Your wish came through.
They manage to mask the light from the parents star, and focus on the light reflected by the planet.
When the light reflects form the surface of the planet, the atmosphere causes it to bend and get polarized.
They are able to detect the light and catch, and developed a system, where it can be identified and even get a spectral analyzing of it.
I recently watched this on a vid. But they said that this new system would be installed into the next large ground telescope.
They never mentioned they could already do the same thing, with the tech already in use.
Forgive me if my explanation isn't completely right... This is what I remember. I'll search for the vid.
Three planetary researchers from SRON and the University of Amsterdam, Theodora Karalidi, Daphne Stam and Joop Hovenier, have calculated that
we can determine whether clouds on an exoplanet contain liquid water by measuring the planet’s polarisation signal. Polarisation describes the
direction in which light waves vibrate. Most stars emit unpolarised light: light waves have no preferred direction of vibration. When starlight is
reflected by a planet, it usually becomes polarised: the reflected light waves vibrate in a preferred direction.
I can't find the vid.
I did find some other interesting stuff on the matter.
I hope that covers it.
