Dinosaurs kept warm — and accidentally survived a mass-extinction event

Paleontologists still debate a number of fundamental questions about dinosaurs. What did they look like? Did they survive freezing winters? How did some survive so many mass-extinction events that sent other large creatures into extinction?
We reported last week on a new study in the peer-reviewed journal Science Advances that offers evidence that Earth's poles froze during the age of dinosaurs — and that dinosaurs lived through the freezing winters. Now, we're sharing more details about the study and how fresh data are helping scientists answer 220 million-year-old questions about how dinosaurs survived some of the most violent cataclysms life on Earth has ever experienced.
The number of satellites in orbit is increasing and soon we will have difficulties observing the sky. Cleaning up the space debris would be like 'collecting bullets'.
