Almost all of the information and pictures scientists have today from the outer planets is due to flyby missions such as NASA’s Voyager 2. As we learned in the last unit, flyby space probes are especially helpful because they can pass by and gather information on multiple planets within one single mission, and that is… Continue reading Voyager 2 Continue reading → Continue reading
An interesting characteristic that all the jovian planets possess is their rings. The most remarkable and noticeable of these are Saturn’s, which extend hundreds of thousands of kilometers wide. However, Jupiter, Uranus, and Neptune all have rings as well, on a much smaller scale. Although the rings are rather wide, they are only 1-1000 m… Continue reading Put a Ring on It Continue reading → Continue reading

Johannes Kepler (December 27, 1571-November 15, 1630) Johannes Kepler contributed significantly to the world of astronomy by finally proving that planetary orbits were not perfect circles, but ellipses. Up until his time, all astronomers insisted that the planets orbits be perfect circles because everything in the universe was created by God, and God was perfect.… Continue reading Johannes Kepler in Context Continue reading → Continue reading
In the spirit of being in an astronomy class, I felt inclined to download a stargazing app onto my phone. StarMap3D+ was recommended by a multitude of people to me, so I downloaded it.
