Eta Aquarids fireball and twin meteors over Half Dome, California
The Eta Aquarids are one of two annual showers caused by Halley's Comet. (The other one is the Orionids, in October.) They are named after their apparent "radiant" point in the constellation Aquarius, near one of its brightest stars, Eta Aquarii. Astrophotographer David Hoffman captured this cool photo of an Eta Aquarid fireball and twin meteors over Half Dome, California at Yosemite National Park in May 2014.
The comet whose trail of crumbs causes the annual Eta Aquarid meteor shower is Halley's Comet. In 1986, the two Soviet Union's two Vega spacecraft flew by the comet and snapped about 1,500 images of the icy space rock. The closest approach of Vega 1 to Halley was 5,524 miles (8,890 kilometers) while Vega 2 had a close encounter at 4,990 miles (8,030 km).
Edmond Halley (1656 - 1742) was the English scientist and astronomer who gave his name to the famous comet after accurately predicting its arrival around the year 1740. [Edmond Halley Biography: Facts, Discoveries and Quotes]
Fireball at Devil's Tower

Meteors over Wales
Astrophotographer Kris Williams captured this photo of an Eta Aquarid meteor from Snowdonia National Park in Wales on May 6, 2013. "Atop a peak and overlooking the classic Snowdon Horseshoe view in the distance, with the company of an old hawthorn just starting to bud for Spring, and one of the many Eta Aquarid meteors that shot overhead tonight as part of their annual storm," Williams wrote on his Flickr page.
Eta Aquarids and the Moon
"To the right of the moon ... the tail is green and the leading part reddish," astrophotographer Mike Lewinski wrote when he shared this photo of an Eta Aquarid meteor on Flickr in 2013. "I debated what lens to use when shooting this shower, as experience was telling me the tails would be short. I went with the 18mm over 16mm, but am thinking now that I could have gone with the 55mm and captured this one much better," he said.
