Break out your solar-filtered telescopes and binoculars, (never stare directly at the sun with the naked eye,) this will only happen about eight times in your lifetime, nine if you're lucky.
Mercury is taking center stage Monday for the first time since 2006, way back when MySpace and flip phones were in style.
If you look toward the sun, your will see a tiny black dot, smaller than a flea, crossing the Sun as it passes between the Sun and Earth - that's Mercury.
The rare "planetary transit" only happens about once per decade.
Head outside before 1:30 p.m. CST to see it, or your next chance won't happen for another decade, when flying cars and high-tech eye wear to replace television and computer screens (different from Google Glass) might be all the rage.
However, scientists believe that although Mercury's display typically happens only 13 times each century, the next estimated show is set for November 2019, earlier than a full decade.
If you don't have solar-filtered telescopes or binoculars, fear not! Check out NASA's live feed until 1 p.m. CST.
