In order to ''see'' deep space in more detail, Mitsubishi Electric focused its energy on a high-precision radio telescope

Astronomy: it's the oldest science in the world and, at the same time, the most cutting-edge.

Astronomy is known as the oldest science in the world, but it is also the newest. Beginning with the naked eye in ancient times, observation methods have advanced with the appearance of the first telescope and the current radio telescope. The radio telescope uses the slight electromagnetic waves, not visible light, originating from celestial bodies to clarify the appearance of space. Electromagnetic waves from space were first discerned in the 1930s, and it is no exaggeration to say that astronomy has centered on the radio telescope ever since. In 1981, Mitsubishi Electric delivered a radio telescope to Tokyo Observatory in Nobeyama, Nagano Prefecture. Even more than 20 years later, this telescope boasts the highest level of performance in the world. But many difficulties had to be surmounted before it became operational.
