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: Orbiting 400 kilometers above Quebec, Canada, planet
   Earth, the International Space Station [5]Expedition 59 crew captured
   this snapshot of the broad St. Lawrence River and curiously circular
   Lake Manicouagan on April 11. Right of center, the ring-shaped lake is
   a [6]modern reservoir within the eroded remnant of an ancient 100
   kilometer diameter impact crater. The ancient crater is very
   [7]conspicuous from orbit, a visible reminder that Earth is vulnerable
   to [8]rocks from space. Over 200 million years old, the Manicouagan
   crater was likely caused by the impact of a rocky body about 5
   kilometers in diameter. Currently, there is no known asteroid with a
   significant probability of impacting Earth in the next century. Each
   month, [9]NASA’s Planetary Defense Coordination Office [10]releases an
   update featuring the most recent figures on near-Earth object close
   approaches, and other facts about comets and asteroids that could pose
   a potential impact hazard with Earth.
