TL;DR: In this article, the authors present three transit observations of HD 189733 b obtained with the high-resolution spectrograph CARMENES at Calar Alto, and show that stellar activity related pseudo-signals interfere with the planetary atmospheric absorption signal.

TL;DR: In this paper, the tensile, shear, and compressive strengths of the cometary material were estimated using different surface morphologies (overhangs, collapsed structures, boulders, cliffs, and Philae's footprint) and mechani- cal considerations.

TL;DR: The Deep Impact mission shot a projectile into comet 9P/Tempel 1 in order to investigate its interior and reported the water vapour content and the cross-section of the dust created by the impact, suggesting that comets are ‘icy dirtball’ rather than ‘dirty snowballs’ as commonly believed.

TL;DR: In this article, the size-frequency distribution of boulders on a comet, 67P/Churyumov-Gerasimenko (67P), was derived from the images taken by the Rosetta/OSIRIS imaging system.
