The Webb Space Telescope provides a new look at black holes

Webb has begun to map the universe, and deliver the goods it was built for: this week he provided a previously unseen glimpse into the structure of a supermassive black hole at the core of a galaxy that is part of Stefan's Five.

But last week, we told you here in detail about the James Webb Space Telescope.

Among his first series of demonstration photographs, intended to give an idea of ​​the various observational missions of the new space telescope, were photographs of "Stefan's quintet", a group of closely spaced galaxies first discovered from the Marseille Observatory by astronomer Edouard Stéphane.



As part of this observation, the Webb telescope also began training its near-infrared spectrometer, known as NIRSpec.

and pointed it towards the black hole at the heart of the uppermost galaxy in the Stefan quintet.

The spectrometer, which is a device that breaks light into different wavelengths, allows scientists to identify the chemical composition of celestial bodies according to the wavelengths they emit.

The sophisticated observation device on Webb managed to penetrate and give a new image of the enormous black hole at the heart of the galaxy, even though it is surrounded by cosmic dust.

The result, as the European Space Agency explained in a series of tweets on Twitter, is that Webb was able to observe the black hole at wavelengths that were not possible until now, and among them, the wavelength corresponding to hydrogen in various compositions, and ionized iron atoms surrounding the black hole.

Combining the photographs at different wavelengths and analyzing them, scientists have been able to map the structure and flow of gas into the black hole, as well as massive gas emissions thrown out in jets of radiation, caused by the black hole's high density.



NIRSpec, the near-infrared spectrometer was built by a series of European companies for the European Space Agency, which is one of the three partners in the Webb Space Telescope project, alongside NASA and the Canadian Space Agency. After over 20 years of development, an investment of 10 billion dollars and months of tweaks, the Web has finally begun to aid scientific endeavors—and in the meantime, it certainly seems to be delivering the goods.
