Title:
Leonids from Leo
Explanation:
Is Leo leaking? Leo [
http://www.astro.wi
], the famous sky constellation [
http://www.astro.wi
] visible on the left of the above all-sky photograph [
http://www.uniba.sk
], appears to be the source of all the meteors [
http://www.corvus.c
] seen in 1998's Leonids Meteor Shower [
http://leonid.arc.n
]. That Leonids [
http://antwrp.gsfc.
] point back to Leo is not a surprise - it is the reason that this November meteor shower [
http://antwrp.gsfc.
] is called the Leonids. Sand-sized debris [
http://antwrp.gsfc.
] expelled from Comet Tempel-Tuttle [
http://antwrp.gsfc.
] follows a well-defined orbit about our Sun, and the part of the orbit that approaches Earth [
http://antwrp.gsfc.
] is superposed in front of the constellation Leo. Therefore, when Earth crosses this orbit, the radiant [
http://liftoff.msfc
] point of falling debris [
http://www.aero.org
] appears in Leo. Over 150 meteors [
http://www.nineplan
] can be seen in the above [
http://www.uniba.sk
] four-hour effort. The Leonids Meteor Shower of 2003 [
http://comets.amsme
] is expected to have two peaks, the first three days ago and the second [
http://science.nasa
] a long-duration peak covering much of November 19. Although visible meteor rates [
http://leonid.arc.n
] might approach one per minute, they are predicted [
http://leonid.arc.n
] to be much less than in the previous few years.
