If a spaceship leaves Earth now, with no lunar or Venusian boost, how long would it take to reach the halfway point for turnover and the beginning of deceleration to arrive at Mars at a relative velocity (relative to Mars) of zero.

I'm buying my parents a telescope for Christmas, but could use some advice on what would be right for them. They live down in Arizona in a small retirement community, so I don't think light pollution is much of a problem. Their backyard has a concrete slab that the previous owner used for a bolted-down telescope, so there's a level surface to place the scope. They won't be moving it much other than in and outside the house. I'm debating between a Zhumell Dobsonian Reflector (8 or 10 inch) or a Meade DS-2130LNT Reflector. My parents are not tech savvy, so I want something that is easy for them to set up and not too difficult to use and view planets/stars/galaxies, etc. I'm looking to spend $300-500, but don't have a clue as to the difference between these types of scopes. Any recommendations or explanation on the difference between them would be appreciated (8 vs 10 inch, motorized vs not, etc). Other scope recommendations are also welcome. Thanks.

From what I've read we know that the sun gives us energy but for the sun to give us continious energy it has to be given energy as well. Some scientist even say they donot know the answer to this question, is it true? If there is some source greater than you and I out there than what is it? I believe no-one has even been where the sun is.

In the UV spectrum, there are two bright bands connecting an apparent line of sunspots that seem to habutually exist on the sun's equivalent to the earth's Tropics of Cancer and Capricorn. What could cause this? It seems to divide the sun in thirds vertically.

If our universe is going to die shouldnt we as humans try to find a way that we can survive instead of worring about petty things.
