Scientists Discover Oxygen in Distant Galaxy, Revolutionizing Cosmic Understanding

INIndia|

Astronomers discovered traces of oxygen in the galaxy JADES-GS-z14-0, located 13.4 billion light years from Earth, according to research conducted using the ALMA radio telescope. This finding, announced on March 21, 2025, contradicts prior scientific expectations and suggests that the galaxy contains ten times more heavy elements than initially predicted for its age.

Identified by the James Webb Space Telescope in 2023, JADES-GS-z14-0 existed merely 300 million years after the Big Bang during the "Cosmic Dawn" era, a formative period in the universe's timeline. Sander Schouws of Leiden Observatory remarked that this discovery is akin to finding a teenager among expected newborns, indicating rapid star formation and evolution contradicted existing theories about early galaxies.

Italian astrophysicist Stefano Carniani called the discovery "incredible," emphasizing the need for updated models regarding galaxy formation. These revelations contribute to a growing body of evidence suggesting that early galaxies were more advanced than previously thought, prompting a reevaluation of the timeline for cosmic evolution.

Pune Techie Confesses to Son's Murder Amid Marital Suspicions

In a tragic incident in Pune, a 38-year-old techie, Madhav Tiketi, allegedly murdered his three-and-a-half-year-old son, Himmat, over suspicions of infidelity regarding his wife, Swaroopa. The shocking event unfolded in the Chandan Nagar area, where Tiketi was later found intoxicated at a local lodge. According to police reports, a domestic dispute ensued Thursday afternoon, leading Tiketi to leave the house with his son. Surveillance footage tracked their movements, showing Tiketi purchasing clothes alone hours later. When Swaroopa reported her husband and son missing later that evening, police initiated a search, locating Tiketi through his mobile phone signals. After regaining consciousness, Tiketi confessed to killing Himmat, leading authorities to a nearby forest, where they discovered the child’s body with a fatal throat cut. A senior police official stated that Tiketi has been taken into custody, and a murder case has been registered. The child's remains have been sent for a post-mortem examination as investigations continue.

Astronomers Discover Oxygen in Galaxy 13.4 Billion Light-Years Away

Scientists have detected signs of oxygen in the galaxy JADES-GS-z14-0, located 13.4 billion light-years from Earth, during research using the ALMA radio telescope. This discovery, confirmed by astronomers from the Netherlands and Italy, challenges existing theories regarding the early universe's star formation, as reported by the European Southern Observatory. First identified by the James Webb Space Telescope in 2024, JADES-GS-z14-0 existed when the universe was merely 300 million years old. The presence of oxygen suggests the galaxy contains ten times more heavy elements than expected for galaxies from the “Cosmic Dawn” era, as detailed by astronomer Sander Schouws from Leiden Observatory. He likened the finding to discovering a teenager in a region thought to be populated only by newborns. These unexpected results indicate that galaxies formed and evolved much more quickly than previously theorized, prompting scientists to reevaluate their understanding of cosmic history, according to Italian astrophysicist Stefano Carniani.

Record Ocean Heat Signals Urgent Climate Crisis, Say Researchers

A recent study has revealed that global sea surface temperatures soared to unprecedented levels between April 2023 and March 2024, exceeding previous records by approximately 0.25°C. According to researchers from the University of Bern, Switzerland, this event, classified as a one-in-512-year occurrence, has been attributed to ongoing global warming and human-induced climate change. The study highlights alarming consequences of prolonged ocean heat, which includes intensified marine heatwaves that can lead to mass die-offs of marine species and accelerated coral bleaching. Researchers caution that such changes also disrupt regional climate patterns, notably affecting monsoon conditions in India, which could threaten food and water security. Despite initial concerns that global warming may have accelerated, the study affirms that current climate models are capable of simulating these extreme temperature jumps. Projections indicate that temperatures are expected to return to the long-term warming trend by September 2025, although sea surface temperatures have remained above historical averages since mid-2024. The findings have sparked discussions among scientists, emphasizing the need to monitor ocean temperatures closely as they continue to influence global climate systems.
