This artist’s illustration shows a giant cloud of hydrogen streaming off the warm Neptune GJ 3470b. The host star’s intense radiation is heating the hydrogen in the planet’s upper atmosphere to a point where it escapes into space. GJ 3470b is losing hydrogen at a rate 100 times faster than a previously observed warm Neptune whose atmosphere is also evaporating away. Image credit: NASA / ESA / D. Player, STScI.

This composite image of Ultima Thule was taken just 33 hours before the December 2 course-correction maneuver that fine-tuned New Horizons’ trajectory for its New Year’s flyby. At left is the full LORRI image with a yellow circle centered on the location of Ultima Thule. Unlike the LORRI images taken in August through October 2018, the object is now evident among the many background stars even without further processing. Nevertheless, Ultima Thule really stands out after subtracting the background stars; the region within the yellow box has been expanded in the star-subtracted version of the image on the right.

This image from InSight’s robotic-arm mounted Instrument Deployment Camera shows the instruments on the spacecraft’s deck, with the Martian surface of Elysium Planitia in the background. The color-calibrated picture was acquired on December 4, 2018 (Sol 8); in the foreground, a copper-colored hexagonal cover protects the SEIS seismometer; the gray dome behind SEIS is the wind and thermal shield, which will be placed over SEIS; to the left is a black cylindrical instrument, the Heat Flow and Physical Properties Probe (HP3); HP3 will drill up to 16 feet (5 m) below the Martian surface, measuring heat released from the interior of the planet; above the deck is InSight’s robotic arm, with the stowed grapple directly facing the camera; to the right can be seen a small portion of one of the two solar panels that help power InSight and part of the UHF communication antenna.

InSight flipped open the lens cover on its Instrument Context Camera (ICC) on November 30, 2018, and captured this view of Mars. Located below the deck of the InSight lander, the ICC has a fisheye view, creating a curved horizon. Some clumps of dust are still visible on the camera’s lens. One of the spacecraft’s footpads can be seen in the lower right corner. The seismometer’s tether box is in the upper left corner. Image credit: NASA / JPL-Caltech.

This map of the entire sky shows the location of 739 blazars used in NASA’s Fermi Gamma-ray Space Telescope’s measurement of the extragalactic background light. The background shows the sky as it appears in gamma rays with energies above 10 billion electron volts, constructed from nine years of observations by Fermi’s Large Area Telescope. The plane of our Milky Way Galaxy runs along the middle of the plot. Image credit: NASA / DOE / Fermi LAT Collaboration.
