12 successful occulations by Chariklo, observed between 2014 and 2016, are used to provide profiles (physical width, opacity, edge structure) for this asteroid-like body’s rings.

~40% of massive compact star-forming galaxies at z = 2 are found to host an X-ray detected active galactic nucleus, a fraction 3.2x higher than that for extended star-forming galaxies with similar masses at this redshift.

Analysis of hard X-ray and gamma-ray data of the AGILE mission that repeatedly observed the GW170104 localization region reveals a weak event that may have been a precursor to the merger.

HAT-P-11’s starspots are distributed in latitude much like sunspots near the solar activity maximum, and the majority have sizes that closely resemble the sizes of sunspots at solar maximum.

Photogravitational assists may be more effective when the star is used as a bumper (i.e., the light sail passes “in front of” the star) rather than as a catapult (i.e., the sail passes “behind” or “around” the star).
