Pebble-sized particles behind planet formation?

Astronomers have discovered that filaments of star-forming gas near the Orion Nebula may be brimming with pebble-sized particles.

ALMA telescope sizes up Pluto`s orbit

Scientists using a high-powered telescope in Chile have been able to measure Pluto`s orbit precisely, to help with navigation as a US probe nears the planet in 2015.

New radar images show unseen side of moon

Combined efforts of the two largest radio telescopes of their kind - the National Radio Astronomy Observatory`s Green Bank Telescope (GBT) in West Virginia and the Arecibo Observatory in Puerto Rico have produced images of Earth`s Moon that reveal more than can be seen with the naked eye.

Dwarf galaxies could help reveal supermassive black holes` origin

Astronomers have discovered more than 100 small, dwarf galaxies with characteristics indicating that they harbor massive black holes feeding on surrounding gas; this could help resolve the question as to how black holes originated and grew in the early universe.

Fresh supernova dust may help explain early galaxy formation

Researchers using Atacama Large Millimeter/submillimeter Array (ALMA) telescope have found a recent supernova that is brimming with freshly formed dust.

How binary stars are formed

Scientists, using the upgraded Karl G. Jansky Very Large Array (VLA), have discovered previously-unseen binary companions to a pair of very young protostars, which has now provided strong support for one of the competing explanations for how double-star systems form.
