Solar Oberth Route Could Intercept Interstellar Visitor 3I/ATLAS by 2035

Researchers from the Initiative for Interstellar Studies propose an indirect mission to intercept interstellar object 3I/ATLAS using a Solar Oberth maneuver and their Optimised Interplanetary Trajectory Software (OITS); a 2035 launch could align Earth, Jupiter, and the Sun to enable a high‑speed flyby, since a direct Earth‑launched rendezvous is unlikely due to late detection and the object’s high velocity. Leveraging gravity assists and a Sun-centric burn with current tech, the mission would take about 50 years, offering revolutionary insights into another star system; directed-energy propulsion remains a long‑term possibility.

Hubble View of 3I/ATLAS Reveals Structured Emission Defying Random Explanation

A newly processed Hubble Space Telescope image of interstellar object 3I/ATLAS (Jan 22, 2026) shows persistent internal structures—including a pronounced anti-tail and three emission features—after applying rotational-gradient processing to remove coma glow, suggesting non-random geometry that challenges the view of 3I/ATLAS as a typical comet; the analysis comes from NASA/ESA/STScI data and was conducted for USA Herald by Toni Scarmato as a forensic-like examination.

Scientists Investigate 3I/ATLAS for Alien Signals and Space Phenomena

Scientists have scanned the interstellar object 3I/ATLAS for alien signals using the Green Bank Telescope but found no evidence of artificial radio emissions, supporting the idea that it is a natural comet. Despite ongoing investigations and some anomalies noted by Avi Loeb, current data suggest 3I/ATLAS is likely a natural icy body rather than an alien probe.

Astronomers Hunt for Technosignatures as Interstellar Comet 3I/ATLAS Passes Earth

During its closest approach to Earth, the interstellar comet 3I/ATLAS was observed by the Breakthrough Listen project for signs of alien technosignatures, but no credible signals were detected. Simultaneously, another team estimated the comet's size to be around 1 km based on its non-gravitational acceleration, confirming its natural cometary nature. The efforts highlight ongoing searches for extraterrestrial signals and detailed studies of interstellar objects.
