Using images from the James Webb Space Telescope (Webb), an international research team including Western’s Stanimir Metchev has discovered new answers to explain how some brown dwarfs form giant dust storms, contradicting previous assumptions. These […]

New balloon-mounted space radiation probes developed by the Surrey Space Center at the University of Surrey have captured their first measurements of a major solar storm, confirming the research team’s model, which indicates the flare […]

Ask someone on Earth for the time and they can give you an exact answer, thanks to our planet’s intricate timekeeping system, built with atomic clocks, GPS satellites and high-speed telecommunications networks.This post was originally […]

Nearly 4.5 million years ago, two large, hot stars brushed tantalizingly close to Earth’s sun. They left behind a trace in the clouds of gas and dust that swirl just beyond our solar system—almost like […]

Dark matter and its impact on cosmology have puzzled physicists for nearly a century. At Perimeter Institute, two researchers are trying to better understand how one potential dark matter candidate, self-interacting dark matter (SIDM), could […]

An international team including astronomers from the University of Geneva (UNIGE) and the National Center of Competence in Research PlanetS has observed giant clouds of helium escaping from the exoplanet WASP-107b. Obtained with the James […]

By analyzing the data from the SuperCOSMOS Hα Survey (SHS) and from the Gaia satellite, astronomers have inspected a bipolar planetary nebula designated PHR J1724-3859. Results of the study, published Nov. 19 on the arXiv […]

What can an ancient supernova teach scientists about Earth and celestial objects? This is what a study recently published in Astronomy & Astrophysics hopes to address as a team of scientists investigated the interaction of […]

How can star populations help astronomers re-evaluate the search for intelligent extraterrestrial life, also called technosignatures? This is what a study released on the preprint server arXiv, hopes to address as a team of scientists […]

Have scientists finally confirmed the existence of the first exomoon? This is what a study released on the preprint server arXiv, and accepted for publication in Astronomy & Astrophysics, hopes to address. A large international […]
