Interstellar Visitor 3I/ATLAS Emerges Intact With HiRISE Images Expected Within Days

Most researchers describe the object as an active comet despite a high-profile claim that its jets are technological thrusters.

Overview

  • Fresh telescope images from the Nordic Optical Telescope show a single, intact body after perihelion, with a prominent sunward anti-tail.
  • Avi Loeb reiterates that the jets could be spacecraft thrusters and has floated a much larger size estimate, a view other astronomers dispute as inconsistent with common comet behavior.
  • The New York Post reports NASA is expected to release Mars Reconnaissance Orbiter HiRISE images next week after a shutdown delay, which could sharpen constraints on the nucleus.
  • The object has reappeared from behind the Sun and, according to Futurism, is expected to make its closest pass by Earth just before Christmas on its outbound path.
  • The Post also reports the object is headed toward Jupiter and may be observed by NASA’s Juno and ESA’s JUICE spacecraft as it departs the inner solar system.
