Episode "Cosmic Collisions"
-
Known Universe Collision Course 01
Impactor strikes proto-Earth at a shallow angle resulting in the formation of the moon.
-
Known Universe Collision Course 12
Apophis asteroid passes close to Earth in 2029. If it passes through the keyhole, it will return in 2036 and strike Earth.
-
Known Universe Collision Course 10
Very large asteroid passes close to Earth.
-
Known Universe Collision Course 23
Host, Steve Jacobs points out tiny meteorites that he has just washed off of his roof and captured on a magnet.
-
Known Universe Collision Course 19
Palomar Observatory at night. It is owned and operated by the California Institute of Technology.
-
Known Universe Collision Course 07
Impactor looms behind Venus before striking it so hard that Venus now spins in the opposite direction.
-
Known Universe Collision Course 22
Scientist using the Ames Vertical Gun Range (AVGR) was designed to conduct scientific studies of lunar impact processes in support of the Apollo missions. Using its 0.30 cal light-gas gun and powder gun, the AVGR can launch projectiles to velocities ranging from 500 to 7,000 meters per second (1,600 to 23,000 ft/s). By varying the gun's angle of elevation with respect to the target vacuum chamber, impact angles from 0¡ to 90¡ relative to the gravitational vector are possible. This unique feature is extremely important in the study of crater formation processes.

Known Universe Collision Course 11
Asteroid explodes in atmosphere, similar to the Tunguska event.
-
Known Universe Collision Course 15
Black hole formation after neutron star collision.
