Radar data of comet P/2016 BA14 taken over three days (March 21-23, 2016), when the comet was between 2.5 million miles and 2.2 million miles (4.1 million kilometers and 3.6 million kilometers) from Earth.

NASA's Dawn spacecraft has revealed marvelous sights on dwarf planet Ceres during its first year in orbit.

NASA's Mars Reconnaissance Orbiter has clocked more than a decade of service at the Red Planet and has yielded scientific discoveries and magnificent views of a distant world. These images taken by MRO's HiRISE camera are not in true color because they include infrared information in order to be optimized for geological science.

Jupiter, its moons and moon shadows.

Five morning planets, comet Catalina passes Polaris, and icy Uranus and icy Vesta meet near Valentine's Day.

What's Up for January? A meteor shower, a binocular comet, and the winter circle of stars!

Curiosity performs the first investigation of active sand dunes on another planet. Studying the Bagnold Dunes on Mars will help scientists understand the physics of Martian dunes and how they move.

Dwarf planet Ceres is shown in these false-color renderings, which highlight differences in surface materials. Images from NASA's Dawn spacecraft were used to create a movie of Ceres rotating, followed by a flyover view of Occator Crater, home of Ceres' brightest area.

Honey, I shrunk the satellites! Mini-satellites are following in the footsteps of cell phones and computers. CubeSats are small but highly capable of performing a variety of space missions.
