Callisto from JWST: CO2-rich terrain on the leading hemisphere and global patterns of H2O ice
Maria Camarca, Katherine de Kleer, Richard J. Cartwright +5
We present maps of H2O, CO2, and a 4.57 um spectral feature across Callisto's surface observed using the James Webb Space Telescope (JWST). H2O ice was mapped by measuring band par…

Experimental demonstration of electric power generation from Earth's rotation through its own magnetic field
Christopher F. Chyba, Kevin P. Hand, Thomas H. Chyba
Earth rotates through the axisymmetric part of its own magnetic field, but a simple proof shows that it is impossible to use this to generate electricity in a conductor rotating wi…
