Deep Space Network
The Deep Space Network (DSN) is a worldwide network of antennas that communicate with and track spacecraft in deep space. It is operated by NASA's Jet Propulsion Laboratory (JPL) and is used to receive data and commands from spacecraft, as well as to transmit commands to them.
The DSN is composed of three deep-space communications facilities located approximately 120 degrees apart around the world: at Goldstone, California (USA); Madrid, Spain; and Canberra, Australia. This allows for constant communication with spacecraft as the Earth rotates, and also provides backup in case of equipment failure at one of the sites.
The antennas at each DSN site are large, parabolic dishes that can capture weak signals from distant spacecraft. The largest antennas are 230 ft (70m) in diameter and can track a spacecraft as far as 12 billion miles (20 billion kilometers) away. The DSN also includes a variety of other equipment, such as signal processors and data recorders, that are used to process and store the data received from spacecraft.
The DSN is used to communicate with a wide variety of spacecraft, including the Voyager 1 and 2, the Mars rovers, and the Cassini-Huygens mission to Saturn. It also supports interplanetary missions that are currently in development, such as the Europa Clipper, a mission to study the icy moon of Jupiter and the Mars Sample Return mission.
One of the most important functions of DSN is to provide a continuous two-way communication with the spacecraft. This allows for real-time monitoring of the spacecraft's health and status, as well as for the transmission of commands to the spacecraft to adjust its course or perform specific tasks.

How Voyager communicate with Earth?
The Voyager spacecraft send radio signals to Earth using a device called a transceiver. The transceiver is a combination of a transmitter and a receiver that allows the spacecraft to both send and receive signals. The Voyager spacecraft use a high-gain antenna to transmit their radio signals back to Earth. The antenna is pointed in the direction of Earth and focuses the radio signals into a narrow beam, similar to a flashlight beam. This allows the spacecraft to send a strong signal to Earth despite the great distance between the spacecraft and Earth.
The signals are then received by NASA's Deep Space Network (DSN) antennas, which are located at three sites around the world (Goldstone, California; Madrid, Spain; and Canberra, Australia). These antennas are large, parabolic dishes that can capture the weak signals sent by the Voyager spacecraft from billions of miles away. Once received, the signals are amplified and sent to a data processing center where they are converted into a form that scientists can analyze.
The Voyager spacecraft also use a low-gain antenna as backup, and this antenna is used to send and receive less critical data like health status, and housekeeping data of the spacecraft.
Voyager 1 and 2 Data & Insights
It's worth noting that these are approximate values and may change slightly over time as the spacecraft continue their journey through space. Also, the Voyager spacecraft were built to last 5 years, but they have been operating for decades and still sending valuable data.
