James Webb Telescope: His Summer Album

Harvesting from the sky continues in abundance at the James Webb Space Telescope (JWST). As a result of cooperation between US, European and Canadian space agencies, the Hubble telescope has been in an orbit of 1.5 million km from Earth since the end of January. After the July 11-12 fireworks that showed its first unusually detailed images of the Carina, the collision of galaxies (Stephan’s Quintet), a part of the sky studded with galaxies, a planetary nebula (known as the “Australian Ring”) and a survey of the formation of The atmosphere of an exoplanet, the summer harvest is just as good.

“It is extraordinary. Expected performance exceeded. Data quality delivers on promises. We are living a dream!”excited Hervé Doll, a professor at the Institute of Astrophysics at the University of Paris-Saclay. “ The machine is amazing. It can image Jupiter as well as distant galaxies that are one to ten million times fainter.believes Olivier Bernet, researcher at the National Center for Scientific Research at the Institute for Research in Astrophysics and Planetary Sciences in Toulouse.

Every day, the JWST 6.5-meter mirror points to sources as diverse as galaxies or very distant stars that appeared in the first billion years of the universe, closer clusters of galaxies, supernovae, exoplanets, the planets of our solar system, or comets. Or asteroids… We have moved to this data.Hervey Doll announces who Already submitted an article About the hypothetical existence of the most distant galaxy cluster ever observed, 600 million years after the Big Bang. A proto-cluster is a geographical grouping of galaxies, here are less than ten, that will become a real cluster after millions of years, with a lot of hot gas inside. I haven’t written an article at all in two weeks. We set out in the hotel lobby with a colleague looking at the deep sky photo, a few days after it aired on July 11th. We expected results quickly, but this is almost instant! »Says an astrophysicist.

But it was one of his colleagues at the ENS de Lyon, Johann Richard, with American, English and even Swiss researchers, who painted the fastest. As of July 14, 7:55 p.m. Paris time, less than 3 days after the first image was revealed, Puts an initial copy online on the specialized arXiv.org موقع To distinguish a galaxy that distorts the image of the sky and acts as a magnifying glass against the distant galaxies behind it. “We even started with the naked eye analysis from the provided image. Then we used more raw data., recalls Johann Richard, who has since co-signed three more advance copies. Thirteen seconds later, Another team respondsOn the same topic…
