There are approximately 1,400 stellar systems in space within the radius of 50 light years from the Solar system. Some of them are multiple and contain two and more objects, which makes the overall number of our stellar neighbours over 2,000. These are all sorts of stars, from dim red dwarves to dazzling giants whose temperatures are beyond our imagination. The incredible scale and great abundance of space objects in all their diversity can’t but amaze. Life’s too short to give account of each and every one of them.

As I recall, there are only a few dozen ‘earthish’ planets in the habitable zone out of a few thousand exoplanets discovered. It is possible, though, and even likely, that there could be giant earth sized moons around some of the Jupiter sized exoplanets that we cannot detect.

[@TheNoiseySpectator]

I would be skeptical of that. We cannot detect objects as small as "Earth sized" planets very well.

[@76rjackson]

I think that's likely to be true. We have seen a disproportionately large set of Jupiter like planets. Jupiter and Saturn both have large and diverse retinues of moons so it is reasonable to infer that there will be earth sized moons around some of the larger specimens.

[@TheNoiseySpectator]

@@76rjackson What, around planets the size of Jupiter or Saturn? Absolutely not! The largest moon in our solar system, Ganymede, is 3, 273.38 miles across. Earth and Venus are more than _double_ that size! Let's just say such a body would be in the range of seven to eight thousand miles in diameter. Something that size would _tear apart_ something like Jupiter or Saturn! 💥

[@TheNoiseySpectator]

However, I for one, have no doubt there are "Earthish" sized moons somewhere. But they would have to be orbiting planets that are so much bigger than our large gas giants, that I doubt they could not be in the same classification! BTW, a bit of trivia; The Earth is the largest _solid_ object in our solar system. If you combined Mercury, Venus and Mars, they would still equal only about 99% the size of the Earth. 🌎 = 😀👍

[@inthefade]

@@limiv5272 I recall watching a video (probably by Anton Petrov) about a paper that proposes our solar system is in some sort of nebula. It is incredibly hard to detect if we are, or not.

[@TurtleFL]

If there are, detecting them would probably be extremely difficult, because Oort Cloud material is probably as cold as the interstellar medium itself, reflects virtually no light at the distance it is from the Sun, our parent star, and does not have enough mass in it to exert any detectable wobble on the Sun as would be observable on our equipment parsecs away from it.

[@TurtleFL]

So, I imagine detection might be remotely possible, if it emits any observable radio wavelengths from electrostatic or electromagnetic activity from any physical processes going on in celestial bodies orbiting those distances around their stars. Not likely to be much of that, either, but I think it's a long shot possibility.

In fact, every star in the stellar neighborhood you have discussed is far below the size threshold for going supernova; including Sirius, Altair, and Vega.

[@davidunwin7868]

Red Giants like Arcturus don't go supernova to form a white dwarf. A supernova is an implosion caused by core collapse when the star fuses elements into iron. Once that happens, the fusion stops and the outward fusion pressure no longer supports the stars mass against its own gravity. The mass collapses in on itself, and rebounds off the iron core in an explosion. The pressure creates either a neutron star or a black hole. In contrast, a red giant doesn't t have the mass needed to fuse heavier elements, so once it's hydrogen fuel is depleted and begins fusing helium, it swells up into a red dwarf, and starts to "sputter" like an engine running out of fuel. Gradually the outer layers are thrown off in the pulses and what's left behind is a planetary nebula and a white dwarf star, which was the core of the red giant.

All completely unsuitable. Red dwarves have enormous mass ejections that would fry anything on a planet in the goldilocks zone. Very few stars are stable in their emmisions. Small G type stars like the sun are fairly rare but they are stable enough to not endanger life very often.

In the case of Ross 128, as a red dwarf, it’s a lot less active than these other stars like Trappist-1 and Proxima Centauri.

