Washington — NASA has released images of distant galaxies 13 billion years ago. This is the first glimpse from the most powerful telescope ever launched into space, promising to rebuild our understanding of the dawn of space.
The first batch of full-color, high-resolution images that took weeks to render from raw telescope data was intended to provide compelling initial images from Webb’s main research areas and previews of future scientific missions. Selected by NASA.
Built for NASA by aerospace giant Northrop Graman, the $ 9 billion infrared telescope will revolutionize astronomy by allowing scientists to peek into space farther and more clearly than before. Is expected.
Webb, a partnership between NASA, the European Space Agency and the Canadian Space Agency, was launched on Christmas Day 2021 and arrived at a destination in the solar orbit about a million miles from Earth a month later.
Once there, the telescope went through a one-month process to unfold all the components, including the tennis court-sized awning, adjust the mirrors, and calibrate the equipment.
Astronomers have been fine-tuned and fully focused on the Webb, making it a competitive choice for exploring galaxy evolution, star lifecycles, distant exoplanet atmospheres, and exoplanet satellites. Evolve a list of scientific projects.
Until Friday, when the space agency posted a list of five objects selected for its large public release at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, the assortment of introductory photos will be kept tight. Was there.
US President Joe Biden jumped at the announcement at his own White House briefing on Monday and released the first photo-a cluster of galaxies called SMACS0723 revealing the most detailed glimpse of the early universe ever recorded. Image of.
Among the other four Webb “targets” that get close-ups on Tuesday are two giant gas and dust clouds blown into space by a star explosion, forming a new star incubator. Earth.
The debut collection includes another cluster of galaxies known as Stephan’s Quintet. It covers several galaxies that were first discovered in 1877 and described by NASA as “trapped in a space dance of repeated close encounters.”
NASA also announces the first spectroscopic analysis of Webb for exoplanets. This is about half the mass of Jupiter, which is more than 1,100 light-years away. It reveals the molecular properties of filtered light that passes through the atmosphere.
Webb is designed primarily to see the subject in the infrared spectrum, and is about 100 times more sensitive than its 30-year-old predecessor, the Hubble Space Telescope, which operates primarily at optical and UV wavelengths.
The much larger condensing surface of Webb’s primary mirror (an array of 18 hexagonal segments of gold-coated beryllium metal) allows objects to be observed at a much greater distance than Hubble and other telescopes.
All five Webb implementation goals were previously known to scientists, but NASA officials have promised that Webb images literally capture the subject in a whole new light.
SMA CS0723 image Biden, published on Monday, shows a cluster of galaxies 4.6 billion years ago. Its combined mass acts as a “gravitational lens”, distorting space and significantly magnifying light from the farther galaxies behind it.
According to NASA Secretary Bill Nelson, at least one of the faint old light spots (composites of images of light of different wavelengths) that appear in the “background” of a photograph dates back more than 13 billion years.
Therefore, it is only 800 million years younger than the big bang, the theoretical flash point that started the known expansion of the universe about 13.8 billion years ago.
According to NASA, gem-studded composite photographs provide “the most detailed view of the early universe” and “the deepest and clearest infrared image of the distant universe” ever taken.
Thousands of galaxies in the image were captured by small empty patches about the size of a grain of sand held by someone standing on Earth at arm length, Nelson said. -agency
