The most man-made thing in the universe is the Voyager probes, which were launched in the 1970s. The probes darted through our solar system and eventually moved into interstellar space beyond, and in a remarkable engineering feat, even though they are over forty However, they are still working and collecting important scientific data, according to digital trends.
Recently, researchers examining data from Voyager 1 found a deep and continuous hum, and researchers from Cornell University determined that the buzz was due to the presence of interstellar gas small amounts of hydrogen and helium present between the star systems that form the building blocks of new stars.
Researcher Stella Koch-Auker said, It's very faint and monotonous in color because it's in a narrow frequency range.
The resonance was captured using Voyager's plasma-wave system, which was used in the past to detect changes in interstellar gas caused by solar winds from the sun, but it has now become clear that these relatively dramatic eruptions occur against a background of constant resonance.
Lead author James Cordes said, The interstellar medium is like a calm or gentle rain. In the event of a solar eruption, it is like detecting a lightning burst in a thunderstorm and then returning to light rain.
And the fact that researchers were able to detect the incoming humming of interstellar gas could indicate that the gas is more energetic than previously thought. By watching it closely, researchers can identify how it is affected by solar activity. This could be useful for understanding space weather here in our Solar system.
It's a testament to the amazing Voyager spacecraft even long-established instruments can still provide important data. Scientifically, this research is a remarkable achievement.” It is the engineering gift of science that keeps giving.
