I've watched a bunch of vids about the subject. Considering Joseph and Jacob's 2 7-year periods, this could be significant. I believe Daniel's 70th week aka the Time of Jacob's trouble could be a sign announcing the final 7 week of years is being announced by the star. Also, one person confidently stated that this star was the same one the wise men saw announcing Jesus's birth--not sure if that's true or not, interesting if it is.
