Are These Planets Found By TESS Better Than Earth?

Are you ready to explore the exoplanets beyond our Solar System? Join us as we take a journey through the latest discoveries of the Transiting Exoplanet Survey Satellite (TESS). We'll learn all about the conditions necessary for a planet to be considered habitable and examine the most important discoveries of TESS. From the super-Earth of HD 209-458 B to the mysterious Kepler 438B, let's get started!
( roll intro)
The search for exoplanets has been a source of fascination among scientists and the general public alike. With the launch of TESS, the Transiting Exoplanet Survey Satellite, in 2018, scientists have been able to identify more than 10,000 potential planets outside our solar system. For a planet to be considered habitable, it must have water vapor in its atmosphere and be within a certain temperature range. It must also have the right amount of gas in its atmosphere for rings to form, and the right amount of sulfur content for liquid droplets to exist.

A planet... 600 light years from its star?
Was there any.... proofreading phase, by any chance?
And not convinced that a planet with 30x the gravity of Earth would be "tolerably habitable".

[mikeharrington]

Exoplanet mass is yet another important factor frequently overlooked by such channels in attempting to find an exoplanet suitable for human habitation. Anything with a mass of more than 1.3 times Earth is gonna be extremely physically testing for humans to walk on, or to a perform the wide variety of tasks, maneuvers we are normally accustomed to. At 1.5 x Earth gravity a 200 lb man or woman would weigh a relative 400 lbs. After a, say, 6 month spaceflight an astronaut is likely to be weakened physically & 1.5G would then put strain on the heart immediately on starting to walk

[mailasun]

7:10 Kepler-62f has 1.6X mass of earth. 7:33 Kepler-62f has 3.5X mass of earth… you can’t be both! Pick one!

[Spillers]

What if it was just like earth but maybe 40, 000 years ago before humans were so active and you had more green on the planet?

[simonagree]

I guess the best uses for this kind of study are, in order, general knowledge of the universe, sorting out where to point SETI, and providing imaginative fuel for science-fantasy and fable.

[mm-dwrr]

It's amazing what permiations and computations such scientific discoveries are ushering in. 🙊

[NealAkins]

There could possibly be people on those planets and we would never know it until actual planetary exploration

[tjkaz]

I am insanely curious of the source of the facts provided, so I will know what NOT to use.

[JohnRandomness]

Pardon me, what's with 100 K and 60°F? "Which is still well below absolute zero." You really need to proofread your script.
Much closer to the star than Neptune is to the sun, by a factor of 30? That makes it about the distance from earth to the sun.
2.3 Earth masses? 30 earth gravity? So the planet is smaller by a factor of 3.6? And 30 earth gravity is relatively bearable? Um...Kepler-62f orbits in the habitable zone? Then is outside its habitable zone?
I've already seen comments on a planet 600 light-years from its star. But as an aside, for the Sun in its stellar environment, one light year is about the maximum distance any object can be bound to the sun. Perhaps a star outside any galaxy with very few stars within 10000 lightyears away, might be able to hold an object 600 light years away, but its temperature is going to be close to the CMBR temperature, 2.7 K.
10:30 An asteroid with a mass below 445 earth masses?

On the one hand, I would define the habitable zone of a star, along with the other definitions, to be far enough away as not tidelocked or in a rotational resonance with its orbit. On the other hand, microscopic (single-celled) life doesn't need water. It needs carbon, hydrogen, and lightning bolts or photochemistry to break up the molecules containing carbon and hydrogen. They can recombine into more complex molecules, amino acids and the like.

[jamesleatherwood]

8:17 "is an exoplanet 600 lightyears away from its star, located in the habitable zone." Me thinks either your script got messed up and you were trying to say 600 light years from us, or thats a star so massive it aint even been theorized yet, to have a habitable zone that far away from itself. :P im just giveing you a lil hard time. Keep up the fascinating and great work. :) good vid

[EvilJ]

lol, how tf is 30 times Earth gravity "Relatively bareable"?

[NicholasNerios]

The question is, if we do travel millions of miles to a distant planet that is habitable, and we find the planet has a civilization already, so we land ands claim the land for earth causing a war with alien life? Or do we tuck tail and turn around?

[jamesleatherwood]

While i know our sample size is limited by our tech, and it makes sense that larger objects are the first to be spotted. I play a lot od 4x space sims and one of the defining features of a lot of race creation is homeworld size. At the moment, it seems like we have a small homeworld size... which is normally a pretty limiting factor in alot of areas. lol

[mailasun]

8:20 Kepler-22b is 600 LIGHT YEARS away from ITS STAR??? In the habitable zone??? Gosh! Does anyone do any proof reading? Even if not, does it make sense to you when you read out the script???

[jssomewhere]

The real question is there technology using life besides Earth? Cuz if it's just simple life I think we will find that everywhere. If however it's complex life AKA fish, cats, ect... that is going to be rare. If it's intelligent life, life that develops and uses technology that may exist somewhere besides Earth. Yet it is probably so far away as to make it impossible to reach.
All that said, and if you are a believer in the heat death theory, then the universe may be too young for other intelligent life to have evolved. I know 13.8 billion seems like a very long time and to us it is. Yet the majority of stars in the universe are going to survive 100s of billions or even trillions of years. Looking at things through that lens 13.8 puts the universe still in diapers. So let's talk about it again when the universe gets to 100 billion I bet things are very different at that point. Also remember when all the stars are gone there will be billions or trillions of black holes still rotating meaning life could develop on bodies orbiting them. This universe is just getting started. It has just reached a point that enough elements have formed and stars have spread out. Life, intelligent life will always be rare but us or some other will populate the galaxy at some point. I hope it's us.

[miketaylor]

It's highly unlikely they're as good as the Earth is, or was especially. It's mathematically unlikely even with the unknowns.

[JanLarson]

You might want to consider giving up on the numbers - they are mostly way off. 600 light years from its star? I don't think so.

[GeoPineda]

But... Tess already died on Episode 2...

[Captain.AmericaV]

Life is subjective.

Many think there's nolo carbon based life, but there will be life that are nothing like us.
