Universe Today – Methane-Filled Lakes on Titan are “Surprisingly Deep”.
During Cassini’s final flyby of Titan, it aimed its radar at some of the moon’s liquid lakes. The data shows that those lakes are up to 100 meters (300 ft) deep. The data from those final days also sheds new light on Titan’s hydrocarbon cycle. Hydrocarbon rains feed the lakes, which then are subject to evaporation. Some of the liquid seeps into the subsurface, which would leave reservoirs of liquid hydrocarbons below the surface.
Universe Today – TESS Just Found its First Earth-Sized World.
NASA’s new exoplanet-hunting telescope, TESS (Transiting Exoplanet Survey Satellite), just found its first Earth-sized world. Mission planners expect TESS should find about 300 Earth-sized or Super-Earth-sized exoplanets in its two-year mission. The mission was designed to find the smaller Earth-size ones. The Kepler space telescope found more planets but they were larger planets.
