Floating high above the hydrocarbon lakes, wispy clouds have finally started to return to Titan’s northern latitudes.

A satellite is ejected from the Japan Aerospace Exploration Agency (JAXA) Small Satellite Orbital Deployer on the International Space Station on Dec. 19, 2016. The satellite is actually two small satellites that, once at a safe distance from the station, separated from each other, but were still connected by a 100-meter-long Kevlar tether.

This galaxy acts as an astronomical laser, beaming out microwave emission rather than visible light.

Sunlight truly has come to Saturn’s north pole. The whole northern region is bathed in sunlight in this view from late 2016, feeble though the light may be at Saturn’s distant domain in the solar system.

Just hours after the winter solstice, a mass of energetic particles from the Sun smashed into the magnetic field around Earth. The strong solar wind stream stirred up a display of northern lights over northern Canada.

Aboard the International Space Station, Expedition 50 Flight Engineer Peggy Whitson of NASA sent holiday greetings and festive imagery from the cupola on Dec. 18.

This image from NASA’s Cassini spacecraft is one of the highest-resolution views ever taken of Saturn’s moon Pandora. Pandora (84 kilometers, or 52 miles across) orbits Saturn just outside the narrow F ring.

This week in 1968, Apollo 8, the first crewed Apollo mission, launched from NASA’s Kennedy Space Center on Dec. 21, 1968. Here, the S-IC stage is being erected for final assembly of the Saturn V launch vehicle in Kennedy’s Vehicle Assembly Building.

This composite image, made from ten frames, shows the International Space Station, with a crew of six onboard, in silhouette as it transits the sun at roughly five miles per second, Saturday, Dec. 17, 2016, from Newbury Park, California.

Although there are no seasons in space, this cosmic vista invokes thoughts of a frosty winter landscape. It is, in fact, a region called NGC 6357 where radiation from hot, young stars is energizing the cooler gas in the cloud that surrounds them.

Spiral galaxy IC 5201 sits 40 million light-years from us in the Crane constellation. As with most spirals we see, it has a bar of stars slicing through its center.

Hurricane forecasters will soon have a new tool to better understand and forecast storm intensity. A constellation of eight microsatellites, called NASA’s Cyclone Global Navigation Satellite System mission, or CYGNSS, got a boost into Earth orbit aboard an Orbital ATK Pegasus XL rocket, deployed from an L-1011 aircraft.
