July 26, 2024 Researchers explain a new mechanism for ice formation. Ice can form near the free surface of a water droplet via small precursors with a structure resembling ice 0. These are readily formed by negative pressure effects due to surface tension, creating ring-like structures with the same characteristics as ice 0, which act as seeds for nucleation, ...

July 24, 2024 Using the James Webb Space Telescope (JWST), astronomers imaged a new exoplanet that orbits a star in the nearby triple system Epsilon Indi. The planet is a cold super-Jupiter exhibiting a temperature of around 0 degrees Celsius and a wide orbit comparable to that of Neptune around the Sun. This measurement was only possible thanks to JWST's unprecedented imaging capabilities in the thermal ...
