Boeing’s 737 MAX family of jets have finally been cleared to fly again in the US, following a worldwide ban that started 20 months ago. Boeing is also preparing to roll out its giant new 777x airliners.

For the first time, NASA's Hubble Space Telescope has captured time-lapse images of a large, dark storm on Neptune shrinking out of existence. A recent Hubble program called Outer Planets Atmosphere Legacy, or OPAL, provides...

The atmosphere is dynamic and forever changing to maintain balance. The ingredients of air, sunlight and water allow life to exist on Earth, but they also generate calm scenes like rainbows, as a tornado ends. All storms move moisture,...

DIY Science - Make a colored vortex ring in the pool

This unique phenomenon can be easily reproduced in a pool on a sunny day.

Downwind of isolated, small, mountainous islands, a curious feature known as an island cloud vortex can form. Visible from satellite, a series of them can line up as vortex streets of cloud vorticies.

Create half-ring vortices in a pool by sliding a plate through water and adding food coloring to the ends.

The project is called VORTEX2, but it could also be called The Amazing Chase. For five weeks in the spring of 2009, and again in spring 2010, 100 researchers and scientists from 16 universities will deploy about 40 vehicles armed with...

How do scientists mimic the physics of a hurricane on the surface of a bubble? What other types of crazy research are bubbles used for? Learn how to create colorful vortices on a bubble in your kitchen!

Prof Hal Sosabowski shows us a stunning and surprising reaction, by mixing three colourless solutions. This demonstrates autocatalysis, whereby the products of a reaction act as a catalyst for that reaction. The reaction here is the...

Over a thousand tornadoes happen every year in the United States but only few dozen take lives. Most tornadoes are brief and weak but the tornadoes that are large and powerful can wipe homes off their foundations. Tornadoes only come...

All thunderstorms create hazards of lightning. Some thunderstorms result in flash flooding, large hail, damaging wind or a tornado. See how to prepare for these threats at school, at home, or outside. Understand the difference between a...
