New chemical diagnostics allow researchers to distinguish gas clouds enriched in metals by the first generation of stars exploding as pair-instability supernovae from those enriched by other types of supernovae.
A new algorithm allows for the weighted stacking of astronomical radio images while removing interfering signals; the method is demonstrated with observations of the Andromeda Galaxy.
The merging Antennae Galaxies are already home to thousands of super star clusters, and new analysis of molecular clouds in the merger region suggests that more are likely to form.
Researchers have discovered the first pulsar within one degree of the galactic center, suggesting that many more of these once-inaccessible objects exist.
Earth’s motion around the Sun impacts the light curves of microlensing events caused by free-floating planets passing in front of stars in our galaxy, as this study analyzing synthetic Roman data shows.
A months-long dust storm raised the temperature of Mars’s atmosphere and increased the density of atmospheric water vapor and carbon dioxide, affecting the location of the induced magnetospheric boundary.
