A rainbow may have shattered a world record of being the longest lasting after gracing the sky above Taiwan for nine hours.
Students and professors from the Chinese Culture University in Tapei's mountains recorded the rainbow, which appeared in the sky for eight hours and 58 minutes, reports the BBC.
The current world record is a rainbow that lasted for six hours in Yorkshire, England, according to the Guinness World Records.
"It was amazing… It felt like a gift from the sky... It's so rare!" said Chou Kun-hsuan, a professor at the University.
"After four hours, we mobilised all our students and began to notify everyone in the school to take pictures and send us pictures.
"When we broke the previous record after passing six hours, I was hardly able to stay seated for lunch; it was around lunchtime.
"I was so excited; I wanted to make sure we captured the rainbow. But then it did something even more incredible; it went on to beat the previous record by another three hours!"
The university is currently gathering its data and evidence to apply for the Guinness record.
The crew of a Cathay Pacific flight saw what it believes was North Korea's latest missile test last week, the second airline to report sighting it.
Cathay said Monday (local time) that the flight from San Francisco to Hong Kong reported witnessing the apparent re-entry of the ICBM that North Korea launched before dawn Wednesday (local time).
The missile was far from the plane, and operation was unaffected, Cathay said, adding that it had informed other carriers and relevant authorities.
"At the moment, no one is changing any routes or operating parameters," the Hong Kong-based airline said in a statement. "We remain alert and (will) review the situation as it evolves."
The North Korean missile was fired very high up, reaching an altitude of 4,475 kilometres before falling back into the Sea of Japan about 950 kilometres from where it was launched. It was in the air for 53 minutes.
The Hwasong-15 intercontinental ballistic missile demonstrated a greater range than other missiles North Korea has tested.
One expert estimated its range at more than 13,000 kilometres if launched on a standard trajectory, which would put Washington, D.C., within reach.
Korean Air pilots on two different planes also reported seeing flashes of light believed to be the North Korean missile when they were flying over Japan, airline spokesman Cho Hyun-mook said.
The flights, one from San Francisco and the other from Los Angeles, were both headed for Incheon, the main airport serving Seoul, South Korea.
Experts say the chance of a missile test hitting a civilian airliner is very low. North Korea likely chooses splashdown points for each stage that avoid airline routes, said Vipin Narang, an expert on nuclear strategy at the Massachusetts Institute of Technology.
"The problem is if the test goes awry in any way, and debris starts falling in ... more heavily trafficked areas," he said in an email. "That would still be low probability but more risky."
