I am pleased to announce the upcoming Continuing Education (non-credit) astronomy events
and classes at College of DuPage for the Spring 2014 term. We have had tremendous support
in the last few terms and I look forward to seeing you all again. Feel free to share this information
with anyone interested in attending.
The schedule for Spring 2014 is as follows:
Free public lecture: Alien Worlds: Exploring Extrasolar Planets
Saturday, Feb 15, 7:00 --- 9:00 pm, HSC 1234
In recent years astronomers have not only found planets orbiting other stars, they have begun
exploring these strange, exotic worlds. They have determined their sizes, masses, diameters,
temperatures and other properties. How have they done this? What have we learned about other
planetary systems? And what do these discoveries tell us about our own solar system? Join us in
exploring these truly alien worlds.
Classes: Hot Topics in Astronomy --- Fridays 7:00 --- 9:00 pm
Hubble Space Telescope --- Feb 28
Since its launch in 1990, the Hubble Space Telescope has become an icon of astronomical discovery.
Its images have redefined nearly every area of astronomy. How does this orbiting observatory work?
What have been some of its historic discoveries? And what legacy will it leave us when its mission is completed
Mars --- Mar 7
In the past two decades, NASA has sent a flurry of spacecraft to explore Mars from orbit and from its surface.
What have these missions found? We will review the major discoveries of the Mars Odyssey, Spirit and
Opportunity, Mars Reconnaissance Orbiter, and Phoenix missions. An update on the current status of the
Curiosity rover now on Mars will also be included.
Holes --- Mar 21
Black Holes have been the ultimate astronomical mystery since their discovery. What are these strange objects?
Where do they come from? How do they form? And how can we study something that is invisible? Our
investigation will answer these and other questions about black holes.
Invisible Universe --- Mar 28
In the 1970s, astronomers found evidence that the majority of the universe was invisible but could only be
indirectly detected. What is this “dark matter” and what are the implications of its discovery for the structure
of the universe? Then, in the late 1990s, two teams of astronomers independently discovered evidence that a
mysterious force was accelerating the expansion of the universe! What is this "dark energy" and what are the
implications of its discovery for the future of the universe? Join us in exploring the unseen universe.
You are now able to sign up for
individual classes (although we hope you can make all of them)
and the price per class will be reduced from that shown in the paper catalog. I look forward to
seeing you all soon!

Want to Discover a Comet?
ESA/NASA's Solar and Heliospheric Observatory (SOHO)'s realtime coronagraph movies are online. Anyone can access the data. Half of the top ten SOHO comet hunters are amateurs. Oates: 28 discoveries; Stezelberger: 14 discoveries; Boschat: 11 discoveries; Lovejoy: 9 discoveries; and Meyer: 7 discoveries.
