I am new to astronomy, I have got some questions to ask, hope you guys could help me out. I just want to know the general idea, answers do not need to be very specific. Thank you

1) Given that Vega has the right ascension 18 hours 36 mins and declination +38.47' on the day of vernal equinox. What are the declination and right ascension of Vega on the summer solstice?

2)why we found Vega is not visible at all in Jan in the northern atmosphere.

3) what will happen in the next 10 mins if the sun stops giving out light and heat.

It would be great if I could get the answers through email . Thank you
