kalkulat, 23 dni temu do astronomy w Boiling oceans may lurk beneath the ice of solar system's smallest moons

are known to have oceans of liquid water between the ice shell and the rocky core

The ‘oceans’ are not ‘known’, They’re a hypothesis based on gases escaping at the surface. Ever put a drop of water on a red-hot skillet?

That ‘ocean’ could be 1mm thick. Sloppy science writing. ‘Exceptional claims…’

Astronomical bookkeeping 🥴

Hydrogen alienation is a crime.

showmeyourkizinti, 11 miesięcy temu do astronomy w Astronomers find massive supernova remnant closer than previously thought

Ok so from what I can understand it blew off approximately a million years ago, and now it’s about 8.8k ly away. But where was it in relation to earth when it exploded?

Is dark matter just dwarf galaxies?

If it's not seen as much, that probably means the green material is heavier than iron. It's less common, but large enough stars can fuse even heavier elements. That's where all those elements on Earth came from in the first place.

Maybe for you but I’m built different.

Dubiousx99, rok temu do astronomy w Japan's precision moon lander has hit its target, but it appears to be upside-down

Looks like someone missed a negative sign in the equation to account for the reverse gravity direction. /s

Fermion, rok temu

Or they installed an angular velocity sensor upside down. also /s

SanctimoniousApe, 2 miesiące temu do astronomy w Sharper than ever: New algorithm brings the stars into greater focus

What kind of alien god is looking on from deep space in the upper right? I see two eyes, a mouth, and the dark shading varies just enough to look vaguely like a head.

I’m starting to think maybe I’ve had a few too many arguments intense discussions with alien conspiracy theorists…

emuspawn, 5 miesięcy temu do astronomy w Astronomy has a major data problem. Simulating realistic images of the sky can help train algorithms

What kind of algorithms are those trains running?!

Make sure you check out the simulator webpage for some sweet old school design and a lot of neat pictures! I love a good simulation.

TonyTonyChopper, rok temu do astronomy w Earth bids farewell to its temporary 'mini moon' that is possibly a chunk of our actual moon

I’m amazed that we can detect a 10 m wide object at 4 million km away. Let alone track its trajectory.
