Authorities apprehended a tourist in Florence, Italy recently after she climbed atop a Neptune fountain, leaving damage in the process.

The probe launched almost 50 years ago and is the farthest human-made object from Earth. Shutting down one of its scientific devices will help it conserve energy and continue traveling toward the edge of the solar system

Neptune, the last known major planet in the solar system gets its close-up from JWST, and the infrared view is spectacular.

Deep inside planets like Uranus and Neptune, scientists may have uncovered a bizarre new state of matter where atoms behave in unexpected ways.…
