    Gone but not forgotten, the Russian Mars 3 lander descended to the surface of the red planet in 1971. This first lander on Mars was meant to take images, but it unexpectedly failed and its transmissions were short-lived. Through the power of citizen scientists, the lander may have been found in images from NASA's Mars Reconnaissance Orbiter. Data from the High Resolution Imaging Science Experiment (HiRISE) appear to have captured objects on the surface of Mars which are consistent with the location, shape and relative positioning of the Mars 3 lander.

    The iconic Horsehead nebula has been the subject of astronomical imagery by amateurs and professionals alike. The region has clouds of ionized hydrogen as well as areas of dark dust that obscure new-forming stars. A new image taken by the Hubble Space Telescope shows new features and hidden stars not seen in the other optical images. A 3D movie of the image gives perspective to the structure of the nebula.
