Spatial Distribution and Color of Dust in Halley’s Inner Coma [PDF]

International Astronomical Union Colloquium, 1991
Abstract Composite images of the intensity of solar radiation scattered by dust in Halley’s coma are constructed by using the three-channel spectra obtained during the approach phase of the Vega 2 spacecraft. They cover a sector centered on the nucleus that has a radius of 40000 km and an angular extent of 50°.

Hubble Space Telescope Observations of the Interstellar Interloper 3I/ATLAS

The Astrophysical Journal Letters
We present high-angular-resolution observations of the third known interstellar interloper, 3I/ATLAS, from the Hubble Space Telescope. The object is clearly active at 3.8 au preperihelion, showing dust emitted from the hot, Sun-facing side of the nucleus

Occurrence of Sensorineural Hearing Loss in Viral Meningitis and Encephalitis

Journal of Medical Virology, Volume 98, Issue 10, October 2026.
ABSTRACT Hearing loss in viral neuroinfections is poorly investigated. The present study aimed to clarify if hearing loss can develop in viral meningitis and encephalitis. An OAE (oto‐acoustic emission) was measured in adult patients with viral meningitis and encephalitis on the day of admission and 30–60 days after discharge.

Evolution of the dust coma in comet 67P/Churyumov-Gerasimenko before the 2009 perihelion

, 2011
Context. Comet 67P/Churyumov-Gerasimenko is the main target of ESA’s Rosetta mission and will be encountered in May 2014. Because the spacecraft will orbit the comet nucleus before and after release of the lander Philae, it is necessary to know the ...

Ischemic Stroke and Traumatic Brain Injury: Epidemiology, Molecular Pathways, and Emerging Therapies

MedComm, Volume 7, Issue 10, October 2026.
Schematic overview of secondary brain injury after ischemic stroke and traumatic brain injury. Both conditions trigger endothelial cell dysfunction, pericyte contraction, and upregulated AQP4 expression in astrocytic end‐feet, leading to blood–brain barrier disruption.

Dust measurements in the coma of comet 67P/Churyumov-Gerasimenko inbound to the Sun [PDF]

Science, 2015
Critical measurements for understanding accretion and the dust/gas ratio in the solar nebula, where planets were forming 4.5 billion years ago, are being obtained by the GIADA (Grain Impact Analyser and Dust Accumulator) experiment on the European Space Agency’s Rosetta spacecraft orbiting comet 67P/Churyumov-Gerasimenko. Between 3.6 and 3.

Observational constraints to the dynamics of dust particles in the coma of comet 67P/Churyumov-Gerasimenko

, 2021
In this work, we aim to characterize the dust motion in the inner coma of comet 67P/Churyumov-Gerasimenko to provide constraints for theoretical 3D coma models.

Synergistic transition from type‐I‐like to type‐II‐like symptomology in a pyrethroid mixture and its impact on knockdown–mortality relationships in Musca domestica L

Pest Management Science, Volume 82, Issue 10, Page 9614-9627, October 2026.
In the present study, relationship between knockdown and mortality of insecticides was examined against the adult female housefly, Musca domestica. Type‐I pyrethroid insecticides showed a weak linkage, as early knocked down flies did not always result in mortality, while type‐II pyrethroids and organophosphates exhibited strong correlation between the ...

From Flybys to Sample Return: A Review of Space Probes and Robotic Sampling Technologies for Small Bodies

Journal of Field Robotics, Volume 43, Issue 7, Page 4475-4514, October 2026.
ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full
