New research challenges existing theories of planet formation. Observations of exoplanet PDS 70b reveal its atmosphere contains less carbon and oxygen than expected, based on its surrounding disk. Two hypotheses are proposed: PDS 70b incorporated solid materials containing carbon and oxygen; or the disk recently became carbon-enriched. Further research is needed to determine which is correct.
Scientists propose a groundbreaking theory: fast radio bursts (FRBs), powerful cosmic blasts of energy, may originate from asteroids colliding with neutron stars. This collision releases unimaginable energy, potentially solving the long-standing mystery surrounding these enigmatic phenomena. Learn about the science behind this revolutionary discovery.
From theoretical concept to confirmed cosmic reality, black holes have captivated scientists and the public alike. This article explores the fascinating history of black hole discovery, their mind-bending properties, and invites you to test your knowledge with a fun quiz!
The James Webb Space Telescope (JWST) has unearthed a peculiar galaxy, JADES-GS+53.18343−27.79097, existing just 700 million years after the Big Bang. This galaxy exhibits an unconventional growth pattern, forming stars faster on its outskirts than in its dense core, defying the traditional understanding of galaxy development. This discovery, detailed in Nature Astronomy, confirms theoretical models predicting the existence of such ‘inside-out’ galaxies during the early universe, opening a window into the mysteries of cosmic evolution.

The James Webb Space Telescope has turned its powerful gaze toward the Milky Way’s extreme outer edge, revealing stunning details of star-forming regions and the chaotic behavior of nascent stars. The observations highlight the unique characteristics of these distant regions, offering new insights into the galaxy’s early history and the diverse processes of star formation.
Indian students achieved remarkable success at the 17th International Olympiad on Astronomy and Astrophysics (IOAA) in Brazil, securing one gold and four silver medals. Daksh Tayalia from Bengaluru claimed the gold medal, while Aayush Kuthari, Sanidhya Saraf, Banibrata Majee, and Panini won silver medals. This achievement reflects the exceptional talent and dedication of young Indian minds in the field of astronomy and astrophysics.
Scientists have created the most detailed simulations to date of how black holes devour stars, revealing a surprising ‘burping’ phenomenon that explains why these events appear less X-ray bright than expected. These simulations shed light on the messy eating habits of black holes and offer new insights into their growth and evolution.
Scientists have been trying to understand how supermassive black holes form through mergers of smaller black holes. However, simulations have shown that these black holes get stuck in an eternal orbit before merging. A new study suggests that self-interacting dark matter could be the missing ingredient, providing the energy dissipation necessary for the final merger. This discovery not only resolves the ‘final parsec problem’ but also offers insights into the nature of dark matter.
The James Webb Space Telescope (JWST) has captured a stunning new image of the Serpens Nebula, revealing the birth of stars and providing evidence for a long-held theory about their formation. The image shows jets of gas from newborn stars, all aligned in the same direction, supporting the idea that stars form with a consistent spin.
