Target board or donut? Iron meteorites reveal the early form of our solar system

  • No comments
The formation of our solar system involved the accretion of gas and dust into a preplanetary disk, with meteorites providing important insights into its early composition.
Astronomers have found water vapor in the disk around a young star right where planets are likely to form. In this image, the new observations from the ESO partner Atacama Large Millimeter/Submillimeter Array (ALMA) show the water vapor in shades of blue. Near the center of the disc, where the young star lives, the environment is hotter and the gas is brighter. The red rings are previous ALMA observations showing the distribution of dust around the star.Credit: ALMA (ESO/NAOJ/NRAO)/S. Facchini et al.

An amount of water at least three times greater than the water in all the Earth's oceans was discovered in the inner disk of the young Sun-like star HL Tauri, 450 light-years away from Earth, in the Taurus group
