interferometer are distributed across different continents of the Earth, and it will be able to see the birth of the first stars in the universe and notice the possible existence of life's distant radar on the exoplanet working.
The Future SKA-Low Antenna: Artist’s Impression
square kilometers array (SKA ) has been in development for about 30 years, and it was not until now that Australia began to build its “Phase I”—an array of more than 100,000 SKA-Low Antennas. Scientists say future instruments are one of the largest scientific projects of the century. It will give you an idea of the earliest universes, in the age when the first stars light up and the first galaxies emerge, and perhaps it also helps in the search for alien civilizations. The press release of the international consortium SKA organization describes this.
SKA is a radio interferometer consisting of many antennas as spaced as possible and acts as a single telescope with high resolution. The first part of the tool will be the SKA-Low array, which began construction in Western Australia a year later. It will include 131,072 tree antennas for detecting low-frequency radio signals. The second phase will be the nearly 200 SKA-Mid dish antenna arrays located in South Africa. SKA is headquartered in University of Manchester .
Africa SKA-Mid antenna: Artist perspective
This instrument is expected to allow the study of distant pulsar —a fast-rotating neutron star as a source of radiation and gravitational waves, in order to perform the next test of general relativity . Its ability to see the most distant objects will help to better understand the origins and evolution of the first galaxies, and even study the cosmic "dark ages" before the first galaxies appeared.
In addition, members of the SKA organization alliance pointed out that the sensitivity of the interferometer "will enable us to detect radars at planetary airports near stars tens of light years from Earth" or " cell phones in astronauts' pockets on Mars ", 225 million kilometers. ” This makes SKA a promising tool for finding possible signals for extraterrestrial civilizations.
