Sounds like the galaxy used its gas to gaslight NASA into thinking it is a galaxy

itsnotits,

used its* gas

Damn autocorrect, fixed now. Thanks

outstanding_bond, w NASA Selects a Wild Plan to "Swarm" Proxima Centauri With Thousands of Tiny Probes

A very cool idea, however the headline is misleading - NASA has not even remotely committed to running this mission. They’ve selected the swarm project as one of 13 projects in their innovation program and given it up to $175k to study feasibility. That’s roughly a postdoc for two years. This is far, far from committing the hundreds of millions or billions needed for the execution of this mission.

okay, report:

  • good lord, Antares and Vega are offensively bright once you adjust to the dark.

  • M4!! HOLY GUACAMOLE WOW! M4 by itself made being out tonight worth it!

  • M80: cool, felt cool to find it, but it looks like any of the other tighter globs and I didn't want to mess with switching to one of my narrow AFOV higher power eyepieces on my manual dob. May revisit once I invest in a higher power eyepiece with a decent AFOV.

  • Epsilon Lyrae: hmm, am I maybe just not using enough mag? looks like a regular double star to me.

  • Took the telescope for a slew through Sagittarius, for a laugh, was not disappointed. Breathtaking amount of stars there.

  • Was all aboard the strugglebus making sense of Hercules's constellation. Didn't help that he was at the zenith, which made using the dob weird when looking for M13 and made looking at the constellation annoying after staring straight up like a turkey for minutes.

  • Took some time to re-acquaint myself with Draco, Cygnus, and Aquila.

  • Didn't pick out any more DSOs, in part because I got annoyed with blowing out my night vision, even with the red light, on my charts.

  • I've been fairly serious about the hobby for about 9 months now, and it seems like I saw way more satellites out tonight than I did when I stopped back in May. Bruh, the little bastards were everywhere.

That is pretty f'n sweet

emuspawn, w Astronomy has a major data problem. Simulating realistic images of the sky can help train algorithms
@emuspawn@geostationary.orbiting.observer avatar

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.

Why haven’t they checked other universes?

Winged_Hussar, w Learning The Basics Of Astrophotography Editing
@Winged_Hussar@lemmy.world avatar

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.

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.

@Dasus@lemmy.world avatar

Wait… what?

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

RedSnt, w Milky Way may not be destroyed in galactic smash-up after all

But don’t worry either way:

Phew!

no galactic smash-up is expected for billions of years, long after our ageing Sun will have burnt away all life on Earth.
