TL;DR: Determinations of the distances to eight long-period, late-type eclipsing systems in the Large Magellanic Cloud, composed of cool, giant stars, provide a firm base for a 3-per-cent determination of the Hubble constant.

TL;DR: The detection of a cool, sub-Neptune-mass planets may be more common than gas giant planets, as predicted by the core accretion theory, and is suggested to name OGLE-2005-BLG-390Lb, indicating a planetary mass companion to the lens star of the microlensing event.

TL;DR: It is concluded that stars are orbited by planets as a rule, rather than the exception, and that of stars host Jupiter-mass planets 0.5–10 au (Sun–Earth distance) from their stars.

TL;DR: The discovery of a population of unbound or distant Jupiter-mass objects is reported, which are almost twice as common as main-sequence stars, based on two years of gravitational microlensing survey observations towards the Galactic Bulge.

TL;DR: In this article, the authors combine VI photometry from OGLE-III with VISTA Variables in The Via Lactea survey and Two Micron All Sky Survey measurements of E(J? Ks ) to resolve the longstanding problem of the non-standard optical extinction toward the Galactic bulge.
