even if the technique for retrieving ancient DNA improves, you need to know what you’re searching for. There is no way now to search for an unknown hemorrhagic virus.
But the possibility that the Black Death could strike again should give scientists the incentive to keep trying. The similarity of the catastrophes in Athens, Constantinople and medieval Europe suggests that whatever the pathogen is, it comes out of hiding every few centuries. And the last outbreak was its fastest and most murderous. What would it do in the modern world? Maybe we should find it, before it finds us.

4.The Great Unconformity of Powell in the Grand Canyon is a regional unconformity that separates the Tonto Group from the underlying, faulted and tilted sedimentary rocks of the Grand Canyon Supergroup and vertically foliated metamorphic and igneous rocks of the Vishnu Basement Rocks.
5. They may form at all types of plate boundaries, but the thickest sedimentary rock accumulations occur at convergent plate boundaries. Metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. 6. One of the best-preserved records of these events is in the bottom of the Grand Canyon—in a package of sedimentary strata known as the Tonto Group.

The mass of the star actually determines the stage of the star after supernova. If the mass of the star is small, then it would become a very small and dwarf, cold and dead body in space. The mass of the star has to be less than that of the sun. If the mass of the star is greater than sun, then it would become a black hole. The mass of the star has to be more than 1.4 times the mass of the sun to become a black hole.

Nebula is the cloud of interstellar dust and gas that forms a star. It is collborately shaped during colliding and collapsing of the interstellar mediums this is influenced by the gravitational attraction of the atoms and particles in the entites. Hence, there are three types of nebular namely, are classical nebula, diffuse nebula, planetary nebular and supernova remnants.
