Unveiling a Tapestry of Dazzling Diamond-like Stars: Resembling an opulent diamond tapestry, this image from our Hubble Space Telescope shows a glittering star cluster that contains a collection of some of the brightest stars seen in our Milky Way galaxy. Called Trumpler 14, it is located 8,000 light-years away in the Carina Nebula, a huge star-formation region. Because the cluster is only 500,000 years old, it has one of the highest concentrations of massive, luminous stars in the entire Milky Way. The small, dark knot left of center is a nodule of gas laced with dust, and seen in silhouette. Credits: NASA, ESA, and J.

As a massive winter storm continues to pummel the U.S. East Coast early on January 23, 2016, International Space Station (@ISS) Commander Scott Kelly (@StationCDRkelly) shared this photograph from orbit showing the region below. He stated "Massive #snowstorm blanketing #EastCoast clearly visible from Space Station! Stay safe!" The International Space 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 in which an international crew of six people live and work while traveling at a speed of 17,500 mph, orbiting Earth every 90 minutes.

Blizzard Bears Down on U.S. East Coast: NASA and NOAA satellites are tracking the large winter storm that is expected to bring heavy snowfall to the U.S. mid-Atlantic region on Jan. 22 and 23. NASA-NOAA's Suomi NPP satellite snapped this image of the approaching blizzard around 2:35 a.m. EST on Jan. 22, 2016 using the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument's Day-Night band.

SpaceX recently tested its ability to fire engines that will be used to land a human-rated spacecraft safely on the ground with the accuracy of a helicopter at the company’s test facility in McGregor, Texas. SpaceX envisions returning people to Earth from space on the power of thrust instead of beneath parachutes. Working with our Commercial Crew Program, SpaceX is in the early phases of analysis. The Crew Dragon spacecraft will be equipped with eight SuperDraco thrusters that would be used to slow the vehicle’s return to Earth through the atmosphere and ultimately set the spacecraft and its crew down. Propulsive landing will not be used initially for missions with NASA astronauts to the International Space Station. The Crew Dragon will splash down safely in the ocean under parachutes as its passengers return from the space station. Credit: SpaceX #nasa #spacex #dragon #spacestation #iss #launchamerica;

Aurora and the Pacific Northwest: NASA astronaut Scott Kelly and ESA astronaut Tim Peake shared a series of aurora photographs taken from the International Space Station on Jan. 20, 2016. Kelly (@StationCDRKelly) wrote, "#goodmorning #aurora and the Pacific Northwest! #YearInSpace" and Peake (@astro_timpeake) followed up with, "Getting a photo masterclass from @StationCDRKelly - magical #aurora" The dancing lights of the aurora provide spectacular views on the ground, but also capture the imagination of scientists who study incoming energy and particles from the sun. Aurora are one effect of such energetic particles, which can speed out from the sun both in a steady stream called the solar wind and due to giant eruptions known as coronal mass ejections or CMEs.

A dark solar filament above the sun's surface became unstable and erupted this past December, generating a cascade of magnetic arches. A small eruption to the upper right of the filament was likely related to its collapse. The arches of solar material appear to glow as they emit light in extreme ultraviolet wavelengths, highlighting the charged particles spinning along the sun's magnetic field lines. This video was taken in extreme ultraviolet wavelengths of 193 angstroms, a type of light that is typically invisible to our eyes, but is colorized here in bronze.

This Hubble Space Telescope image shows us a "red and dead" elliptical galaxy -- the product of a collision between two good-sized galaxies that is slowly evolving to become a giant elliptical galaxy. Older ellipticals are nicknamed "red and dead" by astronomers because these bloated galaxies are not producing new, bluer stars, and are thus packed full of old and redder stellar populations. This type of galaxy has grown more and more common as the universe has evolved, with initially small galaxies merging and progressively building up into larger galactic structures over time.

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.

Before drifting off the sleep tonight aboard the International Space Station, astronaut Scott Kelly (@stationcdrkelly) posted this image and wrote, 'Day 287. Another week done with a flash of #lightning. #GoodNight from @ISS! #YearInSpace.' Kelly is living and working off the Earth, for the Earth aboard the station for a yearlong mission.
