NASA spacecraft detects a constant ‘hum’ deep in the cosmos

This entry was posted in Space Administration on by .

Beyond the edge of the solar system, more than 14 billion miles from Earth, a NASA spacecraft has detected a curious and persistent “hum” in interstellar space.

The faint but constant vibrations were picked up by the Voyager 1 spacecraft, which, after more than four decades journeying deep into the cosmos, is the most distant human-made object in space. Scientists say the new discovery, published Monday in the journal Nature Astronomy, is providing a unique and never-before-seen glimpse of the interstellar environment ‘ the frontier beyond the reaches of the sun and planets in our cosmic neighborhood.

Quite a lot has been going on:

NASA spacecraft detects a constant ‘hum’ deep in the cosmos

“Voyager 1 is in an interesting region of space that is outside this thing called the heliosphere, which is the protective bubble that encases all the planets in the solar system,” said Stella Ocker, a doctoral student at Cornell University in Ithaca, New York, and one of the authors of the new study. “So, it’s really our only tool for directly sampling the nature of interstellar space.”

Ocker and her colleagues don’t yet know what’s causing the “hum,” but it was measured through ripples of plasma in what’s known as the interstellar medium, the hodgepodge of gas, radiation and particles that make up the space between stars. While it’s not an actual audio signal, the faint drone showed up as vibrations in a narrow frequency bandwidth, Ocker said.

NASA probe Voyager 1 detects constant hum in interstellar space

Although signals from the machine travel at the speed of light, they still take more than 21 hours to reach Earth from Voyager 1.

Scientists examining the data have noticed a constant hum in the deep interstellar space Voyager 1 currently resides in.

Having passed the edge of the heliopause in 2012, Voyager 1 is now unprotected against the winds of plasma, which its Plasma Wave System has detected.

Senior author James Cordes, the George Feldstein Professor of Astronomy, said: “The interstellar medium is like a quiet or gentle rain.

“In the case of a solar outburst, it’s like detecting a lightning burst in a thunderstorm and then it’s back to a gentle rain.”
