The James Webb Space Telescope (JWST) is transforming our understanding of trans-Neptunian objects (TNOs), the icy remnants of planetary formation. As part of the DiSCo-TNOs project, researchers have used JWST’s near-infrared data to identify two distinct groups among spectrally red TNOs, believed to be rich in organics. The key difference between these groups is the presence of surface ices—particularly methanol (CH₃OH) ice.

Since its launch in 2020, Solar Orbiter has carried out a number of gravity assists at Earth and Venus to gradually shrink its orbit and bring it closer to the Sun, but never before has it come as close to a planet as it did on 18 February 2025, when it came within just 379 km of Venus. For comparison, astronauts aboard the International Space Station orbit the Earth at an average altitude of 408 km.
