Newly spliced-together “Frankenspectra” spanning mid-infrared to far-ultraviolet wavelengths have been made available online and will aid in the study of dust on planetary bodies.

The IceCube Neutrino Observatory did not detect any discrete neutrino flares between 2011 and 2021; hundreds or thousands of flares are needed to explain the diffuse neutrino flux.

Researchers got a new look at the famous directly imaged giant exoplanet beta Pictoris b; the new data confirm the confusing mismatch between the planet’s dynamical mass and mass implied by models.

Sub-Neptune GJ 1214b total envelope mass fraction has been constrained to be at least 8.1% to match observations, but the composition could be various combinations of rock, ice, and volatiles.

Inverse-Compton emission from radio lobes might be responsible for the X-ray emission seen in three active galactic nuclei classified as compact symmetric objects.

Hubble Space Telescope observations reveal a three-zone disk, polar dust lanes that might point to a past minor merger, and dust pillars that may indicate large-scale feedback.
