Sir Joseph Norman Lockyer was born on May 17th 1836 in Rugby. He has two main claims to fame: founding the journal Nature (which I used to read occasionally until I realized I couldn’t understand a word of it) and the discovery of helium, which, because he first identified it in solar spectra, he named after the handsome Greek god of the Sun, Helios.
1887 – Asteroid 266 Aline discovered by Johann Palisa. Aline is a C-type asteroid in the main belt, and measures a chunky 108(-ish) km in diameter. According to the Dictionary of Minor Planet Names by Lutz D Schmadel, the name might be a nod to Linda (“Aline”) Weiss, one of the seven children of the director of Vienna Observatory, Edmund Weiss.
