As you may have noticed, there’s a new super-high resolution mosaic of the planet Mercury that’s available.
How high resolution is it? Perhaps you should join me on my journey as I zoom in to the upper left hand corner. (Click each image to view it full-size.)
While Mercury may look unevenly cratered, keep in mind that there’s a trick of the light going on here. When you’re close to the limit of where the Sun’s rays reach (the terminator), angles are lower and shadows are longer, making craters appear more pronounced.
In reality, there are “young” regions all over Mercury, where more recent lava activity has covered up old craters. In regions that are young, only a few, relatively recent craters cover the surface.
But I’ve chosen an “old” area to zoom in on. An area with craters atop craters atop craters. And I find it absolutely spectacular.
