5 Terrestrial Alien Mysterious Signals,
Lorimer erupted,
The so-called Lorimer eruption was discovered in 2007 when astronomers analyzed data captured by the Parks Radio Telescope.
The team found a period of October 2001, from billions of light-years away, lasting five milliseconds of high-brightness radio bursts, the data analysis table is the highest frequency signal, the first, which shows that the signal through the interstellar medium, has exceeded our galaxy, but this view was not accepted, but in 2013, the researchers claimed to have found four similar radio pulses,
Its source is 5-11 billion light-years away, and the energy generated is equivalent to the total amount of the sun for four months.
Its source is still unknown, but it is more necessary to travel at the speed of light to know that the original image should be in, or a high-density star such as a neutron star in a nearby quasar, or a super-flare from a magnetar.
Vanishing astronauts,
On April 12, 1961, Soviet cosmonaut Yuri, aboard the Manned Spacecraft Vostok, completed the flight around the earth, thus becoming the first human in history to enter space, and there is also a saying that Gagarin can only be regarded as the first surviving astronaut.
It is based on several missing and failed astronauts in space attempts, this statement originates from the radio receiver built by Judica, the Cordelia brothers, two Italian radio enthusiasts,
Two brothers were injured and overheard secret Soviet space operations, such as radio communications from female astronauts returning to the wreck, and a weak sos signal from a stranded spacecraft out of Earth's orbit, which gradually weakened as if the spacecraft were drifting away from Earth, and these happened in Gagarin, four months before the official flight.
The universe roars,
Attached to a balloon and released high into the sky to measure the tiny traces of heat emitted by the first generation of stars in the universe, this instrument called arcade (the absolute radiometer of physics and diffuse radiation for cosmic objects) detected a mysterious roar from the cosmic radio noise, a signal from the distant edge of the universe, which roared much louder than expected, and the measurements showed that its radio brightness was six times higher than the sum of all known radio signals in the universe.
Although astronomers have discharged known radio sources like outgoing stars and radio galaxies, the source of this signal is still unknown.
Radio power SHGB02+14A
In 2003, Seti astronomers, the Arecibo Radio Telescope, aimed the best candidate signals for two hundred extraterrestrial civilizations, and one of them disappeared, -SHGB02+14A.
The model was received three times near the frequency at 1420 MHz, the same as the main frequency of energy absorbed and emitted by hydrogen, and also a possible frequency for the existence of an alien broadcaster, the signal source is located between Pisces and Aries, and the STAR does not exist within 1000 light years of the SHGB02+14A round head, and the true source remains undiscovered.
WOW signal,
On August 15, 1977, the SETI project detected a strong narrow-band signal near the Sagittarius X Legion through the Big Ear Radio Telescope.
The discoverer of the signal, Jerry Eichmann, found all the signals found on the computer-printed file, and wrote wow on the edge of the page, each character on the file represents the intensity, from 0 to 35 signals, and the signals above the intensity nine are represented by letters, and after 72 seconds of observation, the signal reaches the highest intensity at the "U",
30 times the noise of the universe, the model is so compact, very close to the frequency of 1420 megahertz, which is therefore considered to be most likely emitted by principled extraterrestrial intelligence,
