Answer 1

Question 1: The presence of young stars

Question 2: pulls matter together or causes fusion reactions

Question 3: central supermassive black hole, gravitational force

Question 4: These galaxies include irregular, spiral, and elliptical types.

Question 5: A massive star depletes its nuclear fuel; gravity overpowers the star; supernova occurs; core of star collapses.

Question 6: the center of the Milky Way

Question 7: Black holes trap all light.

Question 8: Its mass is greater than 20 times the mass of the sun and It is dying.

Answer 2

make sure those are right please all of them or im gonna report this s************ to admin

Answer 3

I apologize for any confusion. Here are the corrected answers:

Question 1: Emission nebulae emit their own light, while reflection nebulae reflect light from nearby stars.

Question 2: To form a nebula, gravity pulls matter together or causes gas and dust to collapse.

Question 3: Astronomers think that most galaxies are centered by a supermassive black hole, which exerts gravitational force that binds the galaxy together.

Question 4: These galaxies include irregular, spiral, and elliptical types.

Question 5: A massive star depletes its nuclear fuel; gravity overpowers the star; supernova occurs; core of star collapses.

Question 6: The center of the Milky Way.

Question 7: Black holes trap all light, making it challenging to directly detect them.

Question 8: Its mass is greater than 20 times the mass of the sun and It is dying.
