Here, a security barrier designed to prevent vehicle bomb and terrorist attacks gets tested against a 15,000 lbs truck (almost 7 tons). Things get… pretty messy! The truck speeds up to 50mph (80 km/h), hitting the barrier with immense force, about three times higher than what it takes to lift a Boeing 747. The barrier wobbles but doesn’t even budge, while the lorry’s engine
Sure, we’ve all heard of Egypt’s pyramids, but have you heard of Sudan’s pyramids? Well, you really should have – they’ve survived in the African desert for 3,000 years, and they’re absolutely spectacular, as we can all see, thanks to this National Geographic drone footage. These pyramids were built by Nubians, the rulers of the ancient Kushite kingdoms. The Kushites were
NASA’s New Horizons shuttle wasn’t only taking mind blowing photos of Pluto, it was also peeking at Pluto’s moons, especially Charon – the largest one. The latest set of images analyzed by NASA researchers revealed quite a busy past, filled with violence and geologic activity.
It’s a great day to be a space fan: NASA has just released all the photos taken by Apollo astronauts on lunar missions; digitized and grouped by the roll of film they were shot on, that’s over 8,400 images, featuring the blurry moon, the missed shots, and above all, the great features from a great mission! The Apollo program, also
StarTalk’s Neil deGrasse Tyson and Bill Nye The Science Guy sat down with Sally Le Page of General Electric to explore the science behind whether the post-apocalyptic world of Mad Max Fury Road is actually a likely scenario. You know, the movie where the world is turned into a desert and bands of lightly dressed people continually try to kill each other. While the scientific accuracy of Mad Max is highly debatable since the movie doesn’t give us much to chew on, the discussion was inevitably drawn to the risks of climate change.
Stretch above is one of the most interesting maps of the Roman Empire ever made, all carted in detail using modern computational techniques. It shows what the great empire used to look like during its period of maximum expansion under the reign of Septimius Severus, about 211 CE. As you can notice, the Romans’ domain covered much of Europe, from the Atlantic to the Ural Mountains and from modern day Scotland to the Sahara or the Arabian Golf.
What purpose would a water tank have in the proximity of a space shuttle launch?
Well, believe it or not, it is used to suppress the acoustical energy (sound and rocket exhaust reflected from the flame trench and Mobile Launcher Platform ) during launch
This is Parahemiphlebia – a dragonfly that lived over 100 million years ago, in the Cretaceous, and was contemporary with T-Rex and the Triceratops. The fossil was taken from the Crato Formation, in Brazil.
A couple of quadrotors wove a bridge out of polyethylene fiber rope in an intricate dance. Some 120 meters of rope were used by the quadrotors to bridge the 7.4-meter gap, neatly tying knots, links, and braiding. Ultimately, the final test was passed after an ETH Zurich’s Institute for Dynamic Systems and Control student crossed the robot-manufactured bridge.
A rosy, star-forming nebula thousands of light years away from Earth is “blossoming” in a dazzling cosmic spectacle. Messier 17, also known as the Omega Nebula, the Swan Nebula and the Horseshoe Nebula was shot in some remarkable photos revealed by the European Space Agency.
