Globular clusters draw gasps of wonder when viewed through even modest telescopes. But the Hubble Space Telescope’s view of Messier 14, combining visible, near infrared and ultraviolet wavelengths, is in a class by itself, a stunning sea of tightly-packed stars that defies the imagination. Discovered by comet-hunter Charles Messier in 1764, M14 features and estimated 150,000 suns located some 29,000 light years from Earth in the constellation Ophiuchus. It is well positioned for observing in July. Click into the image below for a larger view.
The gravitational dance between two galaxies in our local neighbourhood has led to intriguing visual features in both as witnessed in this new NASA/ESA Hubble Space Telescope image. The tiny NGC 1510 and its colossal neighbour NGC 1512 are at the beginning of a lengthy merger, a crucial process in galaxy evolution.
