26 June 2019 –


The Next Generation Very Large Array (ngVLA) and Square Kilometre Array (SKA) projects are currently investigating a process to establish a scientific alliance that may result in an exchange of observing time across an unprecedented suite of cutting-edge telescopes spanning more than 3 orders of magnitude in observing frequency (50MHz – 116 GHz)

Such an alliance will yield unparalleled capabilities for investigating the most pressing astrophysical problems of our time, including the formation and evolution of the Universe, galaxies, stars and planets. While many details about the nature of any such scientific alliance remain to be resolved, both Observatories agreed they should be ambitious in exploring the possibilities of this type of arrangement in future.

After a productive initial meeting, we look forward to continuing the alliance discussions and meeting again in approximately 18 months, at which time SKA should have begun construction activities and ngVLA will be continuing design/development activities. One tangible outcome of the first meeting was an agreement to hold a joint SKA/ngVLA science meeting in 2021, details to be announced in due course.

About SKA

The Square Kilometre Arraywill be the world’s largest and most sensitive radio telescope. The total collecting area will be approximately one square kilometre giving 50 times the sensitivity, and 10 000 times the survey speed, of the best current-day telescopes. The SKA will be built in Southern Africa and in Australia. Thousands of receptors will extend to distances of 3 000 km from the central regions. The SKA will address fundamental unanswered questions about our Universe including how the first stars and galaxies formed after the Big Bang, how dark energy is accelerating the expansion of the Universe, the role of magnetism in the cosmos, the nature of gravity, and the search for life beyond Earth. Construction of phase one of the SKA is scheduled to start in 2016. The SKA Organisation, with its headquarters at Jodrell Bank Observatory, near Manchester, UK, was established in December 2011 as a not-for-profit company in order to formalise relationships between the international partners and centralise the leadership of the project.

The Square Kilometre Array (SKA) project is an international effort to build the world’s largest radio telescope, led by SKA Organisation. The SKA will conduct transformational science to improve our understanding of the Universe and the laws of fundamental physics, monitoring the sky in unprecedented detail and mapping it hundreds of times faster than any current facility.

Already supported by 10 member countries – Australia, Canada, China, India, Italy, New Zealand, South Africa, Sweden, The Netherlands and the United Kingdom – SKA Organisation has brought together some of the world’s finest scientists, engineers and policy makers and more than 100 companies and research institutions across 20 countries in the design and development of the telescope. Construction of the SKA is set to start in 2018, with early science observations in 2020.
