Early observations from the Daniel K. Inouye Solar Telescope enabled the study of an umbral flash: a sudden brightening of the solar chromosphere, possibly due to shock waves, seen via its spectrum.

Using models, researchers have explored how the radiation environment and rotation rate affect the atmospheric dynamics of sub-Neptunes, a common type of planet that does not exist in our solar system.

New radio observations suggest that star formation drives molecular outflows from high-redshift, quasar-hosting galaxies with little to no contribution from the active galactic nucleus necessary.

A test of intensity interferometry — correlating the changes in a star’s intensity as seen by multiple telescopes — shows how the system can be used on telescopes of different designs.

Observations suggest that metals (elements heavier than helium) are amassed efficiently in low-mass galaxies in the early universe, leading to a low escape fraction for ionizing radiation.

New modeling of oscillations in rotating neutron stars suggests a higher frequency range than previous estimates; these oscillations may produce gravitational waves and allow us to study neutron star interiors.
