Researchers propose that whether the length of a star’s magnetic activity cycle increases or decreases with stellar rotation rate depends on the star’s metallicity.

Radio observations of a shell-like supernova remnant reveal it to be located within the Local Arm of the Milky Way, and estimates of the shock history suggest that the remnant is about 10,000 years old.

Researchers explore the possibility that similar physical processes are responsible for the intriguing filamentary structures at the center of our galaxy and recently discovered in the space between galaxy clusters.

Combining two algorithms allows researchers to identify the locations of lunar swirls: areas of the Moon’s surface that are slightly more reflective than nearby regions, potentially due to magnetic anomalies.

Extensive radio observations suggest that supernova SN2004C lost mass at a highly variable rate in the time before exploding, potentially due to gravity (not gravitational!) waves or binary interaction.

Researchers demonstrate the first use of Stochastic Speckle Discrimination on an extended source, showing that this technique can distinguish between errant speckles and stellar or planetary companions.
