Spectropolarimetry of the eclipsed Moon — through which we can observe Earth as if it were a transiting exoplanet — shows polarization that may be from multiple scatterings as sunlight first passes through Earth’s atmosphere.

Are voids in the duration–luminosity phase space of observed optical transients real, or are we just missing these objects? Few physical models lead to optical transients that occupy voids.

Gamma-ray emission at >100 GeV was discovered from the blazar RGB J2243+203 with the VERITAS Cherenkov telescope array, allowing for upper limits of z < 0.9 to z < 1.1 to be set on its redshift.

ALMA observations have revealed an extremely young, cold, and faint protostar — which may be a transitional object right after the second collapse of its first core — in the Serpens Main cluster.

Multi-wavelength observations of two molecular clouds in the extended star-forming region S235 suggest that star-formation activity was influenced by the cloud-cloud collision process.

The formation of the Himalia family of irregular moons orbiting Jupiter may have occurred either before or during a phase in which Jupiter and its satellites interacted with large perturbers from a planetesimal disk.
