Meteorito que Extinguió Dinosaurios | Impacto Chixculub

When a meteor enters Earth’s atmosphere, it’s traveling at tens of thousands of miles per hour. The intense speed causes the air in front of it to compress and heat up to thousands of degrees. This heat is what makes the meteor glow so brightly, creating the streak of light we call a “shooting star.” As the meteor continues its fiery descent, its outer layers vaporize and peel away in a process known as ablation. The smaller the meteor, the more likely it is to burn up completely before reaching

☄️ A 3-foot wide meteor entered the Earth’s atmosphere near the Massachusetts and New Hampshire border, says the American Meteor Society, causing the “sonic boom” that many of us felt across Greater Boston on Saturday afternoon. WBZ’s Jacob Wycoff breaks down what happened and where this meteor was spotted across the northeast. NASA also released the following statement: “Eyewitnesses in New England and NOAA’s GOES-19 satellite reported a bright fireball on Saturday, May 30, at 2:06 p.m EDT acco

On August 21, 1986, a sudden, catastrophic natural phenomenon occurred at Lake Nyos, a deep volcanic crater lake in northwestern Cameroon. Deep beneath the surface, years of volcanic activity had heavily saturated the water with a massive, highly pressurized concentration of carbon dioxide gas. A sudden underwater landslide triggered a limnic eruption, causing the lake to violently flip and release a massive gas bubble into the night air. The explosion shot a dense, heavy cloud of roughly one hu
