Understand

Traditional radio telescopes use large, steel dishes to observe radio sources.

The LOFAR radio telescope is different, and uses tens of thousands of fixed, non-movable antennas instead, a novel design that promises ground-breaking research in astronomy.
The antennas observe omnidirectionally, and sky sources are observed by signal-processing techniques that combine the data from all antennas.
Another new feature of LOFAR is the elaborate use of software to do signal processing in real time, where traditional telescopes use custom-built hardware.
