The first implication is that the universe is filled with dust — much more dust than in the Milky Way and nearby galaxies.
«Dust is ubiquitous in nearby and more distant galaxies, but has, until recently, been very difficult to detect in the very early universe,» says University of Edinburgh astrophysicist Michal Michalowski, who was not involved in the study.
Astronomers working with the Sloan Digital Sky Survey have used a 2.5 - meter telescope at the Apache Point Observatory in Sunspot, New Mexico, to map the location of more than 930,000 nearby galaxies, determining the distance to each by how much the expansion of the universe has stretched, or «redshifted,» the wavelength of the galaxy's light.
The existence of such active galaxies in the nearby universe was first noted by the American astronomer Carl Seyfert more than 70 years ago.
Only when we look at galaxies billions of light - years away, collecting the light they emitted billions of years ago, can we see that the most distant galaxies are moving more slowly than we would expect from observations of nearby galaxies, an indication that the universe has since sped up.
