Detecting neutrinos from supergiant stars in the carbon-burning phase would provide valuable insights into the details of stellar evolution, but detecting these neutrinos is challenging with current technology.

For the first time, researchers have used a kite, soaring to a height of 450 meters, as an airborne platform to study the solar corona during a total solar eclipse.

Taking the gravitationally lensed redshift z = 6.2 star Earendel as an example, researchers show that the presence of sub-galactic dark matter subhalos can change the interpretation of a lensed source.

JWST collected a dozen new spectra of warm circumstellar dust circling white dwarfs with metal-polluted spectra, showing evidence for replenishment of dust grains on year or decade timescales.

Analysis of rapid-neutron-capture elements in fossilized stromatolites — layered deposits of cyanobacteria — leave open the possibility of multiple isotopic transport mechanisms in the cosmos.

Models of accretion disk spectra show that warped and broken disks do not radiate like the multicolor blackbodies used to model accreting stellar-mass black holes, unless the disks break at large radii.
