Venus does not have a magnetic field, so it would not have night-time aurora such as the ones we see. Instead, solar wind particles penetrate deep into the upper atmosphere where they can collide with carbon dioxide and traces of oxygen.

We now know that aurorae appear, in one form or another, on each major planet of the Solar System (bar Mercury) as well as some of Jupiter’s moons. The aurorae of Jupiter and Saturn are complex and powerful, while on Mars and Venus they’re very weak.

The planets that we know experience Auroras in our solar system are the gas giants: Jupiter, Saturn, Uranus and Neptune.

auroras on many different planets. On Earth, Jupiter, Saturn, Uranus, and Neptune, solar wind (charged particles flowing from the Sun) interacts with planetary magnetic fields to create auroras. On Mars and Venus, auroras come from solar wind interacting with the atmosphere.

Today Mars has no visible aurora, but it does have ultraviolet aurora. These are known as proton aurora, and they occur with the solar wind strikes hydrogen atoms in the upper atmosphere of Mars.

Uranus is not just a featureless ball of bluish-green gas. Bright auroras light up the planet’s atmosphere in two newly released photos, which combine observations by NASA’s Hubble Space Telescope and the agency’s Voyager 2 probe.

Uranus is blue-green in color, as a result of the methane in its mostly hydrogen-helium atmosphere. The planet is often dubbed an ice giant, since at least 80% of its mass is a fluid mix of water, methane and ammonia ice. That’s because Uranus has little to no internal heat to supplement the heat from the sun.

Much like on Earth, auroras on Jupiter are linked to charged particles within the planet’s magnetosphere. However, Jupiter’s magnetosphere is about 20,000 times stronger than Earth’s, which means the gas giant can deflect incoming solar winds from up to 4 million miles (6 million km) away.

Saturn’s auroral displays are caused by an energetic wind from the Sun that sweeps over the planet, much like the Earth’s aurora that is occasionally seen in the nighttime sky and similar to the phenomenon that causes fluorescent lamps to glow.

Authentic aurora photos from space NASA has a spacecraft orbiting Earth to watch and measure the aurora, and astronauts on the International Space Station can see them from the same distance, CBC reported.

While the curtain-like auroras we see at Earth are green at the bottom and red at the top, NASA’s Cassini spacecraft has shown us similar curtain-like auroras at Saturn that are red at the bottom and purple at the top. This is how the auroras would look to the human eye.
