What this episode covers
We've spotted thousands of planets around other stars in our own Milky Way. But when we look at other galaxies, it's mostly impossible to see individual stars — let alone any planets orbiting them. Recently, astronomers spotted what looks suspiciously like a transit event in the signal from a bright x-ray binary system in the whirlpool galaxy. Could it be an exoplanet? Emily runs throuugh all the ways this might *not* be the case, and we're left with a tantalising "well ... maybe”.
