Ahsoka is a jack of all trades. The former Jedi has served as TheClone Wars’ protagonist, Rebels’ helpful ally, The Mandalorian’s spiritual guide, and The Book of Boba Fett’s “friend of the family.” Now, she’s starring in her own self-titled series, and it’s unclear just what form a live-action protagonist Ahsoka will take. We know that she’ll be looking for her old friend Ezra Bridger and that Thrawn will make an appearance, but not much else.

But a new theory suggests Ahsoka’s story will be much bigger than just this search. In fact, it could shape the future of the Jedi Order forever.

If scientists want to find aliens on Mars, they may need to start by looking at microscopic fossils in lava rocks here on Earth.

According to a recent study published in the journal Astrobiology, microscopic Triassic fossils hidden in cracks in seafloor basalt could show astrobiologists how to look for remains of long-ago life beneath the surface of Mars or even the icy moons of Saturn and Jupiter.
