Interesting Things in Space
Asteroids + Comets + Supernovas
Asteroids are rocky-metallic objects which range in size from about the size of pebbles to around 600 miles across. Although they orbit the Sun, they are too small to be considered planets. Asteroids are thought to be leftover material from the formation of our Solar System. Most are found in the Asteroid Belt, a doughnut-shaped ring which lies between the orbits of Mars and Jupiter.
Comets are left over from the formation of stars and planets billions of years ago. Before zipping around the Sun with their characteristic big tails, comets that we see in our solar system start out as big chunks of rock and ice just floating around in something called the Oort Cloud. When the gravity from a large passing body, like a star, becomes strong enough, some large chunks of ice get pulled away from the cloud and head toward the Sun. As that ball of ice gets close enough to the Sun, its heat begins to melt some of the ice that makes up the comet.
A star that suddenly increases greatly in brightness because of a catastrophic explosion that ejects most of its mass.
There are a total of 9 planets in our solar system. The biggest planet is jupiter, and the smallest planet is Pluto. Jupiter is 88,750 miles around. (360) Pluto is 1,860 miles around. Pluto’s Atmosphere is made up of frozen Methane and Ammonia. Jupiter's Atmosphere is made up of hydrogen, Helium, Methane, and Ammonia. Jupiter is -150ºC and Pluto is -350ºF.
A moon is a Astronomical shape that orbits around a planet, you can also refer it to as a natural satellite. The name moon is an reference to the planets natural satellites.
Galaxy's + Milky Way
There are at least one hundred billion galaxies in the observable universe. They’ve counted the galaxies in a particular region, and multiplied this up to estimate the number for the whole universe. It is a system of millions or billions of stars, together with gas and dust, held together by gravitational attraction.
The Milky Way is the Galaxy in which we live in, It is a spiral shaped galaxy that contains about 200 billion stars, including our Sun. It is about 100,000 light-years across and about 10,000 light-years thick.
Driving Qusetion: How big is space from where we stand?
Why I chose space: I want to learn exactly what space is meant for except for earth. I wanted to learn about how many things are in space and if space will expand or stop forever. I like the thought of space, it would be cool to go up there to see everything and to see if there is another type of planet earth out there. How big is space really, can there be more, or will we have to squish something else in space to fit it. I wonder if space is just some black hole that never stops.
There are these massive electric currents witch are formed by radiating from black holes, and One has been spotted that is about 1.5 times the size of our whole Milky Way galaxy. Pluto's so cold that the ice found on that planet is harder than most steel. This Giant Star in our universe was discovered and it is called the VY Canis Major. There is this planet called the diamond planet, The diamond planet is a planet that has diamond on it well 1/3 of the planet. The burning ice planet burns at 439 degrees Celsius, but the water molecules don't melt or evaporate, they go together to make hot ice. A Giant Water Reservoir, this is a cloud light years away and it contains 140 trillion times the amount of water on earth.
Stars + Solar System
There are a total of 9 different stars. The Protostar, the T Tauri Star, the Main Sequence Star, the Red Giant Star, the White Dwarf Star, the Red Dwarf Star, the Neutron Star, and the Super giant Star. Stars are made up of very hot gas, the gas is made up of helium and hydrogen which are the 2 most lightest elements. They shine when burning hydrogen into helium in their cores. later on they create heavier elements.
In our solar system there are total of 107 different things but I wont name them because that is alot to name, but I have them written down.
What Does NASA Do?
NASA's vision: To reach for new heights and reveal the unknown so that what we do and learn will benefit all humankind.
To do that, thousands of people have been working around the world -- and off of it -- for more than 50 years, trying to answer some basic questions. What's out there in space? How do we get there? What will we find? What can we learn there, or learn just by trying to get there, that will make life better here on Earth?
NASA stands for National Aeronautics and Space Administration. NASA was started in 1958 as a part of the United States government. NASA is in charge of U.S. science and technology that has to do with airplanes or space.
Interesting things in space 2
There is this cloud that is called the Himiko Cloud and it is over half the size of our galaxy. There is this star that is colder than your own body temperature they have been found to be only 89 degrees. 27% of the visible universe is the mysterious Dark Matter. Fast moving black holes These collapsed stars are hurling themselves through the universe eating up whatever matter or light they can. Not only do they move at speeds in the millions of miles per hour, but once they consume something, their direction changes.
A black hole is a region in space where the pulling force of gravity is so strong that light is not able to escape. The strong gravity occurs because matter has been pressed into a tiny space. This compression can take place at the end of a star's life.
Primordial black holes are thought to have formed in the early universe, soon after the big bang. Stellar black holes form when the center of a very massive star collapses in upon itself. This collapse also causes a supernova, or an exploding star, that blasts part of the star into space.
Scientists think supermassive black holes formed at the same time as the galaxy they are in. The size of the supermassive black hole is related to the size and mass of the galaxy it is in.
