Starship Asterisk*

Couldn't understand one basic aspect. Why the eclipse is seen starting from west coast in US to east coast in US.. Apparent motion of moon from east to waste should be faster than Sun's apparent motion from east to west.. So I was imagining it'd start from east coast and move towards west coast. An...

This January 20, I noticed ice crystals sparkling in the light of the golf cart I was using to bring hay to our sheep. It was very cold, maybe around 5F. I live in middle Tennessee, and this kind of cold is unusual. I then noticed that, when I looked toward the lightbar on the golf cart, the sparkl...

I've seen the same thing with oncoming headlights here in Colorado (where it does get that cold sometimes in winter). I think I saw that once or twice in New York state when I lived there. But seeing it close up with a bright light is amazing. The photos were taken from about 30 yards away. There w...

I think the ripples are shock waves, and are not caused by "pockets of relatively hot or rarefied air deflecting moonlight less strongly than pockets of relatively cool or compressed air.."

Hmmm,,, quick questions - 1) Brightest portion in the middle.. is that where the friction with Earth's atmosphere is the strongest (e.g. left origin up above atmosphere, so not that bright, right ending portion after the max burn falling down from sky) ? Or some other reason ? 2) Why blue-green lig...

Wow, great photo!

I know this comment is a little late, but... Could the unusual mountains opposite the orbiter near the lunar terminator be remnants of the original body that slammed into the earth, or even part of Earth's crust? Or did the original moon have to have been totally liquid rock?

Why are there extra lobes of the jet in the upper-right?

I guess my favorite Moon image is this one: https://upload.wikimedia.org/wikipedia/commons/thumb/a/a8/NASA-Apollo8-Dec24-Earthrise.jpg/1024px-NASA-Apollo8-Dec24-Earthrise.jpg It's a picture that really puts the Earth and the Moon into perspective. You have to gasp when you see it. At least it makes...

I would think that the meteor was at least the size of a small pebble. Most meteors don't create visible trails that drift - but the larger ones do.

https://apod.nasa.gov/apod/image/2307/PhobosMars_MarsExpress_960.jpg I find it hard not to think of the asteroid that killed the dinosaurs on Earth when I look at today's APOD! And of course, Phobos is going to crash on Mars. Assuming there are any people left on the Earth to watch the spectacle wh...

Great photo!
It was cloudy here when they were closest together.

Here's how Jupiter and Venus looked here tonight in TN, USA. The foreground was lit by an almost full moon behind me.

Here's my, rather poor, photo of comet ZTF.
Taken on Jan 28th.

Here's what Stable Diffusion 2.1 came up with after I added the keywords, "exoplanet, red dwarf, lava mountain rocks sunset". The red dwarf looks to be in front of one of the mountains. The caption does say that it's a "small red star." exoplanet red dwarf lava mountain rocks sun...

Sadly, I'm still incapable of crossing my eyes enough to get the images to overlap. I can only get them to partially overlap. Unless there is something seriously wrong with you, you can most definitely cross your eyes enough to overlap the images. The amount of crossing necessary is like looking at...

Cool! Though it would be easier to see it in 3D if the two images of Mars were closer together in the pic. Also, the clouds and ice cap look different because the images were taken about two days apart. Why not a half hour or so apart? Here's a 3D photo I took a few years ago. It's also viewed by cr...

Yes, my bad. Fixed on the main NASA APOD. Apologies!

No problem, thanks.

The paragraph starts with a string of words that is not a full.

Does anyone know if they are planning on making a time lapse of the protostar and the surrounding nebula? It would be very cool to see the dust orbiting and/or being blasted out of the system.

Yay for an actual photo!
It may be a little blurry, but I still like it.

About two days ago, I actually watched a video that featured this photo.

Here it is.

I thought the same at first. I thought CA meant California.
