Scientists using NASA's Chandra X-ray Observatory and eROSITA have identified a neon pink 'treble clef' shape in space as a merging galaxy cluster, where a supermassive black hole outburst created bright radio waves.

01Summary

  1. 01The treble clef shape was observed using NASA's Chandra X-ray Observatory and the German eROSITA X-ray telescope.
  2. 02The object is a huge galaxy cluster made of two clusters in the process of merging.
  3. 03A supermassive black hole outburst pushed charged particles and magnetic fields away, producing bright radio waves.
  4. 04A subsequent collision between the galaxy clusters likely reenergised the particles, amplifying the radio signal.
  5. 05The findings were published in the journal Astronomy & Astrophysics.

02Why it matters

This discovery reveals how supermassive black holes can shape their environment, and shows that violent cosmic events can create the stunning patterns we see in space images.
