Question

Imagine that you are observing a bright star in the bulge of our galaxy, eight kilo-parsecs away. While you are observing it, a much fainter star in the disk of our galaxy passes nearly in-front of the bright star. The faint star is only three kilo-parsecs away. The faint star micro- lenses the bright background star. The faint star is orbited by a Jupiter-like planet. What observations would you need to make to detect the micro-lensing event? What would you expect to see? Explain your answers.

Please write a COMPLETE explanation (NOT a few sentences and dots.)
