Second potentially habitable Earth-size planet found orbiting nearby star | CNN

A second Earth-size exoplanet has been spotted orbiting the small star TOI 700, located about 100 light-years away. Astronomers used NASA's planet-hunting TESS mission to spot the fourth world in the planetary system.

can we point the jwst at it?

Presumably...

Small, cool M dwarf stars like TOI 700 are common in the universe, and many have been found to host exoplanets in recent years, like the TRAPPIST-1 system and its seven exoplanets that the James Webb Space Telescope will observe.

I get a little annoyed with these "We found another Earth!" stories.

We keep finding these planets around red dwarfs. These are the most common stars in the universe, but they're also a fraction of the size of the sun, very dim, any very unstable. Since they have a low mass, they have a problem holding their energy in, causing constant violent solar flares. On top of that, the habitable zone around a red dwarf would be closer than the orbit of Mercury. Being that close, the planet will almost certainly be tidally locked (meaning one side will always face the star).

The result will be a planet that's constantly blasted with radiation, an atmosphere that was very likely blown away (unless there's some complx method of replentishing it), one side very hot and one side very cold, and very likely a small sliver of the planet in the "twilight" area that could have any substancial amount of water.

Yes, it's Earth sized. However the chances of life aren't that great.

But you're saying there's a chance...

Sun turnin' 'round with graceful motion
We're setting off with soft explosion
Bound for a star with fiery oceans
It's so very lonely, you're a hundred light years from home

So what was all that one in a million talk????!!!!

Also nevermind the fact that close to a star is probably getting bathed in radiation.

Also, it's just at likely they're all barren due to tidal locking destroying the magnetic dynamo.

When they find a class G or K star with an Earth-size planet between .7 and 1.5 AU from the host, someone buzz my phone.

hopefully 90+ hab/90+ metal

high hability with low resources isnt going to make for a great colony.
(think Dune desert planet)

i knew earth's moon was tidal locked.
didnt know planets could be to the sun.

Any object orbiting a more massive object closely enough will become tidally locked due to shearing forces. The moons of Jupiter are tidally locked to the planet for example.

Earth is a magnificent thing, and humans are beyond miraculous. We should do what's necessary to keep the place inhabitable.

(think Dune desert planet)

I have so far not gotten into Dune. I cut my teeth on Scifi, read lots, my first love in reading but somehow I didn't read Dune or see any movies. I just checked out Dune 2021 from the library in Blu-ray. Saw it highly recommended as true to the spirit and details of Herbert's book, so figure I'll try it. I think I did try the book not long ago but it rubbed me the wrong way with its supernatural considerations. I had a similar reaction to the Harry Potter books and movies, I'm just allergic to supernatural fiction. I bought a few copies of the movies, actually, have yet to watch them.

Mercury is locked and Venus is just about there. A 243 day long day is more of a year.
https://solarsystem.nasa.gov/planets/venus/overview/#:~:text=Venus rotates very slowly on,day longer than its year!

The list of requirements for our meat popcicles is long.

Contrary to some people's viewpoints, this solar system is a pretty special place and so is Earth...especially for its "self-aware" blobs of matter inhabiting it.

Have to agree with you. Never could get into Harry Potter but I did watch all three of the Fantastic Beasts movies which were somewhat enjoyable (because the protagonist is quirky) and the beasts are amusingly fantastic

Dune (2021), everyone says it's the best movie ever but honestly, I thought it was weird. The whole desert and scarce resources (even moisture!) was more depressing than interesting. I don't like movies that make me feel depressed.
