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.
Researchers explore the possibility that the interior of Jupiter’s highly volcanic moon, Io, contains a “magmatic sponge”: a layer consisting of melted material and interconnected solid material.
New Hubble Space Telescope observations provide some evidence for the presence of water vapor in the atmosphere of a warm Neptune exoplanet, which may eventually help uncover the planet’s evolutionary history.
