Mars appears light blue in this near-infrared image from Hera’s Hyperscout H hyperspectral imager, acquired during the mission’s March 12 gravity-assist flyby of Mars, with Deimos seen ahead of it. The spacecraft was approximately 1,000 km from the 12.4-km-diameter Deimos when this image was acquired. In the background a variety of Martian features can be observed. At the top of the image is the bright Terra Sabaea region, close to the Martian equator, outlined by darker regions about it, with the 450 km-diameter Huygen crater to the bottom right of Terra Sabaea and the 460-km-diameter Schiaparelli crater to its left. To the bottom right of the Martian disk is Hellas Basin, among the largest known impact craters in the Solar System with a diameter of 2,300 km and a depth of more than 7 km. Image credit: ESA.

Artist’s impression of a hypervelocity star ejected from the Large Magellanic Cloud (shown on right). When a binary star system ventures too close to a supermassive black hole, the intense gravitational forces tear the pair apart. One star is captured into a tight orbit around the black hole, while the other is flung outward at extreme velocities -- often exceeding thousands of kilometers per second -- becoming a hypervelocity star. The inset illustration depicts this process: the original binary’s orbital path is shown as interwoven lines, with one star being captured by the black hole (near center of inset) while the other is ejected into space (lower right).

In the center of the image, the stars cluster to form a bright and dense green candy floss-colored haze, that is the Large Magellanic Cloud. Scattered across the middle of the image are about 50 small yellow crosses, some of them are so close to one another that they almost overlap. SNR J0624-6948 (orange, higher in the image) and SNR J0614-7251 (blue, lower in the image) are seen in the lower left quarter of the image.
