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.
JWST scoured the Vega debris disk system for signs of planets, but while many promising objects were found, several appear to be extragalactic background sources and none appear to be planets.
