Sensitive X-ray polarization measurements from the Imaging X-ray Polarimetry Explorer challenge the idea that black hole accretion flows typically have large-scale, strong magnetic fields.
A newly developed algorithm allows for a less computationally intensive treatment of globular clusters being stretched into thin stellar streams, achieving 10% accuracy.
Researchers investigate the mysteries of Loki Patera, a lava lake on Jupiter’s moon Io that displays islands in persistent locations for at least the past 45 years and lacks certain features that other lava lakes share.
Modeling shows that a theory-defying black hole could have formed through the evolution of a triple-star system containing stars with initial masses of 1.49, 1.05, and 21.81 solar masses.
Accounting for relativistic effects and thermal electrons dramatically alters the derived parameters of high-velocity shocks, recent research shows.
Analysis of radioactive isotopes suggests that the Sun was born in association with a 25-solar-mass star that exploded as a supernova just under 1 million years before the first solids of the solar system formed.
