Hello everyone!

We are also going to look at the night sky, as Venus, Mars, and the Moon huddle close together. Then, we venture out Enceladus, one of the mighty moons of Saturn, examining its geysers for signs of life. Finally, we journey back to ancient Earth, learning about massive impacts on its young surface.
