James Webb discovers a new moon of Uranus.

The James Webb does not stop, it is a wonder, a team of researchers from the United States has discovered a new moon of Uranus, which expands the family of natural satellites of this strange planet A29. The detection was made after analyzing an observation taken by the James Webb on February 2, 2025.


The Moon was detected in a series of 10 long exposure images of 40 minutes and it was a moon that could not even be captured by the Voyager probe that flew over, and which is the only spacecraft that has passed near Uranus almost 40 years ago. It is estimated that this Moon is about 10 km in diameter and orbits Uranus 56,000 km from the center of Uranus, so it would be about 25,000 km away. of the planet's clouds.


Astronomers claim that no other planet has as many small inner moons as Uranus, nor does it have its complex interactions with the rings. What astronomers point out is that all this could be a clue to a chaotic history, perhaps the destruction of an ancient larger moon.




Apart from that, Uranus has a very strange rotation, it is literally lying down, it has an inclination of 98º and this causes very curious effects, technically Uranus rotates on itself every 17 hours and 14 minutes, that is how long a day would last on Uranus so it would be normal for a planet, but in Uranus as it is lying down, one of the poles is normally facing the sun, which means that if you were in the hemisphere that is illuminated by sunlight, you would not see the sun set on 21 years, it would be a sunny day for 21 years, while in the opposite hemisphere they would be in a frozen night during the same period, 21 years, and that would occur during the periods close to the solstice, while during the equinoxes the planet would already experience a more normal day-night cycle, reaching a point where the day would last those 17 hours and 14 minutes.


The year on Uranus lasts 84 Earth years and the seasons also last a long time. It is believed that Uranus is lying down like this because it received the impact of a planet that would have twice the mass of the Earth and this caused the planet to lie down. It could be that this crash also caused all these little moons around it and the rings and so on, the problem is that there has only been one ship that has visited it.


Beneath its clouds, about 5,000 km deep (Uranus is approximately 244,000 km in radius) once you descend into the clouds, you would find a frozen ocean of water and ammonia, an ocean of water and ammonia, and also with organic compounds, methane and other carbon compounds, but although it sounds nice, it is not at all because the pressure in that ocean is about 2500 times the atmospheric pressure. on the surface of the Earth and it is also quite cold, in addition, in 2018 I remember that they released a report where they showed that there was a gas that is the typical gas that produces the smell of rotten eggs, dangerous hydrogen sulfide.
