12/29/2016 – Ephemeris – Astronomical milestones of 2016

December 29, 2016

Ephemeris for Thursday, December 29th.  The Sun will rise at 8:19.  It’ll be up for 8 hours and 50 minutes, setting at 5:10.  The Moon is new today, and won’t be visible.

Looking back at 2016 the biggest astronomical news was the detection of gravitational waves coming from two separate collisions of black holes far beyond our Milky Way galaxy.  The two detectors in Washington state and in Louisiana recorded these events in September and December 2015, but the first announcement was made in February this year after the signals were cleaned up and studied.  The year saw the end of the European Space Agency’s Rosetta Mission to the comet we’ve come to call 67P after orbiting it for over two years.  The Opportunity and Curiosity rovers continued their exploration of Mars along with a fleet of satellites.  On a sad note, we lost pioneering Mercury astronaut John Glenn at the age of 95.

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