Scientists looking over old data on Uranus discover something new
Uranus is very far from the sun, making it one of the coldest planets in our solar system. Over 30 years ago, Voyager 2 flew by the planet on January 24, 1986. Decades later, scientists were looking over that data again and found another new secret about the planet. What scientists didn’t know 34 years ago was that Voyager 2 had flown through a plasmoid, which is a giant magnetic bubble that scientists believe could have been stripping Uranus of its atmosphere. Scientists say that atmospheric escape is driven by the magnetic field of the planet that can help the atmospheric escape or hinder the process. Magnetic fields are believed to help protect the planet by fending off atmosphere-stripping blasts from the solar wind. However, these magnetic fields can also create opportunities for the atmosphere to escape. Both Jupiter and Saturn suffer from this condition where significant amounts of atmosphere escape when magnetic field lines become tangled. Scientists say that Ur
