So interesting and curious. I wish i followed thru and became an astronomer.

The hell is an acre-foot?

Checking the wiki page on it.

There is a probe scheduled to launch this year that should reach it in 2029.

So we'll eventually have much more details on it.

It's possible. Impacts happen, Soyuz isn't especially well shielded, and Soyuz docks to the "front" of the ISS (the side that faces prograde, into the direction of travel and therefore into the direction where you expect to find high energy stuff to hit)

... Butttt... While the ISS is much better protected and it's entirely plausible that it's not damaged by hits that hurt Soyuz, someone should still notice impact scarring even if the impact has no effect inside the station, and the Soyuz is a small part of the profile of the station - If Soyuz and Progress (same form factor) each take one hit, you'd expect the station to take.... At least five or six, maybe? Just a guess, not a measured statistic... But you see where I'm going with it.

Russian spacecraft getting hit makes sense, only Russian spacecraft and not the station they're attached to is kinda suspicious.

That said, in the interest of perhaps undue (the Ukrainian half of my family would definitely agree it's undue, but that's not how math works) fairness to Russia - Two is not a very large sample. Just because it's unlikely doesn't mean it's out of the question - After all, people have won at roulette before, and likely will continue to.

I see stars in lots of images taken from space. See: Hubble, JWST.

All they know is 16 Psyche has a high density. The earth and 16 Psyche formed eons ago. Some speculate 16 Psyche is the core of a planet that was hit hard in a collision and blew off the rocky stuff - high density might be metal rich. Most common core will be nickel iron with some chrome with a scattering of other metals dissolved if the original planet was a larger. Earth has undergone billions of years of hydrothermal subduction and hydro thermal fluid transport from the deep crust driven by the water/CO2/SO2/Arsenic/silica etc. This hydrothermal fluid is lighter than the basalt, and gradually extracts gold as well as copper zinc etc into the fluid. When it gets near the surface the water/CO2/SO2 leave the fluid as gasses - some stay as carbonates/sulfides/silicates and they form layers - often around volcanos. In deep water they emerge and form nodules - which we can extract metals from. If 16 Psyche's host planet was too small for this = no metal concentration occurred. It waits for some laser bursts to the surface to do spectral analyses to know for sure. Psyche 16 may well be covered very deeply with waste rock gravitationally attracted to it that make surface analysis useless.

600 billion litres. By the time we use that we will be able to reposition a comet for resupply.

Thank you for humbling me.

I have no idea what over half of the terms you used mean, and I used to think I was smart.

Appreciate the lesson lol

Well, publishing in Nature is actually interesting because it has a 50% retraction rate over a longer period of time. They’re an interesting journal because it’s known for taking the stance of “we would rather be sure to be the ones to publish the highest impact papers of all time even if we know a lot of these won’t stand up to the scrutiny of the scientific process over coming years.” Hope that makes sense.

Like Hades opening the Gates for the titans type of event.

Couldn’t have said it better. Thanks for stepping in! :)

You are right. It orbits in and out of Earth's shadow. But at L2, that's the most stable compared to the other Lagrange points.

This particular event did not have all gravitational wave detectors online. This means the uncertainty area is really big (aka a quarter of the sky). If you have all three detectors online as once you can get it to a much smaller sky area (~100 square degrees), as well as much more precise distance estimates.

ELI5 plz, why is this a big deal ? What can be concluded from this if accurate

The moon isn't perfectly spherical

Magnetars. We have traced some FRB-like signals to a magnetar within our own galaxy so it’s pretty convincing a lot of them are created by even higher energy magnetars, IMO.

I feel that then begs the next question which is if ALL FRBs are created via the same mechanism, but I’m not sure we have a convincing answer there yet.

Or reptilian overlord droppings

We couldn't mine the moon fast enough to affect the tides in any appreciable timescale

It wouldn’t make sense if it was only on the interior of the roid. It would only make sense if it was inside and outside of it.

I mean, look how quickly we burned through the earth's bountiful resources.

this is all sci-fi. no such thing as a stupid idea! only limit is current technology. but from a physics p.o.v. all could work xD

JWST isn't in the Earth's shadow. It orbits L2 to keep getting power to its solar panels. The imager is pointed away from the sun at all times and protected by its sun shield.

Plus, if you don't build it within the acreage confines of the well-watered cornfields, Ray Liotta and them won't come.
