This exciting image, taken at a highly oblique angle, shows the interior of Tyagaraja crater (with north being to the right). Complete with central peaks, extensive hollows, and sloping terraced walls, this view allows us to get a unique perspective into the crater and complements other images by adding a different look at the topography of the surface.

This oblique view highlights, from top to bottom, Balzac, Phidias, Tyagaraja, Stevenson, and Zeami craters. While named craters are still sparse across much of Mercury, this region was observed by Mariner 10, allowing for plenty of time to propose names. In Mariner 10 images of Mercury, craters like Tyagaraja and Zeami were described as hosting bright floor deposits, but the relatively low resolution at which they were imaged did not allow for a more detailed analysis. We now know that craters such as these host hollows (see the links above for higher resolution images of each crater in this scene).
