Here are some advancements in SETI, or the Search for Extraterrestrial Intelligence: 

• Optical experiments: Some SETI researchers believe that alien civilizations might use lasers for interstellar communications at optical wavelengths. Several optical SETI experiments are currently in progress. 
• Radio spectrum: Most SETI sky searches have studied the radio spectrum

Here are some achievements of the SETI Institute: 

• Fieldwork SETI scientists conducted fieldwork in Antarctica, Chile, Alaska, and the High Arctic. 
• Telescopes SETI scientists observed the universe through telescopes at the Arecibo Observatory, the Green Bank Telescope, SOFIA, and the Hubble Space Telescope.

The Allen Telescope Array (ATA) is a group of 42 antennas, each 6 meters in diameter, that can operate as a single large dish or as 42 independent dishes. The ATA can operate over multiple frequency bands concurrently

The ATA has a log-periodic feed that covers the entire range of frequencies from 500 megahertz (MHz) to 11.2 GHz. When the signals from all 350 antennas are combined in one set of processing systems, the array is transformed into sixteen virtual telescopes, each with the sensitivity of a 114-meter diameter antenna and the resolving power of a 900-meter antenna. 

The ATA can be used for both SETI and radio astronomy research. It offers SETI scientists access to an instrument seven days a week, and permits the search of several different targets simultaneously. This can result in a speed-up of SETI searches by a factor of at least 100

The search for extraterrestrial intelligence(SETI) is a collective term for scientific searches for intelligent extraterrestrial life, for example, monitoring electromagnetic radiationfor signs of transmissions from civilizations on other planets.

Scientific investigation began shortly after the advent of radio in the early 1900s, and focused international efforts have been ongoing since the 1980s.^[4] In 2015, Stephen Hawking and Israeli billionaire Yuri Milner announced the Breakthrough Listen Project, a $100 million 10-year attempt to detect signals from nearby stars.^{( source google)}

SETI Institute’s Center for SETI Research (CSR) uses ATA in the search for extraterrestrial intelligence, observing 12 hours a day, 7 days a week. From 2007 to 2015, ATA identified hundreds of millions of technological signals. So far, all these signals have been assigned the status of noise or radio frequency interference because a) they appear to be generated by satellites or Earth-based transmitters, or b) they disappeared before the threshold time limit of ~1 hour.Researchers in CSR are working on ways to reduce the threshold time limit, and to expand ATA’s capabilities for detection of signals that may have embedded messages.^{[source google)}

Breakthrough listening program ( SETI)

The Breakthrough Listen project is a scientific research program that searches for evidence of civilizations beyond Earth. The project began in July 2015 and has a budget of $100 million. It uses 13 telescopes and involves 50 researchers from institutions around the world. 

The project searches for technosignatures, which are signs of technology that may have been developed by extraterrestrial intelligence. The program includes a survey of the 1,000,000 closest stars to Earth. One of the first targets observed was Proxima Centauri, which appears to host two small rocky planets in the star’s habitable zone. 

The Breakthrough Listen project has helped transform the search for extraterrestrial intelligence (SETI) into a rigorous scientific field

The Breakthrough Listen project uses a variety of techniques to search for technosignatures, including: 

• Radio and optical bands: The project surveys a wide range of radio and optical bands. The radio telescopes are sensitive enough to detect “Earth-leakage” levels of radio transmission from stars within 5 parsecs. 
• Optical wavelengths: The project uses facilities such as the Automated Planet Finder to search for laser emission lines present in stellar spectra. 
• Data processing: The project uses cutting-edge data processing to analyze petabytes of data across billions of frequency channels. 
• Artificial intelligence (AI): The project uses AI to detect signals. 
• Targeting and scheduling software: The project uses sophisticated targeting and scheduling software. 
• Automated data processing pipeline: The project uses an automated data processing pipeline that scours information from MeerKAT in real time to hunt for interesting or unusual signals. 

The project uses some of the world’s most powerful instruments, which are 50 times more sensitive than existing telescopes dedicated to the search for intelligence.

Scientists achieved a breakthrough in the Doppler shift phenomenon, which could help the Search for Extraterrestrial Intelligence (SETI) detect alien radio signals

The META spectrum analyzer uses frequency Doppler shift to distinguish between signals of terrestrial and extraterrestrial origin.  The Doppler effect is named after Christian Doppler, who wrote about it in 1842. For sound waves, an ambulance siren is a common example. As the ambulance siren is moving toward an observer, the observer perceives a higher pitch sound, and then they perceive a lower pitch when the siren is moving away. 

The Doppler effect has important applications in the fields of astronomy and space technology. For example, Edwin Hubble made the discovery that the universe expands as a consequence of the Doppler Effect
