A new method of analysis will allow a census of quasars

Over the past six decades have passed since the time when the first quasars were discovered that the list of high-galaxies with their fixture - a black hole at the galactic center filled with more than 100,000 objects.

However, attempts to produce a thorough census of powerful radiation sources have so far been restricted to one fundamental problem. The fact that extreme brightness of quasars, allowing them to see from a great distance, at the same time playing on them, 

ALMA telescope expose ancient galaxies at record speed

The team of astronomers used the new telescope ALMA (Atacama Large Millimeter / submillimeter Array), to discover the location of more than a hundred galaxies with the most active star formation in the early universe. ALMA telescope is so powerful that just a few hours, he made ​​many observations of distant galaxies, as has been done like all other telescopes around the world for more than a decade.

At a go off star discovered disk of debris and dust

Herschel Space Observatory of the European Space Agency released the first pictures of the belt of dust - formed as a result of collisions of asteroids or comets - orbiting star-subgiant, which is located around the planetary system.

After a few billion years, during which the stars stably maintained hydrogen is burning stars like our sun, draining internal resources and
