Analysis of the third gravitational-wave transient catalog suggests that the purported 10–12-solar-mass gap in the masses of observed black holes does not exist.
Assessment of Vera C. Rubin Observatory survey strategies suggests that longer-duration and larger-parallax gravitational microlensing events will be discovered and characterized more efficiently.
Multi-wavelength observations of a molecular cloud reveal various star-forming structures in a range of star-formation stages, including regions where massive stars are ionizing their surroundings.
A new analysis of the “IBEX ribbon” — a structure traced by energetic neutral atoms — suggests a heliosphere morphology consistent with the “croissant” model without ruling out the “comet” model.
TeV J2032+4130 is the first teraelectronvolt gamma-ray source to lack lower-energy counterparts; new data suggest that this source is likely a pulsar wind nebula.

Polycyclic aromatic hydrocarbons are created through human industrial activity and are a potential technosignature; however, research suggests that detecting these molecules in exoplanet atmospheres is infeasible.
