TL;DR: A measurement of the Hubble constant is reported that combines the distance to the source inferred purely from the gravitational-wave signal with the recession velocity inferred from measurements of the redshift using the electromagnetic data.

TL;DR: In this article, the photometric and spectroscopic evolution of a new optical transient (DLT17ck) is reported, which is spatially and temporally coincident with GW170817.

TL;DR: Observations of a multichord stellar occultation revealed the presence of a ring system around (10199) Chariklo, which is a Centaur—that is, one of a class of small objects orbiting primarily between Jupiter and Neptune—with an equivalent radius of 124 9 kilometres.

TL;DR: Photometric observations of a sample of asteroid pairs reveal that the primaries of pairs with mass ratios much less than 0.2 rotate rapidly, near their critical fission frequency, which concludes that asteroid pairs are formed by the rotational fission of a parent asteroid into a proto-binary system, which subsequently disrupts under its own internal system dynamics soon after formation.

TL;DR: In this article, the afterglows of four long-duration gamma-ray bursts (GRBs; GRBs 090323, 090328, 090902B, and 090926A) detected by the Gamma-Ray Burst Monitor and Large Area Telescope (LAT) instruments on the Fermi satellite were analyzed.
