Pluto as seen from data taken by New Horizon’s flyby in 2015 of the dwarf planet, with a close-up view of the Pigafetta Montes mountain range. The colorization on the right indicates the concentrations of methane ice, with the highest concentrations at higher elevations in red, decreasing downslope to the […]

Cross-section snapshots of 3D simulations of giant impacts using 30 to 100 million particles, coloured by their material or their internal energy, related to their temperature.

Storms gathered at the south pole of Jupiter, as imaged by the Juno probe. Credit: NASA/JPL-Caltech/SwRI/ASI/INAF/JIRAM At the south pole of Jupiter lurks a striking sight—even for a gas giant planet covered in colorful bands that sports a red spot larger than the earth. Down near the south pole of the planet, […]

The four largest moons of Jupiter in order of distance from Jupiter: Io, Europa, Ganymede, and Callisto. Credit: NASA/JPL/DLR The gravitational push and pull by Jupiter’s moons could account for more warming than the gas giant Jupiter alone. Jupiter’s moons are hot. Well, hotter than they should be, for being so […]

A new study published in Science finds that Earth’s water may have come from materials that were present in the inner solar system at the time the planet formed — instead of far-reaching comets or asteroids delivering such water. Enstatite chondrite meteorites, once considered ‘dry,’ contain enough water to fill […]

In this research, the scholars have analysed the conduction of electricity and heat of water under extreme temperature and pressure conditions, such as those that occur inside ice-giant planets as well as in many exo-planets outside of it. Investigating the phenomena that occur under their surface, in fact, is key […]

An artist’s impression of Mars’ inner structure. The topmost layer is the crust, and beneath it is the mantle, which rests on a solid inner core.

On September 18, 2017, ESA astronaut Paolo Nespoli shot this image from the International Space Station showing the Moon rising above the Earth’s horizon together with Mercury, Mars, the star Regulus, and Venus.
