KOMPAS.com- Recently, Space Telescope Hubble successfully detect star farthest ever seen in universe.
Located 28 billion light years from Earth, the object could be a single star or a multiple star system.
Star It may also have a mass up to 500 times greater than the Sun. That means it is millions of times brighter than the Sun and was born when the universe was young.
quote Live ScienceThursday (31/3/2022) Hubble was able to see the star because of the coincidence of the star alignment behind a group of galaxies.
The gravity of the large foreground galaxies bends space and creates an effect known as gravitational lensing that magnifies starlight tens of thousands of times.
This eventually made the star visible to the Hubble instrument.
The star’s official name is WHL0137-LS, but researchers have dubbed it ‘Earendel’ which comes from Old English meaning ‘rising light’ or ‘morning star’.

Follow-up imaging from the Hubble telescope confirmed that the sightings of farthest star it’s not temporary. The star has stayed in the same place for 3.5 years.
Earendel Star itself according to researchers comes from about 900 million years after the Big Bang, which can place it as the first generation of stars in the universe.
That’s why the findings Hubble telescope detects farthest star it can also help researchers to investigate the early years the universe formed.
“When we peer into the cosmos, we also look into the past, so these extreme high-resolution observations allow us to understand the building blocks of the first few galaxies,” said Victoria Strait, one of the study’s authors.
When the Hubble Telescope detected the most distant star, Strait explained that when the light seen from Earendel was emitted, the universe was less than a billion years old. Only six percent of his current age.

“At that time it was 4 billion light-years from the proto-Milky Way. But for nearly 13 billion years it took light to reach us, the universe has expanded so that the distance is 28 billion light-years,” explained Strait.
The Hubble Space Telescope itself was launched on April 24, 1990 after decades of planning and research.
According to the Royal Museum of Greenwich in London, the telescope offers information about previously unseen objects that can help researchers study the cosmos.
Space telescope it also helps scientists create 3D dark matter maps, and helps determine the age of the universe and its rate of expansion.

And after more than three decades in orbit, the Hubble telescope has a partner to help with cosmic surveillance: the James Webb Space Telescope, which launches December 25, 2021.
The Webb telescope will use its enormous main mirror to capture infrared views of some of the oldest and faintest objects in space, such as the earliest stars and galaxies.
And because there is still much to know from Earendel star With these new discoveries, such as mass, temperature, and spectral classification, the researchers hoped to obtain more precise data from observations made by Webb.
This includes helping astronomers find stars that are farther away than Hubble can detect.
The findings of the farthest star captured by the Hubble telescope have also been published Wednesday, (3/30/2022) in the journal Nature.
