👤 whose
Whose discovery made helium the first element found in the Sun before Earth?
Quick Answer
Pierre Janssen and Norman Lockyer’s. In 1868, they identified helium in the Sun’s spectrum before it was isolated on Earth.
The Full Story
During the 1868 solar eclipse, Pierre Janssen observed a new spectral line in the Sun’s atmosphere. At nearly the same time, Norman Lockyer independently saw the same line and concluded it came from a new element. They named it helium after Helios, the Sun, even though it was not isolated on Earth until 1895. This was a landmark moment for spectroscopy and astronomy. It showed that chemical elements could be identified remotely from light.
