The journal Nature published an article detailing new data from Voyager 2, which was 8.3 billion miles away from the Sun, traveling at speeds faster than 34,000 miles per hour (6,437.38 kilometers per hour). Studying Voyager 2’s newest data, a team led by Merav Opher of George Mason University in Fairfax, Virginia, found that the galaxy’s magnetic field is approximately twice as strong as scientists had expected to find beyond Earth’s solar system, as well as unexpectedly tilted. The team’s study results revealed that the galaxy’s magnetic field is tilted 30 degrees out of alignment with its disc, whereas scientists had previously believed that the two were perfectly aligned.
