Today in History: August 26

Vulnerable. Reporters are vulnerable. The camera lens and a notepad do not stop bullets. One year ago today a local television news reporter and a cameraman for WDBJ7, a CBS affiliate in Virginia, were shot and killed live on the air.

The reporter was named Alison Parker; she was 24 years old and had recently gotten engaged to be married to another young WDBJ reporter. The cameraman, Adam Ward, was 27. He was engaged to be married as well and today was to be his last day at WDBJ; his fiancee was in the production studio doing her job when she watched her boyfriend get shot.

The shooter ran away and then was shot and killed by authorities himself later the same day.

Today in History: #NPS100

In popular culture, what the IAU did ten years ago today was demote Pluto (seen above) from one of the classic nine planets of the solar system, the nine whose names we all grew up memorizing and reciting, to one of several or many or thousands of “dwarf planets,” leaving us with eight planets. Schoolchildren everywhere possibly find it odd that this elicited as much controversy as it did.

The article employed in an official way a term that had been around since the early 1990s: dwarf planet. A dwarf planet is an object that is massive enough to be a ball (in scientific terms, it is a spheroid that is in hydrostatic equilibrium) and orbits the Sun, but it is not massive enough to have cleared its lane through space.
