Indian Astronomers Discover 53 New Supermassive Black Hole-Powered Quasars Using Advanced Radio Telescope
A team of Indian astronomers has made a significant discovery of 53 new Giant Radio Quasars, which are highly luminous objects in space powered by supermassive black holes. These findings, made possible by the Giant Meterwave Radio Telescope, provide valuable insights into the behavior of these celestial entities and their role in the universe.
NASA"s TESS Mission Uncovers Rare Binary System Featuring Red Giant Star and Black Hole Companion
Astronomers using NASA"s Transiting Exoplanet Survey Satellite (TESS) have discovered a unique binary system, Gaia BH2, located approximately 3,800 light-years away in the constellation Centaurus, consisting of a red giant star and a black hole companion. This discovery provides valuable insights into the history and evolution of the star.
Sun Emits Powerful X1.9-Class Solar Flare, Disrupting Radio Communications
A strong X1.9-class solar flare occurred on December 1, 2025, causing a brief disruption to radio communications across Australia and parts of southeast Asia. The event triggered a coronal mass ejection, but it is not directed towards Earth.
Newly Discovered Tectonic Regime Sheds Light on Evolution of Rocky Worlds
A recently identified tectonic regime, known as the "episodic-squishy lid," may revolutionize our understanding of how rocky planets evolve and could provide valuable insights into the search for habitable worlds. This newfound knowledge suggests that Earth may have undergone a transitional phase, characterized by periodic bursts of tectonic activity, before developing its current plate tectonics.
The Crucial Role of Exoplanet Atmospheres in the Search for Life Beyond Earth
Astronomers are shifting their focus from solely searching for planets within the habitable zone to also considering the atmospheric conditions necessary for life, with the greenhouse effect playing a critical role in maintaining surface temperatures suitable for liquid water. This new approach has significant implications for the search for life on distant exoplanets.
