Giant planets around young star raise questions about how planets form
Researchers have identified a young star with four Jupiter and Saturn-sized planets in orbit around it, the first time that so many massive planets have been detected in such a young system. The system has also set a new ...
Five in a row—the planets align in the night sky
For the second time this year, the five brightest planets can be seen at the same time. You can catch them by looking towards the western sky after sunset. The planets will form a line rising up from the horizon.
First results from Cassini's final mission phase show protons of extreme energies between the planet and its dense rings
Approximately one year ago, a spectacular dive into Saturn ended NASA's Cassini mission—and with it a unique, 13-year research expedition to the Saturnian system. In the mission's last five months, the probe entered uncharted ...
Groundbreaking science emerges from ultra-close orbits of Saturn
New research emerging from the final orbits of NASA's Cassini spacecraft represents a huge leap forward in our understanding of the Saturn system—especially the mysterious, never-before-explored region between the planet ...
In its final days, Cassini bathed in 'ring rain'
On its last orbits in 2017, the long-running Cassini spacecraft dove between Saturn's rings and its upper atmosphere and bathed in a downpour of dust that astronomers call "ring rain."
Latest insights into Saturn's weird magnetic field only make things weirder
Some of the last data from the Cassini mission reveals more structure in Saturn's magnetic field, but still no answer as to how it formed.
Surprising chemical complexity of Saturn's rings changing planet's upper atmosphere
Political humorist Mark Russel once joked, "The scientific theory I like best is that the rings of Saturn are composed entirely of lost airline luggage."
Saturn's famous hexagon may tower above the clouds
The long-lived international Cassini mission has revealed a surprising feature emerging at Saturn's northern pole as it nears summertime: a warming, high-altitude vortex with a hexagonal shape, akin to the famous hexagon ...
New family photos of Mars and Saturn from Hubble
In summer 2018 the planets Mars and Saturn are, one after the other, in opposition to Earth. During this event the planets are relatively close to Earth, allowing astronomers to observe them in greater detail. Hubble took ...
