Astronomy

The book I read to research this post was Astronomy for Dummies by Steven P Maran which is an excellent book which I bought from amazon. Some astronomers especially ones who who work with abstruse physics & robotic telescopes might not have traditional knowledge of the constellations. There are far more amateur astronomers than professionals & a lot have made a useful contribution by things like discovering comets. It worth mentioning some guesthouses & hotels have an inhouse large telescope o r in some cases several & you can go on stargazing weekends. The largest moon in the solar system is one of Jupiters moons called Ganymede & that along with Titan the largest of Saturns moons are larger than Mercury. One of Jupiters moons called Lo is the only body in the solar system along with Earth to have active volcanoes. A probe called Cassini is mapping Jupiters moons. It was claimed there was a rock structure on Mars that resembled a human face & must be man made but scientists now know there's no resemblence. When there are meteor showers they're named after the closest constellation in the region of the sky where they occur with the suffix id added at the end of the word. There are too many stars for them to name all of them but what they do is use the greek alphabet & the brightest star in a constellation is named after that constellation & given the first letter alpha & then they go down in descending order of brightness to the last letter which is omega. Many observatories are located in remote places like Chile where there aren't too many streetlights which pollute the sky with their light & make stargazing difficult.
