Black holes are astronomical objects whose gravitational fields become so intense that light cannot escape after crossing a boundary known as the event horizon. Although black holes do not emit light from within this boundary, the matter surrounding them can become extremely hot and produce powerful electromagnetic radiation. Astronomers study this radiation to investigate physical processes occurring in regions where gravity strongly influences the movement of matter.

ISRO launched the SPADEX mission on 30 December 2024 aboard the Polar Satellite Launch Vehicle PSLV-C60 from the Satish Dhawan Space Centre at Sriharikota. The launch vehicle placed the two spacecraft into a circular orbit approximately 470 kilometres above Earth, with an orbital inclination of 55 degrees.

Centaurus X-3 is a high-mass X-ray binary system located in the constellation Centaurus. It consists of a neutron star orbiting a massive companion star whose mass exceeds ten times that of the Sun. The system has attracted considerable scientific attention because of its intense X-ray emissions and its importance in the early development of X-ray astronomy.

The Drishti Transmissometer, developed by Bengaluru-based CSIR-National Aerospace Laboratories, is an important achievement in India’s indigenous aviation technology programme. The system measures runway visibility and provides information that helps airport authorities, air traffic controllers and pilots make operational decisions during fog, rain and other conditions that restrict visibility.

In the era of intense planetary exploration, identifying terrestrial analogue sites has become a pressing requirement, as recent studies demonstrate that orbital data alone cannot fully characterize Martian minerals. High-precision, state-of-the-art analytical tools are essential for these investigations.

Scientists from Birbal Sahni Institute of Palaeosciences (BSIP), an autonomous institute of the Department of Science and Technology (DST), reconstructed 4600 years of climate and environmental history by tracing palaeo-environmental conditions using proxies such as stable isotopes, vegetation changes as well as archaeological and sedimentary records from Karela Lake, an oxbow lake in Hulas Khera near Lucknow in the Central Ganga Plain.
