freagle, w Astronomy has a major data problem. Simulating realistic images of the sky can help train algorithms

Astronomy is constantly discovering never-befor observed phenomenon. The idea that you can simulate realistic images of anything requires you to have sufficient knowledge of reality, and astronomy keeps showing us that we don’t have that.

The only way I can see this being helpful is to train algorithms for what is already known and can be safely filtered out, making it easier to detect new observations

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.

[…] only a few hundred of them have been detected in the local universe

Why haven’t they checked other universes?

Nice. It’s a huge cock and balls

Zaktor, w “The models were right”: astronomers find ‘missing’ matter

That’s some hard long science right there.

TLDR: it’s the hot gas filaments between galaxies that they confirmed

Always appreciate updated and current videos on the process, even if I can’t mimic on Linux.

Something that has always frustrated me about the editing process is that every program has its own unique features

Some you get wavlets

Some you get stacking and aligning

Some you get level adjustments and curves

All while most of the programs are deprecated and/or abandonware

I think currently I have Registax, Auto Stakkar, Siril, PiPP, and Gimp installed for processing just because some programs perform features better than others.

treadful, w Starlink Satellites Are 'Leaking' Radio Emissions

The polarisation of the broadband emission shows the flux density of two orthogonal polarisations is anti-correlated with temporally shifting spectral structure observed.

abcdqfr, w 1.5TB of James Webb Space Telescope data dumped on the internet — new searchable database is the largest window into our universe to date

Tangent, how would this telescope do turned around and pointed at our deepest oceans? There’s infinitely more alien life to actually find and study, and it’s still unstudied for good reasons I suppose I’m fishing for.

Wait… what?

We’ve got tons of oceanographic satellites. James Webb is extremely good at picking up light. The ocean is extremely dark.

Okay quacks, time to go data-mining for anomalies!
