These include: what is the universe made of and how does it evolve? Are we alone in the universe? How do galaxies, stars and planets form and evolve? What are the laws of physics in extreme conditions? And how does the sun affect the earth? The University’s main role will be to search for signals which accompany the birth of stars.
Such an undertaking will require the completion of arrays of antennas to detect radio waves at metre-long wavelengths. The low frequencies of these waves gives rise to the telescope by the name of LOFAR – the LOw Frequency ARray. The arrays will be spread across the Netherlands, Germany, France and Great Britain.
The processing of the data will be done by a supercomputer situated at the University of Groningen and further radio telescopes may be constructed at sites in Poland, Sweden, Ireland and Ukraine.
Michael Smith, Professor of Astrophysics at the University of Kent, said: ‘The LOFAR project has been launched to advance upon instrumentation based on the old 1960s technologies of radio telescopes that used large mechanical dishes to collect signals which were then detected by a receiver for analysis.
‘Even if scientists continued to use the old technologies, the instruments for this project would need to be one hundred times larger than existing ones, which is cost prohibitive as a high proportion of the outlay on these telescopes is the steel and moving structure. Therefore, new technology was required to make the next step in sensitivity necessary to unravel the secrets of the early universe, the physical processes in the centres of galaxies, and the formation of quasars, stars and planets.’
LOFAR is the first telescope of this new sort, using an array of simple omni-directional antennas instead of mechanical signal processing with a dish. The electronic signals from the antennas are digitised, transported to a central digital processor, and combined in software to emulate a conventional antenna.

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
