Bob Moler's Ephemeris Blog

Ephemeris for Monday, May 20th.  Today the sun will be up for 15 hours and 0 minutes, setting at 9:09.   The moon, 2 days past first quarter, will set at 3:45 tomorrow morning.  Tomorrow the sun will rise at 6:08.  |  I found this item at Universe Today, an astronomical news website, universetoday.com.  The Hubble Space telescope has found evidence of rings of mainly silicon around two white dwarf stars in the Hyades star cluster.  The Hyades is the V-shaped star cluster just below the setting Jupiter these nights.  White dwarf stars are old stars in their last stage of life and usually don’t show the absorption of heavy elements in their spectrum.  These two stars must have pulverized rings of silicon plus a little carbon orbiting them, suggesting the formation of earth-like planets.  Astronomers usually don’t see this in cluster stars, which are generally young and too active to show planet forming material close to them.

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