This illustration shows several comets speeding across a vast protoplanetary disk of gas and dust and heading straight for the youthful, central star HD 172555. These exocomets will eventually plunge into the star and vaporize. HD 172555 represents the third extrasolar system where astronomers have detected doomed, wayward comets. All of the systems are young, under 40 million years old. Image credit: NASA / ESA / A. Feild & G. Bacon, STScI.

Color composite of Phobos taken with TGO’s CaSSIS camera on November 26, 2016. The observation was made at a distance of 4,785 miles (7,700 km). To create the final color image, two images were taken through each of the four color filters of the camera -- panchromatic, blue-green, red and infrared -- and then stitched together and combined to produce the high-resolution composite. Two of the color filters used by CaSSIS lie outside the wavelength response of the human eye, so this is not a ‘true’ color image. However, showing the data as a color representation can reveal details of the surface mineralogy. Different colors are clearly seen, with the bluest part in the direction of the large crater Stickney, which is out of view over the limb to the left. Although the exact composition of the material is unknown, the color differences are thought to be caused by compositional variations on scales of hundreds of feet to several miles.

This map of dark matter was obtained from data from the KiDS survey, using ESO’s VLT Survey Telescope. It reveals an expansive web of dense (light) and empty (dark) regions. This image is one out of five patches of the sky observed by KiDS. The invisible dark matter is seen rendered in pink, covering an area of sky around 420 times the size of the full Moon. This image reconstruction was made by analyzing the light collected from over 3 million galaxies more than 6 billion light-years away. The observed galaxy images were warped by the gravitational pull of dark matter as the light traveled through the Universe. Some small dark regions, with sharp boundaries, appear in this image. They are the locations of bright stars and other nearby objects that get in the way of the observations of more distant galaxies and are hence masked out in the map as no weak-lensing signal can be measured in these areas.
