NASA: the Webb telescope reveals the first splendid images from the cosmos
There NASA said Friday that the first cosmic images since space telescope James Webb they will include unprecedented views of distant galaxies, bright nebulae, and a distant giant gas planet. US, European and Canadian space agencies are preparing for a big reveal on July 12 of the first observations of the $ 10 billion observatory, Hubble’s successor that it will reveal new insights into the origins of the universe.
An international committee decided that the first wave of color science images would include the Carina Nebulaa huge cloud of dust and gas 7,600 light-years away, as well as the Southern Ring Nebula, which surrounds a dying star 2,000 light-years away. The Carina Nebula is famous for its towering pillars which include “Mystic Mountain”, a three light-year-high cosmic pinnacle captured in an iconic image by Hubble.
Webb, a new gas giant and other distant galaxies
Webb also performed a spectroscopy, a light analysis that reveals detailed information, on a distant gas giant called WASP-96 b, discovered in 2014. Nearly 1,150 light-years from Earth, WASP-96 b has about half the mass of Jupiter and revolves around its star in just 3.4 days. Then it comes Stephan’s Quintet, a compact galaxy 290 million light years away. Four of the five galaxies within the quintet are “locked in a cosmic dance of repeated close encounters,” NASA said.
Finally, and perhaps most tempting of all, Webb collected an image using galaxy clusters in the foreground called SMACS 0723 as a kind of cosmic magnifying glass for extremely distant galaxies. This is known as “gravitational lenses” and uses the mass of the foreground galaxies to bend the light of the objects behind them, just like a pair of glasses.
