Re: Help with a complicated chart. Newbie here.
The 8th house is hard for me to understand. To traditional astrologers it was the "house of death," but even in Hellenistic times they realized they couldn't read the time and manner of death off the 8th house. It just didn't work. However, 8th house people may think about death with some frequency, or perhaps work in an occupation involving death. One of the most interesting charts I saw for an 8th house "native" was of a hospice nurse. This owuld be a good placement for many types of doctors, police , or paramedics.
The 8th is also the house of "shared resources." Following from the "death" meaning, it includes wills, inheritances, and life insurance. Also, using a derived house meaning, the 8th is the 2nd house from the 7th house of marriage. The second house indicates one's finances. So a conventional meaning of "shared resources" would be money shared with a spouse or partner. More generally shared resources include stocks and bonds, various types of insurance, or other investments that you effectively hold in common with a company or other share-holders.
My experience of 8th house people is that they tend to be very private. Sagittarius is also the sign of the philosopher so it may be that you spend time thinking deep thoughts!
Finally the 8th house has been related to sexuality. I think this is because of the association of signs and houses with different parts of the body, with the 8th house and Scorpio ruling the reproductive organs. Uranus square Venus in the 8th might suggest sexuality that mainstream society would find unusual in some way. Sometimes lesbians or bisexual women have Uranus square Venus but this isn't a hard-and-fast rule.
Your moon and MC in Capricorn, with Saturn as the traditional ruler of your Aquarian Jupiter would tend to tone down an outgoing Sagittarian sun, as well. So would your Taurus rising, with the ruler of the first house (Venus) in the 8th.
I'd go with exploring hidden mysteries of the universe as fairly important to you (reinforced by Jupiter square Neptune) and Pluto square sun. Or you wouldn't be here!
