Construction has begun on a massive telescope called the Square Kilometre Array (SKA). When built it will be the largest radio telescope in the world.
The amazing device is split across a total of 16 countries including South Africa Australia. It includes more than 100,000 antennas which will be built as part of the project.
The $3 billion construction will take around six years to build, and is expected to be completed in 2028.
As a first step, the site in Australia will work alongside a project in South Africa that has 197 satellite dishes.
The first major milestone should come in 2024, when four dishes in Australia and six antenna stations in South Africa are made to work together.
The technology within the new telescope will mean scientists will be able to detect very faint radio signals coming billions of light-years from Earth.
