Interestingly, the hypothetical ocean would be deeper under the ice than that, implying a much lower background radiation exposure than on Earth.

Which suggests a lower mutation rate for any life forms that live there. Although of course that might depend on whether they evolved to be more mutation prone as a meta-evolutionary strategy....

Dobsonian telescopes will give you the most bang for your buck. I'd say a 6 inch aperture at a minimum for an adult. An 8 inch will get you years down the road. The sky's the limit from there. DO NOT BUY A DEPARTMENT STORE TELESCOPE, they're junk. Orion Dobs are well regarded:

A caution: like so much nowadays, telescope prices have risen a lot. You should get an extra eyepiece or two of various focal lengths, that's how you change magnification. You can also get a Barlow lens, which multiplies focal length by 2X or 3X. Telescopes and astronomy are a vast subject, barely scratching the surface here.

One of the best things you can do--find your local astronomy club, go to a meeting. They often have public star parties, attend some. The members are happy to show off their equipment and to answer questions. Learn about different types of scopes, it will help you make an informed decision when it's time to buy.

This is excellent advice. A pair of 10x50 binoculars will enable you to view the moon, nearby planets, star clusters, etc. and will be much more satisfying to use than an inexpensive telescope. Learn the sky and then select a scope. Get you some binoculars and look at stuff.
