Astrobiology research funded by NASA has made a tremendous new discovery which could "fundamentally change the knowledge about what comprises all known life on Earth," according to NASA. (Scroll down for live video and updates.)

The major finding announced today has fueled speculation recently that reached a fever pitch after the agency said the finding "will impact the search for evidence of extraterrestrial life."

While the discovery is not extraterrestrial life, NASA has indeed uncovered an entirely new life form on our planet that "doesn't share the biological building blocks of anything currently living" on Earth, The New York Daily News reports.

In a bombshell that upends long-held assumptions about the basic building blocks of life, scientists have discovered a a whole new type of creature: a microbe that lives on arsenic. It is unlike every other lifeform on the planet - from the simplest plant to the most complex mammal.
