Black Hole Apocalypse | How to Detect Gravitational Waves

Learn about gravitational waves and how they can be detected in this video from NOVA: Black Hole Apocalypse. Use this resource to visualize abstract concepts related to waves and wave interactions and to provide opportunities for students to develop and use models and to communicate explanations wit

How Does Gravity Work?

Ever since the apple fell on Isaac Newton's head that fateful day, scientists have been working hard to understand the mysterious force that is gravity. Lucky for us, they've learned a great deal, and the knowledge is out there for all to see! But as with many such concepts, while most people have a

Investigating the Moon's Interior | NASA Planetary Sciences

Discover how scientists plan to use data from the GRAIL mission and a map of the Moon's gravitational field to learn about its internal structure. By comparing data about the Moon's gravity with information about its topography, scientists can gain a better understanding of the Moon's formation and

Why Does Saturn Have Rings?

Saturn is unique. Unlike the other 8 planets in our solar system Saturn has one thing going for it the others are lacking. Rings! Beautiful, multicoloured rings, make the 6th planet from the sun a cosmic marvel, but how and why are they there? Click here to see more videos: https://alugha.com/Life

Black Hole Apocalypse | Gravity and Spacetime

Learn how gravity can be described as the curving of spacetime, according to Einstein’s general theory of relativity, in this video from NOVA: Black Hole Apocalypse. Computer animations illustrate the concept of warped spacetime and how objects “fall” along a curved path. Use this resource to visual

Raising an Obelisk: An Engineering Puzzle

In this NOVA video, two teams test out two theories put forth by archaeologists to explain how ancient Egyptians might have raised massive obelisks to stable, upright positions. While only one plan works in practice, both attempts demonstrate that difficult challenges require careful planning. This

Driver Assistance Systems: Part 9 - Area View

Area View supplies live images from around the car into the cockpit. A total of four cameras provide the reassuring all-round view. And with the 180° wide-angle lenses at the front and rear, the driver’s field of vision is even extended by the areas 90° to the left and right of the vehicle's foremos

Mapping the Moon's Gravity | NASA Planetary Sciences

Launched in September 2011, find out about the Gravity Recovery and Interior Laboratory (GRAIL) mission to measure the gravitational field of the Moon and study how the Moon developed over time. Animations illustrate technical aspects of the mission's design, including the launch, orbital insertion
