Saturn's Cyclones | NASA Planetary Sciences

Learn about powerful cyclones seen at Saturn's north and south poles in this video from NASA's Jet Propulsion Laboratory. From a distance, Saturn appears to be serene; however, the Cassini spacecraft has provided detailed views that show the planet's active atmosphere. A giant cyclone (with a diamet

How does a lithium-ion battery work?

A lithium-ion battery is made up of a cathode, the positive pole, and an anode, the negative pole. The separating layer in the middle prevents a short from occurring. Author: 3Sat/Nano/Mia Media Leipzig/Reinhart Brüning/Stefan Hoge/Jochen Schmidt Translation and dubbing: alugha Click here to see

Changing Views of Pluto | NASA Planetary Sciences

Learn about seasonal changes on Pluto in this video adapted from NASA. Pluto is one of the largest members of the Kuiper belt, a region of small icy bodies in the outer solar system.

The Dynamic Sun

In this video from NOVA’s Sun Lab, learn about the Sun’s ever-changing surface and magnetic field. Images and animations illustrate how the Sun’s magnetic field lines are affected by the motion of the Sun’s plasma. Over time, the magnetic field becomes twisted and more complex, which increases solar
