M45: The magnificent Pleiades (seven sisters) star cluster

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 […]

Neighboring galaxy is same size as our own

Neighboring galaxy is same size as our own

[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 […]

Case of the one-armed spiral galaxy NGC 4725

Case of the one-armed spiral galaxy NGC 4725

[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 […]

Almost every item in this photo is a galaxy

[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 […]

[CLICK ON IMAGE for High Resolution / Tony Hallas Big, beautiful spiral galaxy NGC 7331 is often touted as an analog to our own Milky Way. About 50 million light-years distant in the northern constellation Pegasus, NGC 7331 was recognized early on as a spiral nebula and is actually one of the brighter galaxies not […]

Lagoon Nebula: Baby stars on board

[CLICK ON IMAGE FOR HIGH RESOLUTION, Hubble Legacy Archive, NASA, ESA, Judy Schmidt] The center of the Lagoon Nebula is a whirlwind of spectacular star formation. Visible near the image center, at least two long funnel-shaped clouds, each roughly half a light-year long, have been formed by extreme stellar winds and intense energetic starlight. The […]

Cluster of 10 million stars: Part of Milky Way or its own galaxy?

[FOR HIGH RESOLUTION CLICK ON IMAGE,CEDIC Team, Processing – Christoph Kaltseis] Globular star cluster Omega Centauri, also known as NGC 5139, is some 15,000 light-years away. The cluster is packed with about 10 million stars much older than the Sun within a volume about 150 light-years in diameter, the largest and brightest of 200 or […]

Nearby M7 star cluster stands out in a sea of … stars, farther away at our galaxy’s center

[CLICK ON IMAGE FOR HIGH RESOLUTION, Lorand Fenyes] M7 is one of the most prominent open clusters of stars on the sky. The cluster, dominated by bright blue stars, can be seen with the naked eye in a dark sky in the tail of the constellation of the Scorpion (Scorpius). M7 contains about 100 stars […]
