In December 2015, representatives from nearly every nation on Earth adopted the Paris Agreement, a landmark accord committing the world to work together in addressing climate change and building a more sustainable future. The agreement was celebrated as a rare and hopeful moment of global cooperation.
Earlier that year, NASA's New Horizons spacecraft completed its historic flyby of Pluto, sending back the first close-up images of the distant dwarf planet after a journey of nearly a decade. It was a moment that captured public imagination about the far reaches of our solar system.
The year also brought a milestone for equality when the United States Supreme Court recognized same-sex marriage nationwide, a decision celebrated by many as a significant step forward for civil rights. Moviegoers returned to theaters in record numbers for "Star Wars: The Force Awakens," while animated favorite "Inside Out" charmed audiences of all ages.
Looking back, 2015 will be remembered as a year when nations, scientists, and communities alike chose cooperation and hope in shaping a better shared future.
