The Solar System’s smallest planet has contracted by nearly 19 km (12 miles) across, as crater debris masked telltale wrinkles on its surface, according to new research led by the German Aerospace Center’s Institute of Space Research.

New data from NASA’s Juno spacecraft show temperatures spike more than 20 degrees Celsius just a few meters under Io’s surface, providing the first look at what’s happening below the crust of the Solar System’s most volcanic world.

Astronomers Uncover Hidden Structures Surrounding Orion Nebula

Extended Orion nebula shell sampled by HI emission from the combined VLA and FAST observations (shown in red), Hα emission from the European Southern Observatory Digitized Sky Survey (shown in green), and 3.4-μm emission registered by the Wide-field Infrared Survey Explorer (WISE) satellite (shown in blue).

Using the Karl G. Jansky Very Large Array (VLA) s and the Five-hundred-meter Aperture Spherical Radio Telescope (FAST), astronomers have created the sharpest-ever radio maps of neutral hydrogen around the Orion Nebula.
