“Crowds cheered as athletes battled it out to become the first Olympians”Incredible Olympics, page 26 Can you imagine being at the first Olympic Games? Not the one from Greek legend – although watching the demigod Hercules destroy the competition with his superhuman strength would have been quite a sight to behold. No, the very first games nearly 3,000 years ago in ancient Greece. With just five events and one nation competing, it would have been a very different affair to Tokyo 2020, though still fascinating to see the origin of this international event. Today’s top athletes might even seem superhuman compared to the first Olympic competitors, although no human Olympian is a patch on some of the animal athletes we’re showcasing this issue. Enjoy!

butterfly skin

The emerald swallowtail (Papilio palinurus) is native to Southeast Asia and gets its name from its vibrant wings. Depending on which angle you look at the insect, it will change colour, shifting between dark green, yellow and blue. This chameleon-like ability comes from the structure of its wings. Tiny microstructures called wing scales, revealed in this image, reflect blue and yellow light, often creating a green hue. However, due to the arrangement and structure of the scales, at different angles yellow and blue can be seen independently. It’s believed the purpose of this colour-shifting biology may help this butterfly avoid predators.…

black hole power

Around 2.1 billion light years away from Earth lies an elliptical galaxy 1,000 times more massive than the Milky Way, called Hercules A. At the galaxy’s core is a supermassive black hole ejecting spectacular jets of cosmic material millions of trillions of miles long. Hercules A is thought to be the brightest radio-emitting object in the constellation of Hercules, emitting almost a billion times more power in radio wavelengths than our Sun. This image was created in 2012 using imagery and information from both the Wide Field Camera 3 aboard Hubble and Very Large Array (VLA) radio telescope in New Mexico. © NASA, ESA, S. Baum and C.

falling from space

On 23 April 2021, the burner from SpaceX’s Falcon 9 rocket hurtled back towards Earth. The Falcon 9 was carrying the SpaceX Crew-2 mission astronauts – Shane Kimbrough, Megan McArthur, Akihiko Hoshide and Thomas Pesquet – to the International Space Station (ISS), the second crew SpaceX has launched. The crew were carried in the Endeavour capsule, the same capsule that was used in SpaceX’s Crew Dragon debut in 2020. The launch took place at Complex 39A at the Kennedy Space Center in Florida. Not long after blastoff, the now-empty fuel burner used to propel the rocket into space fell back to Earth in this fiery spectacle.…
