Much like the Milky Way galaxy did in its infancy. <\/p>\n<p class=\"wp-block-paragraph\">Research co-authors, Professor Duncan Forbes of Swinburne University in Australia and Professor Aaron Romanowsky of San Jose State University in the United States, investigated the age and metallicity of a dozen of the compact star clusters around Sparkler. They determined that several have old formation ages and are metal-rich, similar to ones seen in the bulge of the Milky Way.<\/p>\n<p class=\"wp-block-paragraph\">The mass of our galaxy is mainly made of our stars. Roughly 1.5 trillion of them to be exact. Sparkler is only about 3% of the mass of the Milky Way, but is expected to grow to the current mass of our galaxy over cosmic time. Continued study and observations of Sparkler could help astronomers understand how our home galaxy took shape.<\/p>\n<p class=\"wp-block-paragraph\">\u201cWe appear to be witnessing, first hand, the assembly of this galaxy as it builds up its mass\u2014in the form of a dwarf galaxy and several globular clusters,\u201d Forbes said in a statement. \u201cWe are excited by this unique opportunity to study both the formation of globular clusters, and an infant Milky Way, at a time when the universe was only one-third of its present age.\u201d<\/p>\n<p class=\"wp-block-paragraph\">Romanowsky comments, \u201cThe origin of globular clusters is a long-standing mystery, and we are thrilled that JWST can look back in time to see them in their youth.\u201d<\/p>\n<p class=\"wp-block-paragraph\"><strong>Related stories:<\/strong><\/p>\n<ul class=\"wp-block-list\">\n<li>James Webb reveals protostar cocooned within dark hourglass-shaped clouds<\/li>\n<li>NASA discovers Mars formation resembling the face of a bear<\/li>\n<li>How many exoplanets have been discovered?<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Using the James Webb Space Telescope (JWST), astronomers believe to have found a galaxy that was a near identical image to the Milky Way 13 billion years ago.
