July 2026 Report: Long‑Lived Exoplanet Atmospheres, Extended Star Birth, and a Quieter Galactic Black Hole
July 2026 findings show exoplanet atmospheres lasting billions of years, star formation persisting longer, and a less ravenous galactic black hole.
JWST uncovers supermassive black holes in the first 700 million years that outweigh their host galaxies
New JWST observations reveal supermassive black holes less than a billion years after the Big Bang that outmass their host galaxies, challenging growth models.
VLT captures black hole Swift J1727.8−1613 outburst, revealing jets that expel most of the accreted gas
VLT observations of Swift J1727.8−1613 show that a black hole can eject most of the gas it accretes, reshaping ideas of black‑hole feeding.
New entropy‑based model revises Stephen Hawking’s leaky black‑hole theory
Scientists propose an entropy‑based description of black‑hole radiation, offering a dynamic alternative to Hawking’s original leaky‑black‑hole model.
Gravitational-wave analyses uncover distinct black‑hole merger subpopulations
New analyses of LIGO‑Virgo‑KAGRA data reveal that merging black holes fall into multiple subpopulations, including a heavy group around 40 solar masses.
