Massive Star Formation DisplaysSelf-Control
New observations of a stellar nursery highlight a self-regulation mechanism that appears to resolve discrepancies between simulated and observed efficiencies of star formation. Continue reading
Dark Matter Could Cause Excess Optical Background
Axions that decay into photons could account for visible light that exceeds what’s expected to come from all known galaxies. Continue reading
First observations test JWST capabilities
Although the telescope’s early science results have exceeded expectations, even the most seasoned observers must use caution until calibrations are complete. Read more in Physics Today…
Webb Telescope Searches for Exoplanet Atmospheres
The recent detection of CO2 around a distant Jupiter-like planet spurs
optimism for detecting atmospheric gases around Earth-like planets
orbiting faraway stars. Continue reading
Early JWST targets set the stage for the next decade of observations
Data gathered by the telescope in its first five months of science will show what it’s capable of while enabling insight into ancient galaxies, newborn planets, and more. Continue reading
High Expectations for Black Hole Simulations
Andrew Chael’s simulations identify black hole features that he hopes could be spotted by the next-generation Event Horizon Telescope. Continue reading
Galactic Debris as a Dark Matter Identifier
Dynamic maps of 12 stellar streams trace paths that are determined by the distribution of mass in the Milky Way. Continue reading
Blowin’ in the Galactic Wind
Nuclear winds expel cold molecular hydrogen gas from the Galactic Center, providing new clues to how star-forming material circulates through the Galaxy. Continue reading
How a simple magnetic field configuration could trigger solar eruptions
The reconnection of single-looped field lines in the Sun’s corona can create tension forces strong enough to hurl material into space, according to a new simulation. Continue reading
Balding Black Holes Lose Their Magnetic Hair
First-principles plasma simulations show that black holes can’t keep their magnetic fields. Read more in APS Physics… Continue reading
