The next space station grocery run will carry caffeine to a whole new level: Aboard the SpaceX supply ship is an authentic espresso machine straight from Italy.
With its thick, hazy atmosphere and surface rivers, mountains, lakes and dunes, Titan, Saturn's largest moon, is one of the most Earthlike places in the solar system.
A new view of the Moon's formation: Crucial difference in 'fingerprints' confirms explosive, interconnected past
Within the first 150 million years after our solar system formed, a giant body roughly the size of Mars struck and merged with Earth, blasting a huge cloud of rock and debris into space. This cloud would ...
SpaceX is sending its unmanned Dragon cargo ship on its sixth official supply mission to the International Space Station on Monday, should the weather behave itself.
A new analysis of the chemical make-up of meteorites has helped scientists work out when the Earth formed its layers.
Mars has distinct polar ice caps, but Mars also has belts of glaciers at its central latitudes in both the southern and northern hemispheres. A thick layer of dust covers the glaciers, so they appear as surface ...
