A new study examines the possible connection between a blazar and a neutrino source, using multi-wavelength observations of the blazar to constrain the neutrino production method.
A single transit of the exoplanet WASP-17b across the face of its host star revealed that the planet has a cloudy atmosphere, and those clouds may be composed of small quartz particles.

Using data from the InSight mission to Mars, researchers have studied the trends in wind speed and atmospheric pressure on the red planet.
SN 2020bio’s unusual properties suggest that it resulted from the explosion of a lower-mass progenitor (likely around 12 solar masses) that lost most of its hydrogen envelope.
A new age of 41 million years has been calculated for the Carina association, one of the closest stellar associations to Earth; this age is consistent with the older end of previous age estimates.

A ring-like structure surrounding a protostar is difficult to explain with well-studied phenomena like molecular outflows and instead may be a sign of magnetic flux transferral.
