Atop the volcanic peak, inside the Mauna Kea Observatory, a magnificent sign displaying the constellation Lyra suddenly flickered. "Oh no!" Esi cried out, pointing at the dying crimson star. Dr. Aris rushed over, tapping the glass tube as the brilliant red glow sputtered and vanished into darkness. "The main spectrometer relay is down," Dr. Aris sighed, looking at the now-dark instrument. "We needed that for tonight's observation."

"But why was it that specific fiery red color?" Esi asked, pulling out her notebook. "It wasn't painted red." Dr. Aris smiled. "It wasn't! The tube is filled with a special gas, and when we pass electricity through it, the gas itself glows." She explained that our air is a mix of many invisible gases, each one needing to be carefully separated to find the ones that shine.

"To understand that red glow, we have to go back to London in the 1890s," Dr. Aris began. "Scientists had just found a mysterious, lazy gas in the air called Argon. They suspected it was part of a whole new, undiscovered family of elements hiding in plain sight." Esi imagined the foggy streets and the gas-lit laboratories of a bygone era, a world full of unanswered questions.

"A Scottish chemist named Sir William Ramsay was determined to find the rest of this hidden family," Dr. Aris continued. "He was incredibly precise and built a machine to cool air until it turned into a liquid. Then, he planned to separate the liquid air drop by drop, hunting for new gases." Esi pictured him, a pioneer exploring the very air she breathed.

"He and his assistant, Morris Travers, worked for weeks in their London lab," Dr. Aris said softly. "It reminds me of what the scientist Marie Curie said: 'Nothing in life is to be feared, it is only to be understood.' Ramsay wasn't afraid of the unknown; he was excited to understand it." They carefully collected the first tiny bubble of gas that evaporated from the liquid air.

Ramsay connected the electrode, and a jolt of electricity shot through the tube. Instantly, the entire laboratory was flooded with a blindingly brilliant, crimson-red light. Travers wrote in his journal that "the blaze of crimson light from the tube told its own story and was a sight to dwell upon and never forget." They had discovered a new element: Neon, from the Greek word 'neos,' meaning 'new'.

"That discovery lit up the world!" Dr. Aris exclaimed. "An engineer named Georges Claude figured out how to make long, reliable neon tubes, and soon the streets of Paris and New York were blazing with colorful signs. What's amazing is that neon is super rare here on Earth, but it's the fifth most common element in the entire universe!"

Back in the observatory, Esi's eyes lit up. "So the gas in our sign is neon! It's not broken, the electricity just isn't getting to it." Dr. Aris nodded, opening a panel below the sign. "Exactly! Thanks to Ramsay, we know what to look for. Ah, here's the problem—a loose wire on the transformer."

"Do the other 'lazy' gases glow in different colors?" Esi asked as she sketched the sign in her notebook. "They sure do!" Dr. Aris confirmed, pointing to a large periodic table on the wall. "Argon glows pale blue, helium is a peachy-pink, and krypton shines with a ghostly white light. It's a whole secret rainbow, hiding in the air all around us."

"Wow," Esi whispered, looking from her notebook to the glowing red sign, now shining steadily. "So a whole family of invisible gases can create a rainbow when you give them energy." Dr. Aris smiled and pointed out the window at the smoking volcano. "The Earth has its own energy too. But what makes it so incredibly hot deep inside our planet?"
