Re: Terry's Astronomy Thread.
What's in the sky tonight?
November 24, 2012
-Look left of the Moon this evening, by a fist-width at arm's length or a little more, for the two or three brightest stars of Aries.
-Mercury emerges into dawn view around November 24th or so, brightening from magnitude +1 to 0 this week. Look for it just above the east-southeast horizon in early dawn, far to the lower left of Venus and Saturn as shown here. Mercury is beginning its best apparition of the year for viewers at mid-northern latitudes.
Astro Picture of the Day:

Barred spiral galaxy NGC 1365 is truly a majestic island universe some 200,000 light-years across. Located a mere 60 million light-years away toward the chemical constellation Fornax, NGC 1365 is a dominant member of the well-studied Fornax galaxy cluster. This sharp color image shows intense star forming regions at the ends of the bar and along the spiral arms, and details of dust lanes cutting across the galaxy's bright core. At the core lies a supermassive black hole. Astronomers think NGC 1365's prominent bar plays a crucial role in the galaxy's evolution, drawing gas and dust into a star-forming maelstrom and ultimately feeding material into the central black hole. Discovered on October 27, the position of a bright supernova is indicated in NGC 1365. Cataloged as SN2012fr, the type Ia supernova is the explosion of a white dwarf star.
