Raenir Salazar posted:Do they have to be that big in space? I thought they're only that big on Earth due to interference. If so, maybe that could be another use for asteroid mining and space processing/fabrication of materials in the long term, aseembling large sensor arrays for deep space telemetry. For radio astronomy their telescopes do have to be big just because of how large the wavelengths are, though as said bigger is obviously better, to get around interference theyre located in places where there either isnt a lot of radio broadcasters or enforce a radio silence zone around (usually both). But the only serious space radio telescope proposal I'm aware of would be to place one on the far side of the moon which would block pretty much all interference from Earth

If this is part of some strategy to get more space telescopes, I am for it. Feels like it would have worked better on trump to tell him he gets to tell people about important space photos and get applause and then tell him that if there are more telescopes, there will be more photos.

I would bet a reasonable sum that the impetus for the presidential early release came from the White House, not NASA. At most, NASA might have suggested it first to curry presidential favour, but I haven't heard of Biden having a particular grudge against or really any strong opinions about NASA.

It's worth noting as well that the JWST image was exposed over a matter of a hours, whereas Hubble deep field images take at least a week, sometimes more. If we expose JWST images for longer, we can potentially take even more mind-boggling photos. It also means that we get more science out of it in general - there are a lot more people who want to use the telescopes for science than there is time for the telescope to stare at stuff. Being able to take images faster means more people get to do more research.Raenir Salazar posted:Is that what's happening with all the swirly looking galaxies and the elongated ones? Yes. There is a cluster of galaxies at the center on the ripples (note how the swirls sorta resolve into circles if you extend and connect them) and the dark matter that is clustered there is so dense that this mostly-invisible mass is bending light around it, acting like a lens.

How do the like, three remaining guys that still believe in modified Newtonian Dynamics explain that? Just a bunch of black holes chilling all together without a wisp of hydrogen?

I wonder how you'd go finding out about that, outside of keeping an eye on Arxiv. Is there a MOND newsgroup around, or something?

Is MOND in crackpot territory now? I thought there was a publication a little while ago that gave it a little credibility back, but I can’t remember what or why. If you’re a MOND guy, how easy is it to switch to something else? I assume that it would be easy, since you’re still studying gravity and probably a lot of the same things dark matter people study.

I don't think it's crackpot, just running on inertia. You can probably contrive a lot of perfectly valid scenarios to explain what we see, but Occam's razor at this point is cutting so deeply in the other direction that even if your heart leans MOND you do have to acknowledge it looks pretty bad for the theory.

MOND believers generally spend most of their time on galaxy rotation curves and/or galaxy cluster dynamics with an occasional foray into specific modified gravity theories. Most other astrophysicists pay them little attention because there's no MOND theory I know of that works at multiple scales (a random paper I found on that topic if you care to delve further), so... why bother? Anyway, JWST's view of the Carina Nebula is pretty nice: https://twitter.com/NASAWebb/status/1546877197583060993 ... but I like Stephan's Quintet more: https://twitter.com/NASAWebb/status/1546874376351612930?cxt=HHwWhIC8qZaDzfcqAAAA
