What can LOFAR telescope do?

The revolutionary multi-beaming capabilities of the LOFAR telescope allow astronomers to engage in multiple lines of research at once: they can look back billions of years to a time before the first stars and galaxies were formed (the so-called ‘Dark Ages’), they can survey vast areas of the low-frequency radio sky.

What is radio telescope observation?

Radio telescopes are the main observing instrument used in radio astronomy, which studies the radio frequency portion of the electromagnetic spectrum emitted by astronomical objects, just as optical telescopes are the main observing instrument used in traditional optical astronomy which studies the light wave portion …

What is LOFAR sonar?

Active sonar systems emit the sound waves that are reflected from the controlled object. There are two basic methods used for passive sonar signal processing: LOFAR and DEMON analysis (LOFAR – Low-Frequency Analysis and Recording; DEMON – Demodulation of Envelope Modulation On Noise).

When was LOFAR built?

12 June 2010
By 2014, 38 stations in the Netherlands, five stations in Germany (Effelsberg, Tautenburg, Unterweilenbach, Bornim/Potsdam, and Jülich), and one each in the UK (Chilbolton), in France (Nançay) and in Sweden (Onsala) were operational. LOFAR was officially opened on 12 June 2010 by Queen Beatrix of the Netherlands.

Why was the radio telescope invented?

The radio telescope has come a long way from its humble origins back in 1931. The first attempt was designed by an amateur physicist named Karl Jansky, who all but stumbled upon the discovery of a radio antenna as something to be used for space research.

What is the resolution of a radio telescope?

To overcome this difficulty, radio astronomers use multiple radio telescopes at the same time, a technique called interferometry. This gives angular resolutions of 0.001″ or better by effectively creating a single telescope as large as the distance between the two farthest telescopes.

How do radio telescopes detect radio waves?

Here’s how it works: Two radio telescopes observe the same radio source. The telescopes are a known distance apart on the ground. The radio waves coming from the source will therefore arrive at one telescope at a slightly different time than the other.
