Tinuku Breakthrough Listen reports 11 significant signals of extraterrestrial civilization

The Breakthrough Initiatives project was launched in 2015 using Green Bank Telescope 100 meters in West Virginia, the 2.4-meter Automated Planet Finder optical telescope at Lick Observatory, 64-meter Parkes Telescope in Australia, and future plans to incorporate other large telescopes around the world Obtain multiple petabytes of data.

A $ 100 million search is the beginning of Breakthrough Listen supported by billionaire Yuri Milner and a group of scientists including Stephen Hawking. The ambitious project aims to find civilizations in the 1 million stars closest to the Sun and 100 galaxies closest to the Milky Way.

The program also includes a Breakthrough Starshot aimed at developing a transportation system to send sailing nano satellites that move to another star system by traveling 20 percent the speed of light using a laser power boost.

Scientists design and build an analytical path that scans through billions of radio channels to look for unique signals from extraterrestrial civilizations. The basics look for signature technologies beyond the earth using a simple method.

Signals from artificial and natural processes differ in features such as bandwidth thickness, irregular spectral behavior, pulse or modulation, and other unusual characteristics. The algorithm is designed to ensure that the signal comes from a fixed point relative to the star or other target being observed, and not from the local interferer.

"We were able to identify possibilities due to radio frequency interference," said Andrew Siemion, astrophysicist and Berkeley Director of SETI Research Center, a presentation at the Breakthrough Discuss conference.



"The first scientific results from Breakthrough Listen are now available to the world for review.The search has not detected a convincing signal for the existence of space intelligence, these are the early days," said Andrew Siemion.

The scientists sort data from 692 stars consisting of three observations in 5 minutes per star, interspersed with observations 5 minutes from a set of secondary targets. The star samples determined by two selection criteria are stars in 16 light years from the Sun and stars with 163 light-years.

"The sample of stars we call the spectral type, we want to see as many different types of stars as possible, we must be open to all the possibilities that life can emerge between these stars," Siemion said.

Observations targeting a group of frequencies are called "waterholes" or a quiet part of the radio spectrum that translates as a good point of interstellar communication. Hole is located between the hydroxyl and hydrogen molecular emission bands.

"This result is the most comprehensive and fundamental test of the water hole hypothesis ever undertaken for nearby stars, a classic idea in search of the intelligence of extraterrestrials that have existed for more than four decades," Siemion said.

Eleven events above the threshold have significant importance that requires further detailed analysis and ensures that they come from an artificial space source. Unusual signals are:

1. HIP 17147 (HD 22879), F-type star about 83 light years.

2. HIP 4436 (Mu Andromedae or HD 5448), A-type star about 130 light years from Earth. Twice the mass of Sun, 2.4 times the radius of Sun and about 600 million years old.

3. HIP 66704 (HD 119124), star F-type.

4. HIP 99427, variable star.

5. HIP 39826 (BD+21 1764), binary or dual binary system.

6. HIP 20901 (79 Tau or b Tau or HD 28355), A-type star 160 light years from Earth. Member of Hyades star cluster.

7. HIP 82860 (19 Dra or h Dra or HD 153597), a binary star in the Draco constellation.

8. HIP 74981 (BD + 29 2654), K-type star.

9. HIP 65352 (HD 116442), G-type star.

10. HIP 45493 (18 Uma or e UMa or HD 79439), variable star Delta Scuti type about 160 light years from Earth.

11. HIP 7981 (107 Psc or HD 10476), the main K-type star about 24 light-years from Earth, about 6 billion years old, has 83% mass and 80% radius of Sun.
