New data from the XRISM mission indicate that winds from supermassive black holes can expel gas from giant galaxies and limit future star formation.

A theoretical study proposes that collapsing massive stars may form gravastars rather than black holes by creating miniature universes inside themselves. The model offers the first dynamic explanation for how these exotic objects could arise from ordinary stellar matter.
Scientists have detected traces of iron-60 in Antarctic ice up to 80,000 years old, showing that the solar system is moving through material from an ancient stellar explosion. The findings come from a study published in Physical Review Letters and point to the Local Interstellar Cloud as the source of the radioactive isotope.

Researchers using the DAMPE space telescope have identified a shared spectral softening in cosmic rays across multiple particle types. The pattern appears at a rigidity of about 15 teraelectron-volts for protons through iron nuclei. This finding, published in Nature, offers new insight into how these high-energy particles behave in the galaxy.
