We've briefly discussed exoplanets and some methods that we can use to detect them, but we haven't yet looked at any specific ones. You may have heard of the TRAPPIST-1 system that was discovered recently, and for good reason, it's a very exciting discovery! Let's get a closer look at this system on Space Engine and see just what makes it so special.

Imagine if both Trappist-1 d and e end up habitable and develop sentient life at around the same time. How crazy would it be live on a planet where you can look into a telescope and see nightlights of an another civillisation.

He did a very good job. And as he stated there are a lot of exoplanets found around red dwarf stars. Do note the temp he gave. So when some idiot tells you that all stars are white. And so they do all produce the full electromagnetic spectrum they all have a color sequence Our star is a yellow star. with around a 5000 K temp. But you also need to study it on your own. To see the full story. It is an incredible field. When i was 10 i started to grind my own telescope. and in doing so got a break most kids do not get. in 1973 i met an actual cosmologist and he took me in and i got a two week stent at a 200 inch monster. After that it was my field the one i would follow the longest and actually throughout my life. And one dad would learn to regret using his words against when it came time for college. It is a JUNK SCIENCE he would not help me become a cosmologist choose something else or no college. So i chose medical science. But then in 2012 i met Miss Aller. Christine Aller 3 generation PhD in cosmology. I did not say much to her just a small comment and i described my telescope to her. Now her parents would know about this telescope and its fate. the primary was cracked during transport. taking the amount of the largest at its time telescopes from 5 to 4. Her and her family surrounded to more club president. All she could say about me was ( oh that is some new member that for some reason knows all the deep sky objects without a map ) the surrounded my family and found out why i did not become a cosmologist even though i more than qualify as one. In fact i am one. 3 different groups of cosmologist fell to the same fate. Until the president could not stand how i could stop a lecture in its tracks just by saying something It is like the last one talking about dark matter. So what did i do? mention the bullet super cluster.

It's probably been so for a long time, but I've recently discovered the TRAPPIST-1 system exists within the star map of Stellaris! All 7 planets are present in the system, and TRAPPIST-1d through 1f are habitable planets of three preset climate conditions (Dry, wet and cold), which is really damn cool.

It would also depend on the atmosphere--a high greenhouse effect could quite easily let the planet retain enough heat to have liquid water. Another possibility could be that the outward side of the planet is frozen, but some or all of the "sun side" gets enough light to be habitable. And when talking about "habitable zone", bear in mind that two of the best local candidates for extra-Terran life (Enceladus and Europa) are both well outside of it in our solar system.
@PeterDebney
@PeterDebney 8 ай бұрын
Tidal forces will add heat to the planets or lock them to the star (like Earth has done to the Moon). The expectation is that most or all of these planets are tidally locked, so they won’t experience any tides as a result.

Think about what their lore and storytelling might be like if a civilized species evolved along the terminator line of one of these worlds... where this giant vicious red ball of fire loomed on the horizon ever-still... and burned and scorched the lands beneath it, with other worlds flying by like slightly smaller moons and occasionally traversing across this massive red fireball as these ethereal black orbs.

1:11 that means nothing at all, since all stars are also made of gas, and with increasing mass they become able to hold significant amounts of plasma, or unformed matter as a protium-Neutron-Electron soup, which is mixed with infused hydrogen and helium-3. Except this star is too small for that, and hence only primarily uses the hydrogen-> helium-3 process. It would still be too small (due to being 0.089 solar masses, far under the 0.3 masses needed) for any CNO fusion to happen and too big that deuterium would be a significant factor in fusion processes, like that is in Brown Dwarfs (deuterium is the primary indicator, Hydrogen’s passive aggressive isotope cousin, and in some cases like Jupiter magnetic energy as well as meaningless amounts of deuterium fusion can give off radiation. Hence TRAPPIST-1 might be one of the smallest functioning stars we know of, and likely one of the longest lasting.

What I would give to see a clear-sky view while in this system. Just a rough estimation, but I think the planets would appear about as big as our moon to us at their closest approaches to each other. (Probably not as bright given the likely lower albedos and cooler thus redder star light, but still, it would look awesome!)

The system is too young for any of those planets to have oxygen atmospheres. Plus the flaring from the star probably strips the ozone column of any planet with an oxygen atmosphere, or will when they evolve. So look for microbes in the seas if there are seas present, but no metazoan life.
@claudel.mertzenich331

Barton, the question of oxygen in the atmosphere is very important, as you seem to understand. Currently, to the best of my knowledge, there are no known planets with a significant amount of oxygen in the atmosphere; since oxygen is very reactive, any oxygen that might have existed in early non-earth planetary atmospheres has long since reacted with metals to produce metal oxides, thus eliminating oxygen from the atmosphere. Photosynthetic life on earth has produced the oxygen in our atmosphere, so the lack of oxygen elsewhere strongly suggests that photosynthetic life as we know it does not exist there. I look for the day when oxygen will be discovered in the atmosphere of an exoplanet; that will certainly be one of the greatest discoveries of all time because of the strong suggestion that photosynthetic life exists on that exoplanet.

Well you don't really need oxygen for earth-like life. Sure it could still be carbon-based, bit it could have evolved to use another gas, like nitrogen or methane for example, or even carbon dioxide. Life is very flexible. Basically, life needs water, an energy source and nutrients. Sure, ozone in the atmosphere is needed to protect life from radiation, but life could have evolved to tolerate high levels of solar radiation. You just need a few individuals that are more tolerant or better adapted to higher levels of radiation. Over time you have life that's adapted to those conditions. If it's bacterial then this process can happen very quickly, possibly in just a few years.

Fun Fact: Trappist is an order of monks that brew beer. Most trappist beers are made in Belgium and this solar system was discovered by Belgian scientists, so they named it TRAPPIST, after the telescope they have placed and used in Chile: Transiting Planets and Planetesimals Small Telescope, or TRAPPIST for short.
