The works for the largest radio telescope in the world have been completed

On July 3rd, 2016 the construction of the largest radiotelescope in the world has been completed.  FAST (Five-hundred-meter-Aperture Spherical radio Telescope) was built in China and its concept was first proposed in 1994, but because of the logistical setbacks of finding an appropriate site for the enormous dish, the construction works...

A fast-burst-finding upgrade for the Europe’s biggest radiotelescope

The Effelsberg radio dish at the Max Planck Institute for Radioastronomy in Bonn, is one of the world’s largest fully-steerable radiotelescopes. It will be upgraded using a technology developed by Australia’s Commonwealth Scientific and Industrial Research Organization. A new Phased Array Feed (PAF), currently under testing and calibration, will be set to...

Radio telescopes: the astronomical observation is reaching very high levels of quality

Today radio telescopes have achieved a higher resolution and have more abilities to discern fine detail. The astronomical observation is reaching very high levels of quality. Astronomers promise to advance the understanding of quasars, supermassive black holes at the cores of galaxies. A lot of achievements were obtained by scientists’ conjunction of the Russian...

The LOFAR radio telescope expands into Ireland

LOFAR (Low-Frequency Array for Radio astronomy) is the largest connected radio telescope in the world: there are 50 stations in the network spread across six partner countries, with 38 in the Netherlands, six in Germany, three in Poland, and one each in France, Sweden, and Britain. This year a LOFAR station will...

The Sardinia Radio Telescope

The Sardinia Radio Telescope is the largest radio telescope and the most technologically advanced in Italy. It originated from a collaboration between National Institute for Astrophysics (INAF), Italian Space Agency (ASI) and Sardinia Region; it costs approximately 70 million of euros and it is located near San Basilio, province of Cagliari. Completed in 2011,...

Upgrade of the India’s biggest radio telescope

GMRT, the India’s biggest radio-telescope, is used by astronomers from across the world for frontline research in astronomy and astrophysics. In operation since 2002, GMRT is an array of 30 fully steerable, 45 metre diameter antennas, spread out over a 30 km region near Narayangaon. Recently this telescope has been upgraded to...

China: assembly begins of “FAST”, the largest radio telescope in the world

FAST radio telescope assembly has begun in China. The name is an indication of the size: Five-hundred-meter Aperture Spherical radio Telescope. With its 500 meters in diameter, covering an area of about 30 football fields, FAST will exceed the Puerto Rican Arecibo Observatory, currently the largest radio telescope ever built, by...

RadioAstron: four years after going into orbit the first important results arrive

The first important results are arriving from RadioAstron, the Russian space radio telescope that was sent into orbit on 18 July 2011 from the Baikonur base in Kazakhstan. Working in combination with terrestrial antennae in radio interferometric mode on an extremely long base, called VLBI, RadioAstron has collected radio signals...
