Summer Vacation: NASA astronaut Scott Kelly and his Russian crewmates Gennady Padalka and Mikhail (Misha) Kornienko took a road trip of sorts from the International Space Station after a little more than five months of their stay. They left their orbital home for a 20-minute get away to move their spacecraft. They undocked their Soyuz that brought them to the space station back in late March from one International Space Station module to another, clearing a module for the arrival of a new crew. It's the first time in nearly two years since nine crew members are aboard the station simultaneously. It's a full house.

Peering into the Heart of a Galactic Maelstrom: This Hubble Space Telescope image shows a spiral galaxy just over 35 million light-years away in the constellation of Leo (The Lion). It is of about the same mass and size as the Milky Way. The galaxy resembles a giant maelstrom of glowing gas, rippled with dark dust that swirls inwards towards the nucleus. Messier 96 is a very asymmetric galaxy; its dust and gas are unevenly spread throughout its weak spiral arms, and its core is not exactly at the galactic center. Its arms are also asymmetrical, thought to have been influenced by the gravitational pull of other galaxies within the same group.

At Saturn, One of These Rings is not like the Others: When the sun set on Saturn's rings in August 2009, scientists on our Cassini mission were watching closely. It was the equinox -- one of two times in the Saturnian year when the sun illuminates the planet's enormous ring system edge-on. The event provided an extraordinary opportunity for the orbiting Cassini spacecraft to observe short-lived changes in the rings that reveal details about their nature. In a recent study, a team of Cassini scientists reported that one section of the rings appears to have been running a slight fever during equinox. The higher-than-expected temperature provided a unique window into the interior structure of ring particles not usually available to scientists. This result is fascinating because it suggests that the middle of Saturn's A ring may be much younger than the rest of the rings. Other parts of the rings may be as old as Saturn itself.

The Pluto system as NASA’s New Horizons spacecraft saw it in July 2015. This animation, made with real images taken by New Horizons, begins with Pluto flying in for its close-up on July 14; we then pass behind Pluto and see the atmosphere glow in sunlight before the sun passes behind Charon. The movie ends with New Horizons’ departure, looking back on each body as thin crescents. Credit: NASA/JHUAPL/SwRI #nasa #pluto #plutoflyby #newhorizons #solarsystem #nasabeyond #science; -
Wings of a Butterfly: The cosmic butterfly is called the Twin Jet Nebula. The glowing and expanding shells of gas clearly visible in this image represent the final stages of life for an old star of low to intermediate mass. The star has not only ejected its outer layers, but the exposed remnant core is now illuminating these layers - resulting in a spectacular light show. The characteristic shape of the wings of the Twin Jet Nebula is most likely caused by the motion of two central stars around each other. It is believed that as the dying star and white dwarf orbit around their common center of mass, the ejected gas from the dying star is pulled into two lobes rather than expanding as a uniform sphere. Meanwhile the nebula's wings are still growing and, by measuring their expansion, astronomers have calculated that the nebula was created only 1,200 years ago.

Signs of Katrina Linger in the Marshes: Ten years after making landfall, scars from Hurricane Katrina still linger. And not just in the blighted houses that mar some neighborhoods. The marshes and swamps that buffer New Orleans from the Gulf of Mexico still show evidence of Katrine's wrath. The wetlands surrounding Delacroix, a fishing town to the southeast of New Orleans, were some of the hardest hit by the hurricane. Pounding surf, driving winds, and a potent storm surge transformed the marshes by picking apart mats of dead grass, stirring up and disbursing soft underlying sediments, scouring several new channels, and depositing leftover sediment and debris in new areas. Katrina delivered a massive surge of water that dramatically enlarged lakes, including Lake Lery and Petit Lake. It also scoured new channels and widened canals in ways that eliminated large amounts of marshland. As seen in the 2015 image, flood-damaged vegetation has returned to its normal color, but the enlarged waterways have persisted.

This star cluster, NGC 1783, is thought to be less than one and a half billion years old - which is very young for globular clusters, which are typically several billion years old. During that time, it is thought to have undergone at least two periods of star formation, separated by 50 to 100 million years. First observed by John Herschel in 1835, the cluster of stars is nearly 160,000 light-years from Earth, and has a mass around 170,000 times that of the sun. Globular clusters are dense collections of stars held together by their own gravity, which orbit around galaxies like satellites. The image clearly shows the symmetrical shape of NGC 1783 and the concentration of stars towards the center, both typical features of globular clusters.

