This is a pop-science problem and not a real science problem. Any astronomy imaging system worth its salt has image stacking algos that remove transients easily enough.
Hi, it’s me. An actual scientist. Did grad school in planetary science. The same techniques we use to spot asteroids are the techniques used to spot satellites. But removing them is even simpler. It’s not algorithmically hard at all.
In fact, it’s so simple that I’ll write it out: take several images (at least three) in quick succession and take the median value across those images.
Oh hey, that was easy. Makes a good despeckle filter too for cosmic ray strikes or whatever else.
I mean, I’m pretty sure you’d be able to see it from everywhere in Australia, so I bet many of them would be like “WTF?” But they’ll be dead soon. Fuckin’ kangaroos.
The light blue part is shallow and when it’s underwater, they call it “continental shelf”.
Tasmania and mainland Australia are connected by the same, shared continental shelf.
If that photo was taken right before impact, none of the continents will remain continents because it’s all about to melt and we might have another moon when everything settles down and we evolve back from scratch over the next several billion years.
When they came for Pluto, I said nothing because I wasn’t a planet
When they came for Australia, I said nothing because I wasn’t a continent
When they came for Bielefeld, I said nothing because I wasn’t a city
When they came for me, there was no one left to say anything
Even more amazing that it was found in the era it was. People were pouring over the skies looking for the next big planet, and instead they found this little guy.
There are still some orbital dynamics suggestions that something large and dark is lurking out there – an ice giant. But it’s still largely conjecture. It’d be interesting to see how they define it should they find something very large (say Neptune mass), but it hasn’t cleared its orbit. Is it a planet or not? :D
Actually 🤓 it was James Cook who found Australia and he didn’t go there by ski but by ship and he didn’t find one little guy but exterminated a whole indigenous population
They only found it because it’s more like a binary dwarf planet system than a planet/moon system, so the telescopes were able to pick up light reflected from both Pluto and Charron, while Pluto alone might have not been bright enough.
