Did Water Exist in Our Solar System Before the Sun?

The Sun didn’t come first, it seems.

00:00This stuff is pretty important to humans, and so is the life-giving heat of our Sun.

00:08But now, according to experts with the U.S. National Radio Astronomy Observatory,

00:12water may have come into existence before our central star.

00:15The researchers say that just 1,300 light-years away, there's a star named V883 Orionis,

00:20which is in the stages of developing its own planets as we speak.

00:23But among the dust and gas and other debris which will eventually coalesce into planets,

00:27astronomers have also identified a significant amount of water vapor.

00:31Which means if we extrapolate this data to our own solar system,

00:34it means that water was here and floating around when the Sun first ignited and planets began to form around it.

00:39Experts say that water actually plays an important role in planet formation,

00:43sticking to bits of dust as it begins to collect into a planet, making it stickier and thus collect faster.

00:48We know that at least some of the water on Earth came from comets,

00:51as we can detect certain isotopes which indicate such a delivery method.

00:55But there's just too much water on our little blue planet for all of the H2O to get here by that method,

00:59with the researchers writing, quote,

01:01This is confirmation of the idea that the water in planetary systems formed billions of years ago,

01:06before the Sun in interstellar space,

01:08and has been inherited by both comets and Earth relatively unchanged.

01:13We could bestow the tęsely

01:29but we tenían a lot of water in the entire planet...

01:32So theilisus will abraça a few ceared budgets,
