The Closest Alien Planets

As the James Webb telescope becomes operational, we'll soon start receiving more data than ever before on the exoplanets nearest to us. The only problem is.... what ARE the exoplanets nearest to us? Today we're taking a look at our closest neighbors to see what our chances of finding alien life are close to home.

[@calsta619]

The red dwarf being more common is a dual factor, of which you only mentioned one. A smaller star requires less gas to form, i.e. more can be formed from the same material available aka more are created. They also burn dimmer but for longer than the larger stars do, therefore the ones formed stick around for longer. So more are formed, and the ones that are formed stick around for longer, giving us two reasons to see more of them

[@corrinflakes9659]

@@mtgoat179 Why are you asking me? I’m not an astronomer, physicist, etc. I literally go to school for art, space is just pretty. Unless you want a public opinion, then I think plants definitely count as life. Thing is for reference of our own history, animals evolved shortly after plants but only after fungi already did, as we are more closely related to a hallucinagenic mushroom that’ll give you a good time than the hemp that provides the cannabis. If a planet is more resembling to fungus, that counts too. But regardless, plants indicate life more as animals move around all the time, a plant is reliably stationery.

Actually, the JWST wasn't primarily designed to sus out exoplanet details. It can do some of the work, but only if that work can be done in the infrared spectrum. TWINKLE, PLATO, ARIEL, and hopefully in the future, HabEx, are specifically designed to characterize exoplanet atmospheric composition and other relevant parameters to quantify habitability.

[@Arizona_Ice]

Everyone asks “what da dog doin” but no one is asking “how da dog doin”

[@drydenstewartenterprises]

Love the Chanel! Its great to have someone finally covering the topics you do! One thing that I always think about when I hear about new planets being discovered is wanting to go and explore them somehow someway, but when you realize that the mass of the planet, also equates to the gravitational force on the planet (1 earth mass = 1 G of force) so if a planet has 4x the mass of earth, it is going to have 4 G of force on it, an average 200 lb man on earth is going to weigh 800 lbs on the new planet, so it's not like you would be able to pick yourself off the ground let alone walk around on this new planet. I am going to watch your video on habitable exoplanets next, hoping you have this in the equation in that video

[@professorracc.9780]

you mentioned how one side facing the star (tidal locking) seems to be the norm for planets orbiting dwarf stars, this is because objects become tidally locked quicker when what they orbit is closer / bigger. This is why the moon is tidally locked to the earth, but earth will not be tidally locked to the sun for perhaps many billions of years, though Venus and mercury are.

[@ronaldrobrahn8862]

[@trifectaofchris]

First video of yours I’ve stumbled across and loving the content so far! A question I wonder about the potential habitability of Proxima Centauri’s planets (barring radiation death), is what effect does the primary sun being a red dwarf have on biological bodies? I’m assuming it’s giving off less heat and light in general, as well as a creepy red glow over everything.

[@trifectaofchris]

If the distance between Proxima Centauri and A & B isn’t massive, I suppose the other stars could supplant the necessary light requirements?

Great video and good work. Like you stated, many of these systems likely harbor smaller worlds and moons that we simply cannot yet see due to our technological limitations. Even Alpha Centauri A and B almost certainly have one world according to the data. It has simply proven a difficult system to investigate.

[@zimriel]

I remember hyping the Alpha Centauri system when they mooted it in the mid 2010s and... getting burned, when they retracted their findings. (Our host might have flashed a screencap or two about the hype, but I'm actually glad he didn't, because I might have started weeping. What an embarrassment that was.) Proxima's system by contrast has held up.

[@verdi2310]

There is video in the Cool Worlds chsnnel showing that none of the exoplanets detected so far are really considered habitable. Some headlines like "new earth, earth 2.0" are just to catch public attention.

[@zimriel]

I hate to be the guy who asks "Link??" but, I'm honestly asking, I'd like to watch this. I was under the impression there was research about "Goldilocks Worlds" which claimed that K stars were better than even our G star here. Although there was some talk lately that K stars emit almost the same infrared as G stars so the "habitable zone" would likely be just another Venus zone. Anyway like I said, link plz

[@jhtrq1465]

14:34 Tidal locking can also be on a 3:2 resonnance, like Mercury or Venus, and the planet could have a (quite slow) day/night cycle, which would help to regulate the temperature on the surface quite a bit. 24:50 O and B stars are very unlikely to have any planets around, for 2 main reasons. One, their intense light and UV radiation quiclky blast away and ionize the protoplanetary disk around them, makin acrretion of materials very difficult, if not impossible. And lastely, their very short lifetime (especialy for Early B and O stars) is incompatible with the time necessary to form planetary bodies.

An amazing channel. Not only do you not use the words Shocking Discovery in the headline but it's your real voice and sartorial elegance. More importantly, the question you raise are interesting. How would a being living in a twilight zone measure time? And how does the age of a system effect things? I think Epsilon Eridani is a quite young system.

[@shoam2103]

Sartorial. 🤔🤨🧐

[@espasmemuscular]

All these types of videos should start with the disclarmer "life as we know it". We know so little, it's best not to make too many assumptions about how life can or can't occur out there. Also I can't image how it would be to live in the moon of a gas giant, and what crazy mythos might emerge from sentient races living in them.

Likely is an important part. It may be what you said but it is probably not. Also, it is too close to its flare type star.
