Seven million years ago, at twenty-three minutes after ten.
There is no real discovery. It is visible to the naked eye, and so can be seen by anyone on a clear, moonless night. The first recorded mention of it was in the year 964.
It is extremely likely, but we cannot yet find planets from that far away. All the planets we have found to date are in our own galaxy. The Andromeda galaxy is 2.5 million light years away whereas our galaxy is about 100,000 light years across.
Whether you're talking about Andromeda the constellation, or Andromeda the galaxy, both were 'discovered' by the first hominid who had eyes to see with, and enough brain to wonder about that particular group of stars, or that particular fuzzy patch of light, above him at night. The date is lost in antiquity. There were very few people who owned calendars at that time, and those who did had no walls to hang them on. If you are at least as well equipped as that early hominid, then you can discover both the constellation and the galaxy for yourself, at some time of night or other during at least 3/4 of the year. In order to see the galaxy, you'll need a place where the sky is roughly as dark as it was for those early hominids, before civilization came along and polluted it.
