Question
Answer must be typed please.From the Milky Way galaxy and other General Galaxy categories, what was new and interesting for you in this section? What did you learn that you didn't know before and what is hard for you to still grasp? Do you understand the difference between the properties of the different galaxies? Do you understand how galaxy collisions and mergers can bring about the creation of new types of galaxies and change their properties? Do you understand the features of the stars in the different parts of the Milky Way like Pop 1 and 2 stars and their orbits about the Galactic center? Do you understand the properties of the Black Hole at the center of the Milky Way and how it is different or similar to a regular Black Hole? What are other famous supermassive black holes at the centers of galaxies, what is the evidence for these black holes? What is the evidence for Dark Matter at the Halo of our Milky Way Galaxy and other galaxies? What is the difference between Elliptical, Irregular and Spiral galaxies and between Barred Spiral and Regular Spiral galaxies, which ones are more likely to harbor life in them??? What are Starburst galaxies and Antennae galaxies? Do you think the Milky Way will eventually merge with other galaxies and turn into a Starburst galaxy, how will that effect life on Earth if we're still alive by then? Is our sun likely to collide with another star from the other galaxy? Is our Earth likely to be yanked from its orbit and taken hostage by another star?? How does this section inspire you, challenge you and change your perspective of the universe?? What other questions would you like to investigate into? Answer must be typed please.

Explanation / Answer
The Milky Way contains over 200 billion stars, and enough dust and gas to make billions more.
Milky Way are older than the 4.5-billion-year-old sun.
I learnt that it is older than 4.5 billions years old than sun .
Properties of Milky Way galaxy as compared to other galaxies - have smooth light distributions, where the isophotes (lines of constant SB) have (nearly) elliptical shapes. ...have no current star formation.have old stars.have little gas and dust.occur preferentially in groups and clusters
Creation of different types of galaxies - galaxies were born when vast clouds of gas and dust collapsed under their own gravitational pull, allowing stars to form. The other, which has gained strength in recent years, says the young universe contained many small "lumps" of matter, which clumped together to form galaxies.
Population I stars include the sun and tend to be luminous, hot and young, concentrated in the disks of spiral galaxies.
Population II stars tend to be found in globular clusters and the nucleus of a galaxy.
Supermassive Black Hole (SMBH) known as Sagittarius A*. This tremendous black hole measures an estimated 44 million km in diameter, and has the mass of over 4 million Suns.
An elliptical galaxy is basically all bulge with no disk. They range in shape from nearly spherical to greatly elongated football shapes, and in size from smallest to biggest known galaxies. They do not have spiral arms and have little or no star formation taking place within them.
A starburst galaxy is a galaxy undergoing an exceptionally high rate of star formation, as compared to the long-term average rate ... Starburst galaxies include M82.
The Antennae Galaxies, also known as NGC 4038/NGC 4039, are a pair of interacting galaxies in the constellation Corvus.
Universe is all about of space and time and their contents including planets, stars, galaxies, and all other forms of matter and energy.
I would to investigate about which planet is most habitable for the living being.
