In 1669, French-Italian astronomer Giovanni Cassini arrived at the still-under-construction Paris Observatory as its new director. He quickly talked Louis XIV's minister of finance into buying a ...

Excess heat is flowing from the north pole of Enceladus, hinting at a careful energy balance deep that may have kept the subsurface ocean stable over geologically significant timescales, boosting its ...

Saturn's Enceladus moon might be capable of supporting life, according to data collected by NASA's Cassini mission and compiled in a new study.

Cassini’s new analysis shows Saturn’s moon Enceladus leaking heat from both poles, not just the south. This balanced heat flow suggests its underground ocean could stay liquid for geological ages, ...

The frigid conditions on the surface of Saturn's largest moon, Titan, allow simple molecules in its atmosphere to break one of the most fundamental rules in chemistry, a new study shows. According to ...

Emily Kwong and Regina Barber of NPR's Short Wave discuss new findings about the ocean of Saturn's moon Enceladus, the secrets behind chameleons' eye movements and the energy use behind AI computing.

A laser-based ice drill can bore deep, narrow channels into ice while keeping both mass and energy requirements lower than traditional tools. A new laser concept could revolutionize how we explore the ...

A Supermoon, also known as the Beaver Moon, is expected to peak Wednesday morning. People interested in the giant moon should enjoy looking up at the sky Tuesday night. However, it won’t reach peak ...
