Starship Asterisk*

I expected the link in the text to “eight successive” exposures to show those eight individual images instead of a picture of eight cats. Any explanation? And of course, then there is the Moon and the Pleiades, minus any cats. https://upload.wikimedia.org/wikipedia/commons/thumb/e/e9/Nebra_disc_1.j...

I expected the link in the text to “eight successive” exposures to show those eight individual images instead of a picture of eight cats. Any explanation? One cat. Two cats. Three cats. Two more cats, and maybe four. And Bastet, the cat goddess of Egypt, with the Sun and the Moon. https://i.pinimg....

Amazing image, Jac!! :D :clap: 😃 🥳 I'm a sucker for ultraviolet images, because they show us the blue objects in the Universe! 💜 💙 💜 I absolutely love the pair of images that show the difference between the visible and ultraviolet appearance of NGC 346: https://science.nasa.gov/wp-content/uploads/2...

Wow! Yes, I know, this is a repeat image, but Sundays are repeat days, and this image is certainly spectacular enough to be featured as an APOD at least twice! https://apod.nasa.gov/apod/image/2409/SaturnMoon_Sojuel_960.jpg What creates the illusion that the Moon has rings is the fact that the long ...

If you watch scifi shows you’ll notice that to create conflict space ships are subjected to a whole lot of dangerous storms in space analogous to hurricanes and rogue waves to terrestrial ships. “Ion storms”, a “nebula” that wreaks havoc, etc. Have astronomers found anything like that? Assuming a d...

There is a lot to see in this APOD! https://apod.nasa.gov/apod/image/2408/NGC7769_70_71_Mandel_1024.jpg APOD 31 August 2024.png The stellar streams from the interacting pair of NGC 7771/NGC 7770 appear to mix with the IFN of the Milky Way, so that it's hard to say where the NGC 7771 star streams end...

Yes, that's a nice APOD! :D https://apod.nasa.gov/apod/image/2408/MoonEclipsesSaturn_Sanz_960.jpg But I have a few questions: 1) Why is Saturn so very "strongly striped"? Only Jupiter is that striped, right? 2) Why is Saturn so colorful? It colors range from yellow-white to yellowish ochr...

At that distance, this 1.5 degree wide field-of-view would span about 150 light-years. In t...

As Enceladus is spewing out water containing organics, shouldn't those surface features be a sort of mucky brown colour? As for the color of Enceladus, this is the best I can do: https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgT0WwAVPd-EzWeUBo_A6GzcyZ2ZXd_ActBHqNP-jAoYpHD6qFFLxvshQznsYM...

The activity of Enceladus is astounding, for such a tiny Moon! https://apod.nasa.gov/apod/image/2408/EnceladusStripes_Cassini_960.jpg Enceladus is about the size of Great Britain, and it could fit comfortably inside the Gulf of Mexico: https://i.ytimg.com/vi/8Mbwra56Ty4/maxresdefault.jpg https://med...

Wow, that's beautiful! :D https://apod.nasa.gov/apod/image/2408/FijiMoonsetWangJin1060.jpg I remember seeing something similar, minus the palm trees and the ocean, when a brilliant full Moon was setting seemingly inside a bluish cloud bank below a lovely pink dawn sky. But the Moon shone right throu...

Not sure what you mean. We see supernovas all the time. Do you mean nearby? The last one we saw in our own galaxy was in 1604. We're due. _ sn2023ixf_20230523.jpg Yes, I meant seeing one nearby with our own eyes. Must see this once in my lifetime! (I remember your two images "evolution of a su...

Remnants, always remnants… When do we get to see an actual supernova? Not sure what you mean. We see supernovas all the time. Do you mean nearby? The last one we saw in our own galaxy was in 1604. We're due. _ https://asterisk.apod.com/download/file.php?id=50217&t=1 Great picture, Chris! :D Ann

Of course, we see our own galaxy exactly edge on, so that we see many layers of dust features superimposed on one another. In Andromeda, we see the dust features separately. Is that why the dust lane of the Milky Way appears to be thicker than the dust features of Andromeda? And is that why we see ...

I liked this entry too, about the Wow! radio signal from 1977. https://scx1.b-cdn.net/csz/news/800a/2024/the-wow-signal-deciphe.jpg The Wow! signal lasted for 72 seconds and was extremely bright: https://scx1.b-cdn.net/csz/news/800a/2024/the-wow-signal-deciphe-1.jpg There has been widespread specula...

Very interesting today's APOD. Quick 2 questions - 1) What's the size of the sky captured ? Is it full (whatever is "visible" to space telescope) ? e.g 13 billion light years across 360deg ? 2) Since the data is of 12 years, I'd imagine some prominent gamma ray bursts might have got recor...
