  • Did Water Crash Into Earth From Space?Between oceans, glaciers, polar ice caps, and lakes, watery goodness covers almost 71% of Earth's surface. Earth is the only rocky planet in our solar system with this much water. So when it comes to big questions, one of the biggest is, where did Earth's water originally come from? And one new study says, maybe, the sun? But to get there, we've got to start a little further back.For decades, planetary scientists and astrobiologists have been building two main competing hypotheses for just how Earth got so gosh dang wet. Option one, water was inside Earth when it formed in the first place. The idea goes that minerals in the mantle of our ancient primordial Earth stored hydrogen and oxygen. When those minerals melted in the natural course of geothermal activity, the hydrogen and oxygen dissolved together in the magma as water. When that magma got spewed out onto Earth's surfaces via volcanoes, the water came too. Alternatively, maybe those elements stored in Earth's minerals were vaporized by an impact from some comet or asteroid. Possibly even the big impact we think created our moon. And those vaporized elements combined and settled onto Earth's surface, resulting in our life-giving liquid.But option two is an answer that doesn't come from so close to home. Many scientists think that water was just chillin' on comets, meteorites, asteroids, etc. Out in space. When these guys crashed into us, then, hey presto, water on Earth.Where this gets a little sticky, though, is the numbers.

  • Subtitles section
  • Between oceans, glaciers, polar ice caps, and lakes, watery goodness covers almost 71% of Earth's surface.
  • And that's pretty special.
  • Earth is the only rocky planet in our solar system with this much water.
  • So when it comes to big questions, one of the biggest is, where did Earth's water originally come from?
  • And one new study says, maybe, the sun?
  • But to get there, we've got to start a little further back.
  • For decades, planetary scientists and astrobiologists have been building two main competing hypotheses for just how Earth got so gosh dang wet.
  • Option one, water was inside Earth when it formed in the first place.
  • The idea goes that minerals in the mantle of our ancient primordial Earth stored hydrogen and oxygen.
  • When those minerals melted in the natural course of geothermal activity, the hydrogen and oxygen dissolved together in the magma as water.
  • When that magma got spewed out onto Earth's surfaces via volcanoes, the water came too.

  • But option two is an answer that doesn't come from so close to home.
  • Many scientists think that water was just chillin' on comets, meteorites, asteroids, etc.
  • Out in space.
  • When these guys crashed into us, then, hey presto, water on Earth.
  • Where this gets a little sticky, though, is the numbers.
  • See, scientists have studied the remnants of asteroids and meteorites that crashed into us way back at our planet's beginning.
  • And these do contain certain kinds of hydrogen, what are called isotopes.
  • But the ratio of the hydrogen isotopes on these ancient astrophysical bodies doesn't match the ratio of water in our oceans today.
  • To get to this right ratio, the water from these crashed objects would have needed to mix with another lighter isotope of hydrogen for us to get that same water we have today.
  • So where'd that different water come from?
  • And this is where we come back to the sun.
  • It does seem pretty bizarre that our water could have come from a giant ball of burning gas, but stay with me.
  • See, our sun is constantly undergoing nuclear fusion.
  • That's an incredibly energetic process that means its outermost atmospheric layer, the corona, reaches over 1 million degrees Celsius.
  • This extreme heat is flinging particles out from the sun's surface, mostly protons and electrons, creating streams of particles that can travel all throughout our solar system at around 1.6 million kilometers per hour.
  • In 2021, a team analyzed miniscule grains of dust collected by the Hayabusa space probe from the surface of a near-Earth asteroid called Itokawa.
  • The team also irradiated this dust with protons like those we find in solar wind, and that process made water.
  • And this water fits the profile of what would have been needed to even out our hydrogen imbalance.
  • An asteroid like that definitely could have contributed to the start of our water world oasis.
  • Scientist calculations found that Itokawa may contain up to 20 liters of water for every cubic meter of rock.
  • So now, the space rocks crashing into Earth option has another strong argument in its favor.
  • But the other contending hypothesis isn't going down without a fight either, because exciting new evidence from Mars indicates that the red planet also had water right from its beginning, meaning the water-was-with-us-all-along hypothesis may apply to more than just Earth.
  • But whether water came from outside in or the inside out, if either—or both—of those happened to us, that means that there may be water on other rocky planets too, and maybe they're also a perfect distance from their star.
  • And well, as we know, where there's water, there's life.
  • So it's just another piece of the puzzle clicking into place, telling us that we are almost certainly not alone in our universe.
