Voyager 1 spacecraft ‘hum’ finds deep space

Toronto – NASA’s Voyager 1 spacecraft launched 44 years ago is now the most man-made distant object in space – and it has sent back some new discoveries from the edge of our solar system.

At a speed of about 61,152 kilometers per hour, Voyager 1 flew through Jupiter in 1979 and then into Saturn in the late 1980s, now known as the boundary of the solar system, the boundary of the solar system with galaxy space, and the galaxy.

A new study led by Cornell University and published in the journal Nature Astronomy shows how Voyager 1’s instruments detect “fixed drones of galaxy” or plasma waves. According to a publication.

The data, which was sent back from a distance of more than 22.5 billion kilometers, allowed researchers to find the “hum”.

“It’s very dizzy and monotonous because it’s on a short frequency band,” Cornell PhD astronomy student Stella Koch Ocker said in a statement. “We are detecting the faint, constant ohm of the galaxy.”

Voyager 1’s data allow researchers to understand how the galaxy interacts with the solar wind and how the heliosphere’s defense bubble in our solar system is designed and modified by its deep space environment.

After entering the galaxy, Voyager 1’s “plasma wave system” detected disturbances in the gas, but between them – they are caused by the sun – the researchers were able to find a stable, continuous sound. Location. ”

“The galaxy is like a calm or gentle rain,” said George Fordstein, a senior author and astronomy professor. “In the case of a solar flare, it’s like detecting a thunderstorm, and then it returns to a gentle shower.”

Ocker believes there is less activity in the galaxy than previously thought, and new data will allow researchers to monitor the spatial distribution of the Plasma Voyager 1 mission.
