The upper limit on the dispersion measure calculated for a fast radio burst implies that the Milky Way’s circumgalactic medium contains less that 100 billion solar masses of material.

Global dust storms on Mars increase the variability in the location of the bow shock and induced magnetospheric boundary, even after storm has subsided.

Data for more than 85,000 bright stars have been released from the AST3-II telescope, which is positioned on Dome A, the highest point on the Antarctic plateau.

Researchers investigate the Ophiuchus stellar stream, which displays substructure perpendicular to its main direction, a broadened tail, and a smaller angular extent than expected.

With the MAVEN spacecraft positioned in Mars’s magnetotail and Tianwen-1 in the upstream solar wind, researchers showed how interplanetary magnetic field rotation drives plasma processes in the magnetotail.

X-ray spectra suggest that a new black hole transient was caught in the process of transitioning from the hard intermediate state to the very high state, and continued in the very high state during later flare periods.
