June 16, 2016 CLICK ON IMAGE FOR HIGH RESOLUTION, European Southern Observatory, Aniello Grado and Luca Limatola Named for the southern constellation toward which most of its galaxies can be found, the Fornax Cluster is one of the closest clusters of galaxies. About 62 million light-years away, it is almost 20 times more distant than […]
[CLICK ON IMAGE FOR HIGH RESOLUTION, Mads Fredslund Andersen, Stellar Astrophysics Centre, Aarhus Univ., Denmark] Near first quarter, the Moon in March lights this snowy, rugged landscape, a view across the top of Tenerife toward La Palma in the Canary Islands Spanish archipelago. The large Teide volcano, the highest point in Spain, looms over the […]
[CLICK ON IMAGE FOR HIGH RESOLUTION, Roberto Colombari] This huge ball of stars predates our Sun. Long before humankind evolved, before dinosaurs roamed, and even before our Earth existed, ancient globs of stars condensed and orbited a young Milky Way Galaxy. Of the 200 or so globular clusters that survive today, Omega Centauri is the […]
[CLICK ON IMAGE FOR HIGH RESOLUTION, Malcolm Park (North York Astronomical Association)] Separated by about 14 degrees (28 Full Moons) in planet Earth’s sky, spiral galaxies M31 at left, and M33 are both large members of the Local Group, along with our own Milky Way galaxy. This narrow- and wide-angle, multi-camera composite finds details of […]
[CLICK ON IMAGE FOR HIS RESOLUTION, Hubble Heritage Team (AURA/STScI /NASA)] Why does the Sombrero Galaxy look like a hat? Reasons include the Sombrero’s unusually large and extended central bulge of stars, and dark prominent dust lanes that appear in a disk that we see nearly edge-on. Billions of old stars cause the diffuse glow […]
[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 […]
[CLICK ON IMAGE FOR HIGH RESOLUTION, Petri Kehusmaa, Harlingten Atacama Observatory] Large spiral galaxy NGC 4945 is seen edge-on near the center of this cosmic galaxy portrait. In fact, NGC 4945 is almost the size of our own Milky Way Galaxy. Its own dusty disk, young blue star clusters, and pink star forming regions standout […]
[FOR HIGH RESOLUTION, CLICK ON IMAGE, Credit & Copyright: Martin Pugh] While most spiral galaxies, including our own Milky Way, have two or more spiral arms, NGC 4725 has only one. In this sharp color composite image, the solo spira mirabilis seems to wind from a prominent ring of bluish, newborn star clusters and red […]
[CLICK ON IMAGE FOR HIGH RESOLUTION, Babak Tafreshi (TWAN)] In the coming days, Venus shines near the western horizon at sunset. To find Earth’s sister planet in twilight skies just look for the brilliant evening star. Tonight very close to the Pleiades star cluster, Venus dominates this springtime night skyscape taken only a few days […]
[CLICK ON IMAGE FOR HIGH RESOLUTION, NASA, ESA, Hubble] The Coma Cluster of Galaxies pictured above is one of the densest clusters known – it contains thousands of galaxies. Each of these galaxies houses billions of stars – just as our own Milky Way Galaxy does. Although nearby when compared to most other clusters, light […]
