The JamesWebbSpaceTelescope has got a glimpse into what our galaxy was like in its formative years by observing a distant galaxy called The Sparkler.
Data from the James Webb Space Telescope has given a glimpse into what our galaxy was like in its formative years. Webb observed a galaxy called The Sparkler, which is analogous to what the Milky Way would have been like when it was young, when it had less mass and only a handful of globular clusters.
By contrast, the Sparkler galaxy has just 3% the mass of the Milky Way and only 24 globular clusters. But this small galaxy is growing as it gobbles up nearby satellite galaxies and globular clusters, and it is predicted that it will eventually grow to match the mass of the Milky Way.
