Mercury will reach its greatest eastern elongation on Oct. 29, marking one of the best evenings to see the planet this fall as it appears farthest from the sun’s glare in the twilight sky.
As the solar system’s innermost planet, Mercury travels an extremely tight orbit around our parent star, with an average separation of under 36 million miles (58 million kilometers). As a result, it…
Earth’s moon is a treasure trove of resources. Space agencies around the world are planning missions to access and use lunar volatiles, which include hydrogen, water, helium, carbon dioxide, and carbon monoxide, in order to produce fuel sources, breathable air, and…
An innovative technique for measuring the force acting on individual grains of sand could help scientists uncover how winds have shaped the surface of Mars.
