The most CO2 was in an 1,800-kilometre-wide (1,120 mi) region called Tara Regio, where there is a lot of “chaotic terrain” with jagged peaks and cracks. What exactly causes the chaos in the area is not well understood, but one theory is that warm water from the ocean rises up to melt the surface ice, […]
First discovered 400 years ago by astronomer Galileo Galilei, Jupiter’s icy moons were long overlooked as potential candidates to host life. But previous space probes have suggested that beneath their icy shells, there are vast oceans of liquid water – a key ingredient for life as we know it. This has made Ganymede and Europa […]
Io, whose interior is constantly heated by strong gravitational tidal forces, is the most volcanically-active body in our Solar System. The Moon has a tenuous atmosphere composed primarily of sulfur dioxide (SO2), which comes from eruptions of its many volcanoes and sublimation of its SO2 from surface frost. Scientists have used ALMA to study the […]
