Norman Lockyer

Which element was discovered in the sun before? On Earth, answer helium.

Pierre Janssen and Joseph Norman Lockyer observed helium's distinctive D3 line in the solar spectrum.

It wasn't isolated on Earth until 1895, confirming the celestial discovery.

Question 3.

Neither do we know certainly what becomes of it, but it frequently travels at the rate of 150 miles an hour.

And presuming it to have done so in this instance, carrying the volcanic dust with it, it would, says Mr. Norman Lockyer, have reached various parts of the world exactly at the time when attention was first drawn to the wonderful magnificence and duration of the sunset glow and to other unusual appearances in the sky during the autumn and winter of 1883.

These remarkable sunsets and sunrises began in the Mauritius on the 28th of August and were at once believed to be caused by sunlight passing through fine dust.

And from that time for several months they were constantly observed, now in one place, now in another, until they had been seen almost all over the world, having made their first appearance in England on the 9th of November.
