Describe how galaxies are formed. The universe is made of clusters of galaxies‚ and clusters of clusters of galaxies‚ called super clusters. Galaxies are comprised of tens of millions of stars. Between the stars‚ there are interstellar clouds of gas and dust. The smallest galaxies are called dwarfs while the largest are called giants. Our Milky Way Galaxy is one of three large galaxies in the Local Group of Galaxies. The other large galaxies are the Andromeda Galaxy‚ and Messier 33‚ also in the

The circles represent galaxies. 2.Pick four of the circles around the balloon and label these A‚ B‚ C‚ and D. 3.Hypothesize what will happen to the distances between the labeled circles when you blow up the balloon ¼ full‚ ½ full‚ and ¾ full. Record your hypotheses in the Hypothesis section of your lab report. 4.Measure the starting distances‚ in inches or centimeters‚ between each of the labeled galaxies. Record the measurements in a data chart and include

used to discover the first quasars was based on coincidences between a strong radio source and a point-like optical source. Since each radio source was associated with a star it was originally thought that quasars were objects within the galaxy hence the term ’radio stars’. Quasars or quasi-stellar radio source‚ from the method by

22648860 OBSERVATIONS AND CHARACTERISTICS OF THE SOMBRERO GALAXY (M104/NGC 4594) DOMINIC J. TAN ABSTRACT The Sombrero Galaxy (M104/NGC 4594) is an unbarred spiral galaxy and a suspected member of the galaxy group within the southern regions of the Virgo cluster. It is a nearby galaxy with a very distinctive appearance making it easy to identify. Despite being easily recognisable‚ it is still not completely understood. The exact process involved in its formation is unclear and it is not

A galaxy is a massive‚ gravitationally bound system consisting of stars‚ an interstellar medium of gas and dust‚ and dark matter. The name is from the Greek root galaxias [γαλαξίας]‚ meaning "milky‚" a reference to the Milky Way galaxy. Typical galaxies range from dwarfs with as few as ten million (107) stars up to giants with one trillion (1012) stars‚ all orbiting a common center of mass. Galaxies can also contain many multiple star systems‚ star clusters‚ and various interstellar clouds. The Sun

that galaxies are moving farther away. This was in our lab (electromagnetic spectrum and the Doppler affect). In this lab Mr. Cousino drove by us in the car and the car horn got quieter as it drove away. This shows us red shift because he is moving away from us and the wavelengths are being compressed together in front of his car and are longer behind his car. This is how all the matter and energy in our universe comes from the big bang. The sun is located within the Milky Way galaxy in the

The Andromeda Galaxy‚ once also known as The Great Nebula in Andromeda‚ is considered to be one of the largest members of what is called the Local Group. The Andromeda Galaxy‚ a spiral galaxy closet to our solar system‚ is now known to be the edge and rim of our Milky Way. Even though the Andromeda Galaxy is bigger than the Milky Way Galaxy‚ both of these galaxies have many similarities. Astronomers in today’s world base their scientific observations off of the Andromeda Galaxy to make assumptions

The Andromeda Galaxy Introduction/Abstract The Andromeda galaxy is the 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
