The star could be as old as 14.5 billion years (plus or minus 0.8 billion years), which at first glance would make it older than the universe's calculated age of about 13.8 billion years, an obvious dilemma. Among stars found in the Milky Way, it has the lowest iron level ever measured. The oldest star so far, is HE 1523-0901. It is about 13 billion years old and was discovered using the Curtis Schmidt telescope at the Cerro Tololo Inter-American Observatory in Chile. Astronomers now say the honor may go to HD 140283, a gassy giant that's celebrated an estimated 13.2 billion birthdays, give or take a couple hundred million, according to the January 2013 issue of Nature. 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. While all Population II stars are metal-poor, this star is considered extremely metal-poor.

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). Image credit: Space Telescope Science Institute/AAP A team led by astronomers at The Australian National University has discovered the oldest known star … The Big Bang, which occurred about 13.8 billion years ago, is considered the beginning of the universe. The newfound star is not only one of the oldest stars in the universe, but also one of the most metal-poor stars known. 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. Only after millions of years, namely 400-500, the first body was lit. An explosion of high-energy radiation may have been spotted coming from a galaxy in the distant universe. It is located about 6,000 light-years away from Earth. She then used a technique similar to the carbon-14 method, which is used to date archaeological finds, to determine the age of HE1523-0901. New research shows that star cluster HP1 (seen here through Chile’s Gemini South telescope) may contain some of the oldest stars in the Milky Way, dating to roughly 12.8 billion years old. This means that like other old stars, it formed not long after the beginning of the universe. The star’s age, as measured by ESO’s Very Large Telescope, is 13.2 billion years. The star's age, as measured by ESO's Very Large Telescope, is 13.2 billion years. Once a star goes supernova, the explosion sends its elements across the universe, making them the building blocks of new star formations. The star’s estimated age is about 13.2 billion years. Which is our universe's oldest star? HE 1523-0901 is the first star whose age was determine… Age:  13.2 billion years If confirmed, it would be the oldest known gamma-ray … That makes it the oldest object ever observed. Approximately 190 light years from Earth is a star that's estimated to be 14.46 billion years old. Called the Methuselah star, HD 140283 is 190.1 light-years away. NASA Found the Oldest Molecules in the Universe SMSS J160540.18-144323.1's tell is its iron levels. 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: (Image: © The Australia National University) Astronomers have found what appears to be one of … We can never really be sure what is the oldest star in the Universe but Methuselah Star is widely seen as being the oldest star so far discovered. As telescope technology advances, the title for oldest star will change and scientists hope that they will soon be able to find the first stars of the universe. Distance from Earth: 15,300 light years This was the first time that researchers used thorium and uranium with three other elements europium, osmium, and iridium to successfully figure out a star’s age. The star is made almost entirely out of helium and hydrogen, with an extremely low amount of other chemical elements. Distance from Earth: 6,000 light years These are recognized as among the oldest: Some of these are among the first stars from reionization (the stellar dawn), ending the Dark Ages (cosmology) about 370,000 years after Big Bang. But earlier estimates from observations dating back to 2000 placed the star as old as 16 billion years. Age:  ~14.5 ± 0.8 billion years (at least 13.2 billion years) Your email address will not be published. Distance from Earth: ~4,140 light years It is 12.91 billion years old and started to form about 800 million years after the Big Bang. Due to its age, studies of HD 140283 helps scientists learn more about the early universe. Methuselah Star, the Oldest Known Star in the Universe. Constellation:  Aquarius. Its low heavy metal content was first noticed in 1963 and for over two decades HD 122563 was the most metal-poor star known. Globular star clusters are some of the most ancient objects in the entire Universe, like Messier 56, above. Save my name, email, and website in this browser for the next time I comment. According To the Big Bang Theory, our universe came into existence nearly 13.8 billion years ago. GN-z11 is currently the oldest and most distant known galaxy in the observable universe. 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. Your email address will not be published. New research shows that star cluster HP1 (seen here through Chile’s Gemini South telescope) may contain some of the oldest stars in the Milky Way, dating to roughly 12.8 billion years old. Distance from Earth: ~7,500 light years STAR older than the Universe | METHUSELAH Star (HD 140283) | Oldest Star in The Universe Star older than the universe discovered that may prove big Bang Theory wrong!!! [8], Please expand the article to include this information. This Digitized Sky Survey image shows the oldest star with a well-determined age in our galaxy. And while the newfound 13.7-billion-year-old star is currently the oldest known in the universe, there may be other second-generation stars out there. Elisabetta Caffau and her team had been looking for extremely metal-poor stars for over a decade before they discovered this one. These ancient stars, which are all Population II stars, are nearly as old as the universe. Like SciShow? Age:  13 billion years 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. She and her team hope to find other similar stars in the future. It is widely accepted that the Universeis about 13.8 billion years old give or take a million or so. Let me remind you that supernova is a phenomenon in which the brightness of the massive star increases by 4-8 orders of magnitude, after which there is a slow fade. In 2002, a group of scientists discovered that BD +17° 3248 had gold, marking the first time that gold had been discovered in a star other than our Sun. It was already old when the Sun was just starting to fuse hydrogen into helium. This star formed so early in our Universe’s history, was most likely a second-generation star. Determining the ages…. Astronomers may have found the coldest star in the universe, a brown dwarf 75 light years from Earth. Its composition has been crucial in understanding galactic chemical evolution. 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. An artist’s concept of a small red dwarf star is shown above. The star’s age is estimated to be about 13.8 billion years with an uncertainty of 4 billion years. Approximately 190 light years from Earth is a star that's estimated to be 14.46 billion years old. A team led by astronomers at The Australian National University has discovered the oldest known star in the Universe, which formed shortly after the Big Bang 13.7 billion years ago.

The researchers said that while every star probably has trace amounts of gold, this was the first time that they were able to confirm the element’s existence. And, if accurate, it would also mean that the star is older than the universe itself—currently estimated to be 13.82 billion years Type:  Unknown Above: A full-sky map of the oldest light in the universe.Colors indicate "warmer" (red) and "cooler" (blue) spots. 200 million years after the Big Bang, the very first stars (called Population III stars) began to form, researchers discovered seven new neutron-capture elements in HD 122563, Frebel used the ESO’s VLT to measure the abundance of the radioactive elements uranium and thorium in HE 1523-0901, a group of scientists discovered that BD +17° 3248 had gold, star could be as old as 14.5 billion years. Around 2005, researchers discovered seven new neutron-capture elements in HD 122563: Niobium, Molybdenum, Ruthenium, Palladium, Silver, Praseodymium, and Samarium. The measurement uncertaintyin the age estimate is 0.7 to 2.7 billion years, depending upon the assumptions made to estimate the uncertainty, although the uncertainty in the relative age of this and other stars using the same method is smaller. Oldest Star (Source: Google images, illustrative) After the Big Bang, the first stars started to form from the heating hydrogen gas roughly 13.7 billion years ago. Previously, the title of oldest known star in the universe was held by HD 140283, which is about 13.2 billion years old. And, if accurate, it would also mean that the star is older than the universe Now, a team of astronomers led by Stefan Keller of The Australian National University have discovered one of the first stars.
