And the 13.5-billion-year-old star just so happens to reside right here in the Milky Way. The star is made almost entirely out of helium and hydrogen, with an extremely low amount of other chemical elements. Methuselah Star in the constellation of Libra is believed to be the oldest star in the universe, born soon after the creation of the Universe. Save my name, email, and website in this browser for the next time I comment. And, if accurate, it would also mean that the star is older than the universe Researchers say that the star could be as old as 14.5 billion years, but this would make it older than the calculated age of the universe, which is about 13.8 billion years old. It was already old when the Sun was just starting to fuse hydrogen into helium. These ancient stars, which are all Population II stars, are nearly as old as the universe. The age of the oldest known stars approaches the age of the universe, about 13.8 billion years.These are recognized as among the oldest: While Population III stars have yet to be detected by scientists, the oldest known stars that have been observed were born after the first stars went supernova. Astronomers find one of the oldest stars in the Universe The other star we've found so far has so little iron -- a key indicator that it was forged close to the dawn of the universe. Around 2005, researchers discovered seven new neutron-capture elements in HD 122563: Niobium, Molybdenum, Ruthenium, Palladium, Silver, Praseodymium, and Samarium. Type:  Subgiant Type:  Main sequence star Since about 1995, researchers led by Chris Sneden have found an abundance of 53 chemical elements in the star, which is second in number to the Sun. Type:  Subgiant Age:  13.2 billion years The star's age, as measured by ESO's Very Large Telescope, is 13.2 billion years. This makes it the oldest object yet discovered in the galaxy and nearly as old as the estimated age of the universe itself (13.7 billion years as measured by WMAP). Constellation:  Hercules. These trees, which only grow…, Spread the loveBonsai, which is the Japanese art of growing small trees in containers, dates back to about the 6th…, Spread the loveWhen it comes to the majesty of nature, mountains are some of the most prominent and awe-inspiring natural…, Spread the loveThe world’s deserts are some of largest, driest, hottest, and oldest places in the world. The oldest star in the Universe is possibly older than the universe itself This is a Digitized Sky Survey image of the oldest star with a well-determined age in our galaxy. In 2007, Anna Frebel used the European Southern Observatory (ESO)’s Very Large Telescope (VLT) to look for stars in our galaxy that were thought to be old. NASA Found the Oldest Molecules in the Universe SMSS J160540.18-144323.1's tell is its iron levels. The discovery of an ancient star formed approximately 13.6-billion years ago just after the Big Bang is telling us much about the early universe. The age of the oldest known stars approaches the age of the universe, about 13.8 billion years. Constellation:  Aquarius. Up until now, the oldest star that has had a reliable age measured for it is about 13.2 billion years old. However, recent calculations have lowered the star’s age to at least 13.2 billion years, which overlaps with the universe’s age. Astronomers refined the … If confirmed, it would be the oldest known gamma-ray … HD 122563 is unique among the other earliest known stars. About 200 million years after the Big Bang, the very first stars (called Population III stars) began to form. Distance from Earth: 6,000 light years BPS CS22892-0052, which is called Sneden’s Star after it’s lead observer Chris Sneden from the University of Texas at Austin, is another ancient star in the galactic halo of the Milky Way. 4 Oldest Bristlecone Pine Trees in the U.S. 10 Oldest Protected Areas in the United States, 10 Oldest Avengers in the Marvel Cinematic Universe.

Age:  13 billion years Hank tells the story of the mysterious star known as “Methuseleh,” and why scientists think that it is the oldest known star in the universe. Constellation:  Boötes. An explosion of high-energy radiation may have been spotted coming from a galaxy in the distant universe. Your email address will not be published. As part of new research, astronomers tried to find the oldest star. Age:  ~13 billion years Determining the ages….
