The global system governing nuclear weapons is not anchored in a single treaty but rather a web of agreements, arms-control arrangements, and regional initiatives, each designed to address different facets of nuclear security. While some agreements restrict which nations can possess nuclear weapons, others focus on halting tests, limiting arsenals, or even striving to establish nuclear-weapon-free zones. As of 2025, nine countries—led by the United States and Russia—currently mainta

The Artemis II mission, a landmark achievement in human space exploration, has successfully concluded with a dramatic splashdown in the Pacific Ocean. The mission, which took four astronauts farther than any human before, traversed 4,06,778 kilometers from Earth, reaching the vicinity of the Moon. This daring journey marked humanity’s first crewed mission to the Moon since the Apollo program. The crew, consisting of Commander Reid Wiseman, Pilot Victor Glover, and Mission Speciali

  In 1945, the world was on the edge of significant change, driven by the destructive forces of war. The United States and Japan, two powerful nations, found themselves on a path of inevitable conflict, forever altering the course of history. Japan’s imperial ambitions across Asia and the Pacific created rising tensions with the U.S. and Western nations. The United States had long condemned Japan’s expansion, particularly its invasion of China and occupation of Fren

A nuclear weapon explosion unleashes an overwhelming amount of energy through either nuclear fission or fusion, resulting in devastating consequences that can persist for decades. Upon detonation, a rapid chain reaction occurs, converting a tiny amount of mass into an enormous amount of energy, based on Einstein’s Mass–energy equivalence principle. This energy is released in multiple destructive layers, each contributing to the profound impact on the environment and living organisms

The Artemis II crew has made history by capturing breathtaking views of the far side of the Moon during a record-setting flyby. This landmark achievement in space exploration comes as part of NASA's Artemis program, which aims to return humans to the Moon and ultimately send astronauts to Mars. The crew of Artemis II, aboard the Orion spacecraft, achieved a rare and remarkable perspective of the lunar surface, providing viewers with never-before-seen imagery of the Moon’s far side.

On April 7, 2026, the crew set a new record for the farthest human spaceflight, surpassing the distance achieved during the Apollo 13 mission in 1970. During the lunar flyby, astronauts Reid Wiseman,

NASA’s Artemis 2 mission is advancing as the agency prepares to send astronauts on a historic journey around the moon, marking the first crewed lunar mission in decades. The mission represents a major milestone in the broader Artemis program, which aims to establish a sustained human presence on the lunar surface and eventually support deeper space exploration. The Artemis 2 crew is expected to travel aboard the Orion spacecraf

A warship lost during the Battle of Copenhagen in 1801 has been discovered off the coast of Denmark, marking a significant archaeological breakthrough more than two centuries after it sank. Maritime archaeologists confirmed the find on Thursday, April 3, 2026, following months of underwater excavation in Copenhagen Harbor. The vessel, identified as the Dannebroge, was located about 15 meters below the seabed during surveys conducted ahead of a planned infrastructure project. The shi

The world is once again looking at the Moon with excitement. After more than 50 years, humans are preparing to travel around the Moon again, and the NASA Artemis II mission is ready to make history. This mission will send four astronauts into space, taking them around the Moon and back to Earth. It is not just a space journey—it is the beginning of a new era of space exploration. What is Artemis II Mission?

A decommissioned NASA satellite that once helped scientists understand how Earth’s magnetic field protects the planet from harmful cosmic radiation is expected to reenter Earth’s atmosphere on Tuesday evening. According to NASA, the spacecraft known as Van Allen Probe A could make atmospheric reentry around 7:45 p.m. Eastern Time, though officials note that predicting the exact moment remains difficult. Space agencies say the timing of the event carries uncertainty, with the act

India is rapidly advancing its deep sea exploration ambitions as the Samudrayaan mission prepares for its first manned trial dive in May 2026. The National Institute of Ocean Technology in Chennai is currently completing final integration work on the Matsya 6000 submersible, a 25 tonne vehicle designed to carry three aquanauts into the deep ocean. The upcoming dive, planned at a depth of 500 meters, is considered a critical milestone toward India’s long term goal of reaching 6,000 meters un

The Indian Space Research Organisation experienced a tense morning on Tuesday after the Polar Satellite Launch Vehicle C62 lifted off from the Satish Dhawan Space Centre in Sriharikota at 10.18 am carrying a total of 16 satellites. The mission initially appeared to progress as planned, with scientists closely monitoring each phase of the flight. However, around 30 minutes after liftoff, ISRO confirmed that the mission had encountered an anomaly during the third stage of the launch sequence, r
