  NASA’s James Webb Space Telescope Reveals the Complex Structure of a Planetary Nebula

  NASA's James Webb Space Telescope has unveiled the complex character of NGC 1514, a planetary nebula developing over at least 4,000 years. Only seen in infrared light, the nebula's rings now resemble "fuzzy" clusters set in twisted patterns. A network of sharper holes near the centre stars indicates where faster material punched through.

  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...
