Meet Gliese 12 b. It's a world, orbiting a distant sun. It's portrayed in this artist's concept as 3 possible worlds, because we don't exactly know its size. But its size is comparable to that of Earth or Venus.Image via @NASAAstrobio on X.

Gliese 12 b is a newly discovered rocky exoplanet, between Earth and Venus in size. It orbits a red dwarf star 40 light-years away...
"Transiting" means this world passes in front of its star from our earthly perspective. That fact makes it possible to observe with TESS, whose full name is the Transiting Exoplanet Survey Satellite...
The uncertainties about Gliese 12 b center on its possible atmopshere. If it doesn't have an atmosphere, computer models indicate its average surface temperature are slightly warmer than Earthlike, with an average temperature of only around 107 degrees Fahrenheit (42 degrees Celsius). That's in contrast to Venus, whose average surface temperature is around 870°F (465°C). The researchers said there are various possibilities regarding its atmosphere and subsequent temperature, though. The possibilities range from no atmosphere for Glise 12 b to a thick Venus-like atmosphere.
Astronomers want to know the details of this exoplanet. That's because worlds like this one might be habitable, perhaps not by earthlings, but possibly by some form of life. And being only 40 light-years away makes it well-suited for follow-up observations with NASA's James Webb Space Telescope.

Start spreading the news. I’m leaving today.
I want to be a part of it, Gliese 12 b.
These vagabond shoes, are longing to stray
Right through the very heart of it, Gliese 12 b.
Any world that I’m welcome to, is better than the one I come from.
I really get tired of this constant search for life elsewhere.
I’m sure there is as I don’t think God put all his eggs in one basket.
Realistically we are all be so far apart we’ll never interact.

Tough.
One word response?
What do you mean?
I worked for a world class observatory for nearly
10 years so I know what most of them are looking for
and subjectively why.
Boo hoo. There’s two words.
