Astronomers have detected an abundance of water in the form of gas in a disk of planet-forming material that surrounds a distant star. The disk appears to contain hundreds of times more water than in all of Earth's oceans.
The discovery could give clues as to how water moves from star-forming clouds of gas and dust to planets, and could also indicate that Earth's water may be older than the sun.
Astonishing Discovery Reveals Water in Our Solar System May Have Originated Billions of Years ...
By National Radio Astronomy Observatory March 9, 2023 V883 Ori is a remarkable protostar that boasts a temperature that is just hot enough for converting water in its circumstellar disk into gas. This gas can be studied by radio astronomers to trace the origins of the water.
Observations of water in the disk forming around protostar V883 Ori have unlocked clues about the formation of comets and planetesimals in our own Solar System. Scientists studying a nearby protostar have detected the presence of water in its circumstellar disk.
Water Existed Long Before the Solar System, Astronomers Find
Water, as we're sure it's not terribly surprising to hear, is old. But according to a fascinating new paper published in the journal Nature , it might be just a little bit older than we previously thought.
"We can now trace the origins of water in our Solar System to before the formation of the Sun," John Tobin, the study's lead author and an astronomer at the US National Radio Astronomy Observatory, said in a press release .
Astrophysicist Shows How One Small Change to Our Solar System Could Unravel It : ScienceAlert
As our catalog of planetary systems in the Milky Way grows, it becomes increasingly clear how very different our Solar System could have been.
In fact, of the nearly 4,000 planetary systems identified to date, none of them reflect the order and arrangement of planets orbiting our own Sun. That could be because Solar System analogs are currently outside our detection ability .
Study reveals the delicate balance of our solar system • Earth.com
A new experiment examines a hypothetical planet between Mars and Jupiter that would disturb our solar system and push Earth into outer space. UCR astrophysicist Stephen Kane held this experiment to address two notable gaps in planetary science.
The first is the gap between the size of terrestrial and giant gas planets. The largest terrestrial planet is Earth, and the smallest gas planet is Neptune, which is 17 times more massive than Earth. There is nothing in between.
