Puppis A Supernova Remnant
Driven by the explosion of a massive star, supernova remnant Puppis A is blasting into the surrounding interstellar medium about 7,000 light-years away. At that distance, this colorful telescopic field based on broadband and narrowband optical image data is about 60 light-years across. As the supernova remnant expands into its clumpy, non-uniform surroundings, shocked filaments of oxygen atoms glow in green-blue hues. Hydrogen and nitrogen are in red. Light from the initial supernova itself, triggered by the collapse of the massive star's core, would have reached Earth about 3,700 years ago. The Puppis A remnant is actually seen through outlying emission from the closer but more ancient Vela supernova remnant, near the crowded plane of our Milky Way galaxy. Still glowing across the electromagnetic spectrum Puppis A remains one of the brightest sources in the X-ray sky.

The internment of Japanese-Americans during World War II meant the removal and detainment of thousands from their homes and businesses. For the most part neighbors moved in – appropriating the abandoned homes and stores. How did the internment affect Hawaii, the state with the largest proportion of Japanese descendants?

August 28th 1963: March on Washington
On this day in 1963, the March on Washington for Jobs and Freedom took place. The march was a key moment of the Civil Rights Movement, and a triumph for the nonviolence philosophy which underpinned the movement. The march is best remembered for Martin Luther King Jr.’s famous ‘I Have a Dream’ speech, given in front of the Lincoln Memorial, which extolled King’s vision of an America free of racial discrimination. Other speakers included chairman of the Student Nonviolent Coordinating Committee John Lewis and veteran civil rights leader A. Philip Randolph. When politicians in Washington heard about the march many, including President John F. Kennedy, feared that there would be violence and rioting. The peaceful gathering of over 250,000 supporters of civil rights, with many whites in attendance as well as African-Americans, highlighted issues of racial discrimination and unequal housing and employment. The demonstration in the nation’s capital, and King’s speech in particular, spurred America into action and paved the way for the landmark 1964 Civil Rights Act and 1965 Voting Rights Act, vital tools in the fight for racial equality.

Denver was awarded the 1976 Winter Olympics, but later turned the games down because of overwhelming public opposition to the financial terms that would make the city and the state pay for everything. That plus the environmental impact made politicians and citizens rally in opposition. Voters defeated a proposal to start paying $5 million of Olympic costs by a nearly 60-40 margin. A week later, Denver relinquished its status as Olympic host.
