Johannes Hevelius, the Polish astronomer who introduced this constellation in his star catalogue of 1687, continued to measure star positions with the naked eye long after other astronomers had adopted telescopic sights. The French astronomer Pierre Gassendi (1592–1655) wrote in 1644 that Hevelius had the ‘eyes of a lynx’ and this constellation can be seen as an attempt to demonstrate that.[note] Indeed, Hevelius wrote in the Introduction to his catalogue that anyone who wanted to observe it would need the eyesight of a lynx (‘oculos habeat Lynceos’), although he undoubtedly exaggerated the faintness of the 19 stars he catalogued in it, typically by a full magnitude.
- Spring (season) (Wikipedia)
Spring, also known as springtime, is one of the four temperate seasons, succeeding winter and preceding summer. There are various technical definitions of spring, but local usage of the term varies according to local climate, cultures and customs. When it is spring in the Northern Hemisphere, it is autumn in the Southern Hemisphere and vice versa. At the spring (or vernal) equinox, days and nights are approximately twelve hours long, with daytime length increasing and nighttime length decreasing as the season progresses until the Summer Solstice in June (Northern Hemisphere) and December (Southern Hemisphere).
