ISRO’s AstroSat Observes First-Ever Nuclear Explosion in Andromeda Galaxy
Using the Ultraviolet Imaging Telescope (UVIT) aboard ISRO’s AstroSat, scientists have identified far-ultraviolet emissions from 42 novae in the Andromeda Galaxy. This marks the first detection of such emissions during their outbursts, offering new insights into the processes of stellar explosions. Four of these novae were observed in real-time a...

Here's How Nuclear Clocks Could Redefine Time and Reshape Modern Technology
Timekeeping is entering a new era with nuclear clocks, capable of achieving accuracy to the 19th decimal place. Current atomic clocks rely on caesium-133, but innovations with thorium-229’s nuclear transitions, excited by ultraviolet light, promise unprecedented precision. Scientists aim to redefine the second using elements like strontium by 203...

Jupiter’s Earth-Sized Storms Might Be Caused by Magnetic Tornadoes, Study Claims
Magnetic tornadoes twisting down from Jupiter's ionosphere create massive, Earth-sized anticyclonic storms in the planet's atmosphere. These dark ovals, detectable only in ultraviolet light, form dense hazes of aerosols stirred by swirling magnetic vortices. This phenomenon, visible at Jupiter's poles, was unveiled through data from the Hubble Spac...

Hubble Telescope Finds Unexpectedly Hot Accretion Disk in FU Orionis
Hubble Space Telescope’s recent observations of FU Orionis have revealed surprising new details about the star’s accretion disk. The study found that the disk’s inner edge reaches temperatures as high as 16,000K, nearly three times hotter than the Sun’s surface. This discovery challenges existing models of stellar accretion, which had predi...

NASA James Webb Space Telescope Unearths Oversupply of UV Light from Early Stars and Black Holes
NASA’s James Webb Space Telescope (JWST) has revealed surprising new details about the universe's reionization process. The telescope has found an unexpected oversupply of ultraviolet (UV) light emitted by early stars and giant black holes, contradicting previous theories. This discovery suggests a more complex reionization process, potentially d...
