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.

View Mars this month, and get a preview of great Mars views in 2016, the best since 2005!

As we honor the retirement of Director Charles Elachi, we look back at the JPL achievements of the past 15 years.

Earth's land and ocean currently absorb about half of all carbon dioxide emissions from the burning of fossil fuels, but it's uncertain whether the planet can keep this up in the future. NASA's Earth science program works to improve our understanding of how carbon absorption and emission processes work in nature and how they could change in a warming world with increasing levels of emissions from human activities.

See all the phases of the moon, by day and by night! Find out why the same side of the moon always faces the Earth, and look for the areas where all six of the Apollo missions landed.

JPL scientist Marina Brozovic explains how radar will be used to study asteroid 2015 TB145 when it safely passes Earth on Oct. 31, 2015.

On Oct. 28, 2015, NASA's Cassini spacecraft will take the deepest dive ever through the plume of Saturn's moon Enceladus. Scientists hope this close flyby will shed light on what's happening beneath the moon's icy surface.
