'Solar Tsunami' Confirms Voyager 1 In Interstellar Space
Δημοσιεύτηκε στις 9 Ιουλ 2014
NASA
has announced that the Voyager 1 spacecraft, first launched in 1977,
has reached interstellar space. Voyager 1 reportedly left the
heliosphere of particles and magnetic fields around the sun in 2012, and
now measurements taken by the Voyager 1 after solar eruptions show that
it has traveled to another cosmic realm where our solar system thins
out.
Based on new data, NASA has received further confirmation that the Voyager 1 spacecraft has reached interstellar space.
Voyager
1 reportedly left the heliosphere of particles and magnetic fields
around the sun in 2012, and now measurements taken by the Voyager 1
after solar eruptions show that it has traveled to another cosmic realm.
By
measuring the vibrations from two coronal mass ejections and the
cruising speed of the spacecraft, scientists were able to calculate the
position of the Voyager 1.
Data from a third solar eruption has
confirmed the results of the previous calculations, which placed the
spacecraft outside of the heliosphere.
Don Gurnett of the
University of Iowa who serves as the principal investigator of Voyager
1's plasma wave instrument, is quoted as saying: "All is not quiet
around Voyager. We're excited to analyze these new data. So far, we can
say that it confirms we are in interstellar space."
A video from NASA shows the vibrations recorded by Voyager 1 that were sent back to Earth as sound.
The
Voyager 1 was launched in September 1977. Even though it travels at
about 1 million miles a day, it's taken it nearly 37 years to reach this
far.
