How did Earth's gold form? Scientists from the Harvard-Smithsonian Center for Astrophysics (CfA) will hold a news conference Wednesday (July 17) announcing new findings exploring the origin of the precious element on Earth.

The event will be aired live through the CfA's website beginning at 12:55 p.m. EDT (1655 GMT).

Although the specifics of the press conference are under wraps, CfA officials have provided a few tantalizing tidbits about the element:

  • Gold is so pliable it can be made into sewing thread! One ounce can be stretched to 50 miles!
  • The Greeks believed it was a dense combination of water and sunlight!
  • Gold is so rare, the world pours more steel in one hour than all the gold ever poured in the history of civilization.
  • It is rare on Earth and rare in the universe. And, it was not created by exploding supernovas!
