"Downtown" space is just about 25,800 light-years away, a short hop in cosmic distances. A light year is the number of years that light travels, in this case to reach the Earth.
The recent discovery of abundant helium in Saturn's structure may answer questions about the origins of gaseous planets in and out of our solar system.
NASA has peered into the chromosphere to return multi-height measurements of its magnetic field. The sun's magnetic fields give rise to different eruptions in its outer atmosphere.
Thirty years ago, Voyager 2 made a flyby on Uranus which sent valuable data back to Earth. But it was not only recently that scientists discovered that there are plasmoids in Uranus, an indication that its atmosphere is being stripped away.
NASA is tracking a dent in Earth's magnetic field, an unusually weak spot in the field called the South Atlantic Anomaly, which allows harmful particles from the sun from going deeper into the Earth's surface than normal, which could be bad news for the low orbit satellites that pass through it.
Jupiter has fascinated sky-gazers for millennia but it wasn’t until probes are sent to the planet that scientists began to unravel its deepest secrets. Now, new scientific data from Juno, the most recent spacecraft to rendezvous with the gas giant, shows that Jupiter has many more secrets still.
