Galileo Galilee was a scientist, philosopher, mathematician.
Born February 15, 1564, Galileo Galilee was a scientist, philosopher, mathematician, professor, optician, musician, painter, and father of three. Despite all these accomplishments, it is easy to conceive that - like many amateur Astronomers of today - one of his greatest loves was to turn eye and telescope upon the wonders of the night sky. In this article by Astro.Geekjoy's Jeff Barbour we retrace a few of his steps and come to a deeper insight into the kinds of questions driving his personal quest for understanding.
Radio Telescopes around the world listened for signals from Huygens to measure wind speeds on Titan as the probe descended through its atmosphere last month. The Telescopes discovered that winds on Titan are very weak near the surface, and then increase in intensity with altitude. Huygens passed through winds going nearly 435 kph (270 mph) at an altitude of 120 km (75 miles). Cassini was originally supposed to make these measurements, but there was a configuration problem with one of its receivers.
NASA has released new colour images of Saturn's northern hemispheres taken by Cassini - and the Ringed planet is looking a little blue. This blue colour of Saturn's atmosphere is probably linked to the cloud-free nature of the upper atmosphere, but imaging scientists still aren't really sure. Icy Moon Mimas is set against the image, and a few large craters are visible on its surface. This image was taken on January 18, 2005, when the spacecraft was approximately 1.4 million kilometers (870,000 miles) from Saturn.
