05/01/2015 – Ephemeris – A talk about the Virgo Cluster of galaxies tonight and a star party

May 1, 2015

Ephemeris for Friday, May 1st.  Today the Sun will be up for 14 hours and 14 minutes, setting at 8:47.   The Moon, 2 days before full, will set at 5:55 tomorrow morning.  Tomorrow the Sun will rise at 6:31.

Tonight yours truly will be presenting the program: The Galaxy Cluster Next Door, at this evening’s meeting of the Grand Traverse Astronomical Society at 8 p.m. at Northwestern Michigan College’s Rogers Observatory.  Following at 9 p.m. will be a star party featuring the Moon and planets Venus, Jupiter and later, Saturn.  As to the program:  There is a patch of the spring sky in the constellation of Virgo the virgin, where we are looking out the thin side of our Milky Way galaxy where there is a huge group of over a thousand galaxies astronomers have dubbed the Virgo Cluster.  Galaxy clusters are held together by the gravity of mysterious dark matter, but the clusters are expanding from all the other clusters.

Times are for the Traverse City/Interlochen area of Michigan.  They may be different for your location.
