Orionids Meteors over Inner Mongolia
Image Credit & Copyright: Yin Hao [3]
Explanation: Meteors have been shooting out from the constellation of Orion.
This was expected, as October is the time of year for the Orionids Meteor
Shower [4] . Pictured here, over two dozen meteors were caught in successively
added exposures last October over Wulan Hada [5] volcano in Inner Mongolia
[6] , China [7] . The featured image shows multiple meteor streaks [8] that
can all be connected to a single small region on the sky called the radiant
[9] , here visible just above and to the left of the belt of Orion [10] , The
Orionids [11] meteors started as sand sized bits expelled from Comet Halley
[12] during one of its trips to the inner Solar System [13] . Comet Halley
[14] is actually responsible [15] for two known meteor showers [16] , the
other known as the Eta Aquarids [17] and visible [18] every May. An Orionids
image featured on APOD [19] one year ago today [20] from the same location
shows the same car. Next month, the Leonids Meteor Shower [21] from Comet
Tempel-Tuttle [22] should also result in some bright meteor streaks.
