kryptonidas, w Public stargazing classes

I live half a world away so I can’t attend but I think it’s a cool concept. I have no idea how long it takes to re-align the scope between takes.

There is definitely some magic in that, I don’t know if you have both scopes, then you can set an automatic up for people that just want to take a quick peek, and use the manual to explain your story.

conditional_soup,

It doesn’t take too long to adjust unless somebody really headbutts the scope, which happens. Typically it’s just slewing targets back into frame because of the Earth’s rotation, which at 110x and a good RACI, is pretty easy. I think it takes maybe 15-20s every third guest to make sure they’ve got a good view (takes a bit longer sometimes if they’ve pushed the focuser in). I’m definitely thinking that a GOTO/PUSH TO modification kit might be in my future, but I’m trying not to spend more money at the moment.

Oh! That’s why my life is in the toilet!

Rude!

Duck!

showmeyourkizinti, 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?

I was just out enjoying Jup & Mars … couple hours too late for Ven … maybe it’ll be clear tomaro nite!

It’s not where I am sadly, cloudy all night looks like but on the 24th my next clear day but if it’s clear where you are Venus should be visible with the naked eye from about 16:00

threelonmusketeers, w Rapid colonization of a space-returned Ryugu sample by terrestrial microorganisms

“We found aliens! Wait no, it’s actually just us again…”

SynopsisTantilize,

We should just bio-seed a planet just to see what happens. Like really …what’s the worst thing that could happen? (Genuinely asking)

Cause the way I see it, we could very well create a new planet or asteroid or moon with micro life on it. It would be nifty.

XeroxCool,

The worst that could happen in our lifetimes, I would say, is be a total waste of money and resources since no other reachable bodies have atmospheres suitable for Earth-based life. Beyond our lifetimes, and possibly beyond humanity’s existence, that life may be able to survive somewhere but any kind of evolution likely takes millions of years and long-term survivability may not let it see that day

Mbourgon,

Odds are we already have: Mars, Venus both have had landers, and given that the protections from bringing bacteria are similar or worse than this lander, the only reason bacteria would not have survived is due to heating of the landers in atmosphere. IANARocketScientist.

Fortunately, we found this out now, before we drop a red hot lander through the ocean surface of one of the moons of (I can’t remember) which they suspect could have life

mumblerfish, w DESI confirms Einstein's model of space-time, limits alternative explanations

preference of the data for dynamical dark energy

That is a quite weak statement, I presume it implies that this result has not excluded a cosmological constant by a long shot, bacause that would have been huge.

Conspiracy theorists: “scientists know it’s all wrong but they’re preventing the truth from coming out to protect their precious ‘theories’”

Actual scientists: “crap, our theories were dead on yet again, damn it, will someone please finally blow even a tiny hole in this thing so we can move forward”

From this angle the telescope looks like a guy wearing a Vietnamese hat and doing yoga.

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

Somewhen in there are creatures we’d really get along with were it not for the 58.71M light years between our galaxies, and the unlikelihood we both exist as simultaneous civilizations.
