Atmospheres, Escaping

We chase the tenuous atmospheres — exospheres — of active moons and exoplanets, and the physics of how gas escapes across planet–satellite systems. From the volcanic plumes of Io and the sputtered, radiation-worn surfaces of Europa and the Galilean moons, to the sodium and potassium signatures betraying close-in exoplanets, we trace how mass, plasma, and light couple between worlds — escaping atmospheres, tidal and volcanic venting, exomoons, and the fundamental problems that decide where planets and moons stay habitable.

गुरु  ·  the dispeller of darkness

Gurus

In the guru–śiṣya tradition, a guru is the one who turns darkness into light. These are the teachers who did exactly that — whose rigor, imagination, and generosity taught me how to see planets, moons, and the cosmos, and remain woven into everything the Squad does.
