First up, did you know that space smells like seared steak and hot metal? Yes, you read that right! Astronauts have described the scent of space as a mix of burnt steak, gunpowder, and welding fumes. This strange smell is caused by the ionization of space dust and the disintegration of metal parts on spacecraft, creating a distinct aroma that is out of this world.
Want more facts about space? Did you know that some of the most expensive items ever sold were related to space exploration? In 2019, a lunar sample bag from the Apollo 11 mission sold at auction for a whopping $1.8 million! This small bag was used to collect the first samples of moon rocks during the historic mission, making it a valuable piece of space history.
But wait, there’s more facts about space that you don’t want to miss! Did you know that there’s a planet made entirely of diamonds? Yes, you heard that right! Scientists have discovered a planet called PSR J1719-1438 that is composed of solid diamond, with a mass greater than Jupiter. This sparkling celestial body is located 4,000 light-years away from Earth, and it’s estimated that its diamond core is worth around 26.9 nonillion dollars – that’s 30 zeroes!
And last but not least, did you know that space has its own weather? That’s right, space weather can affect the Earth’s magnetic field, causing beautiful auroras and disrupting satellite and communication systems. Solar flares, coronal mass ejections, and geomagnetic storms are just some of the phenomena that can occur in space, reminding us that even the vast emptiness of space is not immune to the forces of nature.
