#SourceToSink movement of #dust in the #CriticalZone is what we study every day. This recent paper from Tomonori Totani describes the research possibility in source to sink transport of dust through space.

"Grains ejected by asteroid impacts from exoplanets in the Milky Way and then travelling to the Solar System" could provide evidence of #extrasolar life.

We're always fascinated by the many ways dust influences the human experience.

59 New Planets Discovered in Our Neighborhood
https://www.universetoday.com/160257/59-new-planets-discovered-in-our-neighborhood/
The hunt for #habitable #extrasolar #planets continues! Thanks to dedicated missions like Kepler, TESS, and Hubble, the number of confirmed extrasolar planets has exploded in the past fifteen years (with 5,272 confirmed and counting!).

Sadly I won’t be there in person to see for myself. I would love to see a new habitable world for the first time.

“NASA’s James Webb telescope discovers its first Earth-sized exoplanet / LHS 475 b is a rocky exoplanet roughly the same size as Earth that orbits very close to a small, dim star. And for the first time, researchers are able to study the planet’s atmosphere.”

Terrestrial #extrasolar #planets around low-mass stars are prime targets when searching for atmospheric #biosignatures with current and near-future telescopes.

The #habitable-zone Super-Earth LHS 1140 b could hold a hydrogen-dominated atmosphere and is an excellent candidate for detecting atmospheric features.

The planet could be one of the best known targets to detect biosignature gases with #JWST or #ELT. https://astrobiology.com/2020/12/detectability-of-biosignatures-on-lhs-1140-b.html
