Extraterrestrial life is still a hot topic to talk about. Even u to 150 years human have been working on it to find the truth but ended up with no clues. It is hard to find the scientific proof that someone has tried so hard to call us. But, there were some unusual signals and sounds that researchers could not explain these things up to now.
10. Space and The Roar
If we believed that space was no life, there would be no sound. On the other hands, radio waves could travel through it. Many celestial objects could release the waves. For example, the Milky Way produced a hiss. It was in 2006, researchers launched their weather balloon from NASA’s Columbia Scientific Balloon Facility in Texas. The goal was to look for signs of the heat at the edge of the atmosphere. At that time, the heat changed into a vacuum environment at 120,000 feet.
Something strange happened. They heard a roar and this sound was six-time louder. Of course, it was beyond their expectation. The roar was from the universe. Up to now, researchers could not find the exact answer to how it happened, what was that and where it came from
9. The Sounds Of Moon Miranda
There are five months belongs to Uranus. The deepest moon called Miranda. In fact, Miranda has a strange shape and surface. Therefore, it is very popular as the “Frankenstein” moon. The reason is that it is like pieces that put together. For its size, it has 1/7 of the size of the moon belongs to Earth. But, Miranda has a canyon with 12 times deeper compared to the Grand Canyon. Voyager 2 caught the ambient and relaxed sound from there.
8. Jupiter And The Erie Sounds
Galileo, the NASA spacecraft was launched in 1989 with the commitment to study about the largest planet on the solar system, Jupiter. It was in June 1996 that the spacecraft flew to one of the Jupiter’s moons. This moon named Ganymede.
During this orbit, researchers worked together to collect the data and recreate the sound on Earth. They argued that the sound came from the charged particles around the moon. In addition, Voyager 1 has recorded three other recordings. Meanwhile, the Voyager 2 captured other sounds in the Magnetosphere, along with recording the lightning in the atmosphere.
7. Kepler Star Sounds
Researchers launched the Kepler space observatory in March 1999 with the goal to find the other planets that are as similar to Earth. The hope to find “another Earth” was so high at that time. During his journey, he recorded the data from the starlight curve. The curve showed a frequency of brightness variations that are so similar to the frequency of sound. In fact, the frequency is far from our capability to reach. Therefore, it is impossible for us to hear it. But, the presence of a mathematical technique known as Fourier analysis can help the researchers. They can increase the frequency so that human can hear it because it can meet our level.
6. The Radio Transmission SHGb02+14a
SETI @home is a project based on the Internet. It can take any information from Arecibo observatory and then puts the information on anyone’s computer. This project was launched in 1999 and it served as the screensaver to scan any information while looking for the signs of life.
The most promising signal this project could find was the Radio Transmission SHGb02+14a. It came in March 2003. They observed the source for three times at 1420 Megahertz (MHz). During the first set of this project, researchers used the 1420 MHz because chemicals could emit the signature electromagnetic frequencies. Other than that, 1420 MHz is the frequency signature if we are talking about hydrogen and it is the most common element in the universe.
They caught three signals from the area between the constellations Pisces and Aries. Interestingly, the nearest stars in this area are more than 1,000 light years away. So, if the signal was from there, of course, they have traveled a very long distance. Many people argued that it was just a technical error since all transmission was weak. The strange thing about the transmission was the way signal drifted. It was possible if the signal was from a planet that could rotate 40 times faster than the Earth. Up to now, the researchers are still not sure about this radio transmission, but it was the most popular signal from this project.
5. The Sounds Of Saturn
There was an unmanned spacecraft known as Cassini-Hugens. Researchers have sent the spacecraft to Saturn in 1997 and it became the first that could enter the ring of the planet. Later in 2002, Cassini has made 234 million miles away from Saturn. Then, the spacecraft detected the radio waves from the auroras around the poles of Saturn. The auroras are a little bit similar to the northern and southern lights on Earth. The sounds were so eerie and complex contained rising and falling tones with many changes in its frequency and time.
4. The X-Ray Signal
The study of using NASA’s Chandra X-Ray Observatory and another X-ray observatory named the European Space Agency’s XMM Newton, helped the researchers did unexplained discovery. What they have discovered was an unknown x-ray signal located in the Perseus galaxy cluster. It was still a big mystery. No one could tell about the cause of the signal. Astrophysicists believe that dark matter could make up 26% of the universe.
Also, they believed that the x-ray signal was from sterile neutrinos, the type of the hypothetical neutrino that could interact with the normal matter through gravity. Eventually, they believe that neutrinos could be the best way to explain the presence of the dark matter.
3. The Sound Of The Black Hole
A black hole can produce a sound. Edward Morgan from MIT could create the sound from the data he has collected from a black hole in the GRS 1915+105 star system. Researchers have found the star system in 1992 with the regular stars and a black hole.
2. The Sound Of The Explosion From Parkes Radio Telescope
During 2011 and 2012, the Parkes Radiotelescope in New South Wales, Australia detected four bursts of the radio signals. The burst could last for milliseconds but so powerful. In the past, there were similar radio bursts but no one could explain where it came from. In fact, the bursts were from much further away.
There were some arguments about the bursts. First, it could be the neutron stars that crashed each other. Second, it could be the evaporated black holes. The last was the gamma-ray bursts that involved the supernova.
1. The Bursts Of Arecibo Telescope Radio
We can say the case of the signals above could be because of the problem with Parkes telescope. It can be broken or it just picked up the radio signal from Earth. In fact, in November 2012, An Arecibo Telescope radio in Puerto Rico has detected one of the bursts. Of course, the bursts have traveled a very long distance so that it could arrive on Earth.
The researchers have made their calculations and they believe that the signals occurred about 10,000 times in a day. The bursts became the main reason why the astrophysicists are working to build the new telescope to find the fact why this radio signal is so frequent.Follow Us:
