Step 1 : Introduction to the question "What is the nickname given to the oldest known star in the universe?"
...Astronomers have found what appears to be one of the oldest known stars in the universe. The ancient star formed not long after the Big Bang 13.8 billion years ago, according to Australian National University scientists. Ancient Star May Be Oldest in Known Universe -oldest-st... More results What is the oldest planet in the universe? Despite being mostly gas by bulk, it's more than 300 times the mass of Earth. For that reason astronomers suspect the planet was the oldest, able to scoop up more material out of the disk before its younger siblings appeared. The new study supports the idea of a firstborn Jupiter.
Step 2 : Answer to the question "What is the nickname given to the oldest known star in the universe?"
HD 140283 is 190.1 light-years away from Earth. Called the "Methuselah" star, astronomers have determined the age of the star is between 13.7 billion years and 14.5 billion years old. The problem this presents for astronomers is this calculation puts Methuselah as potentially older than the calculated age of the universe. Most researchers set the Big Bang, which created the universe, as occurring about 13.8 billion years ago. Research teams use the Hubble Space Telescope to study the Methuselah star as it passes through Earth's region of the galaxy. Source: Space.com
