How is the age of the galaxy determined?
By analysing the oldest stars found.The older the star, the older the Galaxy.
Is there a relationship between the size or age of stars and its location in the Galaxy?
yes
Average sized stars will spend their old age as?
Red giant stars.
What is the name of milky way's twin galaxy?
andrometa. it is the biggest galaxy near the milky way it is the same age same shape but has many more stars
How big is the average irregular galaxy?
There are about 400 billion stars in galaxies
What type of galaxy includes little gas and dust and no longer produces stars?
the galaxy that contains no blue stars is I DO NOT KNOW and i would like to know the answer too
How does the size temperature age and brightness of the sun compaare to other stars in the milky way galaxy?
our sun compared to other stars falls in the category of pretty average because our sun isn't to small or to big which helps support life on earth, itis also yellow which isn't veryhot because the hottest stars are blue or white. our sun is also in its main sequence ( like 90% of the rest of the stars
What is the importance of the light red shift in determining the age and motion of stars?
Red shift is of virtually no importance in determining the age of stars within our galaxy or local group. But the red shift is crucial for measuring relative velocities of those stars with respect to us. Stars approaching us are blue shifted, such as the stars in the Andromeda Galaxy. We can also determine which direction the galaxy is spinning, as the light of stars one one side will be shifted less than the light of the stars in front, or on the other side. Starlight from galaxies well beyond our local group are uniformly shifted towards the infrared end of the visible spectrum, varying with the distance of those galaxies from us. The further away they are, the deeper red the light is from them, indicating the greater their recessional velocity. I cannot think how stellar age might correlate with red shift.
Are there more cells in the human body or more stars in our galaxy?
I don't think so. From Wikipedia (article on brain): "The cerebral cortex of the human brain contains roughly 15-33 billion neurons, perhaps more, depending on gender and age,..." The galaxy has an estimated 200 billion stars.
When was the ngc 1232 galaxy formed?
We will never know - until we have the technology to age the stars within the galaxy. Most galaxies formed very early on, soon after the big bang, so there is no reason why NGC 1232 is any different.
What will happen to a black hole when a galaxy collapes?
A galaxy doesn't just suddenly collapse. Over a long, long time - much longer than the current age of the Universe - it is expected that galaxies will gradually "evaporate", in the sense that momentum is transferred to some stars, enough to let them escape from their galaxy. The momentum of other stars decreases, and they get closer to the central black hole - many of them will be absorbed by this black hole eventually.
What is the age of stars in the irregular galaxy?
Sizes vary, of course. A typical size is a few hundred billion (10^11) stars; some of the larger ones can have more than 10^12 stars. Our galaxy is a barred spiral galaxy and it has somewhere between 200 and 400 billion stars. Andromeda is an even bigger spiral galaxy. I could not say how many stars the smallest spiral galaxy would have, or how many the largest. There are cases where two spiral galaxies are colliding.
