Scientists spot more Milky Way-like galaxies in early universe

Scientists are peering into the past and uncovering new clues about the early universe. Since light takes a long time to travel through space, they are now able to see how galaxies looked billions of years ago. The astronomers have discovered that spiral galaxies were more common in the early universe than previously thought. The scientists found that nearly 30% of galaxies have a spiral structure about 2 billion years after the universe formed. The discovery provides a significant update to the universe s origin story as previously told using data from NASA s Hubble Space Telescope.

Wind from black holes may influence development of surrounding galaxies

Clouds of gas in a distant galaxy are being pushed faster and faster at more than 10,000 miles per second out among neighboring stars by blasts of radiation from the supermassive black hole at the galaxy s center. It s a discovery that helps illuminate the way active black holes can continuously shape their galaxies by spurring on or snuffing out the development of new stars.
