Hubble finds the cosmic powder moons, not radiation scars

The latest observations of the Hubble space telescope reveal a turnaround in the history of Uranus moons. Instead of the expected radiation “solar burns,” the Ariel, Umbriel, Titania, and Obern moons seem to be literally collecting cosmic dust. It turns out that the strange inclination of the planet is not burning the back as foreseen, but covering the front ends of the two external moons in a kind of space grain. This result makes astronomers scratch their heads, because it is exactly the opposite of what they expected in the magnetic field of Uranus.

Dust, not radiation

According to NASA’s data Voyager 2 Vily in 1986 and decades of modeling, scientists assumed that Uranus’s lateral rotation meant magnetic field Blasted the rear side of each moon (the “rear window”) with loaded particles, darkening -a. The rear halves should look opaque and dark. Instead, Hubble’s ultraviolet data tell a different story: Titania and Oberon (the distant pair) are really darker in their main faces – the opposite than the hypothesis of radiation predicted. In other words, the effect is not damage to radiation. Instead, it seems that Uranus’s magnetosphere largely loses these moons.

A COSMIC STAR EFFECT

Spatial dust kicked Uranus distant irregular moons. Micrometeorites constantly affect these distant satellites, throwing tiny courage in within millions of years. Titania and Obernon cross this cloud of dust, collecting debris on the sides of the front, as well as insects in the stop -bear a car. This “cosmic insect splash reveals its main faces with a slightly darker and reddish shade.

Meanwhile, Ariel and Ariel walk in the shadows of dust of their bigger brothers and look on the same brightness on both sides. The big moons of Uranus went through a slow camera cosmic Car washing, spreading fronts instead of taking an UV burn. In other words, a dusty bump – not radiation – is painting these moons. It is a reminder that space can surprise us, sometimes with nothing more exotic than old and simple dust.
