Hubble Captures Stunning Image of Speedy Interstellar Comet 3I/ATLAS
  • NASA’s Hubble Space Telescope captured a new, deeper image of interstellar comet 3I/ATLAS on November 30 using the Wide Field Camera 3, while the object speeds through the solar system at remarkable velocity.

  • The latest Hubble image places 3I/ATLAS about 178 million miles from Earth, with the comet appearing near the image center as background stars streak due to its rapid motion.

  • Officials note that the interstellar visitor will eventually vanish back into interstellar space as it continues its journey beyond the solar system.

  • Its extreme speed suggests it has undergone multiple gravitational slingshots around stars and planets, implying it is likely billions of years old and perhaps formed far in the galaxy.

  • 3I/ATLAS is on a trajectory that will skim the inner solar system and then depart outward; a future return, if any, would occur thousands of years from now.

  • Ongoing observations of 3I/ATLAS continue to yield valuable insights into how interstellar objects travel through and interact with our solar system.

  • 3I/ATLAS was first detected in the summer of 2025 by the ATLAS survey in Chile and confirmed as interstellar due to its high velocity and hyperbolic path.

  • The Wide Field Camera 3 provides a panchromatic view, enhancing the study of fast-moving objects, distant galaxies, and exoplanets as researchers track such phenomena.

  • The effort involves collaboration among NASA, ESA, and STScI, with scientists like D. Jewitt and M.-T. Hui contributing to data interpretation from Hubble and other observatories.

  • 3I/ATLAS is the fastest interstellar object on record, traveling around 130,000 miles per hour and first detected in July, with NASA and astronomers continuing to study it.

  • The comet follows a hyperbolic trajectory, meaning it is not gravitationally bound to the Sun and poses no threat to Earth.

  • Current observations place 3I/ATLAS about 178 million miles from Earth, with officials estimating it will not come closer than roughly 170 million miles.

  • Researchers and multiple NASA missions plan to continue observing 3I/ATLAS for several more months to deepen our understanding of this interstellar visitor.

  • In the latest image, 3I/ATLAS sits at the center while distant stars appear blurred, illustrating the comet’s rapid movement across the field.

  • Hubble imagery also shows background stars streaking as the comet sweeps by, highlighting its swift relative motion.
