Astronomy

Astronomy is one of the oldest natural sciences and deals with the study of celestial objects (such as moons, planets, stars, nebulae, and galaxies); the physics, chemistry, mathematics, and evolution of such objects; and phenomena that originate outside the atmosphere of Earth (such as supernovae explosions, gamma ray bursts, and cosmic background radiation).

Ursid Meteor Shower
03/12/2013Sky at Night
The Ursids are often neglected due to the fact it peaks just before Christmas and the rates are much less than the Geminds, which peaks just a week before the Ursids. Observers will normally see 5-10 Ursids per hour during the late morning hours on the date of maximum activity.
Leonid Meteor Shower
03/12/2013Sky at Night
The Leonids are famous because their meteor showers, or storms, can be among the most spectacular. The outbursts of meteor activity are best seen when their parent object, comet 55P/Tempel-Tuttle, is near perihelion (closest approach to the sun).
Orionid Meteor Shower
03/12/2013Sky at Night
The Orionid Meteor Shower is a medium strength shower that can reach high strength activity. In a normal year the Orionids produce 20-25 shower members at maximum. In exceptional years, such as 2006-2009, the peak rates were on par with the Perseids (50-75 per hour).
