Im kinda lost after reading the source is is 1610 or 1611.

I agree with Wenchbabe that the answer is 1610.

From source -

"Early in 1611, Galileo set out for Rome from Florence...The purpose of his journey was to visit the mathematicians of the Society of Jesus, who had confirmed the astonishing discoveries Galileo had made with his telescope the previous year."

Definitely 1610. He only invented the telescope in 1609! His first actual publication of observations was Sidereus Nuncius in March 1610. He discovered the Gallilean satellites of Jupiter between the 10th and 13th of January 1610.

If by some bizarre reason the answer isn't 1610 then they've made a mistake.
