The first billion years on Earth and Mars: A geologist’s perspective – Clark M. Johnson

Clark M. Johnson

Despite the likelihood of early habitability on both Earth and Mars, the geologic evolution of these two planets, and the rock record they preserve, is quite different. Plate tectonics on Earth played a central role in evolution of our biosphere, and yet has destroyed much of the early Earth rock record, creating great challenges for finding evidence for early life on Earth. Mars did not have Earth-style plate tectonics, but the evidence is clear that Mars was habitable very early in its history. Preservation of the early Mars geologic record is excellent, raising the possibility that it might contain evidence for the earliest life in the Solar System...

Donald Park Star Party

2017 Donald Park Star Party

The Donald Park star party is a family friendly event at a lovely county park. This is a chance to see the stars and planets through many different telescopes and binoculars – bring your blanket or lawn chair and sit back later in the evening for a night of watching meteors.

Presentation for guests on meteor showers and planets by the Madison Astronomical Society before the stars come out. Sunset is about 8:08 pm, observing planets can begin about that time with fainter objects as it gets darker. Temps usually fall a bit after sunset so dress accordingly.
