Using the ULTRACAM instrument on the 4.2-m William Herschel Telescope, a group of astronomers led by Jakub Bochinski of Open University in Milton Keynes, UK, has observed a massive, comet-like tail of dust coming from the low-mass terrestrial exoplanet KIC 12557548b.

The Hubble image on the left (unlabeled at top left, labeled at bottom left) shows the beginning of the event, which took place on January 24, 2015. From left to right the moons Callisto and Io are above Jupiter's cloud tops. The shadows from Europa (not seen in the image), Callisto, and Io are strung out from left to right. Near the end of the event, approximately 42 minutes later (right-side image), Europa has entered the frame at lower left. Slower-moving Callisto is above and to the right of Europa. Fastest-moving Io is approaching the eastern limb of the planet; its shadow is no longer visible on Jupiter. Europa's shadow is toward the left side of the image, and Callisto's shadow to the right. Missing from the sequence is the moon Ganymede, which was outside Hubble's field of view and too far from Jupiter in angular separation to be considered part of the conjunction. The moons in these photos have distinctive colors. The ancient, cratered surface of Callisto is brownish; the smooth icy surface of Europa is yellow-white; and the volcanic, sulfur-dioxide surface of Io is orange. The apparent fuzziness of some of the shadows depends on the moons' distances from Jupiter. The farther away a moon is from the planet, the softer the shadow, because the shadow is more spread out across the disk. The images were taken with Hubble's Wide Field Camera 3 in visible light.

This image shows the famous Trifid Nebula to the right of center; it appears as faint and ghostly at these infrared wavelengths when compared to the familiar view at visible wavelengths; this transparency has brought its own benefits - many previously hidden background objects can now be seen clearly; among these are two newly discovered Cepheid variable stars, the first ever spotted on the far side of our Milky Way Galaxy near its central plane.
