Only in the past three decades, however, have our telescopes been able to see planets orbiting other stars.]]> 2022-08-11 03:36:55 UTC https://padlet.com/rywind98/space/wish/2258723143 rywind98 https://padlet.com/rywind98/space/wish/2258727423 Our solar system is home to eight planets: four rocky planets close in, then two gas giants, and finally two ice giants. When we first started exploring exoplanetary systems, we assumed all solar systems would look like ours. But the more systems we discover, the more we realise our own, with its peculiar configuration, is the unusual one.]]> 2022-08-11 03:39:52 UTC https://padlet.com/rywind98/space/wish/2258727423 rywind98 https://padlet.com/rywind98/space/wish/2258731982 Of the seven planets we know about in the TRAPPIST-1 system, three orbit the star in the habitable zone, where liquid water might exist on their surface, and some of these may have atmospheres. What makes the system particularly unusual is that all of its planets are made from rock. Since Earth is also rocky, TRAPPIST-1 is a promising candidate in the hunt for alien life.]]> 2022-08-11 03:42:39 UTC https://padlet.com/rywind98/space/wish/2258731982 rywind98 https://padlet.com/rywind98/space/wish/2258736694 Of the exoplanets that have been discovered, only a handful are rocky planets like Earth or Mars. Just under a third are gas giants, like Jupiter and Saturn, and just over a third are Neptune-like. The rest are mostly super-Earths, planets that are unlike any in our solar system. These are between twice and ten times the mass of Earth. Some are made of gas, some are rock, and some are formed of a mix of both.]]> 2022-08-11 03:45:20 UTC https://padlet.com/rywind98/space/wish/2258736694 rywind98 https://padlet.com/rywind98/space/wish/2258741373 We know of 213 moons - all of them in our solar system and none elsewhere. Our gas giants have the most: Jupiter and Saturn both have 53 official moons, although Saturn also has 29 small "provisional" moons awaiting confirmation. Saturn's largest moon, Titan, is bigger than the planet Mercury and is the only body other than Earth in our solar system where water circles between clouds, rain and seas.]]> 2022-08-11 03:48:19 UTC https://padlet.com/rywind98/space/wish/2258741373 rywind98 https://padlet.com/rywind98/space/wish/2258746277 To our eyes, stars are the most obvious feature of the universe, and they are undoubtedly important. These nuclear fusion reactors created the elements that make up our bodies and the planet we live on, and one produces heat and light that life on Earth needs to survive. But to fixate on our own sun would be to deny the magnificent diversity of stars in all their stages of birth, life and death.]]> 2022-08-11 03:51:18 UTC https://padlet.com/rywind98/space/wish/2258746277 rywind98 https://padlet.com/rywind98/space/wish/2258750279 Every star we see in the night sky is part of just one galaxy - our own Milky Way. Up until around one hundred years ago, astronomers believed this was all there was. Now we know the Milky Way is just one of billions of galaxies in the universe, if not more: NASA estimates there could be two trillion.]]> 2022-08-11 03:53:33 UTC https://padlet.com/rywind98/space/wish/2258750279 rywind98 https://padlet.com/rywind98/space/wish/2258754188 About a third of all galaxies we have seen are classified as elliptical. These usually form when spiral galaxies merge together, so their shape can vary depending on the ways they merge and collide - some look almost circular, while others are much more elongated. The stars in elliptical galaxies tend to be older than in spirals because of this.]]> 2022-08-11 03:55:34 UTC https://padlet.com/rywind98/space/wish/2258754188 rywind98 https://padlet.com/rywind98/space/wish/2258759430 Galaxies that don't have a clear spiral or elliptical structure are called irregular galaxies. Most of these are dwarf galaxies, small galaxies composed of a few billion stars, and they are more easily pulled apart by external gravitational forces. However, some regular-sized galaxies are irregular in shape, too, which is usually as a result of collisions with other galaxies.]]> 2022-08-11 03:58:16 UTC https://padlet.com/rywind98/space/wish/2258759430 rywind98 https://padlet.com/rywind98/space/wish/2258762338 If we were able to observe the Milky Way from outside, we would see that it is a pretty standard, mid-range spiral galaxy containing a few hundred billion stars. But it won't always stay that way. Our galaxy is on a collision course with Andromeda, which became the first galaxy other than our own to be discovered when, in 1925, Edwin Hubble confirmed it was, in fact, a galaxy.]]> 2022-08-11 04:01:33 UTC https://padlet.com/rywind98/space/wish/2258762338 rywind98 https://padlet.com/rywind98/space/wish/2258763806 Dark matter far outweighs normal matter, but dark energy outguns both of them together. The latest figures suggest it accounts for 68 per cent of all the stuff in the universe. Just don't ask what it is, because we have no idea.

What we can say is what dark energy does. If dark matter is an invisible glue holding galaxies together, dark energy works in the opposite way, accelerating the growth rate of the universe.]]> 2022-08-11 04:04:25 UTC https://padlet.com/rywind98/space/wish/2258763806 rywind98 https://padlet.com/rywind98/space/wish/2258765601 While filaments in the cosmic web are the biggest structures in the universe, they can be broken down into smaller galaxy clusters and galaxies. The biggest individual objects in the universe are huge clouds of gas, some of which are more than 400,000 light years across. Called Lyman-alpha blobs, after a spectral line of hydrogen seen in the light they emit, the process that makes these huge clumps of hydrogen gas is a mystery.]]> 2022-08-11 04:07:16 UTC
