My photo of the moon, Venus and Jupiter last night

This was taken shortly after 9 p.m. with my Canon point &shoot type camera in manual mode.  The moon is over exposed to get Jupiter at the bottom, but does show some earthshine.

03/27/2012 – Ephemeris – Supernova near the direction of Mars

March 27, 2012 Comments off

Ephemeris for Tuesday, March 27th.  The sun will rise at 7:31.  It’ll be up for 12 hours and 32 minutes, setting at 8:04.   The moon, 3 days before first quarter, will set at 1:19 tomorrow morning.

Last week a supernova was spotted in nearby galaxy M95, which happens to be close to the direction where Mars is right now.  It takes a telescope of about 6 inch diameter to spot it.  If you’d like to spot it, Google “M95 supernova” for more information on its exact location.  Since discovery, astronomers have found the progenitor star on an old image of the galaxy taken by the Hubble Space Telescope.  The star that blew itself up appears to have been 8 times the mass of the sun as determined by its color and brightness.  We don’t have to worry about the sun doing the same thing, it’s simply not massive enough.  It’s nice to live orbiting around a boring star of low mass.  Our sun’s wildness is seen in the sunspot cycle.
