Born in 1473, he was the creator of the modern solar system model which illustrated the retrograde motion of the outer planets. Considering this was well over 530 years ago, and in a rather “unenlightened” time, his revolutionary thinking about what we now consider natural is astounding.

With a bit of time to spare before the Moon rises tonight, let’s begin our journey further south into Lepus as we take a look at Alpha. Its name is Arneb and it is a quality double star that resides around 900 light-years distant. Arneb’s 11th magnitude disparate companion will take a larger scope to resolve. Its wide separation of 35.5″ means it is probably not a true physical companion, but it is a challenge worthy of your time.

What’s Up this Week: January 22 – January 28, 2007

McNeilMonday, January 22 – Be out early tonight to catch the slender crescent Moon as we begin our journey designed to acquaint you with specific craters. Around midway on the terminator, you will spot a conspicuous old crater called Langrenus. Named for Belgian engineer and mathematician Michel Florent van Langren, this handsome old crater stretches out over 132 kilometers in diameter. Look closely at its walls, they rise above the surface by 1981 meters and the deepest part of the floor drops down below 4937 meters – deeper than Mount Cotacachi in Ecuador is tall. Is the Sun rising over its brilliant east wall? If so, look closely and see if you can spot Langrenus’ central mountain peak rising up 1950 meters. Then get out your skis, because that’s as high as the base elevation in Jackson Hole, Wyoming!

Monday, January 8 – On this day in 1942 – precisely 300 years after the death of Galileo, Stephen Hawking was born. The British theoretical astrophysicist, despite his physical limitations, became one of the world’s foremost leaders in cosmological theory and his book “A Brief History of Time” remains one of the best written on the subject.Also born on this day in 1587 was Johannes Fabricius, son of the discoverer of variable star Mira, David Fabricius. Like many father and son teams, the pair went on to study astronomy together, and some of their most frightening work dealt with viewing sunspots through an unfiltered telescope – a practice which eventually blinded Galileo!
