The International Astronomer Group used Atacama Large Millimeter / Submillimeter Array (Alma) radio station, 12P / PONCE-BROOKS comet for ordinary water (HDO) and "heavy" water (HDO that contains the first detailed map of the distribution. The results show that the ratio of this comet Derterium and hydrogen (D / H) is almost identical to the country's ocean ratio. The work was published in Nature Astronomy magazine.
The 12p / Ponce-Brooks comet belongs to the Halley's comet class, which have an intermediate orbital paragraph (20-200 years) and rarely appear in the internal solar system. The researchers clarified that (1.71 ± 0.44) × 10⁻⁴ was the lowest value for these types of comets and located the lower definition of values registered for other comets.
"The comets are frozen remnants of 4.5 billion years ago. Because it is believed that the country has been formed from dry materials, the collisions of the comet have long been considered a possible source of water on our planet. Our results are still the strongest evidence that some Halley's type comets have been used to water like the country and could make our planet residential, "said Martin Cordies.
The study has combined the data of the NASA infrared telescope in the Alma and Hawaiian so far, confirming that water and other gases come from the ice ice, not from the gasoth's gas membrane.
These observations have been made possible by ALMA's high sensitivity and unique features that allow you to detect a weak signal of heavy water near the core. Maps like comets have not been created before.
