ExotiqueMatter, w Milky Way may not be destroyed in galactic smash-up after all
@ExotiqueMatter@lemmygrad.ml avatar

What do you mean after all? Wasn’t it the consensus since forever that there was basically 0 chance of anything actually colliding because galaxies are mostly empty space? I’m pretty sure I read about that when I was a child.

How do Sedna and that new one have a stable orbit? Are they that fast, to be able to compensate the movement of Pluto?

Delta_V, w "Big surprise": astronomers find planet in perpendicular orbit around pair of stars

I wonder if its a product of colliding galaxies?

keepthepace, w [Eric Berger] Tuesday Telescope: A rare glimpse of one of the smallest known moons

What I like about this image is that this is probably the biggest object that I can compare to something I know, that I can “comprehend”. With 6 km wide, it is about the same size as Grenoble, a city I have seen from above while hiking. I can understand how far the picture looks from it, how small a human would be on it

I actually think about Deimos a lot

I biked out to a park yesterday with my big binoculars but I’m still waiting for my tripod to show up so I just checked out the moon some. Thanks for posting.

conditional_soup,

The Pleiades and Hyades should still be fairly high in the sky, and make great targets for binoculars. I’m also VERY partial to the little beehive cluster in Canis Major (go to the first barely visible star down from sirius, along the dog’s spine, and move directly right from there). If they’re strong enough, the Orion Nebula also makes a great target. The regular beehive cluster is alright; it can be tricky in the city, but you should juuuust be able to see what kinda looks like a faint, blurry star just left of the angle of you make a right angle between Pollux and Procyon. There’s also a few binary stars that make good targets right now. You should be able to split the first bright star out from the cup in the handle of the big dipper into three stars.

Fourth,

Appreciate it, looking forward to future posts from you.
