The Hubble Telescope has possibly photographed the oldest object ever seen by anyone on Earth. The telescope’s well-known photograph known as “Deep Field” seemed to only show empty, blank patches of space, but it actually revealed that there were objects inside those supposedly unoccupied blotches. In reality the blank areas were completely full of objects far away. The original picture, taken back in 1996, shows thousands of galaxy clusters in what was thought to have been just a blank part of the sky.
Hubble has apparently repeated the feat by taking a new set of photographs, which are being called the “Frontier Fields”. These pictures are showing images that look even farther back in time of the universe than any prior pictures. This same feat again accomplished by Hubble includes showing a galaxy that is believed to be about 13 billion light-years away from Earth. This would make it the lead candidate for the most distant item that has ever been seen.
The pictures show quite the treasure chest of formerly undetected galaxies and that includes the above mentioned object which just might be among the most distant things to ever be seen by anyone on Earth. The contender galaxy, which has been labeled Abell2744 Y1, seemed to lie about 13 billion light-years away, as was mentioned above. This means that the light from the object has taken at least that long to reach the Earth. This object is believed to have been created when the universe was around the age of 650 million years old. That amount of time is practically nothing when speaking in terms of space measurements.
These ancient galaxies could be very different compared to the ones that seem to come into being now. For example, Abell2744 Y1 is around 30 times tinier in size than the Milky Way, yet it is making at least eight or nine times as many stars as the galaxy that the Earth is does. That was meant to say the object did, when the cosmos was brand new.
Such photographic images also unveil numerous groups of former unnoticed galaxy clusters, which happen to include Abell2744 Y1 inside one of them. At such an early time, the various galaxies were bright, shiny objects that were small and near to one another. They were also so close that they showed up almost everywhere, stated Garth Lillingworth, who is an astronomer and works at the University of California. He was the scientist who offered a look at various astoundingly bright galaxies that were produced in this prime time period. He stated that not only Hubble had picked them up but also NASA’s Spitzer Telescope.
It is essential that astronomers and scientists understand how these original galaxies were created to comprehend how Earth’s own galaxy today was first formed, explained Eilat Glikman, who is an astronomer at a college in Vermont.
Therefore the Hubble Telescope’s well-known photograph, “Deep Field,” seemed to only show empty, blank patches of space. But it actually revealed that there were objects inside those supposedly unoccupied blotches. In reality, the blank areas were completely full of objects far away.
