This image shows four planetary nebulae from the first systematic survey of such objects in the solar neighborhood made with NASA's Chandra X-ray Observatory. The nebulae are NGC 6543, top left, NGC 7662, top right, NGC 7009, bottom left, and NGC 6826. X-ray emission from Chandra is colored purple, and optical emission from Hubble is colored red, green and blue (X-ray: NASA / CXC / RIT / J. Kastner et al; optical: NASA / STScI)

This Curiosity image shows a rock outcrop called Link. Rounded gravel fragments up to a couple inches in size are in a matrix of white material. Many gravel-sized rocks have eroded out of the outcrop onto the surface, particularly in the left portion of the frame. The outcrop characteristics are consistent with a sedimentary conglomerate, or a rock that was formed by the deposition of water and is composed of many smaller rounded rocks cemented together (NASA / JPL-Caltech / MSSS)
