A newly identified asteroid, 2024 YR4, has drawn attention from astronomers and space agencies as calculations reveal a small but notable chance of colliding with Earth in 2032. Initially, the probability of impact was placed at 1.2%, but with updated observational data, the likelihood has increased to 2.3% (approximately 1 in 43). While this still represents a relatively low risk, the potential threat is significant enough for experts to continue closely t

Sunita Williams Breaks Spacewalking Record While Stranded on the ISS NASA astronaut Sunita "Suni" Williams has set a new record for total spacewalking time by a female astronaut, surpassing Peggy Whitson's previous record of 60 hours and 21 minutes. Williams achieved this milestone during her ninth spacewalk on January 30, 2025, as she worked outside the International Space Station

Overview of ISRO's START 2025 Program: ISRO Chairman S Somanath delivered a keynote speech at the launch of the Space Science and Technology Awareness Training (START 2025) program, emphasizing the role of space science beyond the excitement of becoming astronomers. He explained that space science involves rigorous and time-consuming work that requires years of persistent effort and expertise. He shared that this year’s program will involve 20,000 students from more than 560

Renowned rocket and spacecraft propulsion expert V. Narayanan is set to take over as the next Chairman of the Indian Space Research Organisation (ISRO), succeeding S. Somanath. His appointment comes at a pivotal time for India's space sector, which is undergoing significant reforms, with numerous ambitious projects on the horizon, including the Gaganyaan human spaceflight, Chandrayaan-4, and the development of India’s own space station.

On December 13, 2024, the United States and China signed a bilateral science and technology agreement, revising a 45-year-old pact. However, this new agreement limits research collaboration and narrows the scope of topics allowed for joint study, reflecting heightened concerns over international research security. Governments worldwide, including the U.S., European Union, Canada, and Japan, have introduced stricter measures to safeguard sensitive scientific data from foreign interference, esp

The number of sunrises seen by the crew aboard the International Space Station (ISS) is determined by the station’s rapid orbiting of Earth. As of January 1, 2025, U.S. astronaut Sunita Williams, currently stationed on the ISS, is set to witness 16 sunrises as the world enters the New Year. Williams, the commander of the “Expedition 72” mission, is joined by her fellow flight engineers: Alexey Ovchini

India is gearing up to launch a massive American communications satellite that will enable phone calls using direct connectivity from space. This innovative approach to satellite telephony is a first for India, which has previously only launched small satellites made by American entities.   The satellite, operated by AST SpaceMobile, a Texas-based company, will allow users to make voice calls u

Sriharikota (Andhra Pradesh): ISRO is preparing for a major milestone as it plans the 100th launch from the Sriharikota spaceport, scheduled for January. This milestone will be achieved with a Geosynchronous Launch Vehicle (GSLV) mission, according to ISRO Chairman S. Somanath. The 99th launch from Sriharikota took place on Monday, with the successful PSLV-C60

What Is a Black Moon and How to Experience This Rare Phenomenon? Skywatchers are in for a treat as 2024 concludes with a rare astronomical event called the "black moon." This fascinating term refers to the second new moon occurring within a single calendar month. While not officially recognized in astronomy, the phenomenon has gained popularity among amateur astronomers and stargazers over the years. According to the US Naval Observatory, the black moon will oc

NASA's Parker Solar Probe is gearing up for a record-breaking approach to the sun's surface on Christmas Eve. The spacecraft will come within 3.8 million miles of the sun, making it the closest any human-made object has ever come to a star.   Traveling at an incredible 430,000 mph, the Parker Solar Probe will make its closest approach of all 24 scheduled orbits around the sun. This hist

A catastrophic fire erupted at Escientia Advanced Sciences Private Ltd. in the Special Economic Zone at Atchutapuram, Anakapalli, Andhra Pradesh, resulting in the tragic deaths of at least 18 workers and leaving 20 others seriously injured. The blaze, reportedly triggered by a reactor explosion, has shocked the region and prompted an immediate response from the Andhra Pradesh government. Chief Minister

Neuroscience and Brain-Computer Interfaces: Bridging Minds and Machines Neuroscience, the study of the nervous system, is a rapidly advancing field that seeks to understand the complex mechanisms underlying brain function, behavior, and cognition. One of the most exciting and transformative applications of neuroscience is the development of brain-computer interfaces (BCIs), which allow direct communication between the brain and external de
