This high-resolution photo of our sun shows the structure of calcium plasma on the surface of the sun. Plasmas are governed by the same physics as our familiar earthbound fluids Keep reading
In the 1970s, the Voyager spacecraft discovered a hexagon near Saturn’s north pole that defied explanation for years. However, researchers have since simulated the shape in a laboratory by placing Keep reading
Astronaut Don Pettit narrates some of his experiments with air and water droplets in microgravity in this video. The lack of body forces and buoyancy in microgravity means that surface Keep reading
Jupiter, known for its colorful bands of stormy clouds, is a beautiful subject for fluid dynamics in action. As the planet turns, the cloud bands move at different relative speeds. Keep reading
Fluid dynamics play an important role in understanding phenomena like sunspots and solar prominences. The subfield of fluid dynamics concerned with the motion of electrically conducting fluids, like the plasma Keep reading
Boiling a liquid is a common enough phenomenon that we are all familiar with it. But, as with many aspects of fluid mechanics, removing gravity drastically changes the situation.
‘Hot air rises.’ It’s common knowledge. But we usually forget that this is only true thanks to Earth’s gravity. On Earth, a candle flame’s distinctive pointed shape is due to Keep reading
Shock waves are not just an earthbound phenomenon. They can be found in space as well. In this photo, gas (colored yellow) ejected from a dying star hits clouds of Keep reading
