construction square kilometer array observatory be the best scheduled to start Next month, after the project spent seven years in the design and engineering phase, When finished, the SKA Observatory will be the largest. radio telescope On a planet with a collection area to cover more than a kilometer.
Here’s a little more information about the project from SKA organization myself:
SKA stands for Square Kilometer Array. This reflects the original desire to create a telescope with a total surface of one square kilometer through antennas spread over long distances. The idea for the SKA dates back to the early 1990s, and although The original name will remain But the scientific, conceptual and engineering goals behind the project have evolved over the years. As a result, the current scientific requirement includes 130,000 antennas and 200 dishes. Formerly known as SKA1, the two arrays composed of SKA have a combined area of nearly half a square kilometer. Since the antenna can be added to the interferometer, future expansion of the SKA will allow this further collection area.
So it’s a big event. That may be why construction is expected to be completed in July. of 2029According to the report of economic situationThis makes sense because the construction of the SKA Observatory was a work spanning two sites on two continents.
One site will be in South Africa, where the SKA will consist of 197 satellite dishes collecting mid-frequency data. Another site is for Western Australia, where about 131,000 Christmas tree-shaped antennas collect low-frequency data.
The SKA Observatory requires both sites to function. This is because recording data from both sites and combining them is how scientists create images from these radio telescope installations. FT:
Many objects in space emit electromagnetic radiation with wavelengths much longer than the visible light.The clarity and intensity of the signal depends on the chemical and physical processes occurring within each object. By combining the signal received from a tree-shaped low-frequency antenna in Australia and a mid-frequency dish receiver in South Africa, the SKA covers an unprecedented wavelength range. Powerful data processing can convert signals into images.
As you can guess, the project will take almost $2.4 billion in tons of cash. But it seems space (like sports) is one of those things that can still unite countries and their governments, for example. FT Details:

but other countries will also benefit from the installation. And such arrays are expected to be operational for fifty years.
The SKA Observatory will allow astronomers to detect other civilizations. that emitted radio waves for the first time report:
For the first time, astronomers will be able to “Detects radio emissions from planets associated with nearby stars that are comparable to those caused by human activity on Earth. This opens the possibility of detecting other technology-based civilizations in our galaxy,” said SKA designers.
“Search for extraterrestrial intelligence [known in science circles as Seti] It’s not one of our main scientific missions. But if we find it, ‘wow,’” Diamond said, “we’ll be the best Seti machine in the world.”
So no, the SKA Observatory is not intended for technical search. smart lifeBut it certainly won’t hurt the search either.
