For three decades, astronomers thought that only Saturn's moon Janus confined the planet's A ring -- the largest and farthest of the visible rings. But after poring over NASA's Cassini mission data, astronomers now conclude that the teamwork of seven moons keeps this ring corralled.
NASA's Juno spacecraft has helped explain how volcanoes on the moon Io spew particles that are flung out by Jupiter's magnetic field, before rebounding back. A high-speed atmospheric encounter on the return leg creates the Red Giant's once mysterious transient auroras.
The space environment is no longer the sole preserve of government agencies. Private companies have entered the exploration domain and are propelling the sector forward more vigorously and swiftly than would be the case if left to governments alone.
