| Space: The final frontier in silicon chemistry Posted: 11 Nov 2014 08:11 AM PST Silicon, which is one of the most common elements in Earth's crust, is also sprinkled abundantly throughout interstellar space. The only way to identify silicon-containing molecules in the far corners of the cosmos – and to understand the chemistry that created them – is to observe through telescopes the electromagnetic radiation the molecules emit. |
| Best evidence yet for galactic merger in distant protocluster Posted: 10 Nov 2014 01:10 PM PST Nestled among a triplet of young galaxies more than 12.5 billion light-years away is a cosmic powerhouse: a galaxy that is producing stars nearly 1,000 times faster than our own Milky Way. This energetic starburst galaxy, known as AzTEC-3, together with its gang of calmer galaxies may represent the best evidence yet that large galaxies grow from the merger of smaller ones in the early Universe, a process known as hierarchical merging. |
| Baby photos of a scaled-up solar system Posted: 10 Nov 2014 12:09 PM PST Astronomers have discovered two dust belts surrounded by a large dust halo around young star HD 95086. The findings provide a look back at what our solar system may have resembled in its infancy. |
