13 Meteor Showers Meteor Showers are events where many meteors can be seen in the sky. Can produce between a few meteors per hour to 1,000 meteors per hour. Perseid Meteor Shower Seen from Snowy Range in Wyoming 2015 © Scott Stein My Banana is a Pink Umbrella

14 Lyrids: Meteor Shower Can be seen between April 16 – 26 each year. Usually peaks around April 22nd. Generates between 5 – 20 meteors per hour So named because they can be seen in the constellation Lyra. 2015 © Scott Stein My Banana is a Pink Umbrella

15 Perseids: Meteor Shower
Can be seen from mid July to late August. Usually peaks around August 9th to 14th. Generates between 80 – 200 meteors per hour So named because they appear to originate in the constellation Perseus. However they can be seen anywhere in the sky. Video: Perseids Meteor Shower 2015 © Scott Stein My Banana is a Pink Umbrella

16 Orionids: Meteor Shower
Can be seen through October 16 – 27 And peak on October 21st. Generates between meteors per hour So named because they appear to originate in the constellation Orion. However they can be seen anywhere in the sky. 2015 © Scott Stein My Banana is a Pink Umbrella

17 Leonids: Meteor Shower
Can be seen from November 15th – 20th. Usually peaks around November 18th. Generates between 80 – 200 meteors per hour So named because they appear to originate in the constellation Leo. However they can be seen anywhere in the sky. 2015 © Scott Stein My Banana is a Pink Umbrella

21 Bolides / Detonating Fireballs
A Bolide is a very bright fireball that explodes in the atmosphere, which is why its also called a detonating fireball. Videos: The Tunguska Event Super-Bolide: 2013 Russian Meteor 2015 © Scott Stein My Banana is a Pink Umbrella

22 Comets A Comet is a rock in space that is very icy and forms a coma and a tail. Some comets originate from the Kuiper belt. 2015 © Scott Stein My Banana is a Pink Umbrella

25 Comets: Coma’s and Tails
A coma is the atmosphere of a comet & the tail is a formation of dust & gas behind it. tail Coma 2015 © Scott Stein My Banana is a Pink Umbrella

26 Comets Tail Formation A tail forms due to the heat of the Sun evaporating frozen gases and releasing dust. The tail always points away from the Sun because the Sun’s cosmic wind pushes it away. 2015 © Scott Stein My Banana is a Pink Umbrella

27 Comet Tail Formation: The tail of a comet can only be seen when it gets close enough to the Sun for it to be heated up. Video: What are Comets? 2015 © Scott Stein My Banana is a Pink Umbrella
