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.
