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 & awesome "signs" in the "sun, moon & 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 years that represent the "rolling out ofthe heavenly carpet" for the return from heaven of the soon-coming King, the Lord Jesus Christ.
