Apparent size of Andromeda Galaxy (M31) Imagine the Milky Way Galaxy is a "pizza" and it has a diameter of 30 cm. On this scale, what would be the diameter of the M31 and how far (in cm) is it from the Milky Way? What will be the angular diameter of M31 as viewed from the Milky Way? How many full Moon does M31 span? (You may assume M31 has a face-on view towards us. It has a diameter of 200,000 light years, and at a distance of 2.5 million light year from Earth.)

Stellar evolution

We may see thousands of stars in the dark sky. Our universe consists of billions of stars. Stars may appear tiny to us but they are huge balls of gasses. Sun is a star of average size. Some stars are even a thousand times larger than the sun. The stars do not exist forever they have a certain lifetime. The life span of the sun is about 10 billion years. The star undergoes various changes during its lifetime, this process is called stellar evolution. The structure of the sun-like star is shown below.

Red Shift

It is an astronomical phenomenon. In this phenomenon, increase in wavelength with corresponding decrease in photon energy and frequency of radiation of light. It is the displacement of spectrum of any kind of astronomical object to the longer wavelengths (red) side.

Question

Apparent size of Andromeda Galaxy (M31)
Imagine the Milky Way Galaxy is a "pizza" and it has a diameter of 30 cm. On this scale, what would be the
diameter of the M31 and how far (in cm) is it from the Milky Way? What will be the angular diameter of M31
as viewed from the Milky Way? How many full Moon does M31 span? (You may assume M31 has a face-on
view towards us. It has a diameter of 200,000 light years, and at a distance of 2.5 million light year from
Earth.)

Target: Whirlpool Galaxy Object Type: Galaxy Distance: 37 million light-years Constellation: Canes Venatici. DO NOT COPY AND PASTE OTHER WORK OR THINGS FROM THE INTERNET, use your own words. In 500 words, please explain the relevance of this object to the physics course material in university andits importance to astronomy. (Some question you may seek to answer are: What beyond the objectitself is learned by studying this class of objects?

Part A Decide whether the statement makes sense (or is clearly true) or does not make sense (or is clearly false). The star-gas-star cycle will keep the Milky Way looking just as bright in 100 million years as it looks now. This statement does not make sense. The blowouts of gas from the disc will deplete the gas from the disc of the Milky Way in abiut 10 million years This statement makes sense. Disk of the Milky Way consist enough gas to sustain a few billion years of star formation. This statement makes sense. Most of the bright stars of spiral arms have light expentancies significantly greater than 100 million years. This statement does not make sense. The brightest stars of spiral arms of the Milky Way have life expentancies of about 10 million years. Submit Request Answer

Which of the following statements best describes our galaxy, the Milky Way? O A bulge dominated system, with little or no disk, approximately 27,000 light years across. A disk 100,000 lightyears across filled with gas and stars, with a bulge of older stars in the galaxy centre. A disk 27,000 light years across with a bulge of gas and newly formed stars in the galaxy centre. O A spherical (elliptical) galaxy, 100,000 lightyears across, with no gas and no new stars.
