Starship Asterisk*

tom_gauld_science_hell.jpg In case there's any question, DL Martin is Tony in this example. Also, DL Martin, I am pretty tired of dealing with your reported posts. If you don't stop trying to badly explain spacetime to us on your own from here on out, you might find that you will be stopped by othe...

Yeah, I'm sure it will work out and everyone will get it and all our problems will be solved, just like the solar tiles and the transit tunnels (were trains going in those or cars? I forgot).

I'm starting to think that you might have some kind of motivated reasoning about it, Chris. <snip> the massive human benefit of universal data connectivity. <snip> It's not going to be universal. The system throughput is going to be too low for many people to use at one time, so cross out the world...

Hi Chris, many thanks for your annotation. But there now is a request. You are sure, that starlink is nearly invisible? Maybe, there will be ca. 7000 in LEO at a hight of appr. 340 km. But there will also be 1500 at an orbit of 550 km and 2500 at 1200 km. And ... why is the ISS on an LEO-orbit of 3...

There's always the option to simply not talk about things you know very little or nothing about, then. Especially if the only purpose is to spread further negativity in an already negative world. Just saying. You have no idea what I know little about, nor do you know what I know much about. To assu...

Ah, ok, so the person responsible for the birthday website would have to add an http header that would allow apod.nasa.gov to display the content in the iframe, so I'm afraid that won't work unless you know who to contact. If you did know how to contact, it's actually a pretty easy thing to do. Anot...

Have you tried placing this where the image normally goes on an APOD test page? I wanted to try something simple like that, but I can't actually test it because my test document is not located on a nasa.gov server. Seems only nasa.gov websites can load the iframe. Edit width and height as you see fi...

Took quite a while to load. At least 5 minutes. Pretty cool!

Am I missing things? To each their own, but some art is properly enjoyed with history lessons. Nocturnes are a rare kind of painting, and van Gogh... is van Gogh. Thank you for being so understanding. I do do the Art History thing if the art is, in my opinion, worth my efforts and time. Vincent's i...

Is there a particular reason a few of the stars have black dots at their centers? This is a symptom of an overload on the image sensor because the star was so bright due to a long exposure. Ironically the overexposed area flips to black. Well, close. It's a processing error that is common when deal...

In my opinion, artists renditions should be banned from this site and every other scientific publication that seeks to be legitimate. These are pure fantasy. They have no business on a scientific web site. Journals do it too. It's common in Science and Nature. Shameful. They're informed by reality,...

It looks great!

I never have understood the perspective of these types of shots. If we are within one of the spiral arms of the galaxy, how can this perspective of an arm be achieved from earth? Either we'd be looking out from within the same arm in the image and it doesn't make sense to me that it would look so s...

Owlice retired from her job and she now travels to far away places, goes to astronomy conferences to talk about ASCL, takes good care of her kitties, and even has her own office at the University of Maryland. She is still good friends with the APOD editors, and she still manages the APOD mirror site...

What Chris said. It's just the point spread function for that filter with Spitzer. The PSF is pretty dramatically different between IRAC and MIPS. Every star gets a ring, but not every star is bright enough for it to be obvious.

Hi great day to you all, I am new to this community. I noticed an unusual object in "Cosmic Clouds in the Unicorn (2020 Feb 08)" at right centre of the frame, it looks like a "Dora cake". was just curious to know what it is. Looks something very strange. Does it look like this h...

When did a dromedary become not a camel?

When I read that, I thought it meant light echoes. I went ahead and posted a reply to try and get RJN to clarify for us here.

Not related to the opening, but someone had a tangent question regarding relativistic illumination: viewtopic.php?f=8&t=40217

Well spotted. Yes, it does look as if something rather tiny is forming in there, probably a red dwarf star or maybe just a brown dwarf. If you can see the jets coming out of a molecular cloud, it's a sign that the object is still accreting and not yet in its final form. I always see them called YSO...

Nice, Elias!

The resident "know it all" in my workplace has said that when Betelgeuse explodes, its cloud will eventually engulf our solar system reducing visible stars to about one third. Has anyone else heard/read of that? Not even close. Even assuming that the material isn't dissipated unevenly by ...
