[ Watch the Video: How Have Barred Spiral Galaxies Evolved Over Time? ] John P. Millis, PhD for redOrbit.com - Your Universe Online There are a number of interesting puzzles in astronomy that have faced significant challenge because the analysis simply requires massive amounts of data and complicated algorithms that demands serious computing power. Luckily, in at least some of these cases, the same algorithms that are a difficult for a computer to execute are relatively easy for our...

Scientists Study 'Galaxy Zoo' Using Google Maps An Thousands Of Volunteers

The reddest galaxies with the largest central bulb show the largest bars -gigantic central columns of stars and dark matter-, according to a scientific study that used Google Maps to observe the sky. A group of volunteers of more than 200,000 participants of the galaxy classification project Galaxy Zoo contributed to this research. More than two thirds of spiral galaxies, including our own Milky Way, display a central bar that can extend for thousands of light years. These colossal...

With the help of the army of volunteers working on the Galaxy Zoo 2 "Ëœcitizen science' project, an international team of scientists have discovered that the bars found in many spiral galaxies could be helping to kill them off. The researchers present their results in the journal Monthly Notices of the Royal Astronomical Society. The overwhelming majority of stars in the universe are found in galaxies like our own Milky Way. These vast stellar assemblies contain anything between a...

Researchers have observed the signs of distant dwarf galaxies being swallowed up by spiral galaxies, and their findings "could shed further light on the evolution of galaxies," according to BBC News. A team of researchers, led by David Martinez-Delgado of Germany's Max Planck Institute for Astronomy (MPIA), noted that the dwarf galaxies that are being absorbed tend to form vine-like structures and long strands of stars known as stellar streams that are produced due to tidal forces. While the...

Astronomers at The University of Nottingham have identified a type of galaxy that could be the missing link in our understanding of galaxy evolution. The STAGES study led by the University's Centre for Astronomy and Particle Theory examines galaxy evolution using images from the Hubble Space Telescope. A separate project "” Galaxy Zoo "” uses volunteers from the general public to classify galaxies. Both teams have identified a population of unusual red spiral galaxies that are...

Astronomers at Liverpool John Moores University may have solved the mystery of how spiral galaxies in clusters are transformed over time into smooth disks.  Results from a study of galaxy clusters confirm that the slow-motion conditions needed for the transformation are occurring among populations of galaxies falling towards the cluster centre. Over the past several billion years the predominant shape of disc galaxies in clusters has changed from a spiral to a smooth disk. Theory...
