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.
