What killed the Dinosaurs?

Dinosaurs roamed the Earth for 135 million years. Filling every ecological niche, from the oceans, forests and plains; even the skies. Then, 66 million years ago, something terrible happened. In a geological instant, 75% of the plants and animals on Earth went extinct. And all of the land dinosaurs were wiped off the Earth forever.

Remembering the Great Meteor Procession of 1860

July 20th is a red letter date in space history. Apollo 11, the first crewed landing on the Moon, took place on this day in 1969. Viking 1 also made the first successful landing on Mars, seven years later to the day in 1976.
A remarkable astronomical event also occurred over the northeastern United States 153 years ago today on the night of July 20th, known as the Great Meteor Procession of 1860. And with it came a mystery of poetry, art and astronomy that was only recently solved in 2010.

The great North American Locust plague

Locusts are the swarming phase of certain species of short-horned grasshoppers in the family Acrididae. These are species that can breed rapidly under suitable conditions and subsequently become gregarious and migratory when their populations become dense enough. They form bands as nymphs and swarms as adults. Both the bands and the swarms are nomadic and rapidly strip fields and greatly damage crops. The adults are powerful fliers; they can travel great distances, consuming practically all green material wherever the swarm settles.
