"Some of the dominant colors seen in aurorae are red, a hue produced by the nitrogen molecules, and green, which is produced by oxygen molecules." "Every type of atom or molecule, whether it's atomic hydrogen or a molecule like carbon dioxide, absorbs and radiates its own unique set of colors, which is analogous to how every human being has a unique set of fingerprints," Teets told. The bright colors of the northern lights are dictated by the chemical composition of Earth's atmosphere. "These particles are deflected towards the poles of Earth by our planet's magnetic field and interact with our atmosphere, depositing energy and causing the atmosphere to fluoresce," said Billy Teets, an astronomer and the director of Dyer Observatory at Vanderbilt University in Nashville, Tennessee. In the Northern Hemisphere, the phenomenon is called the northern lights (aurora borealis), while in the Southern Hemisphere, it's called the southern lights (aurora australis). When that wind slams into Earth's ionosphere, or upper atmosphere, the aurora is born.

Auroras, on the other hand, are created when charged particles from the sun ionize or excite particles in the atmosphere. Beneath the northern lights is a blanket of marmalade-colored airglow, a type of luminescence caused by ultraviolet light that triggers chemical reactions high in Earth's atmosphere. 22, the station was orbiting 261 miles (420 kilometers) above the Atlantic Ocean off the coast of North America. The actor and the barrister married in September 2014 before welcoming their children in 2017.A vibrant, green aurora lights up Earth's upper atmosphere in this photo captured by an astronaut at the International Space Station. “Then I knew from the minute I met her that everything was going to be different,” he said, before revealing that the couple ultimately decided to have children after they’d been married for a year. However, according to Clooney, that changed “when this extraordinary human being walked into my life and I just fell madly in love”. Speaking with Marc Maron on the WTF with Marc Maron podcast, Clooney recalled: “Listen, I didn’t want to get married. The actor’s candid comments about parenthood come after he recently opened up about realising he wanted to become a father only after meeting Amal. “Apparently, you have to wash your children every once in a while.” “I’ll tell you what I’ve taken on as a hobby: two or three loads of laundry a day, dishes all f***ing day, because these kids are all slobs,” he said.
