Giovanni Battista Donati

Died 20 Sep 1873 at age 46 (born 16 Dec 1826).Italian astronomer who, on 5 Aug 1864, was first to observe the spectrum of a comet (Tempel 1864 II), showing not merely reflected sunlight but also spectral lines from luminous gas forming the comet tail when near the Sun. Earlier, he discovered the comet known as Donati's Comet at Florence, on 2 Jun 1858. When the comet was nearest the earth, its triple tail had an apparent length of 50°, more than half the distance from the horizon to the zenith and corresponding to the enormous linear figure of more than 72 million km (about 45 million mi). With an orbital period estimated at more than 2000 years, it will not return until about the year 4000.«

Lost Far From A Home

A police car pulls up in front of grandma Bessie's house, and grandpa Morris gets out.
The polite policeman explained that this elderly gentleman said that he was lost in the park...and couldn't find his way home. " Oy Morris ", said grandma, " You've been going to that park for over 30 years ! So how could you get lost ? " Leaning close to grandma, so that the policeman couldn't hear. Morris whispered, " I wasn't lost.....I was just too tired to walk home."
