Spectacular Post-Perihelion Tails of Bright Kreutz Sungrazers
, 2023 A vast majority of bright comets between the late 2nd century and the early 18th century, moving in potentially Kreutz orbits according to Hasegawa & Nakano (2001), was first sighted between 2 and 16 days after perihelion, thanks to the spectacular tails

Stratigraphy Preserved on the Jezero Crater Rim Reveals Repeated Impacts on Early Mars
Journal of Geophysical Research: Planets, Volume 131, Issue 7, July 2026.Abstract The outer slopes of the western Jezero crater rim are hypothesized to expose sections of Early‐ to Pre‐Noachian crust uplifted by the Jezero impact, providing an excellent opportunity to investigate the earliest geologic processes active on terrestrial planets.

Genotoxicity of nitroso compounds and sodium dichromate in a model combining organ cultures of human nasal epithelia and the comet assay [PDF]
, 2001 Genotoxic effects of xenobiotics are a possible step in tumor initiation in the mucosa of the upper aerodigestive tract. Using the comet assay, detecting genotoxicity in human tissue has been restricted to single incubations in vitro, but in vivo most ...

Two dust populations of particle fragments in the striated tail of Comet MRKOS 1957 V
The Astronomical Journal, 1982 The striated tail of Comet Mrkos 1957 V is investigated. The formation and motions of the striae are described by the same particle-fragmentation model that has been successfully applied to Comet West. Two new kinds of striae are discovered, one made of absorbing particles and the other of essentially nonabsorbing ones.

Effect of age on the presence of comet tails at high altitude
, 2019 Extravascular lung water (EVLW) increases in healthy adults upon exposure to high altitude, likely due to increased pulmonary vascular resistance (PVR).

A Monte Carlo approach to the analysis of the dust tail of comet P/Halley
Icarus, 1992 Abstract A quantitative analysis of three wide-field photographs of Comet P/Halley obtained between 3 and 6 May 1986 has been carried out. The digitally processed maps were used as input for the Monte Carlo approach to interpreting cometary dust tails.
