Different Types Of Superclusters

These diverse types nebulas all have one thing in common and That one thing is how they are all attracted and created by some sort of gravitational pull. Due to the excess amount of debris in the spiral arms of a spiral galaxies, such as the milky way. Hydrogen and helium from the spiral arms and the debris that is still left from the big bang gives these nebulas a way to form their dust clouds. These dust clouds help create stars and once these dust clouds are finished making a baby star the star pushes/ blows away the

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.

Simulations of galaxy formation based on the Lambda Cold Dark matter (ΛCDM) cosmological model predict that a large galaxy such as the Milky Way should have many (~ 200) dwarf satellite galaxies. However, only about 20 or 30 have been identified. Where are the rest? Warm dark matter, constituting of sterile neutrinos, is lighter and since dwarf galaxies consisting mainly of dark matter are so difficult to find by visible light, there could be enough of them to reconcile the large number of dwarf galaxies that simulations predict to exist with the small number actually observed. We are looking for a weak unidentified emission line at E = (3.55−3.57) ±0.03 keV in a stacked XMM-Newton spectrum of Dwarf galaxies, which are the satellite galaxies of our Milky Way.

Spiral galaxies have the shape of spiral, hit where they get their name from. The arms of the spiral galaxies are made of the stars, gas and dust. Depending on how tight their arms, Spiral galaxies are divided into three types: a, b, and c. Spiral galaxies have a lot of gas, dust and newly forming stars therefore they are one of the brightest galaxies in the universe. Spiral galaxies

The stage was set for a “Great Debate” that occurred at the National Academy of Sciences in Washington in 1920. At issue were the fuzzy “spiral nebulae” (which today we call galaxies): Were they close enough to be part of our own Milky Way, or were they sufficiently distant to be whole galaxies unto themselves? Shapley held that, given that his research had revised an increase in theinupward the size of the Milky Way, the spiral nebulae must be part of our own Galaxy. His opponent, Heber Curtis of California’s Lick Observatory, while incorrectly rejecting the great size of our Galaxy, correctly argued that the spirals were removed aggregates of stars similar to the Milky Way. Both men presented other scientific arguments supporting their views,

“Active galactic nuclei” are objects occupying the center of many galaxies that consist of an accreting supermassive black hole and are some of the most luminous and powerful bodies in our known Universe. In the galactic-BH accretion process, gaseous matter from the galaxy is pulled into the black hole and is converted to into radiation that is then released radially outward into the host galaxy. Due to the rapid-fire accretion onto the Supermassive Black Hole, Active Galactic Nuclei (AGN) can emit radiation into their host galaxies that span much of the electromagnetic spectrum from X-rays, IR, UV, and radio waves. Researchers have organized AGN into groups based on their

Lots of matter was in a ball and then it exploded and the universe was created. All of that matter formed planets and galaxies. Our galaxy was created 5 billion years ago. We haven't been around that long figuratively speaking. As lots of gases and mass came together it formed the sun. when the sun was formed more and more of mass and gas came to our newborn galaxy and when they came together it form planets. When More and more planets and stars were formed the galaxy started to form. When a lot of gas and other matter comes together it can create a huge star or a sun. when stars or sun start to lose their energy. They will grow and grow till they become unstable. If the star is big enough it will turn into a black hole. A black hole is so strong that it can suck in anything, even light! When something gets sucked into it it will be crushed into nothing. In 4 billion years the galaxy next to us will get sucked into our gravitational pull and will collide with our solar system. When they collide it will create one big galaxy. Our solar system will have already been gone. Here are the types of galaxies, one of galaxy types are called the magellanic cloud. It has lots and lots of stars, five billion stars to be exact. Another type of a galaxy is the spiral galaxy. The milky way galaxy is a spiral galaxy. This is a lot of solar system rotating around a black hole or a white dwarf. The main type of galaxy is the elliptical galaxy. They look like a squashed up ball, they are the largest and the brightest galaxies in the universe. In the center of the galaxy there are constant explosions of millions of stars. They out number the spiral galaxies, if someone scattered 12 tennis balls across the united states they would be more crowded than the galaxies in the

The Milky Way is flat and disk shaped collection of gas dust and stars. It is 100,000 light years across and 7,000 light years thick. The Milky Way’s dish has two major spiral arms and two minor ones that comes together in of the galaxy. In the center of the disk is a cylinder bar that has a collection of old red stars. The Milky Way is visible on a moonless night only if you are in very dark spot where you would see a faint fuzzy glow in the sky. If Sagittarius and Scorpius are visible you notice it more. Galileo noticed that the Milky Way was made up of thousands of stars that were so close together, that you could see it with the naked eye and blend together to create a glow.

Third, the observations of Novae. Shapley said that in certain lights obervées "novae" seen in the spiral nebula, implies that there is more light was far more nebulous. Curtis noted that these abnormal events pourait be a member of another class called supernovae today, they are referred to as during the debate "New Class".

Throughout the lifespan of galaxies and universes, interstellar objects are created and destroyed including stars, asteroids, nebulas, and black holes. One of the rarest interstellar creations are black holes, of which are only found in three forms. These three forms include stellar, supermassive, and intermediate black holes. Black holes are mysteries that were not fully understood until the beginning of the 20th century, when multiple scientist focused their research on them. They predicted theories and made many discoveries. These scientists include Sir Isaac Newton, Albert Einstein, John Wheeler, and Stephen Hawking. These scientists have helped us to quickly advance our knowledge on the universe and surrounding galaxies.

Supermassive Black Holes: These types are the biggest among the three. They are created at the same time as the galaxy they are in. The size of the supermassive black hole is related

Corona Borealis Galaxy Cluster (Abell 2065) is highly concentrated with galaxies. About 400,000,000 galaxies are in this.

Bottom line: The Triangulum galaxy is 2.7 million light-years away, with a diameter about half that of our Milky Way. It’s turned face-on to us and so appears faint in our sky. This post tells you how to find the Triangulum galaxy, provides charts and photos, and discusses the science of this galaxy, which is the third-largest member of our Local Group. The Triangulum galaxy M33 is of type Sc, and even a "late" representative of that type so that Tully classifies it as Scd (in the Nearby Galaxies Catalog). The pronounced arms exhibit numerous reddish HII regions (including NGC 604), as well as blueish clouds of young stars. Baade has also discovered Population II stars, and globular clusters have been found. Although no supernovae have yet been detected in the Triangulum galaxy, several supernova remnants have, and were cartographed by radio astronomers with high acuracy. At least 112 variables have been discovered in M33, including 4 novae and about 25 Cepheids. A strong X-ray source is also situated in this

There are many ways that galaxies interact with one another and some ways are better than others. A merger is one of the more violent of interactions, it occurs when two galaxies collide. They do not have the momentum to keep going and fall into one another eventually merging together completely ( Astronomy, 2009). The Antennae Galaxy is a swell example of a merger. The clash between the two has been extremely violent as stars have been ripped from their parent galaxy by the gravitational force of the other . The result is a long flowing arc of stars formed between the pair, creating long tidal tails that resemble antennae.

There are many types and morphologies of galaxies. First, there are elliptical galaxies which have elongated structures, like an ellipse. An elliptical galaxy on the Hubble Sequence, a classification system for galaxies, either range from E0, being nearly spherical, or up to E7, being
