ESA's ExoMars Trace Gas Orbiter and Mars Express spacecraft observed comet 3I/ATLAS during its 2020 approach to the Sun. Analysis of these observations provides valuable insights into the comet's composition, behavior, …
While reports suggest Perseverance might have spotted interstellar comet 3I/ATLAS, the likelihood is low due to observational constraints and the comet's predicted faintness. Further analysis is needed to confirm any po…
An interstellar comet is making a close pass by Mars, providing a unique opportunity for Martian orbiters and rovers to study its composition and behavior. This encounter offers valuable insights into the formation and …
The absence of non-gravitational acceleration on object 3I/ATLAS suggests it's significantly more massive than initially estimated, potentially ruling out certain exotic explanations and pointing towards a more conventi…
