Surviving in Ocean Worlds: Experimental Characterization of Fiber Optic Tethers across Europa-like Ice Faults
As an initial step towards in-situ exploration of the interiors of Ocean Worlds to search for life using cryobot architectures, we test how various communication tethers behave under potential Europa-like […]

Land Fraction Diversity On Earth-like Planets And Implications For Their Habitability
A balanced ratio of ocean to land is believed to be essential for an Earth-like biosphere and one may conjecture that plate-tectonics planets should be similar in geological properties.

Mars Was Covered By 300 Meter Deep Oceans
Mars is called the red planet. But once, it was actually blue and covered in water, bringing us closer to finding out if Mars had ever harboured life.

TOI-1695 b: A Keystone Water World Elucidating Radius Valley Emergence Mechanisms Around Early M Dwarfs
Characterizing the bulk compositions of transiting exoplanets within the M dwarf radius valley (i.e. keystone planets) offers a unique means to establish whether the radius valley emerges from an atmospheric […]
