Galileo’s drawing my drawing my sketch of Jupiter’s rotation Galileo published his observations in Sidereus Nuncius in March 1610: “On the 7th day of January in the present year, 1610, in the first hour of the following night, when I was viewing the constellations of the heavons through a telescope, the planet Jupiter [...]
nine-day moon Lunar creature features Rabbit on the full moon Night owls can enjoy the nine-day moon – it’s up all night long. In my sketch, the magnificent crater Copernicus is visible on the sunlit side of the terminator – on the right side of the lunar center. It looks so insignificant right now, but [...] Six-day old waxing moon The six-day waxing gibbous moon is visible for many hours in the evening – perfect for lunar observing and sketching. The time of my sketch was closer to the sixth day than the five day old moon. I had a hard time identifying craters using either lunar days! Note how much [...] three-day old waxing moon This year, my observing project is to recreate as many of Galileo’s original telescopic observations as I can. I’ll be using my smallest telescope, a 70mm refractor, and making my sketches using a 25mm eyepiece for a magnification of 19x. Each of my lunar sketch pages will each show three [...] Galileo's sunspots My sunspots In the summer of 1612, Galileo sketched a series of sunspots which were published in Istoria e Dimostrazioni Intorno Alle Macchie Solari e Loro Accidenti Rome, (History and Demonstrations Concerning Sunspots and their Properties), in 1613. Galileo corresponded with other scientists and artists who also were sketching the [...] Galileo’s Trapezium My Trapezium sketches
Galileo’s observed the Trapezium stars in the sword of Orion on February 4, 1617. He labeled the three stars “c”, “g”, and “i”. These stars are known now as the “D”, “C” and “A” components of Theta 1 Orionis, or 41 Orionis. He did not see the fainter [...] Folio page 28 manuscript copy of Sidereus Nuncius sketch of 3-day old waxing moon 2-28-09 sketch of 5-day old waxing moon sketch of 14-day (full) moon 3/11/09 Galileo’s watercolor drawings were made with brown ink wash on watercolor paper. To me, these are the most beautiful of Galileo’s astronomical renderings. When I look at the [...] Galileo telescope replica and my TV Ranger Galileo's 1609 telescope There were separate housings at either end for the objective and the eyepiece When I started thinking about how to integrate International Year of Astronomy into my 2009 What’s Up podcasts I naturally focused on Galileo’s first observations through a telescope 400 years [...] |
