Alas, scientists are not convinced. <\/p>\n<p>Unfortunately, the ongoing U.S. government shutdown means that NASA\u2019s workforce is currently at home, apparently unable to put out a statement about the object. <\/p>\n<p>However, NASA had been closely following the interstellar comet 3I\/ATLAS \u2014 only the third known object from outside the solar system to be discovered \u2014 and had previously said it plans to use Perseverance to monitor it. <\/p>\n<p>Furthermore, the date of the photo (October 4) coincides with when 3I\/ATLAS was expected to make its closest pass to Mars. <\/p>\n<p> <a href=\"https:\/\/petapixel.com\/2025\/10\/07\/perseverance-rover-captures-cylindrical-object-flying-close-to-mars\/mars_perseverance_nrf_1643_0812830488_112eby_n0790870ncam00234_09_0llj\/\" rel=\"attachment wp-att-819161 noopener\" data-wpel-link=\"internal\" target=\"_blank\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.europesays.com\/uk\/wp-content\/uploads\/2025\/10\/Mars_Perseverance_NRF_1643_0812830488_112EBY_N0790870NCAM00234_09_0LLJ-800x606.jpeg\" alt=\"A grainy, noisy image with a mostly gray background and a single short white streak near the center, resembling a small bright light or object amidst heavy visual static.\" width=\"800\" height=\"606\" class=\"size-large wp-image-819161\"  \/><\/a>NASA\u2019s Mars Perseverance rover acquired this image using its onboard Right Navigation Camera (Navcam). | NASA\/JPL-Caltech<\/p>\n<p>In the absence of any information from NASA, Harvard astronomer Avi Loeb wrote a <a href=\"https:\/\/avi-loeb.medium.com\/interpretation-of-the-stripe-in-the-new-image-of-3i-atlas-from-the-perseverance-rover-camera-7c5332c60ff1\" data-wpel-link=\"external\" target=\"_blank\" rel=\"follow external noopener\">blog post<\/a> explaining that at the time the two photos were taken, 3I\/ATLAS was roughly 38 million kilometers (23.6 million miles) from Mars. <\/p>\n<p>Loeb did some rough calculations and estimates the cylindrical shape in the sky is approximately 31,000 miles long. But he says that 3I\/ATLAS isn\u2019t that big; instead the comet was elongated because of the camera\u2019s \u201clong integration time.\u201d <\/p>\n<p>\u201cIn conclusion, the stripe in the Navcam image must have resulted from stacking hundreds of Navcam images over a total time interval of about ten minutes. 3I\/ATLAS would have looked like a circular spot for an individual snapshot, which has a maximum exposure time of 3.28 seconds for Navcam,\u201d Loeb writes. <\/p>\n<p>\u201cIf the Navcam images represent single snapshots with an exposure time below 3.28 seconds, then the brightness and angular length of the observed source imply that it is not 3I\/ATLAS. In that case, the source might be much closer to the camera \u2014 capable of being smeared into an elongated image with a smaller spatial size and a smaller speed.\u201d<\/p>\n<p><a href=\"https:\/\/futurism.com\/space\/nasa-mars-rover-photo-interstellar-object\" data-wpel-link=\"external\" target=\"_blank\" rel=\"follow external noopener\">Futurism notes<\/a> that there should be confirmation soon, as NASA\u2019s Mars Reconnaissance Orbiter also got an image of the comet, but that is still unreleased. <\/p>\n<p> <a href=\"https:\/\/petapixel.com\/2025\/09\/04\/youve-never-seen-an-interstellar-comet-look-this-awesome\/growing-tail-of-interstellar-comet-3i-atlas-3\/\" rel=\"attachment wp-att-813562 noopener\" data-wpel-link=\"internal\" target=\"_blank\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.europesays.com\/uk\/wp-content\/uploads\/2025\/10\/noirlab-gemini-south-comet-3i-atlas-featured-800x420.jpg\" alt=\"A comet with a bright core and faint tail moves through space, surrounded by colorful, streaked star trails in red, green, and blue on a dark background.\" width=\"800\" height=\"420\" class=\"size-large wp-image-813562\"  \/><\/a>International Gemini Observatory\/NOIRLab\/NSF\/AURA\/Shadow the Scientist<br \/>Image Processing: J.
