Jesus said that just before the 7 year Tribulation begins, one of the many signs of His nearness will be "signs in sun & moon & stars...".
(Luke 21:25).
With the increase in technology & incredible exploratory advancements in the last 100 years, astronomers & science have discovered all sorts of new and awesome "signs" in the "sun, moon and stars".
Not "new" to God since He created them in the beginning. But, "new" to mankind's discoveries.
Also, unprecedented natural occur- rences in the heavens are tak- ing place like the Leonid Showers in 2002 & the Hale-Boppcomet in 1997. [see articles below ]
More "signs" in the heavens will be recognized in the coming days that represent the "rolling out ofthe heavenly carpet" for the return from heaven of the soon-coming King, the Lord Jesus Christ.
