Illustration of Cassini diving between Saturn and its innermost rings as part of the mission's Grand Finale. The spacecraft will perform a series of 22 daring orbits passing through the yet unexplored region between the planet and its rings and collecting unprecedented data.
Eventually Cassini will plunge and burn up into Saturn's atmosphere on 15 September 2017, satisfying planetary protection requirements to avoid possible contamination of any moons of Saturn that could have conditions suitable for life.

    Cassini, NASA’s 13-year Saturn mission, has ended

    Springtime on Saturn: Cassini's wide angle camera shot 75 images showing Saturn, its rings, and some of its moons just after Spring equinox. An equinox occurs when the sun's disk is exactly over a planet's equator. It takes 30 years for Saturn to orbit the sun, so an equinox occurs every 15 Earth years, NASA says. These images were taken on August 12, 2009, about 1.25 days after the exact equinox.

Caltech researchers have found evidence of a giant planet tracing a bizarre, highly elongated orbit in the outer solar system. The object, which the researchers have nicknamed Planet Nine, has a mass about 10 times that of Earth and orbits about 20 times farther from the sun on average than does Neptune (which orbits the sun at an average distance of 2.8 billion miles). In fact, it would take this new planet between 10,000 and 20,000 years to make just one full orbit around the sun. - See more at: http://www.caltech.edu/news/caltech-researchers-find-evidence-real-ninth-planet-49523#sthash.JaLsCJd5.dpuf

Like early explorers mapping the continents of our globe, astronomers are busy charting the spiral structure of our galaxy, the Milky Way. Using infrared images from NASA's Spitzer Space Telescope, scientists have discovered that the Milky Way's elegant spiral structure is dominated by just two arms wrapping off the ends of a central bar of stars. Previously, our galaxy was thought to possess four major arms.

This artist's concept illustrates the new view of the Milky Way, along with other findings presented at the 212th American Astronomical Society meeting in St. Louis, Mo. The galaxy's two major arms (Scutum-Centaurus and Perseus) can be seen attached to the ends of a thick central bar, while the two now-demoted minor arms (Norma and Sagittarius) are less distinct and located between the major arms. The major arms consist of the highest densities of both young and old stars; the minor arms are primarily filled with gas and pockets of star-forming activity.

The artist's concept also includes a new spiral arm, called the "Far-3 kiloparsec arm," discovered via a radio-telescope survey of gas in the Milky Way. This arm is shorter than the two major arms and lies along the bar of the galaxy.

Our sun lies near a small, partial arm called the Orion Arm, or Orion Spur, located between the Sagittarius and Perseus arms.

This new image of Pluto is stunning planetary scientists. It shows the small world's atmosphere, backlit by the sun.  NASA says the image reveals layers of haze that are several times higher than predicted.

New Horizons was about 1.25 million miles (2 million kilometers) away from Pluto at the time.

Jupiter's icy moon Europa may be the best place in the solar system to look for extraterrestrial life, according to NASA. The moon is about the size of Earth's moon and there is evidence it has an ocean beneath its frozen crust that may hold twice as much water as Earth. NASA's 2016 budget includes a request for $30 million to plan a mission to investigate Europa. The image above was taken by the Galileo spacecraft on November 25, 1999. It's a 12-frame mosaic and is considered the the best image yet of the side of Europa that faces Jupiter.
