His discovery turned out to be a supernova, the first visible to the naked eye since Johannes Kepler observed SN 1604 nearly 383 years prior.
The former marked the first time a nova's spectrum had been photographed, while the latter eventually reached magnitude 0.2 to become the brightest nova in history since the supernova SN 1604, though it was later topped by Nova Aquilae 1918.
'New stars' (in particular two supernovas, Tycho's Nova of 1572, and Kepler's Nova of 1604), that suddenly appeared, having a white colour in the brightest phase, then turning to yellow and red, and finally fading out.
