Voyager 1, which is the farthest human-made object from Earth and the primary to enter interstellar area, has been detecting a “faint, persistent hum” that scientists have attributed to interstellar gas.
James Cordes, a professor of astronomy at Cornell College, reportedly described the sound as a “quiet or mild rain.”
“Within the case of a photo voltaic outburst, it’s like detecting a lightning burst in a thunderstorm after which it’s again to a mild rain,” he stated.
Stella Koch Ocker, a doctoral scholar on the college, who lead the analysis, stated, “We’re detecting the faint, persistent hum of interstellar gasoline. It’s extremely faint and monotone, as a result of it’s in a slim frequency bandwidth.”
Voyager 1′s odyssey started in 1977 when the spacecraft and its twin, Voyager 2, had been launched on a tour of the gasoline large planets of the photo voltaic system.
After beaming again dazzling postcard views of Jupiter’s large pink spot and Saturn’s shimmering rings, Voyager 2 hopscotched to Uranus and Neptune. In the meantime, Voyager 1 used Saturn as a gravitational slingshot to energy itself previous Pluto.
It’s now about 15 billion miles from Earth.
Voyager 1 is in regards to the dimension of a subcompact automobile and carries devices that examine magnetic fields, cosmic rays and photo voltaic wind.
