NASA and the European Space Agency (ESA) this week unveiled images of 19 spiral galaxies, some located more than 60 million light years away. A new technical feat achieved thanks to the James Webb telescope.
Swirling in space. NASA and the European Space Agency, ESA, this week unveiled very detailed images taken by the James Webb telescope. Taken up by CNN this Thursday, February 1, they show 19 spiral galaxies and the tens of millions of stars that these systems house.
“These observations can help astronomers better understand star formation and the evolution of spiral galaxies like ours,” the Milky Way, explains the American media.

On his websiteNASA explains that Miri (Mid-Infrade Instrument) data highlights stars that have not yet formed, still locked in gas and dust.
“The most recent stars” are found at the ends of the dusty peaks, underlines Erik Rosolowsky, professor of physics at the University of Alberta in Edmonton (Canada).

These galaxies are located several tens of millions of light years from the Milky Way and were observed in infrared light as part of the “Phangs” program in which more than 150 astronomers are involved.

According to NASA, the James Webb Telescope has enough fuel to operate for 20 years. Researchers around the world can reserve observing time with the telescope, whose schedule is carefully developed in one-year increments.
Since it was operational, dozens of impressive images have been captured: rains of sand on the “cotton candy” planet, the birth of around fifty stars and numerous nebulae and other galaxies. .
