International Journal of Chemical Kinetics, Volume 58, Issue 10, Page 881-889, October 2026.ABSTRACT In the interstellar medium, chemical reactions proceed under conditions vastly different to those on Earth; these include extremely low temperatures and densities and take place in the gas phase and on water–ice grains. Understanding the energetics and more importantly the kinetics of such reactions is of relevance to the consequences on how ...

Extreme Negative Polarization of New Interstellar Comet 3I/ATLAS
The Astrophysical Journal LettersWe present the first polarimetric observations of the third discovered interstellar object (ISO), 3I/ATLAS (C/2025 N1, or 3I), obtained preperihelion with FORS2 at the Very Large Telescope, ALFOSC at the Nordic Optical Telescope, and FoReRo2 at the 2 m ...

Interstellar dust within the life cycle of the interstellar medium
EPJ Web of Conferences, 2012 Cosmic dust is omnipresent in the Universe. Its presence influences the evolution of the astronomical objects which in turn modify its physical and chemical properties.

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

Prediscovery Activity of New Interstellar Object 3I/ATLAS: Rapid Brightening from 6 to 4 au
The Astrophysical Journal LettersWe report on the prediscovery observations and constraints of the new interstellar comet 3I/2025 N1 (ATLAS), made by the Zwicky Transient Facility, for the inbound leg of the comet out to a heliocentric distance of r _h = 17 au, or approximately a year ...

Molecular filming: A director's grammar for visualizing chemistry in motion
Bulletin of the Korean Chemical Society, Volume 47, Issue 9, Page 1042-1057, September 2026.Molecular filming names the practice, not just the product, of ultrafast structural science. In deliberate analogy to molecular editing, which rewrites connectivity in space, molecular filming records geometry in time, assembling time‐ordered structural frames into a movie of atomic motion and recasting the field as a grammar of directorial choices ...

Postperihelion Optical Low-resolution Spectroscopy of Interstellar Comet 3I/ATLAS
The Astrophysical Journal Letters3I/ATLAS is the third interstellar object discovered on UT 2025 July 1, when it was inbound at a heliocentric distance of r _h = 4.51 au. Preperihelion optical spectroscopic observations at r _h < 3 au suggested that 3I/ATLAS resembled “carbon-chain ...

Brown dwarf accretion: Nonconventional star formation over very long timescales [PDF]
Serbian Astronomical Journal, 2005 We investigate the process of accretion of interstellar gas by the Galactic population of brown dwarfs over very long timescales typical for physical eschatology.

InfoScience, Volume 3, Issue 3, September 2026.With the advancement of 6G communications, high‐precision radar, and advanced imaging technologies, there is a growing demand for compact, high‐performance light sources capable of generating high‐frequency radio waves (millimeter‐wave and terahertz waves). This article systematically introduces how to efficiently generate these high‐frequency waves on
