Astronomers from India have discovered the second farthest spiral galaxy in the depths of the universe, using the powerful James Webb Space Telescope (JWST), and have named it ‘Alaknanda’. The galaxy was an unexpected sight during a broader study of galaxy shapes in the early universe. The findings were published in Astronomy & Astrophysics in…

On December 23 Air Marshal and the Integrated Defence Staff chief Ashutosh Dixit laid out the defence establishment’s case for critical minerals. Modern defence systems, he said, rely on reliable access to these minerals and import dependence has become a strategic vulnerability because global supply chains are concentrated and exposed to export controls and geopolitics….
