Genoa, Italy (1625 - 1712)
Giovanni Domenico Cassini was an Italian mathematician, astronomer, engineer, and astrologer. Cassini was an astronomer at the Panzano Observatory, from 1648 to 1669, professor of astronomy at the University of Bologna and became, in 1671, director of the Paris Observatory. Along with Robert Hooke, Cassini is given credit for the discovery of the Great Red Spot on Jupiter (ca. 1665). Cassini was the first to observe four of Saturn's moons, which he called Sidera Lodoicea. Around 1690, Cassini was the first to observe differential rotation within Jupiter's atmosphere.

Algunos días (o major dicho noches) las condiciones del clima nos impiden ir al aire libre y dar una mirada a las maravillas celestiales con un telescopio o simplemente con los ojos. Si una noche lluviosa o nublada lo tiene retenido en casa, puede poner atención a algunos pasatiempos que lo entretendrán y mejorarán su apreciación del universo. Le ofrecemos a continuación dos enlaces para darle algunas ideas.

  • Many of the astronomical ideas and breakthroughs described in 400 Years of the Telescope have inspired science fiction writers as well as PBS viewers. In this guide, we list a few fun science fiction stories on the topics discussed in the show -- stories that work out reasonable scientific ideas in human terms. (Note: This is not a complete list, but just a selection of favorite stories to whet your appetite.)

  • Connections between astronomy and other areas of human culture are easily found in music, where astronomical ideas have found a wide range of expression. The selection of music discussed below is not a comprehensive listing, but just a sampling of some of the pieces that are available on CD's, and that may be of particular interest to astronomy enthusiasts.

    To qualify for the list, a piece (or the composer's vision for it) has to include some real science and not just an astronomical term in the title or in a few lyrics. For example, we do not list The Planets, by Gustav Holst, since it treats the astrological view of the planets. And we regret that Philip Glass' opera Galileo is not available on CD and therefore cannot be listed. Nor do we include the thousands of popular songs that use the moon or the stars for an easy rhyme or a quick romantic image. And, while many jazz pieces have astronomy in the title, it is often hard to know just how the piece and the astronomy go together; so we've sadly omitted jazz too.
