Thermal images taken of Uranus, showing the planet's rings clearly

Although Saturn sports the most impressive ring system in our neighborhood, it’s not alone. Uranus is also packing some rings, although they’re usually too faint to see without a powerful telescope. But a striking new set of images shows these rings in very clear detail thanks to thermal imaging, while also allowing astronomers to measure their temperature for the first time.

Our solar system has several “belts” of rocky planetesimals that are essentially the crumbs left over from the formation of the planets and moons. But new research suggests some of them could actually be alien, captured during close flybys wi… Continue reading Close encounter with alien star could explain ’Oumuamua, debunk Planet Nine→
