The NASA Space Probe detected a ‘Persistent Hum’ deep in the Universe 14 billion miles from Earth.



NASA’s space probe is now deep in interstellar space and an interesting ‘hum’ constant detector.

Voyager 1, one of NASA’s two siblings, launched 44 years ago and is now the most distant man-made object in space – still in operation and zooms to Infinity.

The spacecraft has long zipped across the edge of the solar system, past the heliopause – the solar system’s border with interstellar space – into the interstellar medium.

An interstellar gas drone was detected. (Plasma waves) continues, according to research led by Cornell University.

A slow review of the data returned from more than 14 billion miles, Stella Koch Ocker, a Cornell PhD student in astronomy, revealed the emissions, “It was very faint and monotone because it was in the bandwidth. “We are detecting faint and continuous moans of interstellar gas.”

The work helps scientists understand how interstellar medium interacts with the solar wind, Ocker said, and how the solar system’s heliosphere defenses are shaped and modified by the interstellar environment.

Voyager 1 launched in September 1977, flew by Jupiter in 1979 and then Saturn in late 1980 traveled at 38,000 mph. Agent 1 skips heliopause in August 2012.

After entering interstellar space, the spacecraft’s Plasma Wave System detected a disturbance in the gas. But during those eruptions, which were caused by our own shining sun, researchers discovered a constant, persistent signature created by a slight near-vacuum, according to new research published in Natural astronomy.

“An interstellar medium is a calm or gentle rain,” said James Cordes, senior author, George Feldstein’s professor of astronomy. Thunderstorm then it will return again. “

Ocker believes there is a lower level of activity in interstellar gases than scientists previously thought, allowing researchers to track the spatial distribution of the plasma, that is, when it is undisturbed by solar flares.

Cornell research scientist Shami Chatterjee explains how important it is to continuously monitor interstellar space densities. “We never had a chance to assess it. We now know that we don’t need any incidental events involving the sun to measure interstellar plasma, ”Chatterjee said.

“Whatever the sun does, the Voyager sends details back. Yan is saying ‘This is the density I’m swimming at the moment. And this is now And this is now And this is now, ‘Voyager is quite remote and will continue to do so. “

Voyager 1 is out of Earth, holding a gold record created by a committee with the late Professor Cornell, Carl Sagan, as well as mid-1970s technology to transmit the signal to Earth.It takes 22 watts. According to NASA’s Jet Propulsion Laboratory, the craft had nearly 70 kilobytes of computer memory and at the start of the mission it had a data rate of 21 kilobits per second.

Due to the 14 billion miles of distance, the communication rate is slower to 160 bits per second, or about half the 300 baud rate.