What kind of gravity on Ross 128-B? Being 30% larger i assume it would be tough to even stand or have the strength to walk? Complex life at best would be jellyfish or squid-like creatures with those kinds of pressures

[@NobleDankLord]

Not exactly accurate. See, you are trying to equate our prespective of the pressure of evolution to other planets. The beauty of evolution is that organisms adapt to the enviroment rather than the other way around. They can have giant creatures or microbes for all we know who can adapt to the pressures.

With a mass barely more than that of the Sun, Arcturus will never go supernova. Objects up to almost 8 times more massive than the Sun will always go out with a whimper. Objects more than 8 times more massive than the Sun however. Well, boom.

I’m speaking on how does one have any type of knowledge of an object that’s light years away

[@beta_cygni1950]

You know, you COULD'VE googled this. We can know A LOT about these objects in several ways. First is through the science of spectroscopy. By examining the emitted light, we can know the chemical composition & what its made of. All elements produce unique spectral lines in their emission spectra... Its like the element's unique "light fingerprints." So by examining the light and breaking it down into its spectrum, we can know exactly what its made of. Also, we can know things like the object's mass & size by its orbital period, etc. We can know how far the objects are from us through a bunch of ways. For example, through trigonometric parallax (which is basically the same method that surveyors use in construction). Google is your friend. Use it.

I wonder, if we weren't in a rather sparse region of our galaxy, that in turn is on the edge of a supercluster, that in turn is looking out across a supervoid... would we be able to see even a fraction of the stuff we see? I mean, the light pollution from being in a dense region of a dense region within a dense region would limit our deep-space views, no?

[@PhilTParker]

From what I understand, our Earth lies two thirds out on our arm of the Milky Way galaxy. I’m under the impression that our region is indeed “rather sparse”, relatively speaking. If we were closer, such as half way from the center of our galaxy, I wonder if we would find ourselves in the middle of a much denser area in terms of the number of stars that exist near to us, filling our night sky with luminosity. Perhaps because more stars would be closer, we might even see more of their colors directly, and perhaps more easily see nebulous objects also.

I saw a diff channel claim our galaxy supercluster does in fact reside in the largest supervoid in the observable Universe, yet I hear from other vids thaf Bootes Void is the biggest.

Excellent video. The Universe is designed for the creation of life, it's everywhere.

[@bigedslobotomy]

There may be bacterial life everywhere, as it is very hardy; but advanced life (and intelligent life) requires billions of years of stable environments. The star can’t throw X-ray or gamma ray flares. It is helpful if the planet has a large satellite (such as our moon), but ours arouse from a very unlikely collusion between us and a mars sized planet - and not a direct hit either. It was an oblique hit that tore off enough material for the moon. Even then, advanced life may not flourish, as there were several times during our history that life was nearly extinguished (such as the “snowball earth” event). There may indeed be other intelligent life out there, but it would be prudent to be skeptical until it is truly found. Science fiction movies have conditioned us to think that intelligent life is plentiful, but science requires proof, not fantasy.

[@mikoto7693]

Oh I don’t know. With millions of stars in our galaxy, most with planets around them, and then there being millions of galaxies the sheer numbers would seem to favour life occurring somewhere else. Alas with distances being so long it’ll be a long time before we meet any, provided both species do eventually figure out FTL.

If Ross 128 is a Red Dwarf, then wasn't it once a normal star? If so, then wouldn't Ross 128B have once orbited Ross 128 at a distance closer than Mercury is to our sun? If so, then Ross 128B would seem to not have the building blocks of life since the planet was once baked like our planet Mercury.

[@chippysteve4524]

Really enjoy your vids Kosmo! Just one suggestion- you shouldn't say e.g. "3 times as small" or "5 times lighter". We know what you mean to say but it makes no logical sense and therefore is logically meaningless. e.g. what does "1 time smaller" or "1 time lighter" mean? - it's meaningless. Far better to say "one third the mass" or "one fifth the size",both of which make sense. Keep up the good work! :-) .

[@loopernoodling]

Thank you! I thought I was the only one who found that weird. It's not just here - that usage seems to be in most of Kosmos's videos. Multiplying something usually makes it bigger, not smaller!
