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.

This galaxy cluster is home to one of the most powerful eruptions ever observed! X-rays detected by our Chandra X-Ray Observatory (blue) show the hot gas that comprises much of the mass of this enormous object. Within the Chandra data, holes, or cavities, can be seen. These cavities were created by an outburst from a supermassive black hole at the center of the cluster, which ejected the enormous jets detected in radio waves (pink) detected by the Very Large Array. These data have been combined with optical data from the Hubble Space Telescope of galaxies in the cluster and stars in the field of view (orange).

We unveiled mosaics of Pluto and its largest moon Charon, representing the global response to its popular "#PlutoTime" social media campaign. ThePluto Time concept and widget was developed by the New Horizons science team so that people could experience the approximate sunlight level on Pluto at noon-generally around dawn or dusk on Earth. Thousands of those submissions have now been assembled into three stunning mosaics of Pluto, Charon, and a combined image of the two. The mosaics include not only dim skies on Earth, but famous landmarks, selfies, and even family pets.

Repost from @WhiteHouse: This view of the International Space Station is a composite of nine frames that captured the @ISS transiting the moon at roughly five miles per second on August 2. 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. As the third brightest object in the sky, the International Space Station is easy to see if you know when to look up. You can sign up for alerts and get information on when the International Space Station flies over you at spotthestation.nasa.gov. Thanks for following along today as @NASA shared the view from #AstronomyNight at the White House. Remember to look up and stay curious!; -
Repost from @whitehouse: This incredible look at the Cat’s Eye nebula was taken from a composite of data from @NASA's Chandra X-ray Observatory and Hubble Space Telescope. This famous object is a so-called planetary nebula that represents a phase of stellar evolution that the Sun should experience several billion years from now. When a star like the Sun begins to run out of fuel, it becomes what is known as a red giant. In this phase, a star sheds some of its outer layers, eventually leaving behind a hot core that collapses to form a dense white dwarf star. A fast wind emanating from the hot core rams into the ejected atmosphere, pushes it outward, and creates the graceful filamentary structures seen with optical telescopes. #AstronomyNight; -
Repost from @whitehouse: Take a look at the millions of galaxies that populate the patch of sky known as the COSMOS field, short for Cosmic Evolution Survey. A portion of the COSMOS field is seen here by @NASA's Spitzer Space Telescope. Even the smallest dots in this image are galaxies, some up to 12 billion light-years away. The picture is a combination of infrared data from Spitzer (red) and visible-light data (blue and green) from Japan's Subaru telescope atop Mauna Kea in Hawaii. The brightest objects in the field are more than ten thousand times fainter than what you can see with the naked eye. #AstronomyNight;
