JWST in Different Spectra, Milky Way Losing Stars, Mystery of the Sun's Corona | Q&A 277

🦄 More Q&A in the Overtime Audio:

Does building more JWSTs for different parts of the spectrum make sense? Are star types predetermined at their birth? Can you cook a pizza on the Sun? Why is the Sun's corona hotter than its surface? Are there binary supermassive black holes? Answering all these questions and more in this Q&A show.

I wonder how big that array of LISA satellite has to be.

[WillDa]

my man just invented the Pizzabitable Zone, absolute genius

[Mike-ez]

79 Jupiter's to make a red dwarf. That really puts into perspective how big stars are. Especially the massive stars hundreds of times the size of our sun

[ferranferran]

*Of course* we should have space radiotelescopes. That would be the first step to an interplanetari interferometer.
Take care.

for 04:07 i have an addition: there's not just a minimum mass for hydrogen fusion, but minimum masses for fusing other heavier elements, too!

according to my own research:

- bodies with at least 13.6 jupiter masses can fuse hydrogen into deuterium, aka "heavy hydrogen"
- bodies with at least 80 jupiter masses (or 0.076 times the mass of the sun) can fuse hydrogen into helium
- bodies with at least 0.4 solar masses can fuse helium into carbon and oxygen
- bodies with at least 8 solar masses can fuse carbon into heavier elements, like neon, magnesium, and sodium
- bodies with at least 10 solar masses can go supernova, which allows them to briefly fuse much heavier elements at the end of their lives
- bodies with at least 12 solar masses don't have to wait until the red giant phase to fuse heavier elements than hydrogen: they can fuse helium while in the main sequence

of course there's more information than that, but i'll leave that to you to search up for yourself!

I can see a Fraser in space cooking show going

[larscarter]

The source of the fire is always cooler than the energy of the fire produced.😊

[longshot]

Whew. I saw the thumbnail and immediately thought "Not JWST too."

[tommy-erhh]

Thanks for explaining the corona temp.

[MrMalidis]

Hi !
Just randomly bumped into your amazing channel.
So my question is: "Is the Big Bang a result of collision of 2 enormous black holes???"

[InssiAjaton]

With the horrendous temperatures of the solar corona, the peak of its radiation would be FAR ultraviolet, i.e. not visible. I am pondering if what we see is just a tail of the continuum? Also, maybe the earth’s atmosphere filters or converts some of the corona radiation back to visible range?

[Raz.C]

I can picture it now: We're flying through a stellar nursery and we hear a voice booming at us from one region of the nebula "When I grow up, I'm gonna be a type-A Hot White star!!" As we fly away, wondering exactly where that voice came from, we notice that the same region of space seems to be humming the "Ugly Duckling" song...

[PaulShanley]

15:03 that kinda looks like the Magellan radar images of Venus! Great b-roll choice, Editor!!

[meaves]

How do we know it took 370, 000 years from the big bang, until the light from the cosmic microwave background was released?

[deltacx]

1:54 who knew something designed to be maintained stops working when you don't maintain it?

[AlterKnochen]

But why JWST versions? In Starship you can put a 9m Mirror, now you have a "Starlens". 🤩

[davesatxify]

I like the new stellar classification system Fraser. Ludicrous Blue Supergiant

[GentleBen]

If we dotted the earth with thousands of radio telescopes could we get a "high res" image of a black hole?

Thank you for the hard work you guys do on this channel. It means the universe to me.

[jonnylightbody]

Through the key hole is close tho. Biggest object to dip under our communication satalites we know of

[Stegibbon]

I think a star does "know" what type of star it will be when its born. If we take the beginning of fusion and the creation of the solar wind to be the birth, they can't get more massive after that without collisions/interactions with other stars/stellar objects right? Since the wind blows the hydrogen outwards?
