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.
Metallicity maps of the Sagittarius stream show a gradient in metallicity that corresponds to a radial metallicity gradient in the Sagittarius dwarf galaxy that was torn apart in the creation of the stream.
Cygnus X-1 is an X-ray binary and one of the first systems known to contain a stellar-mass black hole; modeling yields a variety of estimates for this black hole’s spin, ranging from less than 0.1 to 0.9.
