Sent into space in 1990, the Hubble Space Telescope continues to reveal the surprises of the infinite universe with each discovery. Now, the telescope, hitherto discovered, the farthest star – or possibly the galaxy – reportedly discovered.

Officially called WHL0137-LS, but in Old English by the astronomers who discovered it “Morning Star” or “rising light” meaning Earendel the formation of the star, called the universe early It is said to date from his time. An article about the discovery published in Nature reveals much more interesting information about this ancient star.

8.2 billion years older than the Earth and the Sun

In the research article only after the big bang happened. 900 million years It’s exactly how the light emitted by the Earendel System, which is predicted to take the form it looks today, reaches Hubble. 12.8 billion years reportedly received. However, from the sun and the earth 8.2 billion years The galaxy, said to be older, is one of the first animal forms to exist on Earth. 12.1 billion years It is stated that he is older.

Moreover, Earendel stands out even among the old star standards known until now. Earendel is 9.4 billion years old, the oldest known star until this discovery. icarusIt is noteworthy that it is 3 billion years older than . But even the oldest supernovae, which are also easy to detect because they are usually the brightest objects in space, are more likely than Earendel. younger Is explained.

the galaxy where Earendel is located sunrise arch for Johns Hopkins University astronomer and lead author of the journal Nature, Brian Welch, “This galaxy appears to have been enlarged and stretched into a long thin crescent moon due to the gravitational lensing effect of a huge cluster of foreground galaxies” saves as.

Earendel may shed light on the early universe

The old star Earendel, which Welch and his team worked on for three and a half years to understand that it is a star team, history of the universe It is estimated that there may be a lot of new information about him. “With distant objects, we know the past of the universe and the universe more than we do today. it looks different we see a time Express as Welch, “We know that galaxies looked different in this early period, and we know that there have been relatively few generations of stars.” he adds.

Claiming that stars are “factories” of heavy elements in our universe, formed by the combination of lighter atoms like hydrogen and helium to form heavier substances like carbon, oxygen and even iron through nuclear fusion, Welch said Earendel was probably made of helium in its system at an early stage in the history of the universe. He also notes that it contains very few heavier materials. On the subject, Welch, “By studying this lensed star in detail, we were able to glimpse the stars at the outset. what do you look like and stars in the nearby universe how they are different opens a new window on passes the shape.

However, thanks to the James Webb Space Telescope, which will be operational soon, it is expected to understand whether Earendel is a single star system or a cluster of star systems. Whether Earendel is a single star or a binary system, temperature and mass It is believed that such information can also be learned.
