        Rapid-forming giants could disrupt spiral protoplanetary discs giants

        Coventry UK (SPX) Nov 30, 2020
        Giant planets that developed early in a star system's life could solve a mystery of why spiral structures are not observed in young protoplanetary discs, according to a new study by University of Warwick astronomers. The research, published 26 November in the Astrophysical Journal Letters andpart supported by the Royal Society, provides an explanation for the lack of spiral structure that astronomers expect to see in protoplanetary discs around young stars that also suggests that scientists may ha ... read more

        Washington DC (UPI) Nov 16, 2020
        New research suggests one of life's most important building blocks, a simple amino acid called glycine, can form inside interstellar clouds well before the emergence of stars and planets. ... more
        Climate Stabilization on Distant Worlds
        Washington DC (SPX) Nov 16, 2020
        A critical component of a habitable planet is its ability to stabilize its climate over long timescales. In a new study, scientists explore whether a world covered in water can keep its climate as s ... more

        Stars and planets grow up together as siblings

        Munich, Germany (SPX) Nov 06, 2020
        Astronomers have found compelling evidence that planets start to form while infant stars are still growing. The high-resolution image obtained with the Atacama Large Millimeter/submillimeter Array (ALMA) shows a young proto-stellar disk with multiple gaps and rings of dust. This new result, just published in Nature, shows the youngest and most detailed example of dust rings acting as cosmic cradles, where the seeds of planets form and take hold. An international team of scientists led by Dominique ... read more
