| It's filamentary: How galaxies evolve in the cosmic web Posted: 20 Nov 2014 10:34 AM PST How do galaxies like our Milky Way form, and just how do they evolve? Are galaxies affected by their surrounding environment? Astronomers now propose some answers. The researchers highlight the role of the 'cosmic web' -- a large-scale web-like structure comprised of galaxies -- on the evolution of galaxies that took place in the distant universe, a few billion years after the Big Bang. |
| Riddle of the missing stars: Hubble observations cast further doubt on how globular clusters formed Posted: 20 Nov 2014 08:32 AM PST Thanks to the NASA/ESA Hubble Space Telescope, some of the most mysterious cosmic residents have just become even more puzzling. New observations of globular clusters in a small galaxy show they are very similar to those found in the Milky Way, and so must have formed in a similar way. |
| NASA's Swift mission probes an exotic object: 'Kicked' black hole or mega star? Posted: 19 Nov 2014 02:50 PM PST Astronomers have discovered an unusual source of light in a galaxy some 90 million light-years away. The dwarf galaxy Markarian 177 (center) and its unusual source SDSS1133 (blue) lie 90 million light-years away. The galaxies are located in the bowl of the Big Dipper, a well-known star pattern in the constellation Ursa Major. |
