High-resolution imagery, thermal observations, topographic, geological, and mineralogical analyses suggest that a previously identified cave candidate is connected to the subsurface cave environment.

Stellar-mass black holes may become ensnared in gravitational traps in the disks around accreting black holes, but simulations show how binary black holes may be able to escape or remove the traps.

A newly discovered pulsar exhibits both persistent dim pulses as well as sporadic bright pulses similar to what is seen from rotating radio transients.

An analysis of coronal mass ejections during solar cycles 23 and 24 shows that the mass-loss rate of these events changes with the solar cycle, with certain latitudinal dependencies also present.

A comparison of several simulations of thin black hole accretion disk models finds general agreement, with features in common such as increasing inverse Compton scattering with increasing black hole spin.

Though many pulsars have been found in globular clusters, no pulsars have been discovered in open clusters; a new radio search may have changed that, though the pulsar candidate has not yet been confirmed.
