Astronomy Picture of the Day

   [1]Discover the cosmos! Each day a different image or photograph of our
      fascinating universe is featured, along with a brief explanation
                    written by a professional astronomer.

   Explanation: Sharp telescopic views of [7]NGC 3628 show a puffy
   galactic disk divided by dark dust lanes. Of course, [8]this deep
   portrait of the magnificent, edge-on spiral galaxy puts some
   astronomers [9]in mind of its popular moniker, the Hamburger Galaxy. It
   also reveals a small galaxy nearby, likely a satellite of NGC 3628, and
   a faint but extensive [10]tidal tail. The drawn out tail stretches for
   about 300,000 light-years, even beyond the right edge of the wide
   frame. NGC 3628 shares its neighborhood in the local universe with two
   other large spirals [11]M65 and [12]M66 in a grouping otherwise known
   as [13]the Leo Triplet. Gravitational interactions with its [14]cosmic
   neighbors are likely responsible for creating the tidal tail, as well
   as the extended flare and warp of this spiral's disk. [15]The
   tantalizing island universe itself is about 100,000 light-years across
   and 35 million light-years away in the northern springtime
   constellation Leo.
