Expressing its eyes, surrounding the antique star system, the most complete Einstein ring so far!

In the shocking Hubble telescope image, scientists accurately determine the age of the "melting ring"

From a new science of the 2020 Hubble telescope image, it illuminates a story behind the shining aura.

This ring is also known as Einstein Ring, named after predicting the name of the famous physicist. Its emergence is due to the illusion of galaxy. The galaxy around this "melting ring" is called GAL-CLUS-022058S, which is located in the Southern Hemisphere Galaxy (FORNAX) and the heavenly furnace seat.

Just as scientists belonging to the Hubble Space Telescope wrote in a statement, this giant ring is actually pollution caused by the lens effect. When a foreground object with a strong gravity enlarge the light of the galaxy behind it, the lens effect will produce. The new research shows that the galaxy in this halo we see was what it looked like 9 billion years ago, that is, the age of the universe was only about one -third of its 13.8 billion years old.

A picture from the Hubble Telescope shows one of the most complete Einstein rings that scientists have studied so far.

Nicholas Suerzar, a member of the Max Plank Institute for Radio Astronomy from Max Plank Institute for Radio Astronomy, Germany, members of the European Astronaut The announcement of the statement said: "The detection of molecular gases that bred a new star enables us to calculate accurate red shifts, so we believe that we are really observing a very distant galaxy." NASA) is cooperating to carry out the Hubble telescope project.

The statement of this Hubble telescope wrote: "At that time, the universe was experiencing a" baby tide "and formed thousands of stars at a very high yield. A glance at a close distance from the distance. "

As early as this photo was just released in 2020, scientists claimed that this was one of the most complete Einstein rings in all the catalogs so far. After the picture was publicly published, astronomers excavated the archives collected by the large telescope of the large telescope (the EUROPEAN SOUTHERN OBSERVATORY), which calculated the distance of 9.4 billion light years. Further analysis enables the research team to carefully investigate the star material groups in the lens effect galaxy and make a reminder for its evolution.

Hubble Telescope officials said in the same statement: "Among the most shiny and extremely dusty early galaxies, the rate of star formation is extremely high, which is 1,000 times faster than the occurrence rate in our own galaxy. This phenomenon may be possible. It helps to explain the high -speed formation of the giant ellipse group today. "

The original Hubble Telescope Observation task was carried out by Saurabh JHA of New Jersey's Saurabh Jha of Rutgers, The State University of New Jersey, and from the Universidad Politécnica De Cartagena) Anastasio díaz-sánchez served as chief investigator in the new study of the galaxy.

The Einstein ring refers to a phenomenon that the light source is affected by the optical lens effect due to the light source, which changes the shape of the light source obtained from the observation.
