- Hubble Observations Give Forgotten Globular Cluster Its Moment to Shine July 5, 2025NASA’s Hubble Space Telescope has unveiled ESO 591-12, a long-overlooked globular cluster glittering with multicolored stars. Captured during a survey of missing clusters, this image provides new insight into stellar evolution and the early Milky Way. It marks a vital step in resolving the structure and origin of ancient star systems hidden within our galaxy.
- Very Massive Stars Blow Away Outer Layers in Powerful Winds Before Black Hole Collapse July 5, 2025Massive stars may lose much more mass than expected before collapsing into black holes. A new study reveals that their powerful stellar winds strip outer layers early, reshaping theories of star evolution, black hole formation, and gravitational wave events. This research challenges previous models and helps explain observed features of stars like R136a1 in the […]
- Astronomers Capture First-Ever Image of a Dead Star That Exploded Twice in Rare Supernova Event July 5, 2025Astronomers have captured the first-ever image of a white dwarf star undergoing a rare double-detonation supernova. Using the Very Large Telescope, the team revealed that such explosions can occur without a star reaching the Chandrasekhar limit. The findings, published in Nature Astronomy, could reshape existing theories about stellar death and improve our understandi...
- Climate Satellite MethaneSAT Fails After Just One Year in Orbit July 5, 2025MethaneSAT, a climate-monitoring satellite backed by Google and the Bezos Earth Fund, has failed after just one year in orbit. Launched in March 2024 to track methane leaks, the $88 million satellite lost power in June 2025. Though unrecoverable, mission operators will continue analyzing the collected data to support climate action and emission transparency efforts.
- New Interstellar Comet 3I/ATLAS Speeds Through Solar System July 5, 2025Astronomers have identified 3I/ATLAS as the third confirmed interstellar comet, racing through the solar system at 68 km/s. Discovered on July 1, it will pass near the sun in October. Skywatchers can view this rare object live online tonight, thanks to a live stream by the Virtual Telescope Project using observatories in Italy.
- The Hunt: Rajiv Gandhi Assassination Now Available For Streaming on SonyLIV July 5, 2025SonyLIV’s The Hunt: Rajiv Gandhi Assassination stands out as a political crime docu-series that captures the emotional and investigative journey following one of India’s darkest chapters. Directed by Nagesh Kukunoor, the show relies on archival footage, interviews, and reenactments to portray the events surrounding the 1991 suicide attack.
- Best Window ACs under Rs 30,000 in India (July 2025): Carrier, Voltas, Lloyd, and More July 5, 2025With temperatures soaring high in India, the demand for air conditioners (ACs) has never been higher. For smaller rooms, a window AC can be a compelling option due to the ease of installation, lower maintenance costs, and portability. To help you make an informed purchase, we have curated a list of the best window ACs […]
- CSIRO Uses Quantum AI to Revolutionize Semiconductor Design July 4, 2025In a global first, researchers at Australia’s CSIRO used quantum machine learning to enhance semiconductor design, outperforming classical AI models. By modeling Ohmic resistance in GaN transistors, the team built a hybrid quantum–classical model using just 5 qubits. This Quantum Kernel-Aligned Regressor revealed subtle fabrication patterns that classical methods ...
- Metamaterial Breaks Thermal Symmetry, Enables One-Way Heat Emission July 4, 2025Scientists have created a groundbreaking metamaterial that breaks Kirchhoff’s law by emitting 43% more mid-infrared radiation in one direction than it absorbs. Built from layered InGaAs and tested at 512°F with a 5T magnetic field, the structure exhibits record thermal nonreciprocity. This breakthrough enables controlled one-way heat flow, a step toward thermal dio...
- NASA TEMPO Satellite to Continue Tracking Pollution Hourly from Space Until 2026 July 4, 2025TEMPO, a collaborative space mission by NASA, NOAA, and the Smithsonian Astrophysical Observatory, is transforming air quality tracking across North America. Since 2023, it has delivered hourly, high-resolution pollution data from space, aiding researchers, health officials, and the public.
