5/2018 The Orion Nebula For my report I chose The Orion Nebula, the easiest celestial object to see at the time I went to the observatory back in March. This nebula harbors more than 3,000 stars that lie in a dusty region of mountains and valleys composed of mostly hydrogen. It is 1,500 light-years away and is the nearest star-forming region to Earth, making it the most effortlessly seen nebula of our skies (Hubble, 2006). In further detail, the celestial object contains massive stars

Did you know that black holes are invisible? “A black hole is a region in space where the pulling force of gravity is so strong that light is not able to escape.” (Dunbar) Even though there are special telescopes that help see black holes they are still shrouded in mystery. There are several mysteries about black holes but some things we know are how they are formed, why large stars collapse onto themselves to create black holes, and how they grow. Stellar black holes are formed from certain dying

In the universe there are many different kinds of stars in the universe. Stars start off as clouds of gas that are usually in the spinning “arms” of a galaxy The gases form together into a protostar which still cannot achieve nuclear fusion. These protostars look like stars with a cloud of gas and a disk around them. Eventually Protostars become what is known as a main sequence star. Main sequence star is a term that covers several kinds of stars. A main sequence star is a star that has achieved

(a group of several galaxies) using two different methods. He tried to infer this mass from the speed of the galaxies. Just like kids on a merry-go-round have to hold on to avoid being ejected, galaxies are held together in a spinning galactic cluster by the gravitational force provided by the matter it contains. If there were not enough matter to create this force, the galaxies would simply scatter. He then compared his result with the mass evaluated from the light the galaxies shed. He realised

how galaxies within the vast expanse of the Universe have undergone dramatic trasnforsatioms over the last eight billion years ro so.

Hubble Space Telescope The Hubble Space Telescope is the first major telescope that was placed in space. It has been in operation for over twenty-five years, and has greatly changed our knowledge of the universe. It can observe galaxies and stars that are very far away since it is not blocked at all by light pollution and smog that obstructs the views of the telescopes on Earth. Hubble is fascinating because it was and still is the most revolutionary telescope since Galileo first looked through

distance. Also, that galaxies that are 3 times as far from us move 3 times as fast too! Going back to the expansion part, the universe is just not expanding in one direction, but in every direction there exists! This observation proves that it has taken the equivalent amount of time to move from a common starting position to its current position And since the universe has been continuously expanding there are more and more clusters of galaxies, this. The phenomenon of the galaxies, which are moving

This is a giant star that had consumed its core .helium is accumulated in the core. The star takes on a red color after a helium burning red giant run out of helium in its core the star's core starts to collapse and heat up .They are the largest known stars .They are very similar to red giants .This star is nebulosity surrounding a star’s shell or envelope of nebulosity. This star is made of dust ,hydrogen helium and more gases . It usually can be found in between planets. Originally nebular was

Astronomy Ranking Task Doppler Shift Exercise #2 The order in which the greatest blue shift to the red shift of the five distant stars is E, D, B, C, A. The arrows in the diagram represent the speed of movement of the star, the longer the arrow the faster the movement of the star and vice versa. Furthermore, the motion of the source of light is said to be blueshifted if it is moving towards the observer, but if the source is moving away from the observer it is called redshifted (Prather p75). As

The never-ending universe is full of surprises. It is home to many galaxies with planets and stars of various size. Among all those galaxies there was one galaxy called the Evil Eye Galaxy, which is home to Planet X. In fact, billion years ago this planet was only a sphere going through the galaxy when one day it got caught in the gravitational field of the Black Star. The Black Star rays had some uncanny effects on the inhabitants of Planet X. The inhabitants of this planet are called the Zords
