NASA did not warn a real asteroid is on path to hit Earth   Published On NASA did not warn a real asteroid is on path to hit Earth (AFP) - Social media posts in Thailand have shared a claim that US space agency NASA warned an asteroid is on path to hit Earth and cannot be stopped by nuclear weapons. The claim is false: the posts misrepresented as real a NASA simulation exercise involving a fictitious asteroid. A NASA report found no known asteroids pose a significant risk to Earth over the next 100 years. The claim was shared on Facebook on May 7, 2021 alongside an image that appears to sho...

For another, Earth is an active planet. Air, water, tectonics... these are all sources of erosion, and after a few hundred thousand — or hundred million — years, craters fade away. If it weren't for those factors, the surface of the Earth would look like the surface of the Moon, saturated with craters. Nonetheless we do have some techniques to get absolute ages for craters (as opposed to relative, where you can say this crater is older than that one). But even then it can be tricky to get good numbers. Cases in point: Two of the youngest, large-ish, and well-preserved craters on Earth hav...

Science, the study also posits that the same asteroid created all of the Americas’ tropical rainforests. Around 66 million years ago, a seven-mile-wide meteor struck what is now the Yucatan Peninsula in Mexico. Named the Chicxulub impactor, the meteor produced clouds of dust and ash and catapulted fragments of rock into the sky, triggering widespread wildfires. Over time, the devastating impact drove the extinction of around 75 percent of all plant and animal species on the planet, including all terrestrial dinosaurs. The disaster also drastically changed the environment across th...

The material collected was found on Walnumfjellet, a peak in the Sør Rondane mountain range on the coast of Antarctica, about 4,000 km south of South Africa. This range of peaks reaches roughly 3,000 meters high, and the summits ice-free. Dating techniques show that the area the material came from has been exposed for at least 870,000 years.

According to new research, there is finally solid proof that an asteroid did in fact kill the dinosaurs around 66 million years ago. While the most talked about theory was that an asteroid killed them, there have been other hypotheses such as volcanic eruptions or other global catastrophes. Back in the 1980s, researchers discovered asteroid dust in the geological layer from the time of the dinosaur extinction. Then in the 1990s, experts confirmed that the Chicxulub impact crater was the same age as the geological rock layer. And now, it has been confirmed that asteroid dust has been found ins...
