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.

will be visible across the Americas

Proceeds to list 3 regions in North America where it will be visible.

Akt0, w Question about lunar calendars

But we don’t have a ‘Year 0’, it goes 1BCE to 1 CE.

Lunations are only ~29.5 days long, between specific moon phases. They still count one year as 12 lunations, ~354 days. Right now is Rajab on the Islamic Calendar, but that’s still the month, not the moon. According to the Farmers Almanac, January is the Wolf Moon, taking from both Native American and European Colonial traditions.

Yes, there are multiple counts. Rajab is the 7th month of the Islamic (Hijri) Calendar, AH 1447, while Tevet is the 4th month of the Hebrew Calendar, AM 5786.

Hopefully this helps, and I understood you correctly. If not, Wikipedia has charts of the current date according to multiple calendars when looking at specific calendars, like the Islamic Calendar, or you can look more at Lunar Calendars, and the differences between Solar, Lunisolar, and Lunar Calendars.

“If we posit this position,” he wrote, “then they, that crowd of Aristotelian know-it-alls (scioli aristoteli), will cry out and stone us

God damned stoners.

This works something like that: www.timeanddate.com/astronomy/night/

TheFunkyMonk,

Nice! I used the Astronomy API for planet positions and the 7Timer API for astronomy weather conditions, I wonder if they’re using those as well.

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…
