| + | == Scientists Believed This Near-Earth Object Was an Asteroid for 28 Years. They Were Wrong == | ||
| + | |||
| + | The asteroid 1998 SH2 is actually not an asteroid at all. | ||

| + | On August 28, 2025, astronomers aimed NASA’s radar system at a region of space where a near-Earth asteroid was expected to appear. Instead, the object failed to show up, leaving researchers puzzled. The unexpected no-show turned what seemed like a routine observation into a surprising case of mistaken identity. | ||
| + | |||
| + | In a study published in Nature Astronomy, a team of scientists reveals the true identity of a near-Earth object with an apparent dual personality. Scientists had been tracking the object for 28 years, assuming it might be an asteroid. Its recent deviation from its predicted path, however, suggested something unexpected is influencing the object’s motion. | ||
| + | |||
| + | Although previous observations of asteroid 1998 SH2 didn’t show obvious comet-like behavior, a more precise measurement of its position in the sky proved that its motion is irregular like that of a comet. | ||

| + | == Amateur Astronomer Discovers Ancient Meteorite Impact Using Google Maps == | ||
| + | |||
| + | Scientists confirmed that the crater dates back around 390 million years ago. | ||

| + | |||
| + | Joël Lapointe was casually browsing Google Maps, planning hiking routes for an upcoming camping trip, when he stumbled upon an unusual indentation near Marsal Lake in Quebec. As an amateur astronomer, Lapointe recognized that the large pit may be the site of a meteorite impact that left a scar on the terrain. Scientists just confirmed that he was right. | ||
| + | |||
| + | Researchers announced the existence of a large crater in the Côte-Nord region of Quebec, which dates back to around 390 million years ago, the Canadian Broadcasting Corporation (CBC) reported. Following Lapointe’s initial discovery in 2024, a team of geologists set out to examine the impact site and were able to verify that a meteorite did in fact smash into Earth at this particular point. | ||
| + | |||
| + | The team’s research will be presented at the annual congress of the Meteoritical Society, which will be held on August 9 to 14 in Frankfurt, Germany. | ||
