New discovery upends current models of star and planet formation
- A recent study led by Paolo Padoan challenges traditional models of star and planet formation, suggesting that protoplanetary disks grow actively by gathering material from their surroundings even after the star ignites.
- The study proposes that Bondi-Hoyle accretion allows young stars to continually gather gas and dust, reshaping and expanding their disks over time.
- This new perspective emphasizes the role of the surrounding environment in shaping star systems and explains discrepancies between previous models and observations.
- Turbulent gas dynamics in space play a significant role in supplying the necessary angular momentum to protoplanetary disks, enabling them to expand and evolve as seen in young stellar systems.
- Density fluctuations in turbulent gas increase the angular momentum delivered to a star's disk, contributing to the growth and longevity of the disk.
- The updated model helps resolve longstanding mysteries in astronomy, such as the size, longevity, and structural complexities of protoplanetary disks as observed in various star systems.
- Bondi-Hoyle accretion offers a more accurate explanation for the observed features of protoplanetary disks, including their size, mass, and spin dynamics.
- Understanding the growth of protoplanetary disks not only advances knowledge about star formation but also influences the search for habitable planets and the conditions for life in the universe.
- By combining high-resolution observations with advanced simulations, astronomers are gaining new insights into the interconnected processes of star and planet formation.
- The study highlights the continuous influence of the environment on the evolution of star systems and emphasizes the importance of studying the birthplaces of stars for understanding planetary formation.

May's full 'Flower Moon' will be a micromoon. Here's how to watch it rise.
- The full Flower Moon will appear in the sky on Monday (May 12), known as a 'micromoon' due to its somewhat smaller size.
- This micromoon phenomenon occurs when the moon is farthest from Earth in its elliptical orbit, creating an apogee full moon, which is set to happen at 12:56 p.m. EDT.
- To observe the full moon at its best, check moonrise and moonset times for your location, find a spot with a clear eastern horizon view, and enjoy the moon illusion where it appears larger near the horizon.
- Named after the blooming flowers in spring, the full moon also goes by several other names like Sucker Moon, Milk Moon, Mothers' Moon, Bright Moon, Hare Moon, and Grass Moon, with the next full moon being the Strawberry Moon on June 11.

Scientists detect strongest clues yet of alien life on a distant planet
- Astronomers using the James Webb Space Telescope have found chemical hints in the atmosphere of the distant planet K2-18b that may be linked to biological activity.
- The presence of dimethyl sulfide (DMS) and dimethyl disulfide (DMDS) on the planet, which are molecules produced by living organisms on Earth, has raised speculation about possible alien life.
- Scientists have reached a 'three-sigma' certainty level in detecting these molecules, indicating a 0.3% chance of it being a fluke, but they aim for a more definitive 'five-sigma' level for confirmation.
- Further observations with JWST could provide more clarity, as K2-18b is a 'Hycean' planet with a hydrogen-rich atmosphere that might harbor these sulfur-based gases indicative of life.

A change of tune: Birdsong evolves, says AI-powered study
- Birdsong evolves over time due to migration and aging in bird populations, a study by the University of Oxford reveals.
- Researchers used AI to analyze great tit birdsongs, finding that songs are shared, remain local, or are upheld by older birds' memories.
- The study, published in Current Biology, confirms long-theorized notions of bird song evolution.
- Data collected in Wytham Woods over three years showed age influences song similarity, and migration slows song evolution.
- Older birds act as musical archives, preserving outdated tunes, while younger birds introduce and adapt to new songs rapidly.
- The study highlights how demographic changes in bird populations shape their distinctive song cultures over time.
- The findings could aid conservation efforts by monitoring bird community changes through birdsong variations.
- The researchers have shared their dataset to encourage further exploration in this field of study.
- This study sheds light on the dynamic evolution of bird songs, emphasizing the impact of demographic factors like aging and migration.
