From sunset on Mars to 95 moons of Jupiter:  10 fascinating things about the Space People look into the infinite depths of space, wondering how many incredible things are going on that are still unknown. There is a planet likely made of diamonds Diamonds may blanket the exoplanet 55 Cancri e, which is 40 light-years away from Earth. Scientists assume that 55 Cancri e is attached to a star with a high carbon-to-oxygen ratio, resulting in the formation of a carbon-rich planet. Vast volumes of water have been discovered in space Three of Jupiter’s moons (Europa, Ganymede, and Callisto) and two of Saturn’s (Enceladus (seen above) and Titan) are believed to have underwater oceans. Europa’s ocean may hold more than double the volume of water found on Earth. Blue Sunset on Mars Mars’s atmosphere is mostly made of carbon dioxide, with very little nitrogen and just minimal quantities of oxygen. Dust particles are an abundant component of the Martian atmosphere. These particles explain why sunsets seem blue on Mars’ surface. NASA has recorded spooky space ‘sounds’ To ‘hear’ what’s going on in space, NASA utilises a method known as data sonification, which converts signals from radio waves, plasma waves, and magnetic fields into audio recordings. Space is full of debris Space is rife with debris, including defunct satellites and old rocket parts. These objects continue to circle Earth at around 17,500 mph, which is ten times faster than a speeding bullet. 95 Moons of Jupiter The International Astronomical Union has officially recognised 95 of Jupiter’s moons. However, the number does not accurately reflect the intricacy of the Jovian system of moons, rings, and asteroids. Mercury has a tail Mercury’s solar wind, which drives sodium atoms off the planet’s surface, creates a comet-like tail. Centre of Milky Way galaxy has tens of thousands of black holes Recent research estimates that the Milky Way galaxy contains tens of thousands of black holes. Neptune has completed one orbit around the Sun since its discovery Neptune takes 165 years to complete a full circle around the Sun. Since its discovery in 1846, Neptune has only completed its first full post-discovery orbit in 2011. Venus spins backwards Compared to the other planets in our solar system, Venus spins in the opposite direction. How much chia seeds should you consume every day? Learn more
