Day 90: Stellar Life Cycle – Day 1 January 17, 2007

Posted by Admin in Astronomy, Science in the News.

The big questions of today:  How are stars born?  How do they evolve over time?  We focused on the first half of the stellar life cycle today by taking some PowerPoint notes over the topic.  These slides included information on the star nursery (nebula), the middle life of the star (main sequence), and the older years of the star (the Red Giant phase).  Tomorrow we will focus on the second half of the life cycle:  How stars die.

Although Comet McNaught is gone from the nighttime sky here in the Northern Hemisphere, it is still getting lots of attention.  Check out the article in the Tonganoxie Mirror all about how we’ve discussed Comet McNaught in our own class.  As comet McNaught brightens for Southern Hemisphere viewers, we are certain to get even more brilliant images over the coming weeks.  It is now reportedly even brighter than Venus!  Be sure to check out SpaceWeather for daily updates and new photographs.
