You will likely never forget seeing the northern lights if you've been lucky. There are green, red and purple ribbons of light that illuminate the night sky from the north to the south. There are similar lights in the southern hemisphere.
The ancient Greek goddess of dawn is thought to have inspired the name of the phenomenon. Solar winds bombarding Earth's upper atmosphere cause an Aurora. When solar winds interact with atmospheric gases, they light up in brilliant colors and are pulled into fantastic shapes on our planet's magnetic lines. James O'Donoghue is a planetary scientist at the Japanese Aeronautical Exploration Agency.
Is Earth the only place where you can see the Auroras?
Auroras are found on other bodies as well. Even more beautiful and exotic forms can be found in the extraterrestrial Auroras. The basic rules of planetary astronomy change when you look at other planets.
There is a question about the sunset on other planets.
Despite the fact that Mars has only patchy magnetic field lines, there is a recently discovered type of aurora on the Red Planet. According to research published in the journal Geophysical Research Letters, some Auroras are created by weather patterns. The magnetic field of the planet Uranus is tilted on its axis, causing it to have an effect on the Auroras. O'Donoghue said it was a mess.
Jupiter is the most powerful place in the solar system to see the Auroras. In a study published in the journal Nature, it was found that the bursts of radiation are up to 30 times stronger than on Earth. Most of Jupiter's light is outside of the visible spectrum, so you wouldn't be able to see it with your eyes. O'Donoghue said that visible light, X-rays, and radio are some of the things that can be seen on Jupiter andSaturn.
There is a breakdown in the definition of an Aurora. Normally, the light from the sun's wind is thought to be the source of the Auroras. Mercury has no atmosphere, but it does experience storms of the Northern lights. "If you look at Mercury's night side with an X-ray spectrometer, you can see the rock on the surface glowing with X-ray emissions." An X-ray spectrometer is used in astronomy.
Some of Jupiter'sAuroras are not produced by solar winds. According to NASA, they're generated by particles flung into the magnetosphere by the planet's volcanic Io.
Scientists hope that they will be able to peer far enough into the universe to detect the first Auroras on exoplanets with the next generation of instruments. It is certain that the light shows will be spectacular. "It's fascinating and strange and wonderful," Stallard said.
