While experimenting with electricity, Wilhelm Röntgen discovers the X-ray.
In 1895, German physicist Wilhelm Röntgen discovers X-rays, revolutionizing medicine and physics with a new form of invisible radiation.
While experimenting with cathode rays at the University of Würzburg, Röntgen observed a glow emanating from a nearby fluorescent screen.
He realized the rays could penetrate solid objects and cast shadow images of internal structures.
Röntgen named them 'X-rays' and took the first X-ray image of his wife's hand, revealing her bones and wedding ring.
This groundbreaking discovery earned him the first Nobel Prize in Physics in 1901.
X-ray imaging transformed medical diagnostics, allowing non-invasive examination of fractures and diseases.
Röntgen's work laid the foundation for modern radiology and advanced scientific research in electromagnetic theory.

Operation Grapple X, Round C1: The United Kingdom conducts its first successful hydrogen bomb test over Kiritimati in the Pacific.
The United Kingdom carried out its first successful hydrogen bomb test over Kiritimati as part of Operation Grapple X.
On November 8, 1957, the UK detonated its first hydrogen bomb over Kiritimati (Christmas Island) in the Pacific during Operation Grapple X, Round C1. The thermonuclear device yielded several megatons, validating Britain’s entry into the nuclear hydrogen era. This achievement secured the UK’s independent deterrent status alongside the United States and the Soviet Union. Scientists and military planners analyzed the blast and radiation effects to refine future designs. The test underscored the intensifying nuclear arms race of the Cold War and Britain’s strategic ambitions. It also raised global concerns about atmospheric testing and fallout.

Manolis Andronikos, a Greek archaeologist and professor at the Aristotle University of Thessaloniki, discovers the tomb of Philip II of Macedon at Vergina.
Archaeologist Manolis Andronikos discovered the tomb of Philip II of Macedon at Vergina in 1977.
Greek archaeologist Manolis Andronikos uncovered a royal tomb at Vergina on November 8, 1977.
The site revealed the burial chamber of Philip II, father of Alexander the Great, dating to the 4th century BCE.
Among the treasures found were golden artifacts, intricate jewelry, and well-preserved human remains.
The discovery provided invaluable insights into ancient Macedonian culture, art, and funerary practices.
Andronikos’s work at Vergina transformed our understanding of Hellenistic history and archaeology.
The UNESCO-recognized site continues to be a major attraction for historians and tourists alike.

The potentially hazardous asteroid 2005 YU55 passes 0.85 lunar distances from Earth (about 324,600 kilometres or 201,700 miles), the closest known approach by an asteroid of its brightness since 2010 XC15 in 1976.
The asteroid 2005 YU55 passed within 0.85 lunar distances of Earth in 2011, marking the closest approach by such a bright object in decades.
On November 8, 2011, the near-Earth asteroid 2005 YU55 flew past our planet at a distance of approximately 324,600 kilometers (0.85 lunar distances). Measuring about 400 meters in diameter, it posed no threat but attracted scientific interest for its size and trajectory. Observatories worldwide tracked the asteroid to refine models of its orbit and physical characteristics. Radar imaging revealed details about its shape and rotation. This encounter was the closest known approach by an asteroid of similar brightness since 1976. NASA and other agencies used the opportunity to test planetary defense readiness. Public and media coverage highlighted the importance of monitoring near-Earth objects.
