NGC-0055-PIA04923.jpgNGC 55 - Spiral Galaxy60 visite"...Credo che il giusto è un istrion beffardo,
E nel viso e nel cuor,
Che tutto è in lui bugiardo:
Lagrima, bacio, sguardo,
Sacrificio ed onor..."

HD-189733b-SST.jpgHD 189733b: Hot Jupiter60 visiteCaption NASA:" HD 189733b is a Jupiter-sized planet known to orbit a star some 63 LY away. But while the distant world is approximately the size of Jupiter, its close-in orbit makes it much hotter than our Solar System's ruling Gas Giant.
Like other detected hot Jupiters, its rotation is tidally locked -- one side always faces its parent star as it orbits once every 2,2 (Earth) days. Using infrared data from the Spitzer Space Telescope, this Planet's temperature variations have been mapped out -- the first map ever made for a planet beyond our Solar System.
Seen here (brighter colors = higher temperatures), the hottest spot on the Planet is not at longitude 0,0°, the point exactly facing the Parent Star.
Instead, it's about 30° to the East (right), evidence that fierce, Planet circling winds influence the temperature. In the Planet-wide map, the temperature measurements vary from about 930 to 650° Celsius (such as 1.700 to 1.200 F)". MareKromium
