  James Webb Space Telescope Finds Unexpected Ultraviolet Radiation Around Young Protostars

  Astronomers using the James Webb Space Telescope have detected unexpected ultraviolet radiation around five young protostars in the Ophiuchus molecular cloud. Since infant stars are not expected to emit UV light, the finding challenges long-standing star-formation models. Researchers ruled out external illumination from nearby stars, concluding the...

  NASA Hubble Space Telescope Uncovers One of the Youngest Known Blue Straggler–White Dwarf Systems

  Italian astronomers using the Hubble Space Telescope have discovered a white dwarf orbiting a blue straggler star in the globular cluster 47 Tucanae, located 15,300 light-years away. The rare system, among the youngest detected, sheds light on stellar mass transfer and offers vital clues to the evolution of binary stars in dense clusters.

  James Webb Telescope Spots Planet Formation in Harshest Known Galactic Environments

  The James Webb Space Telescope has revealed that planets can form in extreme radiation zones. A protoplanetary disk called XUE 1, exposed to intense ultraviolet light, still shows signs of water and potential for rocky planet formation. The findings challenge old assumptions and broaden the possible regions where Earth-like planets may emerge.

  Is Mars Really Red? A Physicist Explains the Science Behind Its Colour and More

  A physicist explains the science behind Mars’s red appearance, linking its hue to iron oxide or rust. While known as the Red Planet, rover images and telescope data show varied colors, from tan to white ice caps. Observations in ultraviolet and infrared light reveal deeper insights into Mars’s atmosphere, surface, and seasonal changes, enrichin...

  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...
