Interactive Astrophysics Stories

At the MDSGC Observatory, we’re always looking to share our enthusiasm about the Universe and its many fascinating phenomena. Therefore, we’re pleased to continue our new series of interactive online astrophysics stories!

#2: Imaging a Star Cluster

When it comes to practical astronomy, whether we’re idly admiring the night sky or concentrating closely on a telescopic view, star clusters are some of the most interesting things up there. The image above shows a portion of the star cluster Messier 67 obtained from our Observatory. (Another prime example of a star cluster is also one of the Fall sky’s highlights: the Pleiades, or Seven Sisters.) So what, apart from simple visual appeal, makes star clusters interesting for astronomers?

It’s Fall as we write this, and in Earth’s northern hemisphere the days are getting shorter. DayLIGHT, that is! But did you know that actually, the length of Earth’s day is increasing as time goes on? What’s that all about, and what in the Universe could be responsible?
