English: This Hubble image captures what looks like a galactic glitter bomb in the night sky. Caldwell 104, also cataloged as NGC 362, is a globular star cluster located about 27,000 light-years away. Among the earliest homesteaders of the universe, globular clusters are snow-globe-shaped islands of several hundred thousand (or more) ancient stars. Globular clusters like Caldwell 104 typically reside in a spiral galaxy’s halo, which is a relatively sparsely populated, spherical area that surrounds the galaxy like a shell. They are integral to the birth and growth of their host galaxies.
Caldwell 104 is one of about 150 globular clusters in the Milky Way galaxy, but it stands out from the rest. The cluster is unusually young, as indicated by its composition. Following the Big Bang, the universe consisted only of hydrogen and a little helium. The first stars formed from this material and, through the process of nuclear fusion, spent their lives producing heavier elements, which astronomers call “metals.” But the process can only continue for so long before the stars either run out of fuel or grow unstable. Ultimately, massive stars are doomed to explode in violent events called supernovae, which blast their material out into the cosmos. This stellar detritus is recycled into new generations of stars, so stars that form later contain higher proportions of metals than their older relatives. Astronomers have discovered that Caldwell 104 boasts a surprisingly high metal content, which means that it formed more recently than expected. Most globular clusters are much older than the majority of stars in their host galaxy, but the stars in Caldwell 104 appear to be 2 billion to 3 billion years younger than stars in other Milky Way globulars. Astronomers have used Hubble multiple times to investigate the young cluster’s stellar population. This image was taken in visible light using Hubble's Advanced Camera for Surveys. Discovered from Australia by Scottish astronomer James Dunlop in 1826, Caldwell 104 cannot be viewed from the Northern Hemisphere except near the equator, but it can be seen year-round from mid-Southern latitudes in the constellation Tucana, near the Small Magellanic Cloud. Binoculars or a modest telescope will provide a somewhat hazy view of the magnitude-6.4 cluster, but a large telescope will reveal individual stars.

Сурәт исеме | Globular clusters offer some of the most spectacular sights in the night sky. These ornate spheres contain hundreds of thousands of stars, and reside in the outskirts of galaxies. The Milky Way contains over 150 such clusters — and the one shown in this NASA/ESA Hubble Space Telescope image, named NGC 362, is one of the more unusual ones. As stars make their way through life they fuse elements together in their cores, creating heavier and heavier elements — known in astronomy as metals — in the process. When these stars die, they flood their surroundings with the material they have formed during their lifetimes, enriching the interstellar medium with metals. Stars that form later therefore contain higher proportions of metals than their older relatives. By studying the different elements present within individual stars in NGC 362, astronomers discovered that the cluster boasts a surprisingly high metal content, indicating that it is younger than expected. Although most globular clusters are much older than the majority of stars in their host galaxy, NGC 362 bucks the trend, with an age lying between 10 and 11 billion years old. For reference, the age of the Milky Way is estimated to be above 13 billion years. This image, in which you can view NGC 362’s individual stars, was taken by Hubble’s Advanced Camera for Surveys (ACS). |
