A Little Astronomy
The Hubble Space Telescope is a robotic telescope located on the outer edge of the atmosphere, in circular orbit around the Earth at 593 km above sea level, with an orbital period between 96 and 97 minutes at a speed 28,000 km / h. Named as a tribute to Edwin Hubble, was launched into orbit on 24 April 1990 as a joint project of NASA and ESA, thus inaugurating the Great Observatories program. Cylindrically shaped Hubble weighs 11 tons. Its length is 13.2 m and its maximum diameter is 4.2 meters. The telescope can obtain images with higher optical resolution 0.1 seconds of arc. 哈勃太空望遠鏡是一個機器人望遠鏡位於外大氣層,在環形軌道上圍繞地球五百九十三公里海拔,軌道間96和97分鐘,速度二點八萬公里/小時,命名埃德溫哈勃, 1990年4月24日發射進入軌道作為一個聯合項目,美國航太局和歐空局,從而開創了大天文台計劃。圓柱狀哈勃重量11噸。其長度為13.2米,最大直徑為4.2米。 這架望遠鏡能夠獲得更高的光學圖像的第0.1秒的弧。
First we see the Galaxy Hat, also called M 104 in the Messier catalog, distance of about 28 million light-years it is considered the best photograph taken by Hubble. 首先,我們看到銀河系紅帽,也稱為M 104在梅西爾目錄,距離約為28萬光年它被認為是最好的照片由哈勃拍攝。
