Re: APOD: Sharpest Ultima Thule (2019 Feb 28)
I can imagine it to be a normal process that an object of that size forming in a proto-planetary disc gathers more material along its plane of orbit or equator. Rotating and gathering layer after layer on the same area. Once the mass is too great the structure collabses under its own gravitation and...

One article explains: "At the center of the giant butterfly-like feature is IRc2, a star 30 times more massive than the sun which is in the process of forming. A strong wind with a speed of more than 100 kilometers per second is blowing out from IRc2, evacuating the butterfly-like cavity and a...

If we could look directly along the axis of the homunculus and see the star(s) at its center, would it not appear similar to the Eskimo nebula or the Cat's Eye nebula? In other words, are they not all similar structures, but seen at varying angles? This might interest you. [youtube=https://www.yout...

As for the red color, Ultima Thule is not the only Kuiper Belt object that is reddish. Pluto, for example, is too. But how can it be that Pluto is reddish while Charon, moon of Pluto, is mostly grey ? I'd like to have that explained to me. Ann Not an explanation more a guess. My guess would be Char...

Re: APOD: Cerealia Facula (2018 Jul 19)
There seem fault lines nearby. I wonder if this salty mass might have been pushed out like outcrops on earth. Like exposed salt domes. Such mass doesn't need to be wet with water to flow. Maybe shrinking of the asteroids crust and shape due to an cooling core caused it.

The jets are formed by gas and particles of the accretion disc that just escape the black hole. Like gaining speed by a malstroem b...
