M45: The magnificent Pleiades (seven sisters) star cluster

[CLICK ON IMAGE FOR HIGH RESOLUTION, Marco Lorenzi (Glittering Lights) Perhaps the most famous star cluster on the sky, the bright stars of the Pleiades star cluster can be seen without binoculars from even the depths of a light-polluted city. With a long exposure from a dark location, though, the dust cloud surrounding the Pleiades […]

Even before Hubble magic, there was the magnificent Horsehead Nebula

[CLICK ON IMAGE FOR HIGH RESOLUTION, Giuseppe Carmine Iaffaldano; Processing: Roberto Colombari] Sculpted by stellar winds and radiation, a magnificent interstellar dust cloud by chance has assumed this recognizable shape. Fittingly named the Horsehead Nebula, it is some 1,500 light-years distant, embedded in the vast Orion cloud complex. About five light-years “tall”, the dark cloud […]

Red sunset from green Earth, blue sunset from red Mars

[CLICK ON IMAGE FOR HIGH RESOLUTION, Left Image: Damia Bouic; Right Image: NASA, JPL-Caltech] How different does sunset appear from Mars than from Earth? For comparison, two images of our common star were taken at sunset, one from Earth and one from Mars. These images were scaled to have same angular width and featured here […]
