Whopping Galaxy Cluster Spotted: Astronomers have discovered a giant gathering of galaxies in a very remote part of the universe, thanks to our Spitzer Space Telescope and Wide-field Infrared Survey Explorer (WISE). This galaxy cluster, located 8.5 billion light-years away, is the most massive structure yet found at such great distances. Galaxy clusters are gravitationally bound groups of thousands of galaxies, which themselves each contain hundreds of billions of stars. The clusters grow bigger and bigger over time as they acquire new members. The red galaxies at the center of the image make up the heart of the galaxy cluster. This color image is constructed from multi-wavelength observations: Infrared observations from NASA's Spitzer Space Telescope are shown in red; near-infrared and visible light is green and blue; and radio light is purple. In addition to galaxies, clusters also contain a reservoir of hot gas with temperatures in the tens of millions of degrees Celsius/Kelvin.

A milestone of human achievement, people have lived off the planet continuously for 15 years aboard the International Space Station (@ISS). Think about it, a teenager doesn't know a world where humans haven't lived and worked in space. Since Nov. 2, 2000, NASA astronauts and our international partners work off the Earth, for the Earth. From 1998 to 2011, five different space agencies representing 15 countries assembled the station, the largest structure ever built in space. Since being occupied in 2000, we've conducted more than 1,760 research investigations on the orbiting laboratory and more than 220 people from 17 countries have visited.

For 15 years, since Nov. 2, 2000, there has been a continuous human presence on the International Space Station (@ISS) orbiting Earth in space, as NASA astronauts and their international partners work off the Earth, for the Earth. From 1998 to 2011, five different space agencies representing 15 countries assembled the station, the largest structure ever built in space. Since being occupied in 2000, we've conducted more than 1,760 research investigations on the orbiting laboratory and more than 220 people from 17 countries have visited. In this image is NASA astronaut Tracy Caldwell Dyson taking a moment during her space station mission in 2010 to enjoy an unmatched view of home through a window in the Cupola of the International Space Station, the brilliant blue and white part of Earth glowing against the blackness of space.

Smoke Ring for a Halo Two stars shine through the center of a ring of cascading dust in this image taken by the Hubble Space Telescope. The star system is named DI Cha, and while only two stars are apparent, it is actually a quadruple system containing two sets of binary stars. As this is a relatively young star system it is surrounded by dust. The young stars are molding the dust into a wispy wrap.

Happy Halloween! We present a solar 'pumpkin!' Active regions on the sun combined to look something like a jack-o-lantern’s face on October 2014. The image was captured by NASA's Solar Dynamics Observatory, or SDO, which watches the sun at all times from its orbit in space. The active regions in this image appear brighter because those are areas that emit more light and energy.

Halloween Skies to Include Dead Comet Flyby: The large space rock that will safely zip past Earth this Halloween is most likely a dead comet that, fittingly, bears an eerie resemblance to a skull. This image of asteroid 2015 TB145 was generated using radar data collected by the National Science Foundation's 1,000-foot (305-meter) Arecibo Observatory in Puerto Rico. The radar image was taken on Oct. 30, 2015, and the image resolution is 25 feet (7.5 meters) per pixel.

A Full View of Pluto's Stunning Crescent: In September, the New Horizons team released a stunning but incomplete image of Pluto's crescent. Thanks to new processing work by the science team, New Horizons is releasing the entire, breathtaking image of Pluto. This image was made just 15 minutes after New Horizons' closest approach to Pluto on July 14, 2015, as the spacecraft looked back at Pluto toward the sun. The backlighting highlights more than a dozen high-altitude layers of haze in Pluto's tenuous atmosphere. The horizontal streaks in the sky beyond Pluto are stars, smeared out by the motion of the camera as it tracked Pluto.

