust and gas are "smart enough" to keep clear of the Black Hole, but the "celebrity" (star) isn't. B^) http...

Is the "bump" off to the right a satellite / dwarf galaxy? Star formation in M77.png You mean this bump? That's a region of star formation. You can see a few blue star clusters inside, surrounded by red gas structures. A whitish patch "below" the blue star clusters shows where b...

Sorry to get theological on you great folks...

But, I think, someday in Eternal Life, I may get to view, if not travel, this vast beautiful universe!

Okay, neufer, your turn to put me down!

I see ghosts!

Has Millet accurately rendered a particular group of stars? Or is it just a star-like spatter of paint? Rob The three stars in a row in the upper right look suspiciously like the belt of Orion but I can’t recognize anything else... Eric I agree, then the blurry stars below them and at top right wou...

That's a "colourful" way of commenting!

Or send astronauts (muskonauts?) who are red-green color blind?

it is a smaller nebula inside the dolphin, and it resulted in shaping the dolphin's "snout".

So, when a 1st stage (intended for re-use) splashes into an ocean, would the engines have cooled off enough to keep them from being damaged by contraction? I'm guessing that is why SpaceX lands them on a barge. @neufer, The positronium reference was interesting (I had never heard of it previously) w...

And I thought I was having a bad hair day!

It looks like a beaver doing the back stroke.

Not sure I've seen that attempted before.

I wish I had "a hair day"!

Taking in account the present precession of the Earth, is there a bright star that marks (scribes) the Celestial Equator? Orion straddles the celestial equator, and Mintaka (the northernmost of the belt stars) sits just 19 arcmin south of the equator (compared with Polaris, which is over 30 arcmin ...

"This Sun-circling robotic spaceship will monitor the Sun's changing light, solar wind, and magnetic field not only from the usual perspective of Earth but also from"

How is this spaceship going to monitor the Sun, from Earth, AND outer space?

When i see romantic pics like this it amazes me there isn't a booming moondustry yet getting ppl up there to see it for themselves and experience the open and vast void of space.

Okay,
What is the "BD" and other annotations on the APOD photo?
I'm confused.

Most decent modern DSLR (or similar) cameras can take very nice Milky Way shots. Use as high an ISO setting as the camera supports without getting too noisy (which has gotten pretty high on many cameras- 3200 or more), shoot as long of exposures as you can without getting star trailing- with a mode...

I wonder if my DSLR is capable of taking such a "deep" photo of The Milky Way.
(I'm not referring to the entire composite APOD)

Any tips for me?
