    On June 13, 1983, the Pioneer 10 spacecraft became the first human-made object to leave the solar system. Launched on March 2, 1972, Pioneer 10 was designed to study Jupiter and the outer regions of the solar system.

    After successfully completing its primary mission of exploring Jupiter in 1973, Pioneer 10 continued its journey toward the edge of the solar system. As it traveled farther away from Earth, the spacecraft's signal grew weaker, but it continued to send back valuable data about the solar wind, cosmic rays, and other interstellar phenomena.

    On June 13, 1983, Pioneer 10 crossed the orbit of Neptune, which was then considered the outermost planet in the solar system (Pluto was reclassified as a dwarf planet in 2006). At this point, the spacecraft was approximately 3.7 billion miles (6 billion kilometers) from Earth, making it the most distant human-made object in space.

    Pioneer 10 continued to communicate with Earth until January 23, 2003, when its signal was last detected. By that time, the spacecraft was over 7.5 billion miles (12 billion kilometers) from Earth. Scientists believe that Pioneer 10 will continue to drift through interstellar space, carrying a golden plaque that contains information about Earth and humanity, serving as a cosmic message in a bottle for any potential extraterrestrial civilizations that might encounter it in the distant future.

    The success of Pioneer 10 paved the way for future missions to explore the outer reaches of the solar system and beyond, including the Voyager missions and the New Horizons spacecraft that visited Pluto in 2015.

    On June 12, 1981, a groundbreaking discovery was made that would change the course of medical history. On this day, the Centers for Disease Control and Prevention (CDC) published a report describing a rare lung infection in five previously healthy young gay men in Los Angeles. This report marked the first official recognition of what would later become known as Acquired Immunodeficiency Syndrome (AIDS), caused by the Human Immunodeficiency Virus (HIV).

    The report, titled "Pneumocystis Pneumonia—Los Angeles," detailed the cases of these young men who had all been diagnosed with a rare lung infection called Pneumocystis carinii pneumonia (PCP). This type of pneumonia was unusual because it typically affected people with severely compromised immune systems, such as cancer patients undergoing chemotherapy. The report also noted that the men had other unusual infections, suggesting that their immune systems were not functioning properly.

    This report was the first official documentation of what would become one of the most significant global health crises of the 20th century. It marked the beginning of a long and difficult journey to understand, treat, and prevent HIV/AIDS.

    In the years that followed, researchers worked tirelessly to identify the cause of AIDS and develop treatments. In 1983, scientists isolated the virus that causes AIDS, and in 1985, the first commercial blood test for HIV became available. This allowed for wider testing and helped to slow the spread of the virus.

    However, the early years of the AIDS epidemic were marked by fear, stigma, and discrimination. Many people with AIDS faced rejection from their families, friends, and communities. There was also a lack of government response and funding for research and treatment.

    Despite these challenges, activists and advocates fought tirelessly to raise awareness, combat discrimination, and push for increased research and access to treatment. In 1987, the first antiretroviral drug for treating HIV was approved, and over time, more effective treatments were developed.

    Today, while there is still no cure for HIV/AIDS, advances in treatment have made it possible for people with HIV to live long and healthy lives. Prevention efforts, including education and the use of pre-exposure prophylaxis (PrEP), have helped to reduce the spread of the virus.

    The CDC's report on June 12, 1981, marked a pivotal moment in the history of medicine and public health. It was the first step in recognizing and confronting a global health crisis that would go on to claim millions of lives and change the world forever.

    On June 11 in Science History, a significant event took place in 1955 when a group of scientists, led by physicist Hugh Bradner, tested the first wetsuit at the University of California, Berkeley. This innovative invention would go on to revolutionize underwater exploration and water sports.

    Hugh Bradner, who was working at the UC Berkeley Physics Department, had been tasked by the U.S. Navy to develop a suit that could protect divers from cold water during underwater missions. Bradner's design was inspired by the fur of otters and seals, which trap a thin layer of water between their skin and fur to keep them warm.

    Bradner's wetsuit was made from neoprene, a synthetic rubber material that provided insulation and flexibility. The suit was designed to allow a small amount of water to enter between the suit and the diver's skin. The water would then be warmed by the diver's body heat, creating an insulating layer to protect against cold temperatures.

    On that day in 1955, Bradner and his team tested the wetsuit in the cold waters off the coast of California. The results were remarkable – divers were able to stay in the water for extended periods without experiencing the debilitating effects of hypothermia.

    The invention of the wetsuit opened up new possibilities for underwater exploration, marine biology research, and water sports. Today, wetsuits are used by millions of people worldwide, from surfers and swimmers to Navy SEALs and marine biologists.

    Bradner's groundbreaking invention is a testament to the power of scientific curiosity and innovation. By drawing inspiration from nature and applying scientific principles, Bradner and his team created a tool that has had a lasting impact on our understanding and exploration of the underwater world.
