The six planets will be visible in the days immediately leading up to Jan. 21, and for about four weeks afterward. Mars, Venus, Jupiter and Saturn should be visible to the naked eye. You'll need a high-powered viewing device like a telescope to spot Neptune and Uranus.

“Saturday evening, January 18: Venus and Saturn will appear nearest to each other. As evening twilight ends at 6:15 p.m. EST, Venus will be 30 degrees above the southwestern horizon with Saturn 2.2 degrees to the lower left. Saturn will set first on the western horizon almost 3 hours later at 9:04 p.m.”

Research and development is underway to create robots that can hunt for signs of life in the vast oceans that exist under the thick ice shells of bodies like Europa.

New research from a team of citizen scientists challenges the old idea that Jupiter's visible clouds are formed of ammonia ice.

Using commercially available telescopes and spectral filters, an amateur astronomer named Steve Hill collected data to map the abundance of ammonia in Jupiter 's atmosphere, but Hill ultimately found something that contradicted previous models of the gas giant's atmospheric composition to begin with.
