Chandra explores interstellar medium of a bright low-mass X-ray binary
Using NASA's Chandra X-ray space telescope, astronomers have performed high-resolution X-ray spectroscopic observations of a bright low-mass X-ray binary known as GX 340+0. Results of the observational campaign, published ...
Information from starquakes provides theoretical evidence for 'fossilized' magnetism in stars
For the first time, new theoretical models, published in Astronomy & Astrophysics, connect the magnetism at the surface of long-dead stellar remnants (white dwarfs) with recent evidence of magnetism at the cores of their ...

Why do some stars in the galactic center survive while others are destroyed?
The center of our galaxy is an extreme place. Surrounding the supermassive black hole Sagittarius A*, stars are packed densely into a region where gravity, radiation, and dark matter all interact in complex ways. It is a ...
See and hear galaxies evolve from the dawn of the universe
The most realistic picture yet of how galaxies formed and then evolved from the beginning of time has been revealed in a suite of new and unique audiovisual simulations. These data, accepted for publication in the Monthly ...

Astronomers find the strongest evidence yet for the universe's first stars
For decades, astronomers were only able to study the universe's very first stars using theoretical models. Now, observations from the James Webb Space Telescope (JWST) have revealed what may be the most compelling evidence ...
Space telescopes track nearby quasar's dramatic X-ray state transition
By analyzing the data from various space observatories, Chinese astronomers have inspected a nearby quasar designated SDSS J000532.84+200717.4. Results of the new study, published April 1 on the arXiv preprint server, shed ...
Astronomers find evidence for three subpopulations of merging black holes
Astronomers analyzing gravitational-wave data from the LIGO-Virgo-KAGRA Collaboration have reported that merging binary black holes fall into three distinct categories. The study shows that the three subpopulations have their ...
Subaru Telescope sheds light on Jupiter Trojan asteroids' color mystery
Observations conducted with the Subaru Telescope and its first-generation wide-field camera, Suprime-Cam, have revealed new insights into the relationship between the color and size of Jupiter Trojan asteroids.
