Galaxies And The NGC 1512 Galaxy

As of right now we can see 100 billion galaxies in our universe but then again that is only with the current telescope we have but as time goes by we will make bigger and better telescopes. Over time we will see double to even triple the number of galaxies than we can see now. As for the Nebulae, we cannot technically count all of them accurately. We can 't count all of the nebulae and galaxies but we can distinguish the different types. In my paper, I will be quoting and gaining my new knowledge from two of the greatest scientist: Stephen Hawking and Albert Einstein. Stephen Hawking is a cosmologist and a theoretical physicist, and Albert Einstein was a scientist and a physicist who liked to talk about the universe and its space time

a. The Milky Way galaxy is where our solar system is located in the universe.

The moons, asteroids and comets are smaller surrounding bodies. The Galaxy is an enormous cloud consisting of stars, gas, and dust. An accumulated gravity of its matter holds the Galaxy together. The Universe is made up of everything that exists. This includes galaxies, stars, and planets.

Scientists using NASA's Hubble Space Telescope have discovered that the i halo of gas enveloping the Andromeda galaxy, our nearest massive neighbor, is about six times larger and 1,000 times more massive than previously measured. The dark, nearly invisible halo stretches about a million light-years from its host galaxy, halfway to our own Milky Way galaxy. One of the most common types of galaxies in the universe.

The thin bands are generally young with “spiral arms, young stars, giant molecular clouds”(University of Cambridge, 2014). The thick band is older since it has stars with a lower metallicity. Given the study done in Chile, there were several conclusions made. First, that the “thin” disk stars all had similar metallicity even though there ages spanned over 8 billion years. Second, that stars older than 9 billion years had a very low metallicity, and this was described as a “steep decline”(University of Cambridge, 2014). However, given these two conclusions, the study also found that there are stars that are young with a low metallicity as well, meaning that the study is not completely cut and dry, so to speak. There is no distinguishable evidence that would allow researchers to definitely conclude the existence of a thin and thick disk or the creation of the Milky Way from the inside out.

The creation of the Milky Way is a fascinating thing to learn about. Despite Immanuel’s thought on the Milky Way that wasn’t the only guess that other people made. In 1785, William Hurschel the discoverer of Uranus, decided to make a map of the shape of the Milky Way. The only problem that William did not discover was that most of this galaxy was made up of gas and dust which hid most of the galaxies shape. Because William Herschel failed to make the drawing it wasn’t until 1920 when scientists could get a somewhat close map of the Milky Way. It was until then Edwin Hubble figured out specific evidence that this spiral galaxy is actually made up from other galaxies combined (Universe Today, 2017). So now when people ask what is the Milky

The Tadpole Galaxy is a disrupted barred spiral galaxy that is 420 million light-years from Earth towards Draco. It has a trail of stars about 280,000 light-years long and big, bright blue star clusters. Numerous young blue stars and star clusters, created by the galaxy collision, are seen in the spiral arms, as well as in the long tidal tail of stars. Each of these clusters contains up to a million stars and will redden with age to become in time globular clusters similar to those found in essentially all halos of large galaxies, including our own Milky Way. It is said that a more compact intruder galaxy crossed in front of the Tadpole Galaxy and was slung around behind the Tadpole by their mutual gravitational attraction. During this encounter,

There was a dream once. The dream had been filled with stars, an entire galaxy filled with planets all around, all condensed, all focused on one part of said galaxy…

The Milky Way is so named because across the night sky, it has a milky appearance. In 1924, astronomers found out that the Milky Way was not the only galaxy. The oldest star in the Milky Way galaxy is over 13 million years old. For the sun to orbit the milky way, it takes between 225 million and 250 million years. A Galactic Year is the time it takes for the Sun to orbit the Milky Way one time. The Milky Way is growing by merging with other galaxies through time. It is currently acquiring stars from a very small galaxy called the Sagittarius Dwarf Spheroidal. It is also eating up material from the Magellanic Clouds. The Milky Way has several satellite galaxies and is part of the Local Group of galaxies, which is a component of the Virgo Supercluster. The Milky Way is the second-largest galaxy in the Local Group. The milky way has at least 100 billion planets. The most known planets are in our solar system. They are in order from closest to the farest away from the sun. Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Planet Nine which use to be Pluto. Surrounding the Galactic disk there is a spheroidal halo of older stars and globular clusters which 90% of it lies within 100,000

In our universe, collisions or interactions between galaxies are often observed and can be predicted too. This colossal phenomenon occurs due to the large gravitational fields of the galaxies which attract other galaxies or are attracted by the fields of the other galaxies. The force of gravity is exerted when two galaxies are extremely close to each other. Near misses and crashes between any two galaxies are generally referred to as “interactions”. Collision may lead to merging and the galaxies may also bend out of shape, which is the case in most of the interactions. Dr Chris Power of International Centre for Radio Astronomy Research explained, ‘As the galaxies come together, mutual gravity leads to gas and stars being flung out in the form of tidal arms’. Some major galaxy interactions which happened in the past were between the Mice galaxies and the Antennae galaxies. The collision between the former went up to the second

This object is known as the Wolf-Lundmark-Melotte galaxy. A galaxy is a grouping of millions or billions of stars that are held together by a gravitational pull, various gases and dust are also found throughout a galaxy. This galaxy was named after the three astronomers who discovered it; this galaxy is known as a dwarf galaxy because it contains no more than a few million stars. This galaxy is located about 3 million light years from the Milky Way (Astronomy Now, 2016).

A galaxy, also called a nebula, consists of billions of stars, interstellar gas, dust, and dark matter which are all bound to form a massive cloud in which we live in. Although it cannot be very well explained, dark matter makes up at least 90% of a galaxy’s mass.

Our Milky Way galaxy is an island of stars in space with hundreds of billions of stars like our Sun.

The Milky Way is barred spiral galaxy. Concentration of star shaped bar in the center creates the shape of the galaxy. The Milky Way has 50 billion years spiral pattern rotation period. The Milky Way has between 15 billion years and 18 billion years bar pattern rotation period. Speed

The universe contains many galaxies and the galaxies have millions and billions of stars, here are 10 well known stars from the universe. First one is a stellar nebula , a stellar nebula is is a cloud of superheated gases and other elements formed by the explosive death of a massive star. A stellar nebula is not only massive clouds of dust , it’s also the place where stars are born. A nebula is latin for “fog”. A stellar nebula is also really big,it’s a huge interstellar cloud of dust and hydrogen and helium that range in size from 1 AU to 10 AU. It also appears in many different colors and shapes. Stellar nebula is really bright and is actually visible with a naked eye!. Even tho a stellar nebula might look like they’re standing still in
