You know a star is bright when it can be plainly seen from another galaxy. A close galaxy, given, but still another galaxy.

[@kingsolo6241]

All stars you see are from the Milky Way. The closest big Galaxy to us is Andromeda. But Andromeda is still so far away that the Galaxy itself looks like a star. That is with plainly seeing with our own eyes.

[@robinchesterfield42]

Ha! Funny thing is, when I was a kid, I made up an imaginary planet, with its own map, climate, history, etc.--and it was around Rigel. ...BOY did I ever get the length of its year wrong! :P

[@raptorzeraora2632]

Robin Chesterfield how long was it?

[@robinchesterfield42]

I don't quite remember...but I do remember it was in like, the hundreds of years, NOT anywhere near the _millions_. I was like, "Well, Pluto takes like 200 years to go around the sun" (and yes, it was still the ninth planet back then!) "and Rigel is way, way bigger, so the first habitable planet would be like...maybe the fifth instead of the third? And it'd be way way further out than our Jupiter, too, so like, the year would be about...oh let's say 500 years? Yeah, that's a big difference. That'll probably be enough." I then went on to do stuff like make up a global map with alien continents, a pink sea, and a legend showing what colour meant what biome and how many miles an inch was. ...never realising that my poor civilization would probably be FLOATING IN LAVA that close in to a blue supergiant! :P (Well, I _was_ a kid, and we didn't really know any confirmed exoplanets then, and the Goldilocks/habitable zone phrase didn't exist yet. STILL!)

[@valeriouscatastros8717]

+Robin Chesterfield Your hypothetical planet can still exist, you just have to recreate your scenario and move it out further away from Rigel like in the video for there to be *PHYSICAL LIFE* like on Earth. Maybe it can be say, the 1000th planet from Rigel. Allegedly, there is a race of spiritual extra terrestrial beings on a planet around Rigel called the Iarghuns, and the Sirians from Sirius have a colonized planet there, and there may be a Reptoid planet there, but these beings are spiritual beings, not 3D physical beings like us. You simply do not feel hot or cold in the Spiritual Realms unless you are in Hell, and you do not have to eat, or drink anything physically, (Though you can) but rather, you absorb energy, (Any kind) as food. These extra terrestrial spiritual entities are basically angels and demons. A spiritual civilization around a Pulsar, White Dwarf, or Blue Super Giant would be very energetic due to all the energy coming from a Blue Super Giant. We would receive more energy (maybe not light, since it could be more outside the visible-light spectrum) from a blue star than from our Sun, that's insane! If R136a1 was at the distance of Proxima Centauri, we'd still be basically orbiting right next to the star, and be cooked even at the distance of 5 light years. These O type stars are very dangerous, but they usually form in groups, and star clusters together, like the Pleiades. They usually form closer to the Galactic Center too. So we do not have to worry about one of these star monsters like Eta Carinae just randomly showing up near our solar system and killing us. We are in a relatively peaceful "urban," or "country" region of space, in our galaxy and not the "big city" region of space closer to the Galactic Center.

[@MedK001]

Robin Chesterfield Well, if your planet's greenhouse effect is really small, then it could be habitable at those parts. Like, Mars would be habitable if it was where Venus is

[@teguenjoyer3842]

From a child's fantasy we gone to philosophy

[@twentieth_r]

The Sirius part, that's not a bug. The habitable zone is calculated from surface temperature (or, heat resonating from the star) and it's luminosity. Now... a star can be REALLY small, but have an insane amount of light and heat luminating from it... therefore, the habitable zone (though completely fictional, we would never be able to survive that far out from a star) is much further away.

[@carlahead5072]

Rob Milnes We'd more than likely freeze before we'd even get halfway out from beyond our habitable zone.

[@coopergates9680]

He does another video about the Sirius B habitable zone though. That white dwarf is still much dimmer than Sirius A, he found that Earth had stable temperatures at around only 0.09 to 0.1 AU from Sirius B.

[@alluxbr1468]

The Sirius? I noticed that immediately

[@GoogleAccount-gv7lk]

No the habitable zone is calculated just from the luminosity. Think about it, the reason red giant habitable zones are so far away is not necessarily because they're big, its because they produce a LOT of radiation, and so their habitable zones must be further away. The amount of radiation that Sirius B produces is actually quite pathetic, its WAY less than even the sun. Sirius B's habitable zone is much closer than 1 AU.

[@Observo68]

Earth orbiting Rigel in its habitable zone, at close to 40 000 AU, you said one year would take 1,7 years... suspect you misread that, Anton. Your chart says 1,75 MILLION years. Which makes more sense. ;)

White dwarfs are superhot so I would expect their habitable zones to be far out. Regardless, you should actually pay attention to where the temperatures of the Earth stabilizes at 16 degrees Centigrade, because as you were talking about R136a1 saying "where liquid water can exist" Earth's surface temperature was plummeting rapidly below -110 degrees Centigrade. You should pay more attention.

