The twin Voyager of NASA has made another outstanding discovery in interstellar space. The space vehicle identified a new electron burst mechanism, which will explain the phenomena of stars flaring according to the agency’s research reports. These bursts transpired after cosmic-ray electrons deep in the solar system are accelerated by the shock waves emerging from solar eruptions. The research team noted that the electrons traveled along the cosmic magnetic field lines at supersonic speed. 

Physics and astronomy professor at the University of Iowa, Don Gurnett, articulated that the concept of shock waves pushing atomic particles is not a new phenomenon. However, he noted that the phenomenon is happening in a new system, the interstellar space. This discovery is different since it was a record expected to happen in the solar wind in the previous research. 

The twin Voyager spacecraft have been operating in space for over four decades while sending feedback to Earth with the still good systems. This year, the spacecraft flew independently while undergoing repairs and maintenance for its radar communication network before connecting with the Earth’s communication center. 

The research team noted that the initiation process for the electron burst is coronal mass ejections. The solar eruptions release an enormous quantity of supercritical plasma in space, generating shock waves that travel in the solar system. The shock waves then propel the ray electrons, possibly coming from far-fetched parts of the solar system. These rays travel under cosmic magnetic field lines existing with the stars through interstellar space. 

The magnetic fields accelerate the cosmic rays at nearly the speed of light, which is over 600 times the impact of the shock waves. Researchers at the University of Iowa hypothesized that these electrons must be emerging from strong magnetic fields in the interstellar space before acquiring an additional force of the shock waves. The scientists explained that the cosmic rays might acquire more speed as the distance between them and the shock waves widens. 

The two Voyager vehicles examined the electron bursts and discovered that they accelerate for some days leaving lower energy plasma motion in the interstellar space. The scientists emphasized that the solar shock wave is in action for a year because the spacecraft is very far from the sun. 

To sum up, astronomers hope to utilize this data to explain the phenomenon of stars flaring. However, the scientists must be prepared to encounter solar outbursts, which are extremely dangerous for the spacecraft, the International Space Station, and any other payload roaming the entirety of space. For example, the solar eruptions pose a considerable danger to the satellites scavenging around Earth.
