Out of the major galaxies‚ the Andromeda Galaxy is located nearest to our Milky Way. The Andromeda Galaxy is two million light years away from us‚ but it can be seen with the naked eye because it is very bright. In this galaxy there are over a hundred billion stars. It is known to be the brightest galaxy. The Andromeda Galaxy is a spiral galaxy and is part of the Local Group. It has a large star cluster in its heart and a very large hidden black hole deep in the core. The middle is very bright

PHYS1160 A black hole is a point in space where there is extreme gravitational pull‚ so extreme that light itself cannot escape. The strength of gravity is so strong due to the fact that an immense amount of matter has been contained in a small space. The existence of black holes was first theorized by John Mitchell in 1783. Mitchell accepted Newton’s laws of gravity and suggested that light escaping from the surface of a star would have its speed reduced due to the gravitation pull of the star

Earth’s galaxy. Earth’s galaxy is called the Milky Way‚ but it’s not a candy bar! Stellar black holes aren’t the biggest‚ though! There are bigger black holes called “supermassive” black holes. These kinds of black holes have the mass of OVER A MILLION SUNS TOGETHER!!!WOW!That’s a lot of mass! Scientists have discovered proof that every galaxy has a supermassive black hole in the center! The supermassive black hole found in the center of the Milky Way was named Sagittarius A‚ and do you believe me

closest full size galaxy to the Milky Way because of this it is known as our nearest galactic neighbor. The Andromeda Galaxy is also the only galaxy visible to the naked eye in the Northern Hemisphere. At 2.9 million light-years from Earth‚ Andromeda is also the farthest object that can be seen from Earth. Andromeda is not only known as our closest neighbor but scientists also refer to Andromeda and the Milky Way as sister galaxies. Andromeda closely resembles the Milky Way in shape (spiral)‚ structure

Do you like chocolate? How about Milky Ways? Enough with the chocolate talk‚ let’s talk galaxies. There are four different types of known galaxies in the world. Those galaxies are Spiral galaxies‚ Elliptical galaxies‚ Irregular galaxies‚ and Quasars. The reason there are four different types‚ is because they are classified by different characteristics. The Spiral galaxy is one that should be important to us humans‚ because we live in one. Spiral galaxies are thin and structured with four sweeping

b) Mercury- Has variety of terrains which includes crater free and heavily crater terrain. c) Europa- Is one of Jupiter’s moon which is very icy crust and a rock mantle. 4. Explain at least three ways Uranus and Neptune are different from Jupiter. -Three ways Uranus and Neptune are different than Jupiter is that first Uranus and Neptune are smaller than Jupiter. Next Jupiter is core is mostly made up of gas and Uranus and Neptune core isn’t. Uranus and Neptune are warmer

two very different objects the person and the cloud floating in the sky. The daffodils have a way of cheering him up with their happiness‚ which he sees by their dancing. The speaker is also amazed by how many daffodils there are. There is another simile in “continuous as the stars that shine and twinkle on the Milky Way‚” which compares the shape and number of the daffodils to the stars of the Milky Way. This makes the distance and separation from the world a good thing. There are several

had the time for the great Adler. I say great‚ because my experience was way more interesting and pleasing then I expected it to be. The first exhibit that I came upon was “On our Solar System” it had the clone model of the rover that is currently taking pictures and samples of the planet Mars which is also known as “The Red Planet”. There were pictures of all the moons and planets discovered in our solar system which was way more than I knew about. I saw a couple models of old telescopes that were

1) What do we mean by a geocentric universe? Contrast a geocentric view with our modern view of the universe. Geocentric describes the idea that everything revolved around Earth‚ compared to modern knowledge that everything revolves around the Sun (our star). 2) Briefly describe the major levels of structure (such as planet‚ star‚ galaxy) in the universe. Planet: (a) Orbits a star‚ (b) large enough for its own gravity to make it round‚ (c) has cleared most other objects from its orbital
