we found that a comprehensive picture of the cluster AMR can be obtained, which includes the following components: two enhanced formation processes at t 2 and 56 Gyr, which have taken place throughout the entire body of the galaxy; the absent of a metallicity gradient and a relative spread ...
A Japanese space observatory has revealed the clearest view yet of the dusty Perseus galaxy cluster 250 million light-years from Earth. The new observations were taken in the X-ray range of the light spectrum by the Suzaku spacecraft, whose name is Japanese for "red bird of the south." Th...
Using a telescope the size of the planet, astronomers have captured the first image of this space oddity. Here's why that matters.
Explanation: After the Crab Nebula, M1,this giant star cluster is the second entry in 18th century astronomer CharlesMessier's famous list of things that are not comets. M2 is one of the largestglobular star clusters now known to roam the halo of our Milky Way galaxy.Though Messier originall...
of millions of years.They will probably collide again and again over the next billion years untilthey coalesce to form a single galaxy. NGC 4676 lies about 300 millionlight-years away toward the constellation of Bernice's Hair (Coma Berenices)and are likely members of the Coma Cluster of ...

Humans vs Aliens vs Robots is a series of three intertwined strategy multi player games. The outcomes and events in each game can affect the other games, and it's up to you what games you play and how you play them. War: Take command of your civilization and capture a cluster of stars...
Collinder 427 is just to the right of NGC 7023 itself in this fabulous image, but that's close enough for me to mention it, though as a poorly detached cluster with relatively few stars it isn't really the highlight here. However with the advent of the Caldwell Catalogue (NGC7023 is ...
The tip of this dense gaseous structure hides a group ofprotostars as imaged by Spitzer. This HII region contains a number of these dark dense regions holding out against the ultraviolet onslaught of the blue supergiant star in the centre of the Tr 37 cluster, just above the tip of the ...
