The Andromeda Galaxy is believed to be created around the same time as the Milky Way Galaxy. This would put it's age close to just after the "big bang" at around 13.2 billion years.
No - the difference between the two is 41.5 billion.
Halfway between one million and ten billion is 5,000,500,000 (five billion 500 thousand).
