It’s time to develop space tourism.
The Fermi Paradox and other cosmic theories about the habitability of the Universe will be confirmed. India’s Giant Metrewave Radio Telescope has picked up a radio signal from a galaxy far, far away.
It is called SDSSJ0826+5630 and is located at a distance of 8.8 billion light years. At the moment, this is a record distance from which it was possible to receive and process at least some signal.
In our case, humanity received the so-called neutral hydrogen radio link – a wave length in the range of 21 centimeters. The signal was received only because it was amplified 30 times by another galaxy, which acted as a lens. This phenomenon was proposed by Albert Einstein more than a century ago.
However, the signal did not bring too much. Scientists have deciphered that the source galaxy weighs 2 times more than the mass of its visible stars. But the main value of space communication is that it still passed – long-wave radio telescopes can be developed, and they will be able to receive even more of these signals. And there, who knows, maybe we will get information about extraterrestrial life.
The results of the study were published in the British journal Monthly Notices of the Royal Astronomical Society.
