What Are Supergiant Stars?

[@pleaseinsertaname1266]

I'm in 7th grade and I'm studying the planets, the stars, the solar system etc. And it's my favorite thing I've ever done in school, I think I found my passion

[@Cosmoknowledge]

That's really awesome to hear. It's going to be the most humbling and character-building experience. Go on! ❤

[@IAmNoeyes]

My handle is the name of a Black hole.

[@drakemcfee9138]

You live your dream and be grateful you've found your passion. Don't ever let the people inthe hard science tell you that astronomy is a useless field, it's got no practical use. I certainly regret letting people talk me out of it since I needed a job that actually paid the bills. While I pursue it now I'm way behind. Oh and my answer to people now who say that it's got no purpose. To have at least one more moment of pure wonder.

[@tinkmarshino]

Betelgeuse has always been one of my favorite stars in my favorite constellation.. It has been misbehaving lately.. a supernova would be cool to see.. thanks Ardit..

[@Turd_Emperor]

Well there's a high chance its been dead for a really long time, so it most likely already went super nova long ago. We just need to wait for the light to reach us, which might take a really really long time. So we might be dead by the time it reaches. But yeah it would be cool to see.

[@Apaleutos24]

Well, not only Betelgeuse might have exploded but also Rigel might have entered its red supergiant phase already and as a fellow commentator said: "the light hasn't reached us yet"

[@tinkmarshino]

@@Apaleutos24 Well lets hope it hurries.. I am getting very old and don't have a lot of time left to see it!

[@Apaleutos24]

@@tinkmarshino it hasn't yet. I said "it might" but chances are that it hasn't yet and estimates the next 100,000 years. Who really can tell...?? Only a bunch of neutrinos detected here in Earth, will give us a window of a few hours prior to the supernova explosion.

[@tinkmarshino]

@@Apaleutos24 oh well.. such is life eh?

[@NErDy-pr1jf]

Supernova don’t leave nothing behind. They core remains as either a neutron star or black hole and the outer layers can make a little nebula

[@ejmtv3]

Well you said it yourself. They leave a core and nebulae

[@lloydtucker5647]

I think he's referring to orbiting objects such as planets and moons that were within the expansion radius of a star going through the supernova process. Though I'm not sure if objects that are not burned up still orbit a neutron star. I think there's a black hole at the center of our galaxy.

[@ECHOCHAMBER.BAMBI.]

Yes

[@mattorr2256]

@@ejmtv3yea also countless amounts of new elements scattered throughout interstellar space until they eventually find a gas/dust cloud or any other celestial object. They leave a lot behind by producing so much with their ability to launch those elements extremely far distances and “seed” the interstellar medium with them.

It's incredible how we can see a red super-giant star, Betelgeuse from our naked eye.

[@dennistafeltennis1190]

My favorite stars.

[@dreamypupper4080]

What about hypergiants (the stars with the largest diameters)? Like rho Cassiopeia? Or Stephenson-218? Or UY-Scuti? Also, even though hypergiants are the largest, they aren’t even close to the most massive. The most massive star is R136a1 (around 150~ solar masses)

[@Cosmoknowledge]

Hypergiants are a very loosely defined term. They could be just large supergiants.

[@xwreth]

I wanted to ask what is Hypergiant?

[@MuhammadZeeshan-zh4wy]

Sk 69 202 is an example of a blue violet supergiant estimated to be around 100,000 to 80 times the size of our sun with a luminosity of about 5,000 times the luminosity of the sun she died in an explosion called sn 1987a

[@YohanesKebede-o9h]

Amusing star

[@AvangionQ]

Supergiants aren't the most massive. They're the end-stage among the most massive before supernova/hypernova. The most massive stars are 150 solar masses.

[@IAmNoeyes]

I have a thought about stars, I have dreams of black holes, I think of the space between , the Vaccum, Dark matter . I think in shades of blue and red , my thoughts of space are the space inside my head resbleming, we must live in the dark in order to see the light once more .

[@6QMIIV]

What is the average age of a supergiant star?

[@Cosmoknowledge]

From hundreds of thousand up to 2-3 million years.

[@blizzyblaze97]

So wouldn’t that make blue giants bigger than red giants? Since blue giants are 25x the size of the sun and red giants are 8x the size of the sun?

[@Cosmoknowledge]

Yes.

Hypergiants are essentially supergiants. A hypergiant means a very large supergiant just like a hypernova means a very large supernova.

[@Barba72Simon]

It's safe to say, these supergiant stars are practically killing themselves.

[@Cosmoknowledge]

More or less, yeah.

[@CinemaAgricultural]

it's kind of like what you humans do your cells divide to replace dead cells over time those cells DNA become damaged witch results in a less efficient body and then death. So, at the end of the day everything that is alive is slowly killing itself but is that a bad thing does that make everything pointless? I don't think so even if everything dies that doesn't make living pointless even if you don't have an effect on what will happen 50 million years from now that doesn't mean that you existing left no mark maybe you didn't do something massive. But you don't have to as long as you had a positive effect on the area and people around you don't need to change the world nor try to build a great device. If you make the generals area around, you a better place than I would say you as a human lived a life that was worth something. and the same goes for us stars.

I think I'm starting to get astraphobia the more I learn about space if not for the sheer mass and craziness that goes beyond our solar system but the fact how things work and how they began in the first place that keeps me up at night I'm not even worried about other intelligent life and what they may want to do to us if they ever come to our planet if they're not already here that pales in comparison to all the other s*** similar to how I have a slight case of Thalassophobia wondering what the f*** is below our surface
