James-Webb Telescope: His Summer Album

Harvests from the sky continue to be a boon for the James-Webb Space Telescope (JWST). The successor to the Hubble Space Telescope has been 1.5 million kilometers from Earth since late January, the result of a collaboration between the US, European and Canadian space agencies. After the July 11 and 12 fireworks, the study of the atmospheric composition of a nebula (Carina), colliding galaxies (Stephen’s Quintet), part of the sky galaxies, a planetary nebula (called the “astral ring”) and an exoplanet, summer harvests will be good.

“It’s extraordinary. Expected performance is high. Data quality lives up to promises. Living the dream! »enthuses Hervé Dole, a professor at the Institute of Space Astrophysics at the University of Paris-Saclay. The tool is amazing. It is one to ten million times fainter than Jupiter and distant galaxies.CNRS researcher Olivier Bernay at the Astrophysics and Planetology Research Institute in Toulouse believes so.

Each day, JWST’s 6.5-meter mirror points to a variety of sources, such as the most distant galaxies or stars, galaxies, supernovae, exoplanets, planets of our solar system, comets or asteroids that formed in the first billion years of the universe. “We jumped on this data.”Herve Dole announces who Already submitted an article On the hypothetical existence of the most distant proto-cluster of galaxies yet to be discovered, 600 million years after the Big Bang. A proto-cluster is a geographical group of galaxies, here less than ten, that after millions of years becomes a true cluster, containing a lot of hot gas. “I have not written an article for two weeks. A few days after the broadcast on July 11, we found ourselves in a hotel lobby with a colleague looking at a picture of Deep Sky. We expected to get results quickly, but this was almost immediate! »Says an astrophysicist.

But one of his colleagues at ENS de Leon, Johann Richard, along with other American, English and Swiss researchers, drew much faster. Starting July 14, at 7:55 PM Paris time, less than 3 days after the first film was released, it Online preprints at the dedicated site arXiv.org Distorting the image of the sky, it characterizes the Milky Way, acting as a magnifying glass with distant galaxies beyond. “We started the analysis with the naked eye from the supplied image. Then we used more raw data., recalls Johann Richard, who co-signed three other reservations. Thirteen seconds later, Another group respondsOn the same topic…
