  James Webb Telescope to Study Potentially Hazardous Asteroid 2024 YR4

  Asteroid 2024 YR4, identified in December 2024, has a 2.3% chance of Earth impact in December 2032. Due to uncertainties in ground-based size estimates, JWST will conduct infrared observations in March and May to determine its true dimensions. The European Space Agency estimates its width at 55 metres, but it could be as large as 90 metres. The fin...

  JWST Detects Unexpectedly Massive Black Holes in the Early Universe

  A new study led by Jorryt Matthee of ISTA reveals that black holes in early galaxies were significantly more massive than expected. Using JWST data, researchers found that some black holes accounted for nearly 10% of their galaxy's stellar mass—far exceeding the 0.01% ratio seen in modern galaxies. The findings challenge existing growth models, s...

  Astronomers Discover A Massive Distant Spiral Galaxy from the Early Universe

  Astronomers, using the James Webb Space Telescope (JWST), have identified Zhúlóng, a massive spiral galaxy with a redshift of 5.2. This discovery places the galaxy in a time when the universe was under a billion years old, providing critical insights into early galactic formation. Zhúlóng, named after a mythical Chinese dragon, spans 62,000 lig...

  Researchers Unveil New Theory on the Formation of Jupiter-Mass Binary Objects

  A team of researchers has proposed a new theory explaining the formation of Jupiter-mass binary objects (JuMBOs), identified in 2023 in the Orion Nebula. The theory involves photo erosion, where radiation from massive stars strips away mass from stellar cores, shaping JuMBOs into objects with masses comparable to Jupiter. This theory sheds light on...
