The Scorpion doesn't hold as many bright and spectacular deep-sky objects as neighboring Sagittarius, but there are still treats here, including the loose
globular star cluster M4 (NGC 6121), the Cat's Eye Cluster.
Astronomers can measure the ages of
globular clusters by looking at the light of their constituent stars.
As all stars in
globular clusters are believed to have formed together and thus to be roughly the same age, only a difference in mass can give these stars a different color.
Unlike the Wild Duck Cluster, M28 is a
globular cluster located 18,000 light-years away from Earth in the constellation of Sagittarius (the Archer).
So, long answer short: Yes, stars in
globular clusters are still far enough apart for it to be cold between them.
The team, led by MPE's Maximilian Fabricius and including Texas' Eva Noyola, observed 11
globular clusters from the University of Texas at Austin's McDonald Observatory with the Harlan J.
All rats were euthanized at the end of
globular adiponectin or 0.9% saline intervention.
However, the
globular cluster grows gradually brighter towards a tiny, very dense and bright core.
The LMC is rich with many fascinating objects, including
globular clusters, planetary nebulae and open clusters.
The
globular cluster Messier 28 sits just one degree northwest of Lambda, and the two can share a field of view if you use an eyepiece that gives a magnification of 40x or less.
The team restricted its 18-year study to those pulsars that reside in Milky Way
globular clusters--crowded concentrations of several hundred thousand stars.
In this experiment polyalanine was folded into
globular, sheeted and helical structures through the use of carbon nanotubes.
