Scientists literally brought out the big gun to study the origins of water

Did planets like Earth, Mars, Venus, and Mercury form dry out of the dust and heat of the inner solar system, only to be drenched in water delivered from ice-laden comets later on? Or did drier asteroids and asteroid collisions bring the wet stuff?

To really understand how this water delivery system works, you need to watch it happen. But meteorite strikes are notoriously unpredictable, so researchers decided to create their own with the help of a super-sized gun at NASA’s Ames Research Center.

African-American Civil War Veterans Created Their Own Town

After the Civil War, 18 veterans of the United States Colored Troops returned to Talbot County, on Maryland’s Eastern Shore, where their families had toiled for generations. But this time, they had a chance to create something their ancestors had been denied: a village of their own, where everyone was free.

Journey to the Roof of Africa

Looming high among the volcanic outriders of the Great Rift Valley in northern Ethiopia, is nature with a serious case of gigantism: a basalt escarpment 40 kilometers long, staggered between altitudes of 11,000 and 15,000 feet, populated with super-sized plants and armies of monkeys 500-strong. In 1978, UNESCO dubbed it “one of the most spectacular landscapes in the world,” and consecrated the Simien Mountains National Park in its very first batch of World Heritage Sites, alongside Yellowstone and the Galapagos Islands.

Rare Metals on Mars And Earth Implicate Colossal Impacts - Astrobiology

New research has revealed that a giant impact on Mars more than four billion years ago would explain the unusual amount of “iron loving” elements in the Red Planet.

Planets form as small dust grains stick together and agglomerate with other grains, leading to bigger bodies termed “planetesimals.” These planetesimals continue to collide with each other and are either ejected from the Solar System, gobbled up by the Sun, or form a planet. This is not the end of the story, as planets continue to accrete material well after they have formed. This process is known as late accretion, and it occurs as leftover fragments of planet formation rain down on the young planets.

Zoot Suit Riots

The Zoot Suit Riots were a series of conflicts in June 1943 in Los Angeles, California, United States, which pitted European Americans servicemen stationed in Southern California against Mexican American youths and other minorities who were residents of the city.

European American servicemen and White European immigrant civilians attacked and stripped children, teens, and youths who wore zoot suits, ostensibly because they considered the outfits to be unpatriotic during World War II, as they had a lot of fabric. Rationing of fabric was required at the time for the war effort. While most of the violence was directed toward Mexican American youth, young African American and Filipino Americans who were wearing zoot suits were also attacked.

The Zoot Suit Riots were related to fears and hostilities aroused by the coverage of the Sleepy Lagoon murder trial, following the killing of a young Latino man in a barrio near Los Angeles. The riot appeared to trigger similar attacks that year by European Americans against Latinos in Chicago, San Diego, Oakland, Evansville, Philadelphia, and New York City.

  • Did the cities that banned the zoot suit solve the underlying problems? 
  • What other fashions have caused social ruckus?
