To make the environment there even less like Earth's, it rains glass on this planet! And the glassy rain comes down in sideways torrents, blown by howling winds moving at 7000 km per hour! While the words ‘pale blue dot’ make us think of calm, tropical waters and light summer rain, this ‘deep blue dot’ is all sharp, raging storms and boiling heat. Its atmosphere is filled with something similar to glass particles, called ‘silicates’, which sparkle blue. Pluto was the planet furthest away from the Sun and also the coldest. The long answer is that once upon a time the answer to this question was simple. Well, unlike Earth, it isn't water that gives this world its lush blue colour. The short answer is that Neptune has the coldest overall average temperature and Uranus has the coldest temperature recorded. But, here we will be discussing the planets of our solar system. There are millions of other planets, asteroids, stars, galaxies and other forms of matter. You might wonder how blue oceans can survive in this extreme environment. Our Solar System is just a tiny part of the infinite Universe. It orbits very close to its star, leading its atmosphere to reach scorching temperatures of over 1000☌. The new world, or the ‘deep blue dot’, is an enormous gas giant, similar in size to Jupiter, the largest planet in our Solar System. The latest Hubble observation confirms the evidence. You might recognise image 2, it is a photograph of the Earth that was taken in 1990 by the Voyager 1 spacecraft when it was 6 billion km away! But now, for the first time ever, astronomers have uncovered the colour of a planet orbiting a distant star-and it's blue, too!īut that's where the similarities between the two planets end. Earlier observations have reported evidence for scattering of blue light on the planet. in this chapter we will examine the role of the sun in our solar system and in supporting life on earth. When seen from space, our world looks like a pale blue dot. Although no liquid water has been verified in our solar system, liquid oceans are thought to exist beneath the frozen crusts of Jupiters moon Europa and.

Earth is known as the ‘blue planet’ because of the vast oceans that cover two-thirds of its surface. published 25 February 2022 Here's a look at our solar system, from the scorching surface of Venus to the home of the largest volcano.
