Sierra Nevada Meteor: Loud Explosion And Fireball Likely Caused By Meteor, Astronomers Say

By MARTIN GRIFFITH 04/22/12 07:19 PM ET AP

RENO, Nev. -- Astronomers say a loud explosion heard across a large swath of Nevada and California on Sunday morning was likely caused by a meteor.

The sound of the explosion around 8 a.m. prompted a flood of calls to law enforcement agencies on both sides of the Sierra Nevada in the two states.

The explosion rattled windows and shook houses from Reno to Winnemucca in Nevada, and from the Sacramento to Bakersfield areas in California.

Some people in the two states reported seeing a fireball streak across the sky at the same time.

Dan Ruby of the Fleischmann Planetarium at the University of Nevada, Reno, says the reports indicate the meteor broke up above Earth somewhere over the Sierra southwest of Reno.

There were no reports of earthquakes at the time.

  • A meteor (L) from the Geminids meteor shower enters the Earth's atmosphere past the stars Castor and Pollux (two bright stars, R) on December 12, 2009 above Southold, New York. This meteor shower gets the name 'Geminids' because it appears to radiate from the constellation Gemini. Geminids are pieces of debris from an asteroid called 3200 Phaethon. Earth runs into a stream of debris from the object every year in mid-December, causing the meteors. The peak of the shower is expected the night of December 13-14 at about 0500 GMT on December 14.

In mid-December 2010, the Geminid meteor shower will make its annual appearance, just in time for Christmas. Astronomers consider it the best meteor shower of 2010, with more than 100 meteors streaking through the night sky every hour.
