Yup, that's why I chose it a pareidolia (face on Mars, pyramids) within a pareidolia (lion head).

Next the second Starlink satellite train. Hard to believe they could lay track in space though. Contains music.



Edit for spelling thanks even though speel check doesn't like that one either.

↑ They will really ruin astrophotography! :x

And it's pareidolia (from eidolon, image).

My concern also, with todays image processing though a bother it can (hopefully) be dealt with.

:oldman: Why I remember a time before the damn Ruskies put up that first piece of space junk.

I was under the mistaken impression that our Sun was about as small as a star could get and still maintain nuclear fusion. :? :?

And if there are stars smaller than Earth, why didn't Jupiter and Saturn ignite long ago?

If we could only easily transmute matter.

Talk about messing up astrophotography.

How is it that something is massive enough to sustain fusion can be smaller than the earth? Unless it's a neutron star, but oh, wait: If it's a neutron star, it no long maintains fusion now does it? Indeed, it could hardly have collapsed to become a neutron star if it did still support fusion.

Smart aleck! :)

So while all the stars in the pleasant little diagram can truthfully be called stars, there is a difference and an important one if I've reasoned correctly.

Ping an astronomer STAT!

I'm probably wrong but they may be white dwarfs,like that little guy in Game of Thrones.

"A white dwarf, also called a degenerate dwarf, is a stellar core remnant composed mostly of electron-degenerate matter. A white dwarf is very dense: its mass is comparable to that of the Sun, while its volume is comparable to that of Earth. A white dwarf's faint luminosity comes from the emission of stored thermal energy; no fusion takes place in a white dwarf."

Cool links in there. Never heard of a black star before. Its basically like a black hole, but not strong enough to form a singularity or an event horizon, but its gravity is just strong enough to prevent its own light from escaping.

I can relate.

I'm just fat enough to be considered obese in medical terms, but not fat enough to be considered obese by any of the morbidly obese, nor fat enough to keep light from escaping so you can see me coming. :wink:
Such potential!
