On September 1 197.7, Voyager 1 was launched into space to travel to Jupiter and Saturn, before the stars moved forward. 2012 – NASA’s robotic explorer leaves the solar system and arrives at Heliopos.
Now, a little research focused on the galaxy heard by fake space shows that this ignored signal can tell a great deal about the void outside our solar system.
Voyager 1 It is now 22.5 billion kilometers (114 billion miles) away from the Earth and is spreading through a mixture of particles and gases called interstellar medium. This gun, recorded since 2017, is believed to be the result of plasma waves in this cosmic soup.
“It’s very faint and monotone, because it’s in a narrow frequency bandwidth. We’re detecting faint, constant hue of interstellar gas,” explains. Stella Coach Oker, A doctoral student in astronomy at Cornell University.
The waves? Time for maritime peace! What? They pass – already?
Two years later, Voyager 1 was encountered Jupiter 1 1979. in, and three years later Saturday. After the NASA spacecraft crossed the heliopause (a solar-powered magnetic bubble) in August 2012, it was traveling at more than 600,000 kph (38,000 MPH).
The inland medium – a soup of particles and radiation – is often portrayed as calm and ruthless – but now it seems like a misconception. Like the oceans on Earth, the contents are found to be filled with medium waves.
The largest of these waves has come from the rotating effect of our galaxy, causing swells to spread light for years as space degrades itself. Supernova Produce small (albeit large) waves, while pushing through heliopause, solar eruptions from our own sun are responsible for the smallest induction.
These waves could tell astronomers about the density of the international medium. Their energy vibrates at specific frequencies depending on the density of the electrons Electrons around the spacecraft. The higher frequency reveals the presence of higher density within the terrestrial matrix.
“Interstellar medium is like a calm or gentle rain. Solar eruptions are like detecting an electrical explosion in a rock and then returning to light rain, ”explains James Cordes, a professor of astronomy at Kernel.
Study waves have its ups and downs
Long-distance travelers to the star have now spent eight years in zero exploration among the stars. Gradually, astronomers and astronomers have come up with new ideas about space. Voyager spacecraft.
“The Voyager 1 plasma wave system has estimated the plasma density at approximately 0 ounces of interstellar space, and it reveals a large density gradient and turbulence outside the heliopause,” the researchers wrote in the journal Nature Astronomy.
After crossing over Interstellar space, Plasma Wave System Equipment Voyager 1 The ship recorded changes in the interstitial medium due to the impact of our distant star.
Even now, however, the NASA spacecraft is close to the heliosphere, which is the result of the “waves” in the ocean that the spacecraft felt as a result of solar effects. Although moving forward as a spacecraft The sun, The influence of other stars will be more prominent.
“We have some ideas about how far Voyager can go to start seeing pure water, so let’s talk. But we don’t know when we’ll get to that point.” Oker describes.
This new study represents (possibly) the first continuous measurement of interstellar content. Researchers suggest that low-level disturbances in plasma waves may be higher than expected, allowing the study of these disturbances for the first time over a longer period.
Previous studies have relied on waiting for the sun to affect these outer boundaries Solar system, Providing the opportunity to watch the waves through the interstellar medium.
“V’Ger must evolve. This knowledge has reached the limits of this universe and it must evolve. What is its need for God, Doctor, is the answer to the question, ‘Is there nothing else?’ “- Commander Spoke, Star Trek: The Motion Picture
Investigators found this lone, unconscious signal – a plasma wave emission, like a single note that changes over time – recorded Voyager By measuring changes in pitch over several years, it was possible to map the density of the international medium through which Voyager 1 passed.
They found that the density of the interstellar medium around Vogeser 1 increased by 1,000,000% between 2013 and 2001, reaching the current reading in 201.
“What the sun isn’t doing, Voyager is sending back the details. The craft is saying, ‘Here’s the density I’m swimming in right now. And it’s now. And it’s now. And it’s now.” Voyager is far away and it’s continuing, “Colonel research scientist Shami Chatterjee describes.
Astronomers hope the discovery will help them learn more about how the interleaved medium interacts with the heliosphere – the protective layer of charged particles. The edge of our family of planets Which protects our solar system from the rays of the galactic universe.
If, by some strange coincidence, an alien genius encounters Voyager in the distant future either (in a strange-please-don’t-do-this-sequel twist) Star Trek: The Motion Picture), They find the message in a bottle. Each spacecraft is equipped with a golden record, presenting the view and sound of the earth. This message to the stars was made in the minds of famous astronomers Carl Sagan.
The Voyager spacecraft continued to make progress in science for more than a decade for the underlying international journey of their marathon mission.
