The Solar System consists of the Sun and its planetary system of eight planets, their moons, and other non-stellar objects. It formed 4.6 billion years ago from the gravitational collapse of a giant molecular cloud. The vast majority of the system's mass is in the Sun, with most of the remaining mass contained in Jupiter.

Black Holes exist, but they are absolutely not what they are proclaimed to be, and they do not deserve such a flamboyant name. A Black Hole is neither black nor does it have a hole to fall into. It is not a tunnel or wormhole to another universe. It is not a monster that spaghettify you. It is an eventless position, zero volume. No event-horizon th...

Plain Language Summary
To study impact craters on solid bodies across the solar system, we need to be able to see and measure them. Our ability to see and measure craters is affected by how we take images of them. If the sun is too high in the sky, or too low on the horizon, it can mask our ability to see craters and other geologic features. If the...
