How the darkness and the cold killed the (non-avian) dinosaurs

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 end of the Cretaceous”, published by the Climate scientists of Potsdam Institute for Climate Impact Research (PIK), revealed a detailed model of what happened to the atmosphere and the climate after the Chicxulub impact.

Leaving Solar System at the Speed Of Light

Our Solar system is big, and vast, despite it is really small compared to our galaxy, not to mention the complete universe. To put this into a perspective, you can think yourself as a photon emitted by the Sun. It takes about 8 minutes to reach the Earth after a photon has been emitted from the Sun’s surface. And it takes 5 hours to get out to Pluto from the Earth. The edge of the Solar System is far beyond the orbit of Pluto.

Great American Total Solar Eclipse 2017

There will be a total solar eclipse on Monday, Aug. 21, 2017, and the United States will be the best country to watch. It will be also the first total solar eclipse to go coast to coast in the U.S. in 99 years. From Oregon to South Carolina, 70-mile Moon-shadow will race across the U.S. and it will completely block out the Sun for a few minutes. It’s still more than seven months away, but hotels already are selling out as people prepare for the rare and amazing event.

Two stars may collide and light up night sky in 2022

Two stars may collide into a stunning “red nova” in 2022 (or a few months earlier, most probably between September 2021 and September 2022), and for a few weeks become one of the brightest objects in Earth’s night sky, scientists predict. When two stars merge, they increase in brightness 10 thousandfold.
