Water on Earth Is Older Than the Sun

Drinking Water is Older than the Sun

This gives the hope that life outside of us is possible in the universe.

A new chemical model of the early solar system has found that nearly half of all water on Earth came from interstellar ice at the time of the sun's formation. This means that the moisture in our solar system is not due to local conditions in the protoplanetary disk, but a regular part of planetary formation. This gives the hope that life outside of us is possible in the universe.

To determine the age of water in the solar system, the researchers focused on studying the hydrogen in deuterium, which is known as "heavy hydrogen" because it contains an extra neutron. The ratio of deuterium and hydrogen in interstellar ice is very high because it forms at shallow temperatures. Scientists already know this by studying the composition of comets and asteroids. The level of deuterium in the solar system's water has increased since the formation of the sun. To determine whether the sun could have independently produced the isotopic levels we see today, the researchers built a computer model that dates back to the early days of the solar system and doesn't take ancient deuterium into account. However, this model was not able to produce the amount of deuterium that is now found. Therefore, researchers estimate that between 30 and 50% of the water in our solar system was part of the ancient molecular cloud that spawned the sun and planets. The scientists published their discoveries in the journal Science.

If the formation of our solar system was typical of cosmic standards, this discovery proves that interstellar ice played a role in the construction of nearby planetary systems. And since we know that all life depends on water, this news raises the possibility that other planetary systems have everything to support life.

To paraphrase Samuel Coleridge's Old Mariner poem, "Water, water everywhere, every planet has something to drink."

And even more interesting facts about space

Ice reflects 90% of the sunlight in space. No other natural body has such reflectivity. Snow-free land reflects only 10-20% of the light.

In 1968, the Soviet spacecraft Zond-5 flew around the moon for the first time in the world. On board were two Central Asian turtles. They became the first living beings in history to return to Earth after a flight past the moon - three months before the flight of Apollo 8.

The day of Mars is 24 hours 39 minutes 35.244 seconds, which is very close to Earth.

The only married couple to fly in space was American astronauts Jan Davis and Mark Lee, who were part of the crew of the Endeavor shuttle (September 12-20, 1992).

Launched from Earth in August 2007 and landing on Mars near the North Pole in May 2008, the Phoenix probe brought a digital library of science fiction to the Red Planet.

There are 200 to 400 billion stars in our galaxy, the Milky Way, and there are billions of such galaxies in the universe.

In 10 minutes, the spacecraft can photograph up to 1 million square meters. km from the Earth's surface, while such a surface is removed from an airplane in 4 years, geographers and geologists need at least 80 years to do that.

In the entire history of satellite launches into space, only one was destroyed by a meteorite that fell into it. In 1993, the satellite of the European space agency "Olympus" had no luck.

All humans are about two inches tall in weightlessness. On Earth, gravity exerts pressure on the spine, but in space, nothing presses on it and extends its entire length.

A car traveling at an average speed of 60 miles per hour would take about 48 million years to reach our nearest star (after the sun), Proxima Centauri.

The Soviet Union was the first state to land a spacecraft on the moon. In 1959, the Luna 2 instrument crashed on the surface of the moon, and 7 years later, the Luna 9 instrument made the first soft landing on the surface of an Earth satellite, transmitting images of the lunar surface. American Surveyor I landed on the moon a few months later.
