TL;DR: In this article, the authors reported the first CHEOPS observation of an occultation, namely, that of the hot Jupiter WASP-189b, a $M_P \approx 2 M_J$ planet orbiting an A-type star.
Journal ArticleDOI
Lack of observational evidence for quantum structure of space-time at Plank scales
TL;DR: In this article, Liieu et al. showed that the cumulative affect of Planck-scale phenomenology can lead to the loss of phase of radiation emitted at large distances from the observer.

TL;DR: In this paper, a 2:4:6:9:12 chain of Laplace resonances was found for the TOI-178 system, with radii ranging from 1.152(-0.28/-0.23) to 0.177(+0.055/- 0.061) times the Earth's density between transiting planets c and d.
