ALMA maps evolution of planet-forming gas disks over millions of years
Los Angeles CA (SPX) Jun 16, 2025 An international astronomy collaboration has uncovered new details about the life cycles of gas and dust disks that form planets, using observations from the Atacama Large Millimeter/submillimeter Array (ALMA). The findings, published in a dedicated issue of The Astrophysical Journal, stem from the AGE-PRO program (ALMA Survey of Gas Evolution of PROtoplanetary Disks). Through AGE-PRO, astronomers studied 30 disks around Sun-like stars to measure gas content at varying evolutionary phases. Their a ... read more |

Discovery of giant planet orbiting tiny star challenges theories on planet formationLondon, UK (SPX) Jun 11, 2025 Star TOI-6894 is just like many in our galaxy, a small red dwarf, and only ~20% of the mass of our Sun. Like many small stars, it is not expected to provide suitable conditions for the formation and ... more
Silicate clouds discovered in atmosphere of distant exoplanetDublin, Ireland (SPX) Jun 11, 2025 Astrophysicists have gained precious new insights into how distant "exoplanets" form and what their atmospheres can look like, after using the James Webb Telescope to image two young exoplanets in e ... more 
Super-Earth discovered in habitable zone of Sun-like star via TTV technique, paving way for 'Earth 2.0' searchesTokyo, Japan (SPX) Jun 04, 2025 "Are we alone?" This ancient question has occupied humanity's mind for a long time. In 1995, the discovery of the first exoplanet orbiting a Sun-like star opened the door to exploring this profound ... more 
Space pebbles and rocks play pivotal role in giant planet's formationLondon, UK (SPX) Jun 04, 2025 Scientists analysing an ultra-hot giant planet believe it was formed by absorbing lightweight gases like methane evaporating from tiny space pebbles, whilst being bombarded with large rocky objects. ... more |

Webb Finds First Clear Evidence of Frozen Water in Young Star System
Los Angeles CA (SPX) May 15, 2025 Astronomers have long theorized that frozen water exists in the debris disks surrounding young stars, but definitive evidence has remained elusive - until now. Using the James Webb Space Telescope, researchers have confirmed the presence of crystalline water ice in a dusty disk orbiting a Sun-like star, HD 181327, located 155 light-years away. This finding, published in the journal Nature, represents a major breakthrough in understanding the composition of young planetary systems. The data, captur ... read more
