A team of international scientists, led by astronomers from Cardiff University, has shown for the first time that galaxies can change their structure over the course of their lifetime. The researchers have shown that a large proportion of galaxies have undergone a major ‘metamorphosis’ since they were initially formed after the Big Bang.
An international team of astronomers studying more than 200,000 galaxies has made the most comprehensive assessment of the energy output of the nearby universe. The Galaxy And Mass Assembly (GAMA) project confirms that the energy produced is only about half what it was two billion years ago and this fading is occurring across all wavelengths from the ultraviolet to the far infrared. The universe is slowly dying.
