Starship Asterisk*

What? No "color commentary" from our "Color Commentator"?

So, I'm wondering why in some scenes the Moon "exits" the Sun on the lower left, and on some the lower right.
I also was disappointed that the compilation had the "large cloudy sunmoonrise" broken up through the video, instead of being a contiguous clip.

And forgets to point out the Bear Nebula!

Some local municipalities in the United States have banned the use of these products. An ordinance in Houston, which went into effect in 2010, prohibits the use of all attention-getting devices, claiming the use of such devices "contributes to urban visual clutter and blight and adversely affe...

I think it looks like a dog with :D very big ears! Don't you mean Thor's Donkey? smallDonkey.png (I tried to include a .png outlining the donkey head, but I guess I need to use an image service such as Pinterest (which I don't have/use) Edit: Thanks johnnydeep for the info on adding the photo!

Plausible, or sucked into a Black Hole?

<<Ursaab ("original Saab", a.k.a. 92001 & X9248) was the first of four prototype cars made by aeroplane manufacturer Saab AB, which led to production of the first Saab car, the Saab 92 in 1949. Ursaab was driven over 530,000 kilometers, typically in utter secrecy, and usually on narro...

It’s beautiful and technically well done but these type of composites I find are leaving me cold. They really look unnatural with the super saturation and the foreground that just looks “fakey” for lack of a better word. It’s the same problem with HDR, most people just overdo it in spades. The fore...

How many sheets could a sheet slitter slit if a sheet slitter could slit sheets :?: The slitter question... First of all we need to clear something up; and that little 'something' is the use of the word 'if' - the reason being that sheet slitters CAN slit sheets, so there's no 'if' about it. Sheet ...

Inre: the artist's impression.
The 3 super massive stars are shown on the same plane, is that how it must happen, or is a 3-D "tumbling" more likely?

So, how long before I get promoted from "Science Officer" (inre: the avatar and personal info tag) to "Court Jester, Junior Grade"?
(neufer is Court Jester, First Class) B^)

What the picture and the text don't tell us is that the Crew Dragon was a couple of minutes behind the ISS. At the time, they weren't traveling alongside each other as one might gather from the picture alone . Thanks for explaining that [Joe Stieber], I was wondering, "If it is only 6 hours in...

Authors have hypothesized that some viruses arrived from meteors, and exist in low orbit over earth. It would be interesting to see a link to a report on this. Another theory on the origin of virii is that they devolved from more complex organisms. That is seen in a salmon virus that has vestiges o...

Ah! You've found Aldebaran!

Am I in that picture, or ... was I on the other side of the Earth when the picture was taken? We need to know the exact time the picture was taken! You are in the picture, but you were moving at the time, so your image is quite blurred. Next time, stand still when your picture is being taken! :ssmi...

Did the ISS eclipse Aldabaran?
In other words;
Where is that big red star that is usually inline between Orion's belt and the 7 sisters?

Instead of Ingenuity, I think they should have named it AMEE (Autonomous Mapping Evaluation and Evasion) after the robotic dog in the movie "Red Planet" which had a helicopter type drone which it would launch and recall for increased surveillance.

Thanks MarkBour and neufer for the illustrations!

The Hubble photo in infrared makes a nice addition. Sorry, don't know how to create the link. https://www.spacetelescope.org/images/heic1007f/ Okay, here's what I "discovered"; When you are writing a comment, notice the "buttons" (e.g. B (bold) U (underline)) above the Text box....

Perhaps, but it would sure be sweet to be able to fly along and within it in a helicopter! Not accounting for conventional engines not working in the thin atmosphere, I wonder just how large (long, wide) the rotary wings would need to be for a "helicopter" ( one or two human occupants) to...

Yes, certain catastrophes are good for observational astronomy in that they make the night skies darker.

This reminds me of the accomplishments of brilliant observational astronomer Walter Baade during the blackouts of World War II:

He sounds like "one Baade Dude!"

Minor nit - the Himalayas are the *highest* mountain range - at 4000m tall Everest isn't actually that big. Hawaii is the tallest - soaring 10000m from sea floor to peak. (Didn't I learn that on APOD?) I thought a mountain in Ecuador was the tallest (from the perspective of furthest from the center...

Vega is "white" only because the standard filters are normalized to give it a B-V of zero. Again, astronomical color is a quantitative value that isn't directly related to physiological color. Astronomically, the color of a star is basically just a measure of its temperature. Ladies and G...

Everything that looks green on the Earth has to have a "spiky" spectrum, with a sharp spike in the green part of the spectrum. Like grass, or like planetary nebulas.

Ann

Such as the "rare" green sunset.
