On its eighth flyby of Jupiter, our Juno spacecraft caught this striking view of the gas giant planet. Taken on Sept. 1, 2017, Juno was soaring 4,707 miles (7,576 km) from the tops of the planet's clouds in this view.

Juno is currently at Jupiter to understand the origin and evolution of the planet. Underneath its dense cloud cover, Jupiter safeguards secrets to the fundamental processes and conditions that governed our solar system during its formation. As our primary example of a giant planet, Jupiter can also provide critical knowledge for understanding the planetary systems being discovered around other stars.

With its suite of science instruments, Juno will investigate the existence of a solid planetary core, map Jupiter's intense magnetic field, measure the amount of water and ammonia in the deep atmosphere, and observe the planet's auroras. Juno will let us take a giant step forward in our understanding of how giant planets form and the role these titans played in putting together the rest of the solar system.

An unusual object in the asteroid belt is, in fact, two asteroids orbiting each other that have comet-like features. These include a bright halo of material, called a coma, and a long tail of dust. This time-lapse, assembled from a set of Hubble Space Telescope photos, reveals the asteroid pair, called 2006 VW139/288P.
The pair is orbiting each other at a distance of 60 miles and was imaged in September 2016. The more recent Hubble observations revealed ongoing activity in the binary system. We detected strong indications for the sublimation of water ice due to the increased solar heating – similar to how the tail of a comet is created.
The team estimates that 2006 VW139/288P has existed as a binary system only for about 5,000 years. The most probably formation scenario is the breakup due to fast rotation.

Hurricane Maria in infrared. Our Suomi NPP satellite captured this thermal image of Hurricane Maria early Wednesday morning. At the time, Maria’s eye was just east of the U.S. Virgin Islands, and its northwester quadrant stretched over Puerto Rico.

This image shows very cold cloud top temperatures in the powerful thunderstorms in Maria’s eyewall. Rainfall analysis from another satellite (our Global Precipitation Measurement mission) found that some extreme storms within the hurricane’s feeder bands were dropping rain at a rate of greater than 5.4 inches per hour.

The aurora borealis, Latin for northern lights, over Canada is sighted from the International Space Station (@iss) near the highest point of its orbital path. The station’s main solar arrays are seen in the left foreground.
There are currently six people living and working on the space station, which is located 250 miles above the Earth. As it orbits our home planet, they conduct important research in the unique microgravity laboratory. This science will not only help us travel farther into the solar system, but also has direct benefits to life on Earth.

Look up in the sky tonight and see Saturn!
This month Saturn is the only prominent evening planet low in the southwest sky. Look for it near the constellation Sagittarius. Above and below Saturn--from a dark sky--you can't miss the summer Milky Way spanning the sky from northeast to southwest!
Grab a pair of binoculars and scan the teapot-shaped Sagittarius, where stars and some brighter clumps appear as steam from the teapot. Those bright clumps are near the center of our galaxy, which is full of gas, dust and stars.

Far, far away…55 million light-years to be exact, lies this galaxy containing a massive star-forming cloud. This large cloud composed of ionized hydrogen is the only massive star-forming complex in the entire galaxy.

Imaged by the Hubble Space Telescope (@nasahubble), this barred spiral galaxy is famous for containing an especially extensive HII region, a large cloud composed of ionized hydrogen (or HII, pronounced “H=two,” with H being the chemical symbol for hydrogen and the “II” indicating that the atoms have lost an electron to become ionized). This cloud sits at the lower left end of the galaxy’s central “bar” of stars, a structure that cuts through the galactic core and funnels material inwards to maintain the star formation occurring there.

After two decades in space, our Cassini spacecraft has ended its journey of exploration. Having expended almost every bit of the rocket propellant it carried to Saturn, operators deliberately plunged Cassini into the planet to ensure Saturn's moons will remain pristine for future exploration—in particular, the ice-covered, ocean-bearing moon Enceladus, but also Titan, with its intriguing pre-biotic chemistry.
Swipe to explore some of Cassini’s final images that were sent to Earth in the hours before its final plunge. As the spacecraft made its fateful dive into the planet's atmosphere, it sent home additional data in real time. Key measurements came from its mass spectrometer, which sampled Saturn's atmosphere, telling us about its composition until contact was lost.
While it's always sad when a mission comes to an end, Cassini's finale plunge is a truly spectacular end for one of the most scientifically rich voyages yet undertaken in our solar system. To truly reveal the wonders of Saturn, we had to go there.

Get up close and see Jupiter in this new series of enhanced-color images from our Juno spacecraft. It recently performed its eighth flyby of the gas giant planet and captured this sequence of images taken on Sept. 1 from 6:03 p.m. to 6:11 p.m. EDT. At the times the images were taken, the spacecraft ranged from 7,545 to 14,234 miles (12,143 to 22,908 km) from the tops of the clouds of the planet.

Underneath its dense cloud cover, Jupiter safeguards secrets to the fundamental processes and conditions that governed our solar system during its formation. Juno is working to unlock Jupiter's secrets, increasing our understanding of the origin and evolution of the planet. As our primary example of a giant planet, Jupiter can also provide critical knowledge for understanding the planetary systems being discovered around other stars.

LIFTOFF! NASA astronauts Mark Vande Hei, Joe Acaba and Russian cosmonaut Alexander Misurkin, left Earth at 5:17 p.m. EDT to head toward the International Space Station (@iss) for a five-month stay. They will arrive at their new home in space at 10:57 p.m.
There are currently three people living on the space station, soon to be joined by the three crew members that launched today. While living on this unique orbiting platform, they conduct important research and science that will not only help us travel deeper into space, but also benefits life here on Earth.

Like firecrackers lighting up the sky on New Year’s Eve, the majestic spiral arms of this galaxy are alight with new stars being born. The Hubble Space Telescope (@NASAHubble) saw this spiral galaxy, NGC 5559, with spiral arms filled with gas and dust sweeping out around the bright galactic bulge. These arms are a rich environment for star formation, dotted with a festive array of colors including the newborn stars glowing blue as a result of their immensely high temperatures.

NGC 5559 was discovered by astronomer William Herschel in 1785 and lies approximately 240 million light-years away in the northern constellation of Boötes (the herdsman). Credit: ESA/Hubble & NASA

Astronaut Randy 'Komrade' Bresnik (@AstroKomrade) shared this image of Hurricane Irma this evening saying "The tentacles of the bow wave of #Irma clawing its way up Florida." Bresnik is currently living and working in space on the International Space Station (@ISS). Hurricane Irma formed in the Atlantic Ocean and has affected the Caribbean, including Puerto Rico and the U.S. Virgin Islands, before impacting the United States. Our fleet of satellites have been continually providing forecasters with data on Hurricane Irma. That includes satellite imagery for Irma, plus trajectory, force and precipitation tracking to inform the National Hurricane Center.

Explore Saturn's rings like never before with the highest-resolution color images ever taken by our Cassini mission. This image shows a portion of the inner-central part of the planet's B Ring and is a mosaic of two images that show a region that lies between 61,300 and 65,600 miles (98,600 and 105,500 km) from Saturn's center.

This image is a natural color composite, created using images taken with red, green and blue spectral filters. The pale tan color is generally not perceptible with the naked eye in telescope views, especially given that Saturn has a similar hue.

The material responsible for bestowing this color on the rings -- which are mostly water ice and would otherwise appear white -- is a matter of intense debate among ring scientists that will hopefully be settled by new in-situ observations before the end of Cassini's mission.
