HurlingDurling, w NASA Finally Removes Last Two Fasteners To Access Historic Bennu Asteroid Sample
@HurlingDurling@lemmy.world avatar

This canister opening has to be conducted under the most pristine conditions to not contaminate the sample, so this was quite the issue.

Since they couldn’t just take a circular saw and cut through it

And here I was going to suggest some WD-40 or a blow torch could help.

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

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.

SW42, w Open journal question regarding Cosmology paper

Or - and that is just hypothetical- they want to show it to their colleagues smirking and saying “get a load of this guy”.

Farmdude,

I can tell have this way about you. It’s so on the money. Your money

SanctimoniousApe, 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…

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.

buggy-pull-buggy, w Citizen Astronomers Help Confirm New Temperate Jupiter

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.

bleistift2, w The Cosmic Owl: Astronomers discover a peculiar galaxy merger

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

Why haven’t they checked other universes?
