                  Lyrid Meteors from the Constellation Lyra

   Explanation: Where are all of these meteors coming from? In terms of
   direction on the sky, the pointed answer is the [4]constellation of
   Small Harp (Lyra). That is why the famous meteor shower that peaks
   every April is known as the [5]Lyrids -- the [6]meteors all appear to
   came from a [7]radiant toward [8]Lyra. In terms of parent body, though,
   the [9]sand-sized debris that makes up the Lyrid meteors come from
   [10]Comet Thatcher. The comet follows a well-defined orbit around our
   [11]Sun, and the part of the orbit that [12]approaches Earth is
   superposed in front of Lyra. Therefore, when Earth crosses this orbit,
   the [13]radiant point of falling debris appears in Lyra. [14]Featured
   here, a composite image containing over 33 meteors (can you find them
   all?) from last month's [15]Lyrid meteor shower shows several
   [16]bright meteors that [17]streaked over a shore of Sec Lake in the
   [18]Czech Republic. Also visible are the bright stars [19]Vega and
   [20]Altair, the planet [21]Jupiter, and the central band of our
   [22]Milky Way Galaxy.
