Super slow motion look at a rocket engine startup... simulation, turbulent air, plume formation, and shock diamonds developing in the exhaust. Built and visualized in RPL software.show more

16,000 year evolution 🌌 A computer simulation shows a... turbulent molecular cloud and rotating disk of dense gas around a young star. Under the force of gravity, the disk collapses, forming spiral arms and clumps, which could result in the formation of planets or brown dwarfs.show more

This is the recent hotfire test of Astra's most... powerful Rocket 4 first stage engine. The quick green flash comes from a special compound called triethylborane (TEB). It's pyrophoric - meaning it spontaneously ignites the moment it touches air. That super-hot green flame then lights the main propellants: kerosene and liquid oxygen. Once ignited, the engine unleashes a roaring orange plume and huge clouds of smoke. These ground tests prove the engine is ready for flight - checking thrust, stability, and performance before it ever leaves the pad. Credits: astraspaceshow more

HUMMINGBIRDS IN SLOW-MO LOOK STRAIGHT UP UNREAL This guy... spent 1000 hours filming tiny birds that move faster than your WiFi. He uses a macro lens and Jedi-level focus just to capture them in super slow motion. Turns out hummingbirds look like flying emeralds when you actually stop to look. Nature’s flex is wild.

Pure Paddle Power 🚢 Look at Waverley’s magnificent triple... expansion steam engine power on at 52rpm last night. After being delayed in Portsmouth due to many shipping movements Waverley’s speed was increased to make up a little of the lost time. Her engineers captured her steam engine at an increased speed. Waverley’s main engine normally operates at 42rpm. Waverley’s engine, number 520, was built in Greenock in 1946 and installed in the ship in early 1947 before her maiden voyage on Monday 16th June 1947. The engine is open to view for passengers and continues to impress young and old as it drives the ship’s massive feathering paddle wheels.show more

ROCKET LAUNCH over Washington D.C.! Look at this... the... SpaceX Falcon 9 just launched from Cape Canaveral at 6:13 p.m., and we got to see it in the DMV! It was more than 150 miles above the ground, so its plume caught the sunlight. A more peaceful scene over DCA tonight:show more

"Some aircraft don't just fly — they carry history... with them." The aircraft in this video is a Douglas DC-6, a four-engine, piston-powered airliner built by the Douglas Aircraft Company between 1946 and 1958. Originally created for long-range commercial routes, the DC-6 soon demonstrated its versatility, serving both major airlines and the U.S. military. With a top speed of about 315 mph and a range near 2,600 miles, it stood as a technological heavyweight of its time. Even today, a few DC-6s remain in service in specialized operations—most notably with Everts Air Fuel in Alaska, where durability and dependability outweigh luxury. And that “slow-motion” look from the propellers? It’s simply a camera frame-rate illusion, giving this vintage aircraft an almost otherworldly appearance.show more
