Get Down to Earth This Year With Globe-Spanning Expeditions: We're sending scientists around the world in 2016 – from the edge of the Greenland ice sheet to the coral reefs of the South Pacific – to delve into challenging questions about how our planet is changing and what impacts humans are having on it. While Earth science field experiments are nothing new for us, the next six months will be a particularly active period with eight major new campaigns taking researchers around the world on a wide range of science investigations. The public is invited to follow this journey of exploration online through our social media channels and the new Earth Expeditions webpage, which will feature regular video, photos and blog posts from these missions and other ongoing field activities.

Twas the night before launch, and everything is progressing towards the liftoff of Orbital ATK's Cygnus spacecraft to the International Space Station. The mission is set to launch on a ULA Atlas V rocket on Tuesday, March 22, from Space Launch Complex 41 at Cape Canaveral Air Force Station in Florida. The 30 minute launch window opens at 11:05 p.m. EDT. The L-1 forecast shows a 90 percent chance of favorable weather conditions for launch. A new 3D printer and research projects examining everything from adhesive technologies to the behavior of large fires in space are packed inside Cygnus.

Astronomers using the unique ultraviolet capabilities of the Hubble Space Telescope have identified nine monster stars with masses over 100 times the mass of the sun in the star cluster R136. The young and dense star cluster R136 can be seen at the lower right of this image showing the central region of the Tarantula Nebula in the Large Magellanic Cloud. This cluster contains hundreds of young blue stars, among them the most massive star detected in the universe so far. This makes it the largest sample of very massive stars identified to date.

And Liftoff! NASA astronaut Jeff Williams (@astro_jeffw) is now the first American to become a three-time, long-term resident of the International Space Station (@ISS). He arrived at the orbiting laboratory at 11:09 p.m. EDT Friday, with cosmonauts Alexey Ovchinin and Oleg Skripochka of the Russian space agency Roscosmos, where they will continue important research that advances NASA's Journey to Mars. The trio launched aboard a Soyuz TMA-20M spacecraft from the Baikonur Cosmodrome in Kazakhstan at 5:26 p.m. (3:26 a.m. Saturday, March 19, Baikonur time), orbited Earth four times, and docked at the station. The hatches between the spacecraft and station opened at 12:55 a.m. Saturday, March 19. Photo Credit: NASA/Aubrey Gemignani #nasa #iss #space #spacestation #iss;

Happy St. Patrick’s Day! Ireland is seen here from the International Space Station on a moonlit night under an amazing and ever-changing green aurora. This image was taken by NASA astronaut Terry Virts on Feb. 6, 2015. Also seen here are the United Kingdom and Scandinavia.

Picturing the Sun's Magnetic Field: This illustration lays a depiction of the sun's magnetic fields over an image captured by our Solar Dynamics Observatory on March 12. The complex overlay of lines can teach scientists about the ways the sun's magnetism changes in response to the constant movement on and inside the sun. Note how the magnetic fields are densest near the bright spots visible on the sun - which are magnetically strong active regions - and many of the field lines link one active region to another.

Tilted Terminator: When viewed with north pointing up, as in this image, the day-night boundary line (or terminator) cuts diagonally across Enceladus, with Saturn approaching its northern summer solstice. The lit portion on all of Saturn's large, icy moons, including Enceladus (313 miles or 504 kilometers across) and Saturn itself, is now centered on their northern hemispheres. This change of season, coupled with a new spacecraft trajectory, has progressively revealed new terrains compared to when Cassini arrived in 2004, when the southern hemisphere was more illuminated. This view captured by NASA's Cassini Mission to Saturnshows wrinkled plains that are remarkably youthful in appearance, being generally free of large impact craters.

Moon shot! Flying 250 miles above the Earth and traveling at 17,500 mph aboard the International Space Station, astronaut Tim Kopra snapped this photo of the moon and Earth and posted it before heading off to sleep Friday night. The station is a unique place - a convergence of science, technology and human innovation that demonstrates new technologies and makes research breakthroughs not possible on Earth. It is a microgravity laboratory where an international crew live and work while orbiting our planet every 90 minutes. Image Credit: NASA #nasa #iss #spacestation #earth #moon; -
Feeling small? Here's a legion of galaxies! Peering deep into the early universe, this picturesque observation from the Hubble Space Telescope reveals thousands of colorful galaxies swimming in the inky blackness of space. A few foreground stars from our own galaxy, the Milky Way, are also visible. Containing countless galaxies of various ages, shapes and sizes, this observation is nearly as deep as the Hubble Ultra-Deep Field. In addition to showcasing the stunning beauty of the deep universe in incredible detail, this parallel field - when compared to other deep fields - will help astronomers understand how similar the universe looks in different directions.

Galaxy clusters are enormous collections of hundreds or even thousands of galaxies and vast reservoirs of hot gas embedded in massive clouds of dark matter, invisible material that does not emit or absorb light but can be detected through its gravitational effects. These cosmic giants are not merely novelties of size or girth - rather they represent pathways to understanding how our entire universe evolved in the past and where it may be heading in the future. To learn more about clusters, including how they grow via collisions, astronomers have used some of the world's most powerful telescopes, looking at different types of light. They have focused long observations with these telescopes on a half dozen galaxy clusters. The name for this galaxy cluster project is the "Frontier Fields". Here is one of these Frontier Fields galaxy clusters, featured in a multi-wavelength image. One of the most complex and distorted galaxy clusters known, it is the site of a collision between four clusters. It is located about 5.4 billion light years away from Earth.

While residents of islands and nations in the Western Pacific looked up in the early morning hours to observe a total eclipse of the Sun, the DSCOVR mission looked down from space and captured the shadow of the Moon marching across Earth’s sunlit face. This animation was assembled from 13 images acquired on March 9, 2016, by NASA’s Earth Polychromatic Imaging Camera (EPIC), a four-megapixel charge-coupled device and Cassegrain telescope on the DSCOVR satellite.

Solar Eclipse Over the South Pacific Ocean: During the afternoon of March 9, 2016, a total solar eclipse was visible in parts of southeast Asia and a partial eclipse was visible in parts of Alaska, Hawaii, Guam, and America Samoa. An eclipse occurs when the moon passes directly between Earth and the sun. When the moon's shadow falls on Earth, observers within that shadow see the moon block a portion of the sun's light. Our Aqua satellite captured this image of the total solar eclipse moving across the south Pacific Ocean at 03:05 UTC on March 9, 2016.

Wow, a total solar eclipse! See the moon pass directly in front of the sun. It happened from 8:38 to 8:42 p.m. EST Tuesday. As the moon passed precisely between the sun and Earth - a relatively rare occurrence that happens only about once a year because of the fact that the moon and the sun do not orbit in the exact same plane - it blocked the sun's bright face, revealing the tenuous and comparatively faint solar atmosphere, the corona. The total eclipse was only visible in parts of Southeast Asia. Credit: NASA #nasa #space #earth #moon #sun #astronomy #eclipse #solareclipse #eclipse2016 #science; -
Behold, the mountain Ahuna Mons on dwarf planet Ceres! From afar, Ahuna Mons looked to be pyramid-shaped, but upon closer inspection, it is best described as a dome with smooth, steep walls. This side-perspective view of the mysterious mountain was taken by our Dawn spacecraft's lowest-altitude orbit of Ceres. This mountain is about 3 miles (5 kilometers) high on its steepest side. Its average overall height is 2.5 miles (4 kilometers). Credits: NASA/JPL-Caltech/UCLA/MPS/DLR/IDA #nasa #ceres #nasadawn #astronomy #space #science;
