NASA experts have shown never-before-seen images of the galaxy MACS0647-JD that were actually captured by the space agency’s Hubble Telescope 10 years ago. However, with the expansion of technology and the accuracy of the image achieved by James WebbNew photos released.
According to a statement released by NASA on Wednesday (26/10), researchers have gone into more detail in the images and compared the old Hubble images to the new images from James Webb.
Check out the pickup difference between Hubble and James Webb:
Dan Koe, of the European Space Agency’s AURA/STScI and Johns Hopkins University, says the first Hubble images of MACS0647-JD were his first work as a galactic researcher. “With Hubble, it was just a pale red dot – we could say it was very young, just a small galaxy in the first 400 million years of the universe – and now we’ve searched with Webb and we’ve been able to solve two wills!”
He further explains that researchers are studying whether two galaxies or two star groups are within a galaxy. “We don’t know, but these are the questions Webb is designed to help us answer,” he says.
According to Tiger Hsiao of Johns Hopkins University, different colors represent different characteristics. “The blue star has a very young star formation and almost no dust, but the little red body has more dust inside and is older. Its stellar mass is probably different as well,” he explains. “Maybe we will see galaxies merge in the early universe,” he says.
Scientist Rebecca Larson of the University of Texas at Austin points out that until then, it had not been possible to study galaxies in the early universe in great detail and that with James Webb such analyzes became possible. “It’s amazing how much information we get that we haven’t been able to see before. And that’s not a deep field. This isn’t a long exposure. We haven’t even tried using this telescope to look at a point for a long time. That’s just the beginning!”
