09/09/2014 – Ephemeris – Our address in the universe just changed

September 9, 2014

Ephemeris for Tuesday, September 9th.  The sun will rise at 7:14.  It’ll be up for 12 hours and 49 minutes, setting at 8:04.   The moon, 1 day past full, will rise at 8:19 this evening.

Two and a half years ago my wife and I took a week-long cruise around the Hawaiian Islands.  I always said I’d go back in a minute.  Well, now maybe I and you are already there… in spirit, anyway.  Astronomers at the National Radio Astronomy Observatory and the University of Hawai’i announced the pinning down the dimensions of the local supercluster of galaxies containing over 100 quadrillion stars spread over a diameter of more than 500 million light years that they have dubbed Laniakea which in Hawaiian means “immense heaven”.  The lead researcher was R. Brent Tully of the University of Hawai’i. Also participating were two astronomers from France and one from Hebrew University.  So your ultimate address is: your address, City, State, Country, Earth, Solar System, Orion spiral arm, Milky Way Galaxy, Local Group, Laniakea supercluster, Universe, and maybe Multiverse.
Times are for the Traverse City/Interlochen area of Michigan.  They may be different for your location.

Addendum
