JWST is a piece of trash. If I happen to get lucky and step in something amazing does that make me amazing? I was looking at some babe coming out of the shower the other day who left the curtains open and man her curves were amazing. If I then said dude this telescope is amazing then it's merely a turn of phrase. What I actually mean is that it allows me to access that which is actually amazing. Whatever possibilities it may unlock a key to the lock at the end of the day is merely a random shape made out of every day iron only valuable because that shape happens to have been arbitrarily chosen to be the one that unlocks the way to the actual valuables. If there's nothing inside the chest then it's nothing but a cruel joke. A bit like your mother what what.

Within weeks, Corona Borialis will go nova, as I understand it. You might want to do an episode on what has lead up to this, and the long term expectations after its over. My wife and I will certainly be on a nearby mountaintop to observe this as much as we can before it fades away in a couple or three weeks. Thanks for keeping us informed on so many things. When I'm short on time to look at things in detail, I know you'll sift out the best parts for me. It's why I've been a sub for years now. 👍

@stargazer5784 4 күн бұрын

T Corona Borealis is a recurrent nova that experiences increases in brightness of about 7 magnitudes roughly every 80 years. Your enthusiasm is heartwarming for an old astronomer like myself, but don't expect anything spectacular, as it will probably only come up to about magnitude 2 or 3. Unless you know where to find it, you could easily miss it. The supernovae that Anton is discussing here today are totally different animals that are orders of magnitude higher in total energy output. There have been 4 naked eye visible supernovae in the Milky Way in the past thousand years. One of them (I think it was Tycho`s star, but maybe not) was bright enough to read by at night and visible in broad daylight when at peak luminosity. It remained naked eye visible at night for about 15 months. Look up the supernovae of 1006, 1054, 1572, and 1604 to check me on which one it was. I don't cheat by looking things up before posting like some others do. Good luck and wishing you clear and starry skies.

This is a perfect example that the universe is not uniform in density. I am sure that if you were able to measure it, that gravity around a supernova would be significantly diffent from deep pace where there is nothing around. We have no way to determine the overall gravitational effects on light over long distances because of these facts. We have no idea how much impact matter between two points has on the ligh traveling through those points!. It is probably being impacted by orders of magnatude which would suggest we dont know shit about how far things are away from us.

2 questions. 1. Is the velocity of some of this ejecta material great enough to achieve "escape velocity" of its parent star? 2. Is some hydrogen formed (frome heavier elements) at the super nova event or is all the ejecta heavier elements?

@geoffstrickler 4 күн бұрын

1. Yes, the ejecta can exceed the escape velocity of the remnant, and it usually does. 2. The ejecta will include some remnant hydrogen and helium along with lots of heavier elements.

@markusmaximus629 4 күн бұрын

@@geoffstrickler Let me further clarify question 2. I saw in another video, that the iron at the core of a dying star, is impacted with so much energy from the harmonic of the collapse, that that energy is reabsorbed by the iron and transformed back into hydrogen. It seem incredible but possible. Now, if this did not happen, then all of the ejecta is heavier elements which offer little prospects for new stars. New stars need hydrogen. The black holes are obviously recreating hydrogen as part of their process, but that is far from the star forming regions we see. Sp I guess the question is, how much hydrogen do we detect in the ejecta?

@geoffstrickler 4 күн бұрын

@@markusmaximus629 can’t speak to that, it’s certainly conceivable. But no star “burns” all of its hydrogen, nor it’s helium. Helium fusion starts when the hydrogen level drops too low (~25% IIRC, but I could be off on that), likewise, the next stage begins well before the helium (and hydrogen) are exhausted, repeat until nova/supernova/core-collapse. So, there is always a whole variety of elements blasted out in a supernova. Whether any notable percentage is fission products is outside my area of knowledge.

@badhatharry4323 4 күн бұрын

Iron is there mostly in the form of single atoms. New molecules form when interstellar gas had cooled off sufficiently. And indeed - any larger body is the consequence of clumping. Starting from little over-densities in dust clouds, gathering material by movement and eventually self-gravity if enough mass had accumulated.
