magnetosphere
"The second result announced today came from Pontus Brand of Cassini's magnetosphere imaging team. The magnetosphere is like a magnetic bubble where planets' magnetic fields interact with the solar wind. Cassini measured hot plasma explosions in Saturn's magnetosphere"
"The Earth's magnetosphere is like a huge and impalpable cocoon that surrounds our planet, forming a protective shield valuable because deflects cosmic radiation from both the Sun and from other distant cosmic sources."
METAMIA is a free database of analogy and metaphor. Anyone can contribute or search. The subject matter can be anything. Science is popular, but poetry is encouraged. The goal is to integrate our fluid muses with the stark literalism of a relational database. Metamia is like a girdle for your muses, a cognitive girdle.
