Researchers at Southwest Research Institute have used NASA’s New Horizons spacecraft to measure how the solar wind weakens as it travels toward the edge of the solar system. The study, published in The Astrophysical Journal, shows that the stream of charged particles flowing from the Sun is gradually slowed by material drifting in from interstellar…

A study in Monthly Notices has identified NGTS-38 b, a rare giant world that takes about 180 days to circle its star. Led by scientists at Queen’s University Belfast, the international team found a planet about 8% wider than Jupiter and nearly five times as massive. The planet, formally cataloged as TIC-65910228 b and also…
A study in General Relativity and Gravitation proposes that a seven-dimensional form of spacetime geometry could leave black holes with tiny stable remnants, giving quantum information a place to survive after Hawking evaporation. The work, led by Richard Pinčák and colleagues, offers a theoretical route through one of the most famous conflicts between gravity and…
A new arXiv study from the South Pole Telescope collaboration reports a catalog of 7,190 confirmed galaxy clusters found in five years of observations from Antarctica. The survey used the SPT-3G camera to search for faint distortions in the cosmic microwave background, the ancient afterglow of the Big Bang. The catalog is one of the…
