It is really pathetic to see how people try to defend their fundamental beliefs without any substance. People are brainwashed to believe that vedic scriptures are full of knowledge (I was a victim too. I used to recite some parts of the scriptures like purusha suktam). In reality, the scriptures are filled with filth like procedures of sacrificial, bestiality and orgy rituals, calls upon gods to slaughter their enemies (who have stolen their herds), etc.

You can also see that the site claims that Jyotish is astronomy but it actually means astrology.
Here is the description of Saturn in one of the texts "Parashara Hora Sastra" http://archive.org/stream/ParasharaHoraSastra/BrihatParashar...

What is legit or scientific about it?
