The video is broadly correct that auroras occur on several planets, but it simplifies how they form on Mars and Uranus/Neptune and slightly overstates some details.
Claim-by-claim breakdown
Accurate (81% confidence): Most planets in the solar system have auroras in some form. NASA notes that auroras can occur on other planets and moons with atmospheres, and official NASA pages document auroras on Jupiter, Saturn, Mars, Uranus, and Neptune.
Accurate (97% confidence): Jupiter's auroras are produced by particles coming from Io's volcanic activity rather than only from the Sun. NASA says Jupiter's auroras are caused by particles spewed out by volcanoes on Io, which are then magnetically funneled into Jupiter's atmosphere. Solar particles also contribute, but Io is a major source.
Accurate (95% confidence): Saturn has auroras, and they are mainly observed in ultraviolet light from space. NASA states Saturn's auroras can be seen only in ultraviolet light and are visible only from space using ultraviolet-sensitive instruments.
Accurate (86% confidence): Mars has weak, patchy auroras because it lacks a strong global magnetic field. NASA describes Mars as having no global magnetic field and identifies patchy proton auroras associated with crustal magnetic fields and solar-wind conditions.
Accurate (89% confidence): Uranus and Neptune have auroras, but they are not located at the poles in the same way as Earth's auroras because their magnetic fields are tilted and offset. NASA says Uranus's auroras are not in line with the poles because of its lopsided magnetic field, and NASA's Neptune coverage describes its magnetic field as strongly tilted and offset.
Accurate (96% confidence): Uranus is tilted by about 90 degrees relative to its orbit around the Sun. NASA describes Uranus as tipped nearly on its side, with an axial tilt of about 98 degrees.
Misleading (78% confidence): On Uranus and Neptune, auroras appear near the equator rather than at the poles. NASA sources emphasize tilted and offset magnetic fields and unusual auroral geometry, but do not reduce the phenomenon to a simple equatorial ring.
