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

This end-of-life phase of red giant stars is relatively short, and the celestial structures that form around them are rare, so the Tobi Pitcher Nebula is an excellent example of a case study in the evolution of a star

This is the first time that such an emission of water has been seen from such a great distance, and in addition, the web allows researchers a direct view, for the first time, of how this emission feeds the water supply of the entire system of Saturn and its rings

At the time of conjunction, both planets will be seen in the west direction, just after sunset over the southwestern horizon close to the setting sun. The next closest cluster - in March 2080 * And how does this relate to the way we discover planets outside the solar system?

The images of Neptune were taken by Hubble's Wide Angle Camera #3 on June 25-26 during the planet's 16-hour orbit around its axis. The images were taken at intervals of about four hours so that they allow a full view of the planet. The images show clouds in the high latitudes of both the northern and southern hemispheres. The clouds are mainly composed of methane ice crystals.