The weather on earth, when orbiting other stars larger than our sun, would be a lot more extreme because we’d be spending more time in each season and therefore the temperatures would be more extreme near the end of each season.

[@GoldballIndustries]

and Proxima B Seasons would be very short.

[@czarpeppers6250]

I actually did a spit take at the 5 light year habitable zone. That's like... if the Sun were that star it would make Alpha Centauri habitable. Granted given the lifespan of such a star any planet around it or near by wouldn't really have the time to become habitable for life before it went boom killing absolutely everything nearby.

[@cyndie26]

Here's another thing to consider: blue stars only last for a few million years, so habitable planets in those systems may have no time to develop and red stars' habitable zones may be so close to their parent stars, the only way for those planets to be habitable is for them to be tidally locked to their parent stars, which, at best, would make it very uncomfortable to live there.

Funny thing is, if a planet orbited in the habitable zone of R136a1, the massive wolf-rayet star would go supernova and live its entire life before the planet even made one full orbit around it.

damn. this is not what i expected. i thought he was gonna put earth as close to the stars as the sun so it would be hyper hot or inside the star

[@J31392]

90 percent of stars are smaller than the sun? I never knew that. That is so interesting!

[@SomeonEE123]

Yes, as most stars are red dwarves. Over 90% of the stars in our galaxy are red dwarves and their mass is usually between between 0.08 and 0.6 solar masses and their luminosities can be just 1/10000th of that of the sun

[@SgtVeritas]

[@lucerozuniga-gonzalez3643]

Hello wonderful anton this is person

[@ACoroa]

When it comes to habitable zones are the star's spectral profile and solar winds taken into account? For example, if Earth were put in Sirius A's habitable zone, would the intense UV radiation be too much for Earth's atmosphere to maintain itself? Would Earth's magnetic field be strong enough to withstand the solar winds?

[@raptorzeraora2632]

Geospatial Bluff well I guess we have to make it industruible

[@artmcteagle]

5 light years? 5 lys is around 316,205 AUs, so when we apply the inverse square law, R136a1 would have to emit nearly 100 billion times the energy of our own sun. Its brightness at the distance of the nearest star to Earth, Proxima Centauri (just over a parsec), would be about the same as the full Moon (Wikipedia). So, although it's a mind boggling powerful star, I believe that the habitable zone would be much closer.

[@YugoslavForever]

R36A1 could dominate temperature determinations for planets in other neighboring star systems! No sense in thinking about life coming about that way because this star is probably super short lived and in cosmic/geologic time it’s about to have a collosal supernova that would wipe out any life and then cool down any temperate worlds.

[@lucifaerislifeandstuff5181]

[@salsabilaayudia6429]

Hey anton,why you did not put the earth in to a neutron star(like crab pulsar)?

[@driveral1305]

The biggest problem with a long orbital period would be variable seasons. If a habitable planet could be found around one of these massive stars, there really would only be one season during anyone's lifetime, and likely the lifetime of any living organism. The tilt of the planet, any moon(s), and rotation would clearly be a major factor for life on the theoretical planet, but for diversity to develop, there needs to be variable seasons.

[@Timbretwo]

"90% in the galaxy are small warm red stars." So yeah let's get in there on a planet close, nice and cozy to melt us some ice and grow some life there. .

[@johnnycondor]

A fascinating study! Thanks!

[@GoogleAccount-gv7lk]

I think it might have been a bug. Because the distance to the habitable zone has really nothing to do with temperature, but just the luminosity. Rigel and betelgeuse both have about the same luminosity and so their habitable zone must be at a similar distance.

red dwarfs are cold compared to main sequence stars and have more flare activity in UV light and radiate infrared light so it be red shift light so red dwarfs have very narrow habital zone which greatly reduces odds of life developing.

[@TimpBizkit]

Probably orbiting R136a1 I would have thought would produce the longest year as it is so super powerful (8 megasuns) that you would need about the square root of 8 million or 2830 astronomical units of distance between it, which counteracts its mass of 300 or so suns. I am curious as to why the habitable zones are so much further away than what I predicted from an inverse square law. With the inverse square law 1 sun for 1 AU to make the planet like earth. A star with the power of 4 suns should be orbited from 2 AU. A star with the power of 100 suns from 10 AU. 5 light years is what you'd expect for something (probably a quasar) with the luminosity of 100,000,000,000 suns. Or 125,000 of the R136a1 star. Am I missing something with the calculations?
