A nearby star system is helping astronomers unravel the mystery of how water appeared in our solar system billions of years ago
Scientists observed a young star, called V883 Orionis, located 1,300 light-years away using the Atacama Large Millimeter/submillimeter Array of telescopes, or ALMA, in northern Chile. The star is surrounded by a planet-forming disk of cloud of gas and dust leftover from when the star was born. Eventually, material in the disk comes together to form comets, asteroids and planets over millions of years.
Astronomers believe comets might have been responsible for delivering water to Earth early in its history by colliding with the planet because some comets have ratios similar to water on Earth. Comets are large celestial objects made of dust and ice that orbit stars.
