Скачать или смотреть New Study: Formation of Super-Earths is Limited Near Metal-Poor Stars

🔍 Context: Using NASA's TESS data, researchers explored planet formation around low-metallicity stars. Metal-poor stars are common in the early universe and understanding their planetary systems helps us refine our search for habitable worlds.

🔬 Research Process: The team analyzed a catalog of over 10,000 metal-poor stars. Contrary to predictions, they discovered that super-Earths are extremely rare or absent around stars with a metallicity below a certain threshold.

🧑‍🔬 Findings: The study identified a "cliff" in planet formation. Super-Earths likely didn't form during the first half of the universe's history. This finding narrows down where and when planets could form, refining our search for life beyond Earth.
