Initial VLT/MUSE Spectroscopy Of The Interstellar Object 3I/ATLAS
The interstellar comet 3I/ATLAS is only the third interstellar object to be discovered. Pre-perihelion measurements provide a unique opportunity to study its activity and composition, which may alter as it […]

Activity-Induced Near-Infrared Variability at 29P/Schwassmann-Wachmann 1, 2017-2022
29P/Schwassmann-Wachmann 1 (SW1) is both the first-discovered active Centaur and the most outburst-prone comet known.

The Current Cratering Rate on the Regular Satellites of Jupiter, Saturn, and Uranus
We aim to compute the impact rates for objects with a diameter of 1 km onto the regular satellites of Jupiter, Saturn and Uranus using our latest dynamical simulations of […]

An Estimate Of Resident Time Of The Oort Cloud New Comets In Planetary Region
We describe the result of our numerical orbit simulation which traces dynamical evolution of new comets coming from the Oort Cloud. We combine two dynamical models for this purpose.

Uncovering a Centaur’s Tracks: UCF Scientists Examine Unique Asteroid-Comet Hybrid
UCF researchers used the James Webb Space Telescope to reveal one-of-a-kind attributes of (2060) Chiron, a distant “centaur” in space sharing properties of both a comet and an asteroid, giving […]

Astrochemistry: Webb Reveals Unusual Jets of Volatile Gas from Icy Centaur 29P
Inspired by the half-human, half-horse creatures that are part of Ancient Greek mythology, the field of astronomy has its own kind of centaurs: distant objects orbiting the Sun between Jupiter […]

A Survey Of CO, CO2, And H2O In Comets And Centaurs
CO and CO2 are the two dominant carbon-bearing molecules in comae and have major roles in driving activity. Their relative abundances also provide strong observational constraints to models of solar […]
