Since this line did not match any lines from known chemical elements, it was suggested to be due to a new element “nebulium”. They do this all without a brain or even a single. There’s even evidence that slime mold can keep track of time.

In 1864, William Huggins found a bright green emission line in the spectrum of the planetary nebula NGC 6543. 11 epic mysteries scientists totally can’t solve What is the universe made out of When did the anus evolve Can humans live to 150 years old And more By Brian Resnick Bresnick . Slime mold can solve mazes and seems to be able to make risk-benefit decisions. In 1869, a green line was found in the spectrum of the corona of the Sun during the total solar eclipse, and this line was also thought to be a new element and was named “coronium”. The existence of this new element was confirmed by the discovery of its terrestrial counterpart in 1895. In 1868, Norman Lockyer discovered a bright yellow-orange line in the solar spectrum, which he suggested to be due to a new element and named it “helium”. This led to the realization that the Sun is made of the same chemical elements as those of the Earth and marked the demise of the Aristotelian concept of celestial objects being composed of ether. By comparing the Fraunhofer lines with the bright color lines observed in heated chemical elements, Gustav Kirchhoff and Robert Bunsen identified the solar lines as originating from elements sodium, calcium, magnesium, iron, chromium, nickel, barium, copper, and zinc. In 1814, Joseph Fraunhofer observed and tabulated 473 dark lines in the spectrum of the Sun.
