The Hubble space telescope is orbiting nearly 300 miles over the Earth. It has transformed our views of the universe since its launch in 1990. It travels at an incredible speed and circles the Earth every 95 minutes simultaneously capturing breath-taking images across ultraviolet to near-infrared light. The observatory moves at a speed of about five miles (8km) per second.

Forget the Nile, the Ganges-Brahmaputra-Meghna Delta in Bangladesh and India is the world's largest. This vast region, fed by three mighty rivers, boasts rich soil and vital ecosystems. Other massive deltas like the Amazon, Indus, Mekong, and Niger also play crucial roles globally. These natural wonders shape landscapes and support life.

In 1940, a cracked silicon crystal at Bell Laboratories led Russell Ohl to discover the p-n junction, a pivotal moment for electronics. This accidental finding, revealing how semiconductors control electric current, paved the way for solar panels, transistors, and modern devices. Ohl's breakthrough remains fundamental to photovoltaic technology and countless electronic innovations today.

In 1985, scientists discovered a new form of carbon, buckminsterfullerene or C60. This molecule, shaped like a soccer ball, revealed carbon's ability to form hollow cages. The discovery opened doors to nanotechnology, influencing fields like electronics and materials science. It marked a significant shift in understanding carbon bonds and nanoparticles.

A unique, emoji-shaped Lake Rouge in Quebec vanished overnight due to a catastrophic outburst flood. This rare event, exacerbated by rapid snowmelt and past wildfires, highlights the fragility of postglacial landscapes under combined climate and human pressures. The loss deeply impacts the Waswanipi Cree, disrupting their traditional way of life.

A routine fishing trip on Lake Michigan led to an extraordinary discovery: a pre-Civil War shipwreck, the George L. Newman. Uncovered by shifting lakebed conditions, this vessel is linked to the devastating Peshtigo Fire of 1871. The find highlights how climate change is revealing lost historical secrets beneath the Great Lakes' waters.

Maria Branyas Morera, who lived to 117, defied aging expectations. Scientists discovered her internal chemistry mirrored younger individuals, with a unique microbiome and a Mediterranean diet, including daily yogurt, contributing to her remarkable health. Her lifestyle choices, devoid of smoking and alcohol, alongside constant activity and social connection, offer profound lessons for healthy aging.

A routine fishing trip in 1938 yielded an astonishing discovery: a living coelacanth, a fish thought extinct for 66 million years. This 'living fossil' challenged scientific understanding of evolution and extinction. Modern technology reveals its unique skull structure and leg-like fins, highlighting the ocean's unexplored depths and the enduring mysteries of ancient life.
