The Oldest Planet Ever Discovered

The video discusses the discovery of the oldest known planet, a gas giant in the Messier 4 globular cluster, which is about 12.7 billion years old. This planet challenges previous assumptions about planetary formation, as it exists in a region where gravitational interactions typically prevent planet formation. The discovery supports the core accretion model, suggesting that heavy elements necessary for planet formation were present nearly 13 billion years ago. This finding provides insights into the early universe and hints at the existence of other ancient worlds.
