Globular Clusters as Cradles of Life and Advanced Civilizations
Could we find advanced civilizations in the globular clusters orbiting the Milky Way galaxy? The authors of today’s astrobite paper think we might…
Shedding Light on the Epoch of Reionization with Ion2
Ion2 is a compact, intensely star-forming galaxy. With its help we can shed light on one of the most significant transitions the Universe underwent – the very transition from being opaque to see-through.
When did massive structures of galaxies form?
Our current understanding of the Universe suggests that its largest structures, such as clusters and groups of galaxies, would have formed only within the second half of the Universe’s current age. However, today’s paper explores the proposed observational evidence that such structures may actually have began forming a lot earlier than we expected. This poses intriguing questions about the way we model the cosmos, how we interpret our observations, and whether we might need to rethink cosmology.
