1. Secrets of the GN-z11 galaxy
Using observations from this year’s James Webb Space Telescope, an international team of researchers has deepened the study of GN-z11, a galaxy 13.4 billion light-years away that formed just 430 million years after the Big Bang.
This galaxy was first detected by Hubble, but recent Webb observations have revealed extraordinary details, including evidence for the existence of an active supermassive black hole at its center. This object, which has an estimated mass of about 2 million times the mass of the Sun, will be intensely active and produce high-speed galactic winds..
In addition to the black hole, scientists also identified a region in the galaxy’s halo containing ionized helium gas; This indicates the existence of still intact primordial matter, possibly from the formation of the universe. This is the first to shine in the Cosmos, Phase III, composed almost entirely of hydrogen and helium. It increases the chances of population stars being detected.
These discoveries expand our knowledge of how the first galaxies evolved and how complex structures emerged in the early universe.
2. Saturn’s hexagonal storm!
The hexagonal storm at Saturn’s north pole is a unique atmospheric phenomenon in the Solar System and has attracted the attention of scientists since its discovery by the Voyager probe in the 1980s. A nearly perfect hexagonal structure more than twice the size of Earth, approximately 30,000 kilometers in diameter.
This formation consists of storm clouds rotating at high speed around the planet’s pole, creating a stable, long-lived shape that persists for decades, maintained by intense jet streams moving at approximately 200 mph.
This phenomenon occurs due to complex interactions between atmospheric winds and the rotation of the planet, as well as changes in the density and temperature of gas layers.
Laboratory simulations suggests that the hexagon may be the result of liquids moving circularly in a jet streamforming polygonal patterns under certain conditions.
The color differences observed in the storm, including shades of blue and gold, are due to seasonal changes and the chemical composition of Saturn’s atmosphere, primarily methane and ammonia.
3. The heart of the Milky Way!
As if it were no longer news, James Webb confounded the understanding of our own galaxy this year. Their latest observations captured the Sagittarius C region, located about 300 light-years away from the Milky Way’s central black hole, Sagittarius A*.
The telescope uses NIRCam, an observation tool in the infrared bands. Revealed nearly 500,000 previously unseen structures of stars and ionized gas. This hydrogen-rich region presents thin, disoriented filaments that have intrigued scientists.
Besides being an impressive technical achievement, studying the Sagittarius C region provides clues about how galaxies evolve over time, especially near supermassive black holes. playing a crucial role in galactic dynamics.
Additionally, data analysis opened a new window into the study of star formation in dense and violent environments such as the galactic center.
