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 […]

The Hubble Space Telescope has broken the distance limit for galaxies by uncovering a primordial population of ultra-blue galaxies whose light is reaching us now after 13 billion years – just 600 to 800 million years after the Big Bang. Estimating the age of the newly found galaxies was made possible by combining Hubble’s Ultra […]
