Supernova?

32058 Isn't there a way to emulate black hole effects too, by creating artificial black holes in a lab? Absolutely. :)  Analogues of black holes (in particular, demonstrating effects analogous to event horizons) can be made with fluids.  Set up a fluid flow where within some region the flow speed i...

Sci-Fi (and other genre) Movies & TV Series

I too would put Superman in fantasy instead of sci-fi.  Sci-fi can have a big range in terms of hardness, but the key difference from fantasy is how it explains how things work. Superman flies because -- I don't know how Superman flies.  He just does.  It is a convenient and ill-defined magic. It is...

32053 Planck evidence for a closed Universe and a possible crisis for cosmology My take is that the most likely scenario is that the Planck 2018 power spectrum data do not actually indicate a positively curved universe, because if that is the case then discrepancies between other observations becom...

Supernova?

They're emulating a few of the effects of supernova explosions, specifically in how an expanding shockwave interacts with a thin medium around it.  Some of the images they captured look remarkably similar to real supernova remnants we see in space.  You can also get this effect by, say, detonating a...

Did I just see a guy yelling "screw you" while firing a machine gun at Jupiter?



I think I need to see this movie.

Extraterrestrial Intelligence Thread

I think if we were alive at the time of the KT impact event, or the Permian-Triassic boundary, we'd have very negative views about the situation, despite them being natural events. :)

y3SrlI5Ivb8 Abstract: To date, Hubble has played the definitive role in the characterization of exoplanet atmospheres. From the first planets available, we have learned that their atmospheres are incredibly diverse. With HST, JWST, and TESS a new era of atmospheric studies is opening up, where wide...

SpaceEngine TODO

Wow, those are incredible simulations.  Surreal.  Now I dream of seeing the Earth-Theia impact rendered this way as well -- presumably much harder than for asteroids, but maybe it will be possible in the near future. :)

31560 Hey Wats, I wouldn't mind hearing your opinion on this, as crazy as some of it sounds: Sorry for forgetting to get back to you on it.  It's a pretty good video as usual from him.  I'm not quite sure what you'd like me to talk about with it, though.  It is kind of a mashup of simple explanatio...

Astrophotography

31766 20.25 hours That is an impressive integration time, and the result looks amazing! Also (and maybe you've already considered this or have a different philosophy), it might not be a bad idea to put watermarks on your high-res images.  I'd hate to have someone easily steal and profit from your v...
