Modeling of nine low-mass stars in the Orion star-forming complex suggests relatively high accretion rates, and the rates calculated from near-ultraviolet data are higher than those calculated from optical data.

Researchers rule out the possibility that GRB 220627A is a gravitationally lensed gamma-ray burst, instead favoring the scenario in which it is intrinsically long, lasting more than 1,000 seconds.

Estimates of the mass of the Local Group of galaxies based on the simulated movement of the Milky Way and Andromeda galaxies must account for the effect of the size of the simulation on the derived quantities.
New photometry suggests that the globular cluster 47 Tucanae could be the result of a merger between two separate clusters, as evidenced by the cluster’s double-peaked metallicity distribution.
Calculations of the binding energies of sulfur-containing molecules may help to solve the mystery of why sulfur is so depleted in the gas phase in the interstellar medium.
Step aside, supermassive black holes: simulations suggest that ultramassive (>100 billion solar masses) black holes can form as the result of two successive mergers of massive galaxies.
