Scientists from the University of Warwick, England, believe that many comets and asteroids in space contain water. This means that many other planets could be water-rich and suitable for life formation. Roberto Raddi (citation below) and his colleagues showed that water is likely being delivered via asteroids or comets in many other planetary systems just like it did on Earth. Researchers at University of Warwick’s Astronomy and Astrophysics Group say that their findings support the possibility of water being transported to Earth-like exoplanets through such bodies in order to establish habitable environments. Exoplanets refer to planets that orbit stars outside of our Solar System. Artist’s impression showing a water-rich, rocky asteroid being torn apart by gravity from the white dwarf star.

Asteroids consist of metals and rock material while comets contain ice, dust and organic compounds. As comets approach the Sun closer, some of their ice melts away and they lose material. Even though they are near the Sun, comets usually stay solid. A hydrogen- and oxygen-rich white dwarf. Astronomers examined observations taken by the William Herschel Telescope on the Canary Islands and found a large amount of hydrogen and oxygen in the atmosphere SDSS J 1242+5226.. White dwarfs are very tiny stars that have a dense atmosphere. They can be as small as a planet. This evidence shows that an exo-asteroid, a water-rich asteroid beyond our Solar System, was damaged and ultimately delivered its water to the white dwarf. Researchers discovered that this asteroid measured 900 kilometers in size, making it the biggest asteroid within our Solar System. Dr. Raddi said: “The amount of water found SDSS J1242+5226 is equivalent to 30-35% of the oceans on Earth.” When a comet or asteroid crashes into a planet or white dwarf, the hydrogen and oxygen mix into the atmosphere. SDSS J 1242+5226. contained large amounts of each element. Boris Gansicke from the University of Warwick’s Department of Physics was a co-author. He explained that large amounts of both elements were detected in SDSS J1242+ 5226. This new study shows that many white dwarfs contain large quantities of hydrogen in their atmospheres. It is also evidence that there may be water-rich asteroids and comets around other stars. In March, researchers from Australia’s Niels Bohr Institute and Australian National University stated that the Milky Way has billions of stars and that one to three planets orbit them in the Habitable Zone. Our galaxy ought to be alive with life. Citation: “Likely detections of water-rich asteroid material in a metallic-polluted white dwarf,” R. Raddi. B. T. Gansicke. D. Koester. J. Farihi. J. J.
