And liftoff! The SpaceX Falcon 9 rocket launched at 1:42 p.m. EST Sunday from Vandenberg Air Force Base in California with the Jason-3 spacecraft onboard. The spacecraft's solar arrays are out, it is power positive and engineers are beginning to send it commands. Jason-3, an international mission led by the National Oceanic and Atmospheric Administration (NOAA), will help continue U.S.-European satellite measurements of global ocean height changes.

Space Flower! NASA astronaut Scott Kelly (@stationcdrkelly), who took over care of the zinnias aboard the space station (@ISS) after the plants weren't thriving from growing procedures on the ground, such as scheduled watering days. Kelly told the ground team., “You know, I think if we’re going to Mars, and we were growing stuff, we would be responsible for deciding when the stuff needed water. Kind of like in my backyard, I look at it and say ‘Oh, maybe I should water the grass today.’ I think this is how this should be handled.” And so, Kelly became an autonomous gardener aboard the space station. Today, the zinnias are thriving! Image Credit: NASA #nasa #space #gardening #flowers #zinnias #iss #spacestation #botany #journeytomars #science #yearinspace; -
[Artist Concept] In a far-off galaxy, 12.4 billion light-years from Earth, a ravenous black hole is devouring galactic grub. Its feeding frenzy produces so much energy, it stirs up gas across its entire galaxy. This artist's rendering shows the galaxy. It is the most luminous galaxy known. That means that it has the highest power output of any galaxy in the universe, and would appear to shine the brightest if all galaxies were at the same distance from us.

'Out over the blue,' wrote astronaut Scott Kelly (@stationcdrkelly) when posted this image to social media. Kelly is living and working off the Earth, for the Earth aboard the space station (@ISS) for a yearlong mission. Traveling the world about 250 miles above the Earth, and at 17,500 mph, he circumnavigates the globe more than a dozen times a day.

Mighty Saturn! It is easy to forget just how large Saturn is, at around 10 times the diameter of Earth. And with a diameter of about 72,400 miles (116,500 kilometers), the planet simply dwarfs its retinue of moons. One of those satellites, Tethys (660 miles or 1,062 kilometers across), is seen here at lower right. This view looks toward the sunlit side of the rings from about 8 degrees above the ring plane. The image was taken with the Cassini spacecraft wide-angle camera on March 7, 2015 using a spectral filter that preferentially admits wavelengths of near-infrared light centered at 752 nanometers.

A Supermassive and Super-hungry Galaxy: This Hubble Space Telescope image shows a spiral galaxy, located over 65 million light-years away. The galaxy's orientation clearly reveals the galaxy's striking spiral structure: a flat and dust-mottled disk surrounding a bright galactic bulge. Its glowing center hosts a gigantic version of a black hole, known as a supermassive black hole. The presence of a black hole in a distant galaxy like this can be inferred from its effect on the galaxy's innermost stars; these stars experience a strong gravitational pull from the black hole and whizz around the galaxy's center much faster than otherwise. Its galactic core is not just supermassive, but also super-hungry. In 2013 researchers were observing another galaxy when they noticed a violent flare at the center. The flare came from the central black hole tearing up and feeding off an object many times more massive than Jupiter. A brown dwarf or a large planet simply strayed too close and was devoured by the hungry core of NGC 4845. Image credit: ESA/Hubble & NASA and S.

Behold the most massive young galaxy cluster found in the early universe! Astronomers have used data from three of our Great Observatories to make the most detailed study yet of an extremely massive young galaxy cluster. This rare cluster, which is located 10 billion light years from Earth, weighs as much as 500 trillion suns. This object has important implications for understanding how these megastructures formed and evolved early in the universe. This cluster is so far away that the light detected is from when the universe was roughly a quarter of its current age. It is the most massive galaxy cluster detected at such an early age.

"Twins" of Superstar Eta Carinae in Other Galaxies: Eta Carinae, the most luminous and massive stellar system within 10,000 light-years, is best known for an enormous eruption seen in the mid-19th century that hurled at least 10 times the sun's mass into space. This expanding veil of gas and dust, which still shrouds Eta Carinae, makes it the only object of its kind known in our galaxy. Now a study using archival data from our Spitzer and Hubble space telescopes has found five objects with similar properties in other galaxies for the first time.

A Supermassive Black Hole Found Burping Nearby: Astronomers have used our Chandra X-ray Observatory to discover one of the nearest supermassive black holes to Earth that is currently undergoing powerful outbursts. This galactic burping was found in the Messier 51 galaxy, which is located about 26 million light years from Earth and contains a large spiral galaxy NGC 5194 (also known by its nickname of the "Whirlpool"), merging with a smaller companion galaxy NGC 5195 Image credit: X-ray: NASA/CXC/Univ of Texas/E.Schlegel et al; Optical: NASA/STScI #nasa #space #chandra #galaxy #blackhole #nasabeyond #science;

Our Curiosity Mars rover rounds Martian dune to get to the other side. Curiosity, partway through the first up-close study ever conducted of extraterrestrial sand dunes, is providing dramatic views of a dune's steep face, where cascading sand has sculpted very different textures than the wavy ripples visible on the dune's windward slope. This Dec. 18, 2015, view of the downwind face of "Namib Dune" on Mars covers 360 degrees, including a portion of Mount Sharp on the horizon.

Enceladus looks as though it is half lit by sunlight in this view from NASA's Cassini spacecraft, but looks can be deceiving. The area on the right, where surface features can be made out, are actually illuminated by light reflected off of Saturn. A sliver of surface illuminated by direct sunlight is visible on the left. Images like this one are designed to capture the extended plume of icy material spraying from the moon's south polar region. Such images need to be taken with Cassini looking toward the icy moon's night side, since the small particles in the plume are most easily seen when backlit by the sun. This view looks toward the leading hemisphere of Enceladus and was taken in visible light with Cassini's narrow-angle camera on May 10, 2015. Enceladus is 313 miles (504 kilometers) across.

What a year! In 2015, we explored the expanse of our solar system and beyond, and the complex processes of our home planet, while also advancing the technologies for our journey to Mars, and new aviation systems as we reached new milestones aboard the International Space Station (@ISS). The work we do, and will continue in 2016, helps the United States maintain its world leadership in space exploration and scientific discovery. We will continue investing in our journey to Mars, returning human spaceflight launches from American soil, fostering groundbreaking technology development, breakthroughs in aeronautics and bringing to every American the awe-inspiring discoveries and images captured by NASA’s missions in our solar system and beyond. #nasa #science #space #explore #discover #understand #solarsystem #planet #astronaut #2015 #2016 #happynewyear #spacestation; -
Two become one in this Hubble Space Telescope view showing galaxy NGC 6052, located around 230 million light-years away in the constellation of Hercules. It would be reasonable to think of this as a single abnormal galaxy, and it was originally classified as such. However, it is in fact a “new” galaxy in the process of forming. Two separate galaxies have been gradually drawn together, attracted by gravity, and have collided. We now see them merging into a single structure. As the merging process continues, individual stars are thrown out of their original orbits and placed onto entirely new paths, some very distant from the region of the collision itself. Since the stars produce the light we see, the “galaxy” now appears to have a highly chaotic shape. Eventually, this new galaxy will settle down into a stable shape, which may not resemble either of the two original galaxies.
