A stunning "parade of planets" will grace the night sky this week, with all seven of Earth's celestial neighbors joining the show. Here's how to spot it and why it happens.

The view was acquired on Sept. 14, 2017 at 19:59 UTC (spacecraft event time). The view was taken in visible light using the Cassini spacecraft wide-angle camera at a distance of 394,000 miles (634,000 kilometers) from Saturn. Image scale is about 11 miles (17 kilometers).

The document builds on the academies' decadal survey, outlining recommended missions for NASA's next New Frontiers program.

The NASA boffins in white coats and thick-rimmed glasses have detected new signals that show the Oort cloud - the spooky shell of icy objects at the very edge of our solar system - might have spiralling arms that resemble a galaxy.

Mercury has a rocky surface when, facing the sun, can reach highs of 800 degrees while overnight lows could reach minus 290 degrees, according to the space agency. Venus holds the crown of the hottest planet in the solar system, at 900 degrees.

NASA’s Cassini spacecraft, which orbited Saturn from 2004 to 2017, took many dramatic images of the rings’ shadows on Saturn.

"From developing small robots that could swim through the oceans of other worlds to growing space habitats from fungi, this program continues to change the possible."

Nasa recently remembered a famous image of Earth as a mere pale blue dot in the distance. The famous photograph was taken in 1990 by NASA’s Voyager 1 spacecraft. The image inspired the title of scientist Carl Sagan's book,
