Description: Svaka zvijezda koju vidimo na nebu ima barem jedan planet koji orbitira oko nje, kaže astronomkinja Sara Seager. Što znamo o ovim egzoplanetima i kako možemo saznati više? Seager nas upoznaje sa svojim najdražim nizom egzoplaneta i pokazuje novu tehnologiju koja će pomoći u skupljanju podataka o njima - čak i pomoći u potrazi za egzoplanetima koji imaju život.

Here I say, "And under that wouldn't be rock, but a form of high-pressure ice, like ice IX." 

I used ice IX to refer to the general category of high-pressure ices because it's a familiar term from Kurt Vonnegut's *Cat's Cradle*, but if GJ 1214b, the planet I'm discussing here, is in fact a water world, its most likely form is ice VII (and possibly ice X) due to the planet's predicted interior temperatures. See the upper left of this [water phase diagram](http://ergodic.ugr.es/termo/lecciones/water1.html).

Potraga za planetima izvan Sunčevog sustava

Recent discoveries reveal that every star in the night sky hosts at least one planet, and the Milky Way alone teems with billions. Astronomers are now on the brink of identifying planets with conditions similar to Earth. Using innovative tools like the starshade, researchers are developing ways to study distant atmospheres for signs of life. This search may soon answer humanity’s oldest question: are we alone in the universe.
