The same object can look very different at different times,

This answer was rated:

The same object can look very different at different times, and astronomers have worked very hard to tie different-looking objects together in the story of the evolution of the object. For example, a person is a baby, a toddler, a youth, a young adult, a middle-aged adult, and then a senior citizen. But a person never looks like a dog or a chair.


 


For each of the objects below, pick possible past or future states. Remember that you are thinking about possible past or future states of the WHOLE object. Pick the best single answer for each item.


 


1. The sun


a. Brown dwarf star


b. Supernova


c. Supergiant star


d. White dwarf star


 


2. The Crab Pulsar


a. A red dwarf star


b. A neutron star


c. White dwarf star


d. A HII region


 


3. A white dwarf with main sequence star as a close companion


a. A nova


b. A supernova


c. Nothing at all


d. All of the above


 


4. A trapezium star in the Orion Nebula


a. A globular cluster


b. A supernova


c. Brown dwarf star


d. None of the above


 


5. The Orion Nebula


a. A globular cluster

c. A blue supergiant star

6. Omega Centauri (a large and well-known globular cluster)


a. A protostar


b. The galactic halo

5d, I have found no evidence that the Orion Nebula was ever a supernova...and I have tried.
6d, this was likely a dwarf galaxy and certainly not one of the choices.

Ray Atkinson :

Pop II stars are by far older, a planetary nebula will be the future of the sun, and a 3 solar mass star lives a very short time.

Customer:

Outstanding, I had to look a little bit to see where you were coming from with #4 but I agree

Ray Atkinson :

I am sorry, but I still had the box checked that the question was not complete. You can rate the answer now. Thank you for your patience.
