In fluid physics, there’s often a tug of war between different effects. For droplets falling onto a surface colder than their freezing point, the hydrodynamics of impact, sudden heat transfer, Keep reading

Jupiter in Infrared
This stunning new image of Jupiter in infrared is part of a data set combining measurements from ground- and space-based observatories. The glowing Jovian orb seen here is a composite Keep reading
Getting Cold
Just as some chemical reactions produce heat, many chemical combinations absorb heat. In “Getting Cold,” the Beauty of Science team demonstrates this by showing endothermic processes in both visible and infrared light. Combinations that Keep reading
Chemistry in Infrared
Many chemical reactions, and the flows that accompany them, are invisible to the human eye. But in infrared wavelengths those same events are vibrant and energetic. In this video from Keep reading
Staying Cool in the Outback
Daytime temperatures in the Australian outback can soar, creating a harsh environment for life. Red kangaroos use several methods to regulate their body temperature during the hottest part of the Keep reading
Saturnian Clouds
It may look like an oil slick, but the photo above actually shows the clouds of Saturn. The false-color composite image reveals the gas giant in infrared, at wavelengths longer Keep reading
Volcanic Vortex
This infrared image shows a kilometer-high volcanic vortex swirling over the Bardarbunga eruption. The bright red at the bottom is lava escaping the fissure, whereas the yellow and white regions Keep reading
Reader Question: Does Flow Viz Alter Flow?
Reader gorbax asks: I’ve been wondering for a while, actually, how do we know when the method of flow visualization doesn’t actually alter the flow of a fluid itself? This Keep reading
