According to a new study by NASA’s Spitzer Space Telescope astronomers have discovered that galaxies in the distant, early universe continuously ingested their star-making fuel over long periods of time. This goes against previous theories that the galaxies devoured their fuel in quick bursts after run-ins with other galaxies.NASA’s Spitzer Space Telescope discovered that distant populations of galaxies formed massive, bright stars more commonly than today’s “diet-conscious” galaxies.New study shows the merging of massive galaxies was not the dominant method of galaxy growth in the distant universe.
They are seeing evidence for a mechanism of galaxy growth in which a typical galaxy fed itself through a steady stream of gas, making stars a much faster rate than previously thought. According to new findings, the galaxies fed steadily over periods of hundreds of millions of years and created an unusual amount of plump stars, up to 100 times the mass of our sun.Galaxies like our Milky Way are giant collections of stars, gas and dust. They grow in size by feeding off gas and converting it to new stars.
