I studied it some more and apparently there is a comet, 67p, that will be near the feet of virgo, as if a dragons tail. The same tail that sweeps the stars.
I read revelation 12 again and I noticed a lot of things I never noticed before. There are large gaps in the story that may make sense of this sign should it turn out to be the real thing.
Part 1. So the women gives birth to Jesus, Jesus gets taken up to heaven and satan is kicked out of heaven. satan was kicked out of heaven in Luke 10:18 because that is when Jesus began to wage ware against the heavenly powers over the nations. This is the chapter where Jesus sends out his 70/2 disciples as an invasion force in reference to the table of nations. The woman runs into the wilderness for 1260 days (half a tribulation). While in the wilderness the sign does not appear. This completes verse 1-12.
----Indeterminate gap between the first half of the tribulation and the second half of the tribulation--------
Part 2. After verse 12 The woman appears again, no longer in the wilderness but present in the sky. However she has been giving birth continually during the 1260 days in the wilderness because verse 17 declares that she has multiple offspring...each and every one of us. Now this time she doesn't have to run to the wilderness. This time she is given wings. Matthew 24:13 tells us that we will be gathered by the angels at the sound of the trumpet. If the woman is the corporate church this may be a reference to the rapture.
--------Rapture?----------
Part 3. As the woman is flying toward the wilderness the devil, who cannot reach her, tries to strike at her through a flood. However it fails. (if this is the rapture we should expect a retaliation that will fail) The woman escapes the flood and goes back into the wilderness for the later half of the tribulation where she continues to give birth. The devil now turns his attention to her offspring and makes war directly with them for the rest of the tribulation. This could be Israel and any Christian that arises after the rapture. Israel has a specific part to play after the time of the Gentiles where they turn to Christ.
