By studying lunar craters, scientists have discovered that the asteroid impacts became more frequent about 290 million years ago. So was just a matter of time for dinosaurs to becoming extinct.
What if the Earth’s history (our planet’s age is approximately 4.54 billion years), compressed into just one year, let’s say the year of 2018? @YearOnEarth just did that. At midnight on the 31st of December 2017, Chris Jennings started a little project for the incoming year: tweeting the entirety of the geological history of the […]
Around 66 million years ago, an asteroid (or a comet) with a diameter of at least 10 kilometers (6 miles) impacted a few miles from the present-day town of Chicxulub in Mexico at around 64,000 kilometers per hour (40,000 mph). The impact triggered a chain of events what it is known today as the Cretaceous-Paleogene […]
Around 66 million years ago, an asteroid or comet at least 10 kilometers (6 miles) in diameter impacted a few miles from the present-day town of Chicxulub in Mexico (hence it is dubbed as the “Chicxulub impactor”), at around 64,000 kilometers per hour (40,000 mph). The impact has created a crater (Chicxulub crater) more than […]
Hint: they are all space rocks. But, there are some differences. The biggest difference between an asteroid and a comet, for example, is what they are made of.
I stumbled upon an amazing web page showing what did ancient Earth look like. On the “Dinosaur Pictures and Facts” web page (dinosaurpictures.org), there’s also an interactive animation. On this page, you can either select the years (i.e. 600 million years ago) or jump to a particular event (i.e. first multicellular life) and see how ancient […]
On 15 February 2013, an approximately 20-meter (66 feet) meteoroid see notes 1 entered Earth’s atmosphere over Russia with a speed of 19.16 ± 0.15 kilometers per second (60,000-69,000 km/h or 40,000-42,900 mph). Its mass is estimated at 7,000 to 10,000 tons, one of the largest meteoroids entered Earth’s atmosphere in recent history. Then, at 9:20 […]
According to the scientists who drilled into the Chicxulub crater buried underneath the Yucatán Peninsula and the Gulf of Mexico, the dinosaur-killer asteroid hit the “worst possible place” (for the dinosaurs, of course). They summarized their findings so far in a BBC Two documentary titled “The Day The Dinosaurs Died“. The documentary presented by professors […]
Crocodiles are aquatic reptiles, and among the most feared carnivores on Earth, because of their size, big powerful jaws, and aggressiveness. They are so successful predators – once they were living alongside the dinosaurs. After the Chicxulub impact, which happened around 66 million years ago, the non-avian dinosaurs were gone but crocodiles were managed to survive. Here are […]
Now we have a computer simulation of how the afterward effects of famous Chicxulub asteroid (estimated to be 10 km/6.2 mi) wide) killed the non-avian dinosaurs (and also a wide range of other species). On January 13, 2017, an article titled “Baby, it’s cold outside: Climate model simulations of the effects of the asteroid impact at the […]
