  6. William Herschel • 1784: he produced a general catalogue of ~2500 nebular objectsfor which he proposed a classification. One of the classes he named “planetary nebulae” • 1790, he discovered a planetary nebula which he describes in this way: " A most singular phenomenon! A star of about 8th magnitude with a faint luminous atmosphere, of circular form, and about 3 minutes in diameter. The star is perfectly in the center and the atmosphere is so delicate, faint and equally throughout that there can be no surmise of its consisting of stars; nor can there be a doubt of the evident connection between the atmosphere and the star". • This was published in a paper for the Philosophical Transactions of the Royal Astronomy in 1791, with the title "On Nebulous Stars, Properly So Called » NGC 1514 Thus, William Herschel had come to the conclusion that planetary nebulae were nebulous material around a star. Yet we still call them planetary nebulae ! HST view
