An interstellar comet named 3I/ATLAS, originating from outside our solar system, is passing through. NASA recently released new images of the comet, which is being studied by astronomers worldwide.

The images were captured by the High Resolution Imaging Science Experiment (HiRISE) aboard the Mars Reconnaissance Orbiter (MRO) on Oct. 3, when the comet passed within about 18 million miles of Mars.
