Summary:
- Researchers have discovered a massive, solid rock and iron "mega-blob" deep beneath the Hawaiian Islands. This blob is about 1.8 times the size of the Big Island of Hawaii.
- The mega-blob is not a molten, gooey mass as previously thought, but rather a solid structure made up of dense rock and iron. This finding challenges previous theories about the formation of the Hawaiian Islands.
- The mega-blob may be fueling the volcanic activity and hotspot that has created the Hawaiian Islands over millions of years. Understanding the nature and composition of this massive structure can provide valuable insights into the geological processes shaping our planet.