Astronaut Selfie from Space! Scott Kelly took this photograph during a spacewalk outside the space station Wednesday. Sharing the image on social media, Kelly wrote, "#SpaceWalkSelfie Back on the grid! Great first spacewalk yesterday. Now on to the next one next week. #YearInSpace." This was the first spacewalk for both Kelly and astronaut Kjell Lindgren. Today, Oct. 29, Kelly becomes the U.S. astronaut who has lived in space the longest during a single U.S. spaceflight, and on Monday, Nov. 2, the crew celebrates the 15th year of a continuous human presence in space aboard the station.

Deep Dive Through Enceladus Plume Complete (artist concept): Our Cassini spacecraft successfully completed its close flyby of Saturn's moon Enceladus today, passing 30 miles (49 kilometers) above the moon's south polar region at approximately 8:22 a.m. PDT (11:22 a.m. EDT). Mission controllers established two-way communication with the spacecraft this afternoon and expect it to begin transmitting data from the encounter this evening. Images are anticipated in the next 24 to 48 hours. Credits: NASA/JPL-Caltech (artist concept) #nasa #space #cassini #saturn #enceladus #nasabeyond #science; -
Astronaut Scott Kelly tries on his spacesuit on the International Space Station. Kelly and Flight Engineer Kjell Lindgren will venture outside the station for a pair of spacewalks, the first of their careers, on Wednesday, Oct. 28 and Friday, Nov. 6. The Oct. 28 spacewalk is set to last six hours and 30 minutes. It will be the 32nd U.S. spacewalk, and will focus on station upgrades and maintenance tasks. NASA TV coverage will begin at 6:30 a.m. EDT. Sharing this photograph of the spacesuit fit check with his social media followers, Kelly wrote, "Day 212 Getting my game face on for #spacewalk Thanks for sticking w me #GoodNight from @ISS! #YearInSpace" Image Credit: NASA #nasa #space #iss #spacestation #spacewalk #eva;

Enceladus is a world divided. To the north, the terrain is covered in impact craters, much like other icy moons. But to the south, the record of impact cratering is much more sparse, and instead the land is covered in fractures, ropy or hummocky terrain and long, linear features. The image was taken in visible green light with the Cassini spacecraft narrow-angle camera on July 27, 2015. The spacecraft will sample the ocean of Enceladus on Wednesday, Oct. 28, when it flies through the moon's plume of icy spray.

This image shows the galaxy Messier 94, which lies in the small northern constellation of the Hunting Dogs, about 16 million light-years away. Within the bright ring or starburst ring around Messier 94, new stars are forming at a high rate and many young, bright stars are present within it. The cause of this peculiarly shaped star-forming region is likely a pressure wave going outwards from the galactic center, compressing the gas and dust in the outer region. The compression of material means the gas starts to collapse into denser clouds. Inside these dense clouds, gravity pulls the gas and dust together until temperature and pressure are high enough for stars to be born.

Artist's conception of a hot Jupiter, previously thought to be lonely planets. Scientists have now discovered one hot Jupiter with two close companions, leading to new ideas about planet formation. Until now, some 300 hot Jupiters have been identified over the past two decades, and this is the first time any close-in planets were discovered. This new discovery is helpful to scientists who are trying to understand how planets form and move in solar systems.

Aboard the International Space Station, astronaut Scott Kelly (@stationcdrkelly) this photo today and wrote, 'Hurricane #Patricia looks menacing from @ISS. Stay safe below, #Mexico. #YearInSpace.' The National Hurricane Center said that Hurricane Patricia had grown into a monster hurricane. In fact, it is the strongest eastern north pacific hurricane on record. a Hurricane Warning was in effect from San Blas to Punta San Telmo. A Hurricane Watch was in effect from east of Punta San Telmo to Lazaro Cardenas and a Tropical Storm Warning was in effect from east of Punta San Telmo to Lazaro Cardenas.

Big Bang Frontiers: Observations have taken advantage of gravitational lensing to reveal the largest sample of the faintest and earliest known galaxies in the universe. Some of these galaxies formed just 600 million years after the big bang and are fainter than any other galaxy yet uncovered by the Hubble Space Telescope. The team has determined for the first time with some confidence that these small galaxies were vital to creating the universe that we see today.
