July 16, 2020 marks the 75th anniversary of the first nuclear detonation, the culminating efforts of the four-year-long Manhattan Project. This test took place on what is now known as the White Sands Missile Range near Socorro, New Mexico in the sweltering summer of 1945. In observance of that moment in history, here’s a peek at some photos from the time period and today.

J. Robert Oppenheimer, physicist and "father of the atomic bomb," later described watching the explosion as such:

"We knew the world would not be the same. A few people laughed, a few people cried. Most people were silent. I remembered the line from the Hindu scripture, the Bhagavad Gita; Vishnu is trying to persuade the Prince that he should do his duty and, to impress him, takes on his multi-armed form and says, 'Now I am become Death, the destroyer of worlds.' I suppose we all thought that, one way or another."
At 0.025 seconds, the fireball appeared more translucent.

Brigadier General Thomas F. Farrell, who served as Chief of Field Operations of the Manhattan Project, described it as:

"The lighting effects beggared description. The whole country was lighted by a searing light with the intensity many times that of the midday sun. It was golden, purple, violet, gray, and blue. It lighted every peak, crevasse and ridge of the nearby mountain range with a clarity and beauty that cannot be described but must be seen to be."

Green, glassy, and radioactive, it is composed of quartz and sand that melted and fused during the blast.

75 years later, there is still some level of radioactivity in the area with the levels at ground zero approximately 10 times higher than its surrounding areas.
