The Webb Telescope finds a dense cosmic knot in the early universe

It seems that eThe Webb Space Telescope continues its streak He hits. The famous telescope has Discover the knot It consists of a very red quasar surrounded by it A group of massive galaxies that have been around for about 11 years500 million years.

he is The photo comes only a day after the gorgeous shot of Iconic Pillars of CreationThe same Cloud From the gas you captured The Hubble Space Telescope in 1995.

Quasars are the active centers of visible galaxies very bright The night sky quasars have supermassive black holes in their cores, and are located above them Vortex of superheated plasma. from time to time this Launching quasars Huge blasts of energy that travels the universe.

The quasar I photographed newly the web It is called SDSS J165202.64 + 172852.3. It existed in the ancient universe, and the light we see from it traveled for it Billions of years before it arrives mirrors web.

Well, the Pillars of Creation seemed much clearer than this quasar In the eyes of the web. But this is the last element this is much further It is older than Earth by billions of years. Quasar light is deflected red, which means that its wavelengths have literally been stretched by the expansion of the universe, diverting the light toward the red side of the electromagnetic spectrum.

Ago Web sees the universe in the spectrum Infrared, the telescope was perfect Thanks for checking this quasar Near Infrared Spectrometer (or NIRSpec).

Previous analysis of the quasar seems to indicate that that its host galaxy may merge with another unseen galaxy. but a picture Webb reveals a more complex truth and exciting: The quasar galaxy revolves around At least three other galaxies. The NIRSpec image shows the quasar visible through Various color filters for the tool.

“Our first look at the data quickly revealed clear signals of important interactions between neighboring galaxies,” he said. Andre Weiner, an astrophysicist at Johns Hopkins University and a member of the telescope team Webb, in a statement issued by the European Space Agency. “The sensitivity of the NIRSpec instrument was immediately apparent and it was clear to me that we were in a new era of infrared spectroscopy.”

Galaxies are close enough together and intricately intertwined that they are known as a galactic “knot”: it is nearly impossible to separate the light of a quasar from the light of surrounding galaxies using ground-based telescopes.

The vision is unparalleled From Webb helps solve some of those age-old dilemmas.which in turn has implications for scientists’ understanding of the formation of galaxies in the early universe and even the nature of dark matter halos.
