SPHEREx Pre-perihelion Mapping of H2O, CO2, and CO in Interstellar Object 3I/ATLAS

The Astrophysical Journal Letters
From 2025 August 1 to August 15 UT, the SPHEREx spacecraft observed interstellar object 3I/ATLAS. Using R = 40–130 spectrophotometry at λ = 0.7–5 μ m, lightcurves, spectra, and imaging of 3I were obtained.

A Large Outburst, Coma Asymmetries, and the Color of Comet 243P/NEAT

The Planetary Science Journal
Water ice is a fundamental building material of comets and other bodies in the outer solar system. Yet the properties of cometary water ice are challenging to study, due to its volatility and the typical distances at which comets are observed.

Dust Production Rates in Jupiter-family Comets: A Two Year Study with ATLAS Photometry

The Planetary Science Journal
Jupiter-family comets (JFCs) exhibit a wide range of activity levels and mass loss over their orbits. We analyzed high-cadence observations of 42 active JFCs with the wide-field Asteroid Terrestrial-impact Last Alert System (ATLAS) in 2020–

A Portrait throughout Perihelion of the NH2-rich Interstellar Comet 2I/Borisov

The Planetary Science Journal
The interstellar comet 2I/Borisov is the first interstellar object where compositional characterisation was possible throughout its entire perihelion passage.

Pre-perihelion Emergence of the CN Gas Coma in 3I/ATLAS Temporally and Spatially Resolved by the 7-dimensional Telescope

The Astrophysical Journal
We present time series medium-band ( R ∼ 20–40) observations of the third interstellar object (ISO) 3I/ATLAS (C/2025 N1) obtained with the 7-Dimensional Telescope, which enabled spatially resolved monitoring of its gas and dust activity from 2025 July to

The Extreme Activity in Comet Hale–Bopp (C/1995 O1): Investigations of Extensive Narrowband Photoelectric Photometry

The Planetary Science Journal
Conventional narrowband photoelectric photometry of Comet Hale–Bopp (1995 O1) was obtained on 99 nights from mid-1995 to early-2000, yielding gas and dust production rates over an unprecedented range of time and distance. The appearance of Hale–Bopp (H-B)

Spatial Distribution of H2O+ Ions in the Inner Coma of C/2014 Q2 (Lovejoy)

The Astrophysical Journal
Neutral molecules that sublimate from cometary ices (mainly water at ∼1 au from the Sun) are ionized due to solar extreme-ultraviolet radiation and collisions with highly energetic electrons.

Photometric and spectroscopic monitoring of the outbursting Halley-type comet 12P/Pons-Brooks

Astronomy & Astrophysics
Context. Comet 12P/Pons-Brooks is a Halley-type comet known for its outbursting activity during its previous perihelia in 1883 and 1953. Its strong activity and favourable observing geometry gave a great opportunity to study this outburst-prone comet ...
