A Cosmic Survey Reveals the Universe's Hidden Side

Universe Today - Mon, 04/27/2026 - 10:30am

A team of scientists at the University of Virginia is using a telescope in Arizona to study cosmic structure and the result is the largest 3D map of the Universe ever created. The Dark Energy Spectroscopic Instrument (DESI) at Kitt Peak National Observatory is their tool, and the ultimate goal is to get a handle on the mystery of dark energy by charting the positions of galaxies.

Scientists Find Peculiar Differences in Two Uranian Rings

Universe Today - Sun, 04/26/2026 - 9:39pm

The planet Uranus is a weird place. Not only does it roll around the Sun on its side once every 84.3 Earth years, it also sports a spindly set of rings corralled in some places by strange little moons. Two of those rings, the μ (mu) and ν (nu) rings are incredibly faint, which makes them challenging to study.
