While standing on the balcony of his room at the Lorraine Motel in Memphis, TN, Dr. Martin Luther King Jr. was struck by a sniper's bullet at 6:01 p.m. on April 4, 1968. Just over an hour later, King, who had spent thirteen years of his life dedicating himself to nonviolent protest, was pronounced dead. Find out what happened that evening when Martin Luther King Jr. was assassinated.

When Neil Armstrong and Buzz Aldrin landed on the moon on July 20, 1969, they clearly made history by becoming the first human beings on the moon. What some may not know, is that when Armstrong and Aldrin left the surface of the moon, they left more than footprints behind. To put it simply, they left trash. There are currently about 100 items near Tranquillity Base, including empty food containers, a hammer, a tripod, and urine bags. These discarded items have become historical artifacts and need to be preserved.

One may first ask, who could disturb those items since they're located on the moon? Well, while NASA has no current plans to go back to the moon, private companies are hoping to do so. The next question is how do you protect something that's on international ground, over 225,000 miles away. Good question! Not easily.

On July 20, 2011, NASA created some guidelines, which included a 75-meter buffer around the Apollo 11 landing site (the first moon landing) and a 225-meter buffer around the Apollo 17 landing site (the last moon landing). The problem is that these guidelines are in no way legally binding. We can only hope that people will be respectful, follow NASA's guidelines, and not destroy these historic sites.

In a small journal, British Private Ross Taylor wrote about his experiences in WWII in short snippets, surprisingly never exceeding 140 characters each. Taylor's grandson, Chris Ayres, thought Twitter would be a great way to share Taylor's snippets. Writing from @driverross, Ayres will share Taylor's journal, which includes his experiences as a driver, being captured, and as a POW.

For more information about Taylor and his diary, please read this Telegraph article.

"To all those who have suffered as a consequence of our troubled past I extend my sincere thoughts and deep sympathy. With the benefit of historical hindsight we can all see things which we would wish had been done differently or not at all." -- Quote by Queen Elizabeth II
