[00:00:00]In 1990, [music] we knew zero planets beyond our solar system. These days, NASA has confirmed 6,000.

[00:00:08]But, here's what makes that number [music] interesting. To be in that list, a planet has to pass directly between us and its star. A perfect line.

[00:00:17]Most planets never do. So, 6,000 confirmed means hundreds of billions estimated in our galaxy alone. Among those 6,000, worlds made entirely [music] of diamond, planets covered in lava with no solid ground, >> [music] >> worlds with two suns rising at the same time, and roughly 50 of them sit in the habitable zone where liquid water could exist.

[00:00:40]50 potential Earths.

[00:00:43]We are at the very beginning.
