PASAD stanley en mexico ENA, Calif. -- Galaxies once thought of as voracious tigers are more like grazing cows, according to a new study using 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. Our study shows the merging of massive galaxies was not the dominant method of galaxy growth in the distant universe, said Ranga-Ram Chary of NASA s Spitzer Science Center at the California Institute of Technology in Pasadena, Calif. We re finding this type of galactic cannibalism was rare. Instead, we are seeing evidence for a mechanism of galaxy growth in w stanley tumbler hich a typical galaxy fed itself through a steady stream of gas, making stars at a much faster rate than previously thought. Chary is the principal investigator of the research, appearing in the Aug. 1 issue of the Astrophysical Journal. According to his findings, these grazing 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. This is the first time that we have identified galaxies that supersized themselves by grazing, said Hyunjin Shim, also of the Spitzer Science Center and lead author of the paper. They have many more massive stars than our Milky Way galaxy. Gal stanley tumbler axies like our Milky Way are gia Gafq Live-Action Grand Admiral Thrawn Gets a Worthy Collectible

As around three-quarters of the emissions that cause climate change come from energy, we at the International Energy Agency have turned th stanley tumblr is net-zero target into a road map for the energy sector. What needs to happen We have described more than 400 milestones: for example, in 2030, 60% of cars sold should be electric vehicles, compared with 5% today. By 2040, half of all flights should be using sustainable fuels and the world needs to have phased out all coal and oil power plants where emissions arenrsquo;t captured.Read More: China Is Planning to Build 43 New Coal-Fired Power Plants. Can It Still Keep Its Promises to Cut Emissions If we do these things, are we sure we will keep the global temperature rise to 1.5ordm;C The answer is, Irsquo;m not sure. But, even if we donrsquo;t succeed entirely, if we do our best and foll stanley italia ow this road map, we will still help avoid the worst of climate change. If we cannot reach 1.5ordm;, then 1.6ordm; or 1 stanley cup .7ordm; is still far better than 3.5ordm;, where the consequences for our planet will be catastrophic.
