James Webb's Space Telescope (_Space Telescope_) observed the amazing hydrogen radiation emitted by a galaxy existing at an early phase in the improvement of the universe. This discovery contributes to a better knowing of the origins of space and represents another step in the survey of the universe.
The European Space Agency (_ESA_) underlines that 1 of the key technological goals of the James Webb Space Telescope is to survey the origins of the universe more accurately than always possible. We're talking about erstwhile the first galaxies were forming. See besides how James Webb's Space Telescope explores the universe.
The advanced sensitivity of the telescope to infrared light is crucial in this respect. This opens up fresh possibilities to survey how galaxies were formed and how they affected the universe. The telescope just observed an highly distant JADES-GS-z13-1 galaxy, observed just 330 million years after the large Bang. For the record, the universe is 13.8 billion years old.
Scientists are very surprised. It's a bright light emanation with a peculiar wavelength of light, known as Lyman-α emissions, for which the hydrogen atoms are responsible. The emissions proved to be much stronger than thought at specified an early phase in the improvement of the universe.
The early universe was covered with dense fog of neutral hydrogen," says Roberto Maiolino of the University of Cambridge and University College London. – Most of this fog disappeared in a process called regionalization, which ended about a billion years after the large Bang. GS-z13-1 was observed erstwhile the universe was only 330 million years old, yet it inactive shows amazingly clear, distinctive Lyman-α emanation signal.
In the meantime, it can only be seen erstwhile the fog completely falls. This consequence was entirely unexpected, looking at the explanation of early formation of galaxies, and truly amazed astronomers. The discovery of Lyman-α radiation from this galaxy is crucial for knowing the early universe – scientists emphasize.
The origin of the radiation is not yet known. Researchers speculate that ionized hydrogen produced by a population of unusual, very massive, hot and bright stars may be the surrounding galaxy. They may even have been typical of this period. Another solution can be the active center of the galaxy, powered by supermassive black holes.
It was clear that Webb, following the footsteps of the Hubble Space Telescope, would be able to discover more and more distant galaxies. However, as the case of the GS-z13-1 shows, it was always expected to be a surprise what he would uncover about the nature of the emerging stars and black holes arising at the edge of cosmic time – points out Peter Jakobsen from the University of Copenhagen.
According to the European Space Agency, the James Webb Space Telescope has a advanced sensitivity to infrared light. This means that the telescope can observe galaxies and stars in the mediate of dense fog, which is possible thanks to advanced technology. The scope of infrared light waves ranges from 0.6 micrometer to 200 micrometers. This allows the James Webb Space Telescope to observe very distant stars and galaxies.
According to NASA, the James Webb Space Telescope is able to observe very distant galaxies that existed billions of years ago. The telescope can discover fresh galaxies that are unknown to date that will appear in the future.
In 2015, the European Space Agency announced that the James Webb Space Telescope would be launched in around 2021. NASA has confirmed that the telescope will have advanced sensitivity to infrared light. James Webb's Space Telescope has advanced technologies that let you to watch very distant and highly hot stars.
This is just 1 of the many discoveries that were made utilizing the James Webb Space Telescope.
