NASA is preparing to release unprecedented, high-resolution images of the interstellar comet 3I/ATLAS, captured by the High Resolution Imaging Science Experiment (HiRISE) aboard the Mars Reconnaissance Orbiter. These images are expected to surpass the clarity of previous observations, including those from the Hubble Space Telescope in July. The release, delayed by the recent U.S. government shutdown, is now imminent.
What is 3I/ATLAS?
3I/ATLAS is only the third interstellar object ever detected within our solar system. Unlike most comets, it originates outside our cosmic neighborhood, hailing from elsewhere in the Milky Way galaxy. Its exact origin remains unclear—whether from the galaxy’s thin or thick disk—but estimates suggest it could be over 7 billion years old, making it more than 3 billion years older than our sun.
The comet is roughly 7 miles (11 kilometers) wide and travels at a staggering 130,000 mph (210,000 km/h). Having recently passed its closest point to the sun (perihelion), it will make its closest approach to Earth on December 19.
Why This Matters
The extreme age and unique composition of 3I/ATLAS, altered by billions of years of cosmic radiation, make it a subject of intense scientific interest. Studying this comet could provide valuable insights into the conditions around other stars, the early history of our galaxy, and the nature of interstellar space itself.
Despite speculation about its origins, including fringe theories of alien probes, the primary goal is to understand the comet’s composition, its journey through our solar system, and what it can tell us about the wider universe. The HiRISE images will be instrumental in this effort.
The HiRISE Camera and Image Quality
The HiRISE camera aboard the Mars Reconnaissance Orbiter has been capturing detailed images of the Martian surface since 2006. Its high resolution capabilities will allow scientists to examine 3I/ATLAS with unprecedented clarity. The expected release of these images is a significant moment for planetary science, offering a unique opportunity to study an object that has traveled from beyond our solar system.
