For the first time in the history of astronomy, Telescope James Webb recorded Neptune a bright polar glitter. This has become an important milestone in the work of ice giants. Published in İş Magazine Nature astronomy.
Previously, scientists only suggested the existence of sparkle on Neptune: in 1989, when Voyager 2 was a range, tips were observed, but the approval remained unreachable. Now, thanks to the infrared sensitivity of the telescope, it was not only possible to see these phenomena, but also with unprecedented details.
Researchers have revealed an important marker of the polar glow of a Trivo -Doğan Cation (H3+) – previously discovered in Jupiter, Saturn and Uranus. However, the location of the glow on Neptune is unusual: instead of poles, for example in the middle latitudes that correspond to South America’s earth. The reason for this is that the Neptune magnetic field is inclined to the 47 degree rotation axis and the interaction of the solar wind with the atmosphere creates a completely different picture.
Telescope also noted that Neptune’s upper layers unexpected cooling. It turned out that the temperature in 2023 was twice as low as Voyager 2. This explains why the glittering remained hidden for so long – their densities were significantly lower than expected.
New observations will help astronomers better understand the dynamics of the Neptune magnetic field and the interaction of the solar wind. In the future, scientists plan to explore the planet during the full solar cycle, which will shed light on the origin of Neptune’s unusual magnetic field and evolution.
