TL;DR: The proximity and relative temperature of the host star suggests that WASP-3b is one of the hottest exoplanets known, and thus has the potential to place stringent constraints on exoplanet atmospheric models.

TL;DR: The third transiting exoplanet discovered by the WASP and SOPHIE collaboration, named WASP-3b, was discovered in this paper, where the radial-velocity measurements presented a variation with amplitude characteristic of a planetary-mass companion and in-phase with the light-curve.

TL;DR: The detection of asteroid spin-up supports the YORP effect as an explanation for the anomalous distribution of spin rates for asteroids under 10 kilometers in diameter and as a binary formation mechanism.

TL;DR: Data show that there was new material after impact that was compositionally different from that seen before impact, and the ratio of dust mass to gas mass in the ejecta was much larger than before impact.

TL;DR: In this paper, optical photometric observations of a small near-Earth asteroid, (54509) 2000 PH5, acquired over 4 years were obtained and it was found that the asteroid has been continuously increasing its rotation rate ω over this period by dω/dt = 2.0 (± 0.2) × 10−4 degrees per day squared.
