I've been studying globular clusters
in galaxies for a long time, and this is the first time I've ever seen this," said Michael Beasley, also of the Instituto de Astrofisica de Canarias.
Caption: The globular cluster
M22 in Sagittarius sparkles with tens of thousands of stars, contains a planetary nebula, and hosts two black holes.
Terzan 5, 19 000 light-years from Earth in the constellation of Sagittarius (the Archer) and in the direction of the galactic centre, has been classified as a globular cluster
for the forty-odd years since its detection.
Omega Centauri (NGC 5139) - This is the largest and brightest globular cluster
in the sky.
From our vantage point on Earth, the center of a globular cluster
appears so densely packed that we can't see any empty space between its stars.
html) and the current view is that this massive globular cluster
, one of the oldest objects in the Milky Way, may be a dwarf galaxy stripped of its outer stars.
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.
Ancient globular clusters
such as M4 were thought to be the last place to find planets because they contain very little metal, which is considered an essential raw material for planet formation.
The planet, located in the M4 globular cluster
(5,680 light-yrs away), was speculated to be a planet in the early 1990's when astronomers found some irregularities within the movement of two nearby stars.
You can't draw a globular cluster
and make it look like a globular cluster
The heart of a globular cluster
of stars appears as a shimmer carpet of jewels.
The study appeared in the Monthly Notices of the Royal Astronomical Society under the title "A detached stellar-mass black hole candidate in the globular cluster
Titled "A detached stellar-mass black hole candidate in the globular cluster
NGC 3201," it is set to appear in the journal Monthly Notices of the Royal Astronomical Society.
I'm speaking, of course, about M13, the Great Globular Cluster
Almost 95 percent of globular cluster
formation occurred within the first 1 billion to 2 billion years after our universe was born in the theorized Big Bang 13.
