Looking back 11 billion years, astronomers using the Hubble Space Telescope have observed for the first time a spiral galaxy in the early universe, billions of years before other comparable spiral galaxies formed. Current astronomical theories suggest that such “grand-design” spiral galaxies – those with prominent, well-formed spiral arms – simply didn’t exist at such […]

A new computer model suggests that the formation of the first stars depended crucially on the nature of dark matter. Intriguingly, the model also suggests that some of the very first stars that ever formed can still be found in the Milky Way galaxy today. The simulations of the formation of these early stars factored […]
