He described it as a remarkable object and thought it might be a globular cluster.
The bright spot in the top right is a much older globular cluster of thousands of stars.
This is the only globular cluster he could resolve with his moderate instruments, and thus the first globular cluster ever to be resolved.
The estimated mass of the cluster R136 is 450 000 solar masses, suggesting that it will probably become a globular cluster in the future.
This image, taken with the Wide Field Planetary Camera 2 on board the NASA/ESA Hubble Space Telescope, shows the globular cluster Terzan 1.
Scientists have discovered a planet in the globular cluster M4.3(A globular cluster is a very tight, spherical grouping of hundreds of thousands of stars.).
Globular cluster M4 was discovered by De Chéseaux in 1745-46 and listed by him as No. 19, and included in Lacaille's catalog as Lacaille I. 9.
Mayor's research interests include extrasolar planets(also known as exoplanets), instrumentation, statistical properties of double stars, globular cluster dynamics, galactic structure and kinematics.
Collinder(1931) estimated its distance at 12,000 ly, and from its 2.8' angular diameter, speculated if this was an open or a globular cluster.
This computer animation uses real astronomical data to envision a trip through globular cluster NGC 6752, revealing the partially obscured dwarf galaxy Bedin 1 behind it.
The nearest is the globular cluster M4, about 100,000 stars, from our distance of 7200 light years, it is a very safe distance.
Allan Sandage's work focused on globular clusters;
Globular clusters are mainly composed of tens of thousands of very ancient stars, but they also contain some stars that look suspiciously young.
Like many other globular clusters, Messier described it as"Nebula without stars", as did Bode 10 years later;
Some stars in globular clusters appear to be as old as the universe itself(by entirely different measurement and analysis methods)!
This is useful when we have large populations of stars, like globular clusters, but is more difficult for individual stars.
But globular clusters are not static relics from the past-- some curious stellar activities are still going on in these dense star cities.
But globular clusters, like M4, are made primarily of hydrogen and helium, and are practically a dust-free environment.
Globular clusters, also simply known as globular, are star clusters concentrating approximately ten thousand to one million very old stars.
Globular clusters are typically located in the outer regions(the halos) of galaxies, and our Milky Way galaxy has about two hundred of them.
