Context: <response>: ```Some of the earliest recorded observations ever made through a telescope, Galileo's drawings on 28 December 1612 and 27 January 1613, contain plotted points wey match up with wetin we sabi now say na where Neptune dey. On both occasions, Galileo seems to don mistake Neptune for one fixed star when e appear close—in conjunction—to Jupiter for night sky; hence, e no dey credited with Neptune's discovery. At im first observation for December 1612, Neptune dey almost stationary for sky because e just turn retrograde that day. This apparent backward motion dey happen when Earth orbit carry am pass one outer planet. Because Neptune just dey start im yearly retrograde cycle, the motion of the planet too small well well say Galileo small telescope no fit detect am. For July 2009, University of Melbourne physicist David Jamieson announce new evidence wey suggest say Galileo at least know say the 'star' wey e observe don move relative to the fixed stars.```
