The telescopes involved in the successful detection of fringes during a VLBI test experiment were part of the European VLBI Network (EVN) and included: Badary Radio Astronomical Observatory (Institute of Applied Astronomy, Russia), Effelsberg Radio Telescope (Max-Planck Institute for Radio Astronomy, Germany), Hartebeesthoek Radio Astronomy Observatory (National Research Foundation, South Africa), Jodrell Bank Observatory (University of Manchester, UK), Medicina Radio Observatory (National Institute for Astrophysics, Italy), Onsala Space Observatory (Chalmers University of Technology, Sweden), Svetloe Radio Astronomical Observatory (Institute of Applied Astronomy, Russia), Toruń Centre for Astronomy (Nicolaus Copernicus University, Poland), Ürümqi Astronomical Observatory (Chinese Academy of Sciences, China), Ventspils International Radio Astronomy Centre (Latvian Academy of Sciences, Latvia), Westerbork Synthesis Radio Telescope (ASTRON, the Netherlands), Yebes Observatory (National Geographic Institute, Spain), and Zelenchukskaya Observatory (Institute of Applied Astronomy, Russia).
The ability to “see” fine detail in sources depends on the ratio of the size of the telescope to the radio wavelength, and in order to make this as good as possible a method known as aperture synthesis was developed at Cambridge. The principle behind this method is that we use several smaller aerials, linked together, and record the signals as the aerials are moved relative to each other by moving the aerials along a rail track and by the rotation of the Earth. The computer then takes all of the data and synthesises a map with as high resolution as we would obtain if we were able to build a much larger dish. This method has been adopted at observatories around the world, and extended to include telescopes operating on different continents or even on satellites.
Utmost - The Molonglo Observatory Synthesis Telescope
Now, thanks to the extensive upgrade of the Molonglo Observatory Synthesis Telescope (MOST), located about 350 km south of Parkes near Canberra, there is a definitive answer. In a paper in , a research team from Australian National University, Swinburne University of Technology, University of Sydney and the ARC Centre of Excellence for All-sky Astrophysics (CAASTRO), has confirmed the FRBs do in fact originate from outer space and – in some cases, at least – from galaxies beyond the Milky Way.

The Westerbork Synthesis Radio Telescope is one of the most powerful radio observatories in the world. It enables astronomers to study a wide range of astrophysical problems: from pulsars to kinematics of nearby galaxies to the physics of black-holes.

Ghana is the first partner country of the African Very Long Baseline Interferometer (VLBI) Network (AVN) to complete the conversion of a communications antenna into a functioning radio telescope. The 32-metre converted telecommunications antenna at the Ghana Intelsat Satellite Earth Station at Kutunse will be integrated into the African VLBI Network (AVN) in preparation for the second phase construction of the Square Kilometre Array (SKA) across the African continent. The combination ‘first light’ science observations included Methanol Maser detections, VLBI fringe testing and Pulsar observations. Reaching these three objectives confirm that the instrument can operate as a single dish radio telescope and also as part of global VLBI network observations, such as the European VLBI network. Following the initial ‘first light’ observations, the research teams from Ghana and South Africa together with other international research partners, continue to do more observations and are analysing the data generated with the aim to characterise the system and improve its accuracy for future experiments.

“The Ghanaian government warmly embraces the prospect of radio astronomy in the country and our radio astronomy development plan forms part of the broader Ghana Science, Technology and Innovation Development Plan,” says Professor Kwabena Frimpong-Boateng, the Ghana Minister of Environment, Science, Technology and Innovation (MESTI). As an SKA Africa partner country, Ghana welcomed and collaborated with the SKA South Africa (SKA SA)/HartRAO (Hartebeesthoek Radio Astronomy Observatory) group to harness the radio astronomy potential of the redundant satellite communication antenna at Kutunse. A team of scientists and engineers from SKA SA/HartRAO and the Ghana Space Science and Technology Institute (GSSTI) which is under MESTI, has been working since 2011 on the astronomy instrument upgrade to make it radio-astronomy ready. In 2012, Ghana launched the GSSTI as the vehicle through which to grow its astro-physics programme.
