Using three dedicated telescopes and two spacecraft in the Earth–Moon environment, researchers demonstrate the abilities of an image stacking method to detect space debris.

Analysis of 10 nights of observations of Europa’s auroral emission suggests that optical auroral brightness may be a proxy for electron density variations, assuming a stable atmospheric composition and density.

Magnetothermal modeling suggests that neutron stars may remain “silent” at radio frequencies for approximately 100,000 years before activating, potentially as long-period radio transients.

A newly discovered massive giant planet likely has a retrograde orbit relative to the other known planet in the system, pointing to a potentially violent dynamical history.

The galactic center star IRS 9 is locally unbound and was likely placed on its current trajectory by binary supernova disruption, two-body interactions, or stellar collisions.

Chromospheric and photospheric activity in M dwarfs appear to be correlated, with stellar rotation influencing both types of activity and metallicity impacting the intensity of chromospheric activity.
