Study sheds light on formation of stars, galaxies
For the first time in the world, a team of researchers at the Indian Institute of Space Science & Technology (IIST), Thiruvananthapuram, in association with international scientists, have detected and measured magnetism near an infant massive star.
The finding opens an exciting window into the understanding of how massive stars form, which later go on to shape entire galaxies. A protostar is the earliest known stage of a star that is beginning to form. The study was carried out on protostar IRAS 18162-2048, located 4,500 light years away using the National Radio Astronomy Observatory's Karl G Jansky Very Large Array in the US.
'The Astrophysical Journal Letters' brought out by the American Astronomical Society has published the study in detail. The researchers detected radio emission, with a special property known as circular polarisation near IRAS 18162-2048. The emission offers the first direct clue to the strength of magnetic fields in the immediate surroundings of a forming massive star.
While strong magnetic fields have been observed earlier in low-mass protostars that go on to form stars like the Sun, measuring such fields around massive protostars has been a tough task until now. The new data allowed researchers to infer the magnetic field near the protostar to be about 20-35 Gauss, roughly 100 times stronger than Earth's magnetic field.

NSBT and Findability Sciences launch Integrated AI Lab
Nath School of Business & Technology (NSBT) recently joined hands with AI company Findability Sciences to establish an AI Lab in Chhatrapati Sambhaji Nagar . This extends their existing partnership. Findability Sciences also has a similar partnership existing with Worcester institute, US. Students enrolled in the BCA (Artificial Intelligence & Data Science) program will gain hands-on exposure to generative AI, machine learning , and natural language processing (NLP). Anand Mahurkar, Founder & CEO, Findability Sciences, 'At Findability Sciences, our journey in Shambajinagar has always been anchored in talent, not location. Collaborating with NSBT, we're bringing world-class AI infrastructure and mentorship right here—to create an ecosystem where students solve real problems, contribute to global innovation, and uplift their own communities.' 'Quality tech education, jobs, and innovation can emerge from small towns, not just big tech hubs,' said Harsh Vardhan Jajoo, Director of NSBT.

NASA launches TRACERS twin satellites to discover the mysterious link between solar storms and tech failures
Our daily lives have increasingly become dependent upon advanced space technology satellites like GPS, communication satellites, and weather systems. So understanding the invisible forces coming from the Sun is also important. NASA has taken a major step in this direction by launching a pair of satellites known as TRACERS, which means Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites. These twin spacecraft are on a mission to better understand one of space's most energetic and mysterious processes, which is also known as magnetic reconnection. The satellites were lifted off from Vandenberg Space Force Base in California aboard a SpaceX Falcon 9 rocket at 11:13 a.m. EDT, according to NASA. This twin satellite system is set to study the constant stream of solar wind and charged particles flowing from the Sun, which interacts with Earth's magnetic shield, also known as the magnetosphere. What is magnetic reconnection When the solar wind hits this magnetic field, it can lead to magnetic reconnection, which also releases a huge amount of energy. 'As the solar wind collides with Earth's magnetic field, this interaction builds up energy that can cause the magnetic field lines to snap and explosively fling away nearby particles at high speeds. This is magnetic reconnection,' explained John Dorelli, TRACERS mission science lead at NASA's Goddard Space Flight Center. What is special about the mission? These reconnection events can cause beautiful light shows like auroras, but also cause problems for satellites, astronauts, and GPS systems. That's why TRACERS is an important mission. Over the first year alone, the mission is expected to get information on more than 3,000 such reconnection events. The twin satellites will do this while orbiting through Earth's polar cusp region, funnel-like openings in the magnetic field where the solar wind has a direct path into our atmosphere. How will the data from these satellites help the scientists The data gathered from TRACERS will help scientists improve space weather forecasting and better protect critical technology here on Earth. NASA says that once the satellites are in their sun-synchronous orbit, they'll fly in tandem, sometimes just seconds apart, to study these high-energy events in real-time. 'This is going to help us keep our way of life safe here on Earth,' said Joe Westlake, director of NASA's heliophysics division.
