telescope Hubble arguably made one of his most important discoveries of all time with the discovery of the star Earendel, which is supposedly the furthest that humanity has ever seen. Second Sifi Wiresome researchers using the equipment found a star about 12.9 billion light-years away from uswith its light, which we see about 900 million years after the beginning of the universe.

If it is confirmed that the photographed object is indeed a star, it will easily surpass the previously set record. This is because the farthest star we have seen so far is MACS J1149+2223 Star with lens 1which was discovered in 2018 and its brightness dates back to when the universe was “only” 4 billion years old.

to find Earendel (in Portuguese: morning star) the explorers had to use gravitational lensing and gravity of galaxy clusters distort light. Thanks to this, it became possible to magnify objects that would not be possible in other ways, thanks to the cluster of galaxies. WHL0137-08 the light from the parent galaxy of the oldest observed star was distorted in a long arc:

The fact that it was on the edge of “caustic” space, which is a ripple in the fabric of space, was very helpful in finding the object. enhanced her glow and helped her stand out.

In addition to the distance from Earthsize Earendel It is also what attracts attention. Scientists hope that she has at least 50 times the mass of the sun and whatever a million times brighter. Because it didn’t have much access to heavier elements during its formation, this may be the first evidence of ancient “Population III” stars that are made up of only hydrogen and helium.

As indicated Enggetbut Earendel has yet to be confirmed as a star.but it could happen soon. The researchers now intend to use the telescope James Webb use high infrared sensitivity to check the star and study it in more detail.
