NASA's Dawn spacecraft, which orbited asteroid Vesta in 2012, captured images of enigmatic gullies on the asteroid's surface, prompting scientists to investigate their origins. A recent study published in the Planetary Science Journal explores the possibility that these gullies were formed by brief liquid flows involving briny water. Researchers at NASA's Jet Propulsion Laboratory (JPL) simulated conditions similar to Vesta's surface using the Dirty Under-vacuum Simul

Om Prakash Chautala, a five-time Chief Minister of Haryana and a prominent figure in Indian politics, has passed away at 89 following a cardiac arrest at his residence in Gurgaon. Born on January 1, 1935, in Sirsa, Haryana, Chautala’s political career spanned several decades. He first became Chief Minister in 1989, but his tenure was marked by short stints due to political instability. His third term in 1991 was also brief, as President's rule was imposed within two weeks. However,

NASA has announced that astronauts Butch Wilmore and Sunita Williams, who have been stranded on the International Space Station (ISS) since June, will remain in space at least until late March 2025. Originally, they were meant to spend just eight days aboard the ISS, but due to issues with Boeing's Starliner spacecraft's propulsion system, their mission was altered. After Starliner faced difficulties, NASA decided to send the astronauts back with the Crew-9 mission, which arrived in S

The Indian rupee opened at 84.83 against the US dollar on Monday, a depreciation of 4 paise compared to the previous close of 84.79. The decline in the rupee is largely attributed to the uncertainty following the announcement of a leadership transition at the Reserve Bank of India (RBI). Shaktikanta Das will be succeeded by Sanjay Malhotra, sparking initial concerns in the market. However, markets quickly adjusted to the news, with experts noting that the RBI is closely monitoring banking sys

NASA is pioneering new frontiers in space exploration with the development of tiny underwater robots through the Sensing With Independent Micro-swimmers (SWIM) project. These innovative robots are designed to explore extraterrestrial oceans, beginning with the icy waters beneath Jupiter's moon, Europa. SWIM robots were recently tested in a Caltech swimming pool, demonstrating their ability to navigate autonomously. The SWIM project is an integral part of NASA's broader strat

A groundbreaking study using data from NASA and German satellites has revealed a concerning and persistent decline in Earth's freshwater reserves since May 2014. The findings, published in Surveys in Geophysics, highlight a significant reduction in the amount of freshwater stored on land, including in lakes, rivers, and underground aquifers. This shift, tracked by the Gravity Recovery and Climate Experiment (GRACE) mission, suggests a transition towards drier conditions across co

A powerful solar flare, classified as an X2.3 flare, disrupted radio communications over parts of the Atlantic Ocean, South America, and Africa on November 6, 2024. The event, which took place at 8:40 am ET, caused a shortwave radio blackout, highlighting the significant impact solar flares can have on global communications. NASA’s Solar Dynamics Observatory (SDO), which constantly monitors solar activity, captured images of the flare. Solar flares are intense bursts of energy

That Andhra Pradesh state IT and education minister Nara Lokesh is gradually emerging as the heir apparent of his father and chief minister N Chandrababu Naidu is being established gradually in the TDP and also the government. The way the TDP ranks have been calling Lokesh the future chief minister of Andhra Pradesh on social media and the state government carrying his picture on the front page advertisements of the official programmes along with his father clearly indicated that Lokesh is em

NASA's Parker Solar Probe is about to make its final gravity assist flyby of Venus on November 6, 2024, a key maneuver that will adjust its trajectory as it sets course for the closest-ever approach to the Sun. After this flyby, Parker will come within just 3.86 million miles of the Sun on December 24, 2024, breaking records and allowing scientists to study the Sun’s outer atmosphere (the corona) and solar wind at unprecedented proximity. The Parker Solar Probe, which laun

For astronauts aboard the International Space Station (ISS), the beauty of sunrise and sunset is not a once-a-day event; instead, they experience this breathtaking spectacle up to 16 times in a single Earth day. NASA astronaut Sunita Williams, currently on the ISS, knows this phenomenon well. During a 2013 event at the University of Gujarat, she reflected on her unique experience of witnessing 16 sunrises and sunsets while orbiting the Earth in a fast-moving shuttle. Due to delays i

NASA astronaut Sunita Williams is making history as she prepares to vote in the upcoming U.S. Presidential election from the International Space Station (ISS), where she is currently serving as commander. Williams will cast her ballot approximately 400 kilometers above Earth, joining a select group of astronauts who have exercised their right to vote from space. The ability for astronauts to vote while in orbit has been available since 1997 when Texas passed legislation allowing NAS

NASA Astronaut Sunita Williams Sends Diwali Wishes from Space NASA astronaut Sunita Williams, who has spent nearly five months aboard the International Space Station (ISS), extended heartfelt Diwali greetings to those celebrating in the United States and worldwide. In a video message recorded from 260 miles above Earth, Williams, of Indian heritage, shared her unique perspective on the festival from space. She reflected on her father’s dedication to

The countdown has officially begun for NASA's Europa Clipper mission, now scheduled to launch on Monday after a delay caused by Hurricane Milton, which impacted Florida last week. The storm resulted in damage to parts of NASA's Kennedy Space Center, but preparations have resumed for this ambitious mission. The Europa Clipper spacecraft will embark on an extraordinary journey, traveling 1.8 billion miles (2.9 billion km) to reach Jupiter, with an anticipated arrival in April

Astronomers have made a groundbreaking discovery involving a massive black hole that is currently disrupting two celestial objects, one of which is a star. Utilizing NASA's observatories, including Chandra, NICER, and Hubble, alongside India’s AstroSat, researchers have gained new insights into the behavior of stellar debris surrounding supermassive black holes. In 2019, astronomers observed a star that ventured too close to a supermassive black hole, resulting in a tidal

In a significant transition for the Tata Group, Noel Tata has been appointed Chairman of Tata Trusts, succeeding his half-brother Ratan Tata, who passed away at the age of 86 in a Mumbai hospital. Ratan Tata's death marks the end of an era for Indian business, where he transformed the Tata Group into a global powerhouse, reshaping the country’s industrial landscape. Noel Tata has been an influential figure within the Tata Group since he joined in the early 2000s. His appoi

Indian-origin NASA astronaut Sunita Williams has made history once again by becoming the commander of the International Space Station (ISS). Her journey to this pivotal role began with an eight-day mission that was unexpectedly extended to over eight months due to technical issues with the Boeing Starliner spacecraft. During a formal ceremony aboard the ISS, Russian cosmonaut Oleg Kononenko handed over command to Williams, who has been working to advance scientific research and tech

NASA has made a groundbreaking discovery by capturing eerie audio waves emanating from a supermassive black hole located 250 million light-years away in the Perseus cluster of galaxies. By transposing these acoustic waves up 57 and 58 octaves, NASA made it possible for human ears to experience this haunting sound that resonates throughout the cosmos. This revelation challenges the common perception that sound cannot exist in the vacuum of space. The concept of sound in space was fir
