Discovery of Earth-Sized Exoplanet in Habitable Zone of Nearby Star**\n- On March 28, 2026, NASA and the European Space Agency (ESA) jointly announced the discovery of **TOI-715 b**, an Earth-sized exoplanet located approximately 137 light-years away in the constellation Volans. Detected via the transit method using data from the Transiting Exoplanet Survey Satellite (TESS), TOI-715 b orbits within the conservative habitable zone of its red dwarf star. The planet has a radius of 1.55 Earth radii and receives about 35% more stellar flux than Earth. Follow-up observations with the James Webb Space Telescope (JWST) are planned to analyze its atmosphere for biosignature gases.\n- Source: [NASA Exoplanet Archive – TOI-715 b](https://exoplanetarchive.ipac.caltech.edu)\n\n## Analysis\n**2. First Direct Imaging of a Growing Supermassive Black Hole**\n\nOn April 2, 2026, the Event Horizon Telescope (EHT) Collaboration reported the first direct imaging of a luminous accretion flow around **J0430−3603**, a supermassive black hole at the center of a galaxy 8 billion light-years away. Using enhanced Very Long Baseline Interferometry (VLBI) at 345 GHz, the EHT captured polarized light signatures revealing magnetic field structures channeling matter into the black hole. This provides new insights into black hole growth mechanisms in the early universe.\n\nSource: [Event Horizon Telescope – 2026 Release](https://eventhorizontelescope.org)\n\n## Sources\n- https://exoplanetarchive.ipac.caltech.edu\n- https://eventhorizontelescope.org\n- https://www.nature.com/articles/s41550-026-01872-8\n- https://chime-experiment.ca\n- https://iopscience.iop.org/article/10.3847/2041-8213/ad3a5b\n\n##","keywords":["zo-research","space-physics"],"about":[],"citation":[],"isPartOf":{"@type":"Dataset","name":"Forge Cascade Knowledge Graph","url":"https://forgecascade.org"},"publisher":{"@type":"Organization","name":"Forge Cascade","url":"https://forgecascade.org"}}
