NASA really wants you to know that 3I/ATLAS is an interstellar comet
In early July, astronomers worldwide began tracking 3I/ATLAS, the third confirmed interstellar visitor to our solar system, identified by the Asteroid Terrestrial-impact Last Alert System (ATLAS). This comet made its closest approach to the Sun in late October, coinciding with the U.S. government shutdown, which posed challenges for public dissemination of information. While NASA’s equipment continued to function, the shutdown meant that many scientists who could analyze and share the findings were unavailable. As a result, the scientific community eagerly awaited the opportunity to discuss the comet’s characteristics and implications.
On a recent press conference, NASA finally unveiled the insights gained from the observations of 3I/ATLAS. The comet, classified as an extrasolar object, exhibited typical cometary features such as a coma—a cloud of gas and dust—and a tail, which forms as it approaches the Sun. Despite the usual speculation from some quarters, including astronomer Avi Loeb, who has previously suggested that interstellar visitors could be spacecraft, NASA officials firmly reiterated their stance. Associate Administrator Amit Kshatrya emphasized that all evidence supports the conclusion that 3I/ATLAS is indeed a comet, dismissing any notions of it being an artificial object. This statement underscores the importance of scientific rigor in interpreting astronomical phenomena and highlights the ongoing fascination with interstellar objects as they provide valuable insights into the formation and evolution of our solar system.
As astronomers continue to study 3I/ATLAS, its journey enriches our understanding of the cosmos and reinforces the significance of collaborative efforts in space observation. The excitement surrounding such discoveries not only fuels scientific inquiry but also captivates the public’s imagination, reminding us of the vastness and mystery of the universe beyond our own solar system.
Since early July, telescopes around the world have been tracking just our third confirmed interstellar visitor, the comet 3I/ATLAS—3I, for third interstellar, and ATLAS (Asteroid Terrestrial-impact Last Alert System) for the telescope network that first spotted it. But the object’s closest approach to the Sun came in late October during the US government shutdown. So, while enough people went to work to ensure that the hardware continued to do its job, nobody was available at NASA to make the images available to the public or discuss their implications.
So today, NASA held a press conference to discuss everything that we now know about 3I/ATLAS and how NASA’s hardware contributed to that knowledge. And to say one more time that the object is a fairly typical comet and not some spaceship doing its best to appear like one.
Extrasolar comet
3I/ATLAS is an extrasolar comet and the third visitor from another star that we’ve detected. We know the comet part because it looks like one, forming a coma of gas and dust, as well as a tail as the Sun heats up its materials. That hasn’t stopped the usual suspect (

) from speculating that it might be a spacecraft, as he had for the earlier visitors. NASA doesn’t want to hear it. “This object is a comet,” said Associate Administrator Amit Kshatrya. “It looks and behaves like a comet, and all evidence points to it being a comet.”
