  Researchers at the University of California, Santa Cruz have used a supercomputer to create a spiral galaxy that matches our own Milky Way galaxy. The computer simulation is part of a physics project involving galaxy formation and evolution. "Previous efforts to form a massive disk galaxy like the Milky Way had failed, because the simulated galaxies ended up with huge central bulges compared to the size of the disk," Javiera Guedes, a graduate student in astronomy and...

Rare Blob Unveiled: Evidence for Hydrogen Gas Falling onto a Dark Matter Clump? ESO's VLT has helped scientists to discover a large primordial 'blob', more than 10 billion light-years away. The most likely scenario to account for its existence and properties is that it represents the early stage in the formation of a galaxy, when gas falls onto a large clump of dark matter. Over the last few years, astronomers have discovered in the distant Universe a few so-called 'blobs'. These are rather...

RAS -- Scientists from the University of Durham may have solved a decades-old puzzle regarding the distribution of the eleven small satellite galaxies that surround the Milky Way. The Milky Way is not alone. It is surrounded by a retinue of small "dwarf galaxy" companions. Cosmological theory predicts that these galaxies should occupy a large, nearly spherical halo but observations show that the satellite galaxies have a bizarre flattened, pancake-like distribution. The Durham team used...
