(spherical collections of up to a million densely packed stars found in galactic haloes) could be factories of binary black holes (two black holes in close orbit around each other); and The sensitive new observatories potentially could detect 100 merging binary black holes per year forged in the cores of these dense star clusters.
The globular star cluster in Abell 1689 is roughly twice as large as any other population found in previous globular cluster
surveys -- in comparison, our Milky Way galaxy hosts about 150 -- and constitutes the most distant such systems ever studied, at 2.
The astronomers believe the older stars started cooling down and expelled gas into the globular cluster
Huge clouds of interstellar gas, open clusters of stars and distant globular clusters
sprinkle the area.
Previous measurements of two pulsars in the globular cluster
Terzan 5, reported by Freire's team in 2005, also suggest that some neutron stars are heavier than quark models might allow.
This class of solutions will be seen to account for the "black holes" observed in galaxies and globular cluster
The best object to view from UK skies is the globular cluster
Moving away from planets we can see M15,a nice globular cluster
at the front edge of Pegasus (the wingedhorse).
You can't draw a globular cluster
and make it look like a globular cluster
The stream they tested the new technique on was produced by a globular cluster
named Palomar 5, and had already been discovered in 2001 high above the Galactic disk.
The brightest globular cluster
, readily visible to the naked eye, is Omega Centauri, not far from Crux.
Serpens is known for the beautiful globular cluster
NGC 5904 (better known as Messier 5), which is situated 3 degrees further south of NGC 5921.
Pegasus is home to M15, a globular cluster
that lies on the constellation's western fringes close to the border with Equuleus.
Researchers led by Harvey Richer of the University of British Columbia in Vancouver combined recent Hubble observations with eight years' worth of data from the telescope's archive to determine the motions of the stars in the globular cluster
47 Tucanae, which is located about 16,700 light-years away in the southern constellation Tucana.
In an open cluster, stars are gathering debris and gas, becoming much larger over time but are not as gravitationally bound to one another as the ancient stars found in a globular cluster
