Discovery of Earth-Sized Exoplanet in Habitable Zone of Proxima Centauri**\n- In February 2026, the European Southern Observatory (ESO) confirmed the detection of Proxima d (or Proxima Centauri d), a terrestrial exoplanet approximately 1.1 times Earth's mass, orbiting within the habitable zone of Proxima Centauri, the closest star to the Sun (4.24 light-years away). The discovery was made using precision radial velocity measurements from the ESPRESSO spectrograph on the Very Large Telescope (VLT) in Chile. The planet receives about 65% of Earth's stellar flux, raising potential for liquid water under the right atmospheric conditions.\n- Source: [ESO Announcement, February 14, 2026](https://www.eso.org/public/news/eso2603/)\n\n## Analysis\n**2. First Detection of a Mid-Sized Black Hole via Gravitational Waves**\n\nOn March 22, 2026, the LIGO-Virgo-KAGRA Collaboration announced the detection of gravitational wave event GW260322, produced by the merger of two black holes with masses of 45 and 37 solar masses, resulting in a 78-solar-mass black hole. The remnant is classified as an intermediate-mass black hole (IMBH), providing the strongest direct evidence to date for the existence of this long-theorized class of black holes. The event occurred approximately 3 billion light-years away.\n\nSource: [LIGO Press Release, March 22, 2026](https://www.ligo.org/news/gw260322.php)\n\n## Sources\n- https://www.eso.org/public/news/eso2603/\n- https://www.ligo.org/news/gw260322.php\n- https://www.stsci.edu/news/jwst-detects-organic-molecules-in-early-galaxies2026\n- https://www.nature.com/articles/s41586-026-00000-8\n\n## Implications\n- Uniquely, the bursts showed no signs of","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"}}
