Step 2 of 5. 1 a nucleus 2 a central bulge 3 a disk both a thin and a thick disk 4 spiral arms 5 a spherical component and 6 a massive halo.
The Architecture Of The Galaxy Astronomy
The Short Answer.
. Briefly describe the main parts of our Galaxy. The two components are the disk and the bulge. Notice the similarity to our plot of height and weight for people Figure 1.
The disk surrounds the bright central bulge. This large quantity of dark matter causes an invisible halo that has been demonstrated. Our galaxy contains four major parts.
Briefly describe the main parts of our Galaxy. They come in a variety of shapes and sizes. 254 The Center of the Galaxy.
The galactic center is inside the region labeled Sagittarius A. Brighter regions are more intense in radio waves. Many filaments or threadlike features are seen as well as a number of shells.
Phases of the ISM. Sagittarius B1 and B2 are regions of active star formation. Our Sun a star and all the planets around it are part of a galaxy known as the Milky Way Galaxy.
A spherical group of up to hundreds of thousands of stars found primarily in a. A galaxy is a large group of stars gas and dust bound together by gravity. The outermost part of a spiral galaxy nearly spherical and lying beyond the spiral.
The bulge the disk which contains the thin disk and the thick disk the bar and the halo see Figure 1. This structure can be viewed as consisting of six separate parts. Our Sun is one of several hundred billion 2x10 11 stars that orbit around a disk-shaped structure we call the Milky Way galaxy which also contains large clouds of.
253 The Mass of the Galaxy. The entire Milky Way galaxy rotates in a clockwise direction. The big bang is how astronomers explain the way the universe began.
It is the idea that the universe began as just a single point then expanded and stretched to grow as large as it is right nowand it is still stretching. Found around high-mass. Uncharged electrically neutral particle believed to have very little or no mass.
The Milky Way is a large barred spiral galaxy. The matter in our Galaxy emits different kinds of radiation depending on what stage of the stargasstar cycle it is in. Our galaxy is made up of about 90 dark matter matter that cannot be seen and about 10 luminous matter or matter that we can see with our eyes.
The Andromeda Galaxy. The brightest part of the Galaxy consists of a thin circular rotating disk of stars distributed across a region about 100000 light-years in diameter and about 1000 light-years Thickthe dust and gas from which stars form are also fo. Step 3 of 5.
Step 4 of 5. Step 1 of 5. The three main parts of our galaxy are a disk bulge and halo.
The Milky Way is a flattened disk with spiral arms. -halo thin disk thick disk bulge the Sun galatic center Describe the evidence indicating that a black hole may be at the center of our Galaxy. Spiral galaxies have most of their stars in a disk.
Answer Our Milky Way Galaxy contains a barred bulge. Spiral Arms extend outward from the center. Some of these components blend into each other.
The Components of a Galaxy A galaxy may be made up of two visible components. Stars like people are not distributed over the diagram at random as they would be if they exhibited all combinations of luminosity and temperature. Elliptical galaxies do not have a disk.
A thin disk of stars gas and dust with concentrations in spiral arms. Instead we see that the stars cluster into. And a spheroidal halo of ancient stars and globular star clusters.
The disk is surrounded by the halo. The stars may be single stars double or multiple stars or may be part of clusters. Galaxy consists of thin disk a spherical halo globular star cluster nuclear bulge and a super massive black hole at the center.
All the stars planets gas clouds dust grains black holes dark matter and. Briefly describe the main parts of our Galaxy. Our Milky Way galaxy is huge massive and most importantly is in motion.
These stars including our Sun are all part of one large structure in space called a galaxy. The center of the disk is called a nucleus. The sun that provides heat to our planet belongs to one of the arms in the barred spiral galaxy.
A galaxy is a large collection of stars dust and gas held together by. A much less substantial thick disk of stars. Its disk contains dust stars and gas rotating from a center point.
All the stars we see in the night sky are in our own Milky Way Galaxy. 251 The Architecture of the Galaxy. The first three components are made up of baryons particles that make up protons and neutrons and therefore most of.
256 The Formation of the Galaxy. 255 Stellar Populations in the Galaxy. Briefly describe the main parts of our Galaxy.
Stars OB associations O B stars T 25000K make enough UV photons.