With the ability to now send vertical images, we want to show you the world. Here's a look at the Earth from the International Space Station (@ISS) shared by European Astronaut Samantha Cristoforetti. When she shared this view from orbit 250 miles up, she wished everyone "Good night from space" in English & Italian on May 14, 2015.

We are explorers. Our vision is to reach for new heights and reveal the unknown so that what we do and learn will benefit all humankind. And for over 25 years, our Hubble Space Telescope has been revealing the unknown cosmos. Hubble is peering into the farthest reaches of the universe and back to its earliest moments of existence, helping us understand the universe's origin, evolution and destiny. Hubble continues to explore as we develop its successor, the James Webb Space Telescope, which will capture light from the universe's earliest stars.

Astronomers have found evidence for a faded electron cloud “coming back to life,” much like the mythical phoenix, after two galaxy clusters collided. This “radio phoenix,” so-called because the high-energy electrons radiate primarily at radio frequencies, is found in Abell 1033. A galaxy cluster consists of hundreds or even thousands of individual galaxies, unseen dark matter, and huge reservoirs of hot gas that glow in X-ray light. This system is located about 1.6 billion light years from Earth. Astronomers think that the supermassive black hole close to the center of Abell 1033 erupted in the past. Streams of high-energy electrons filled a region hundreds of thousands of light years across and produced a cloud of bright radio emission. This cloud faded over a period of millions of years as the electrons lost energy and the cloud expanded. This new portrait of the radio phoenix is captured in this multiwavelength image of Abell 1033. X-rays from Chandra are in pink and radio data from the VLA are colored green. The background image shows optical observations from the SDSS.

Aboard the International Space Station (@ISS) this morning, Astronaut Kimiya Yui of the Japan Aerospace Exploration Agency (JAXA) successfully captured JAXA’s Kounotori 5 H-II Transfer Vehicle (HTV-5) at 6:28 a.m. EDT. The HTV-5 is delivering more than 8,000 pounds of equipment, supplies and experiments in a pressurized cargo compartment. The unpressurized compartment will deliver the 1,400-pound CALorimetric Electron Telescope (CALET) investigation, an astrophysics mission that will search for signatures of dark matter and provide the highest energy direct measurements of the cosmic ray electron spectrum. Astronaut Scott Kelly (@StationCDRKelly) shared this image of the HTV-5 and Canadarm2, which reached out and grappled the cargo spacecraft.

Looking Up at Mars Rover Curiosity (@MarsCuriosity) in 'Buckskin' Selfie: This low-angle self-portrait of our Curiosity Mars rover shows the vehicle at the site from which it reached down to drill into a rock target called "Buckskin" on lower Mount Sharp. The selfie combines several component images taken by Curiosity's Mars Hand Lens Imager (MAHLI) on Aug. 5, 2015, during the 1,065th Martian day, or sol, of the rover's work on Mars. For scale, the rover's wheels are 20 inches (50 centimeters) in diameter and about 16 inches (40 centimeters) wide. A close look reveals a small rock stuck onto Curiosity's left middle wheel (on the right in this head-on view). MAHLI is mounted at the end of the rover's robotic arm. For this self-portrait, the rover team positioned the camera lower in relation to the rover body than for any previous full self-portrait of Curiosity. This yielded a view that includes the rover's "belly." Credit: NASA/JPL-Caltech/MSSS #nasa #mls #mars #marscuriosity #space #planet #nasabeyond #selfie #science; -
Here we see the spectacular cosmic pairing of the star Hen 2-427 - more commonly known as WR 124 - and the nebula M1-67 which surrounds it. Both objects, captured here by the Hubble Space Telescope are found in the constellation of Sagittarius and lie 15,000 light-years away. The star Hen 2-427 shines brightly at the very center of this explosive image and around the hot clumps of surrounding gas that are being ejected into space at over 93,210 miles (150,000 km) per hour. Hen 2-427 is a Wolf-Rayet star, named after the astronomers Charles Wolf and Georges Rayet. Wolf-Rayet are super-hot stars characterized by a fierce ejection of mass. The nebula M1-67 is estimated to be no more than 10,000 years old - just a baby in astronomical terms - but what a beautiful and magnificent sight it makes.
