Description: Svaka zvezda koju vidimo na nebu ima bar jednu planetu koja kruži oko nje, kaže astronom Sara Siger. Šta znamo o ovim egzoplanetama i kako možemo saznati više? Sigerova predstavlja svoj omiljeni skup egzoplaneta i pokazuje novu tehnologiju koja može pomoći da se dobiju informacije o njima - pa čak i da nam pomognu u potrazi za egzoplanetama sa životom.

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 planetama van našeg Sunčevog sistema

Svaka zvezda koju vidimo na nebu ima bar jednu planetu koja kruži oko nje, kaže astronom Sara Siger. Šta znamo o ovim egzoplanetama i kako možemo saznati više?

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.
