Starting today, stargazers in the Northern Hemisphere can try to catch a glimpse of one of the oldest known meteor showers. The Lyrids meteor shower, which has been viewed by humans annually for nearly 27-hundred years, starts today and lasts until April 29th. In ideal conditions, viewers can spot around 10 to 15 meteors per hour during the shower's peak, which is on April 21st and 22nd. At times, the shower will produce a whopping 100 meteor streaks per hour.
