View these celestial beauties taken by the Hubble Space Telescope (@NASAHubble) and released as a set of modern views of the "Messier Catalog." Spotting comets was all the rage in the middle of the 18th century, and at the forefront of the comet hunt was a young French astronomer named Charles Messier. In 1774, in an effort to help fellow comet seekers steer clear of astronomical objects that were not comets (something that frustrated his own search for these elusive entities), Messier published the first version of his “Catalog of Nebulae and Star Clusters,” a collection of celestial objects that weren’t comets and should be avoided during comet hunting. Today, rather than avoiding these objects, many amateur astronomers actively seek them out as interesting targets to observe with backyard telescopes, binoculars or sometimes even with the naked eye. Hubble’s version of the Messier catalog includes eight newly processed images never before released by NASA. The images were extracted from more than 1.3 million observations that now reside in the Hubble data archive. Some of these images represent the first Hubble views of the objects, while others include newer, higher resolution images taken with Hubble’s latest cameras.

I’ve got sunshine….on a spacewalking day! During this month’s second of three spacewalks, NASA astronauts Randy Bresnik (@AstroKomrade) and Mark Vande Hei were welcomed with a beautiful sunrise. Bresnik posted this image to his social accounts saying, “A glorious sunrise greeted [astronaut Mark Vande Hei] and I at the start of our 2nd #spacewalk. His visor reflection shows the airlock hatch we came out”. During this spacewalk, Bresnik and Vande Hei lubricated parts of the station’s robotic arm, replaced a smudged lens cover on an exterior camera and removed two handrails in preparation for a future wireless antenna installation. Currently, there are six people living and working on the International Space Station (@iss). During their stay on the orbiting laboratory, they conduct important science and research that will not only help life here on Earth, but will aid our journey deeper into space. Tune in for the third of three spacewalks this month on Friday, Oct. 20 at 6:30 a.m. EDT. You can watch live as two astronauts venture outside the space station at Credit: NASA #nasa #space #spacewalk #sun #sunrise #spacestation #astronaut #astronauts #earth #hatch #picoftheday #research #science #repair

Round and round they go - then BOOM! This animation begins with the final moments of two neutron stars (the super-dense cores of exploded massive stars), whirling around each other in a galaxy 130 million light-years away. Gravitational waves (rippling disturbance in space-time, shown here as pale arcs) bleed away orbital energy, causing the stars to move closer together and merge. As the stars collide, this explosive event emits light across a series of different wavelengths - first gamma rays (magenta), then ultraviolet (violet), then visible and infrared (blue-white to red) and once the jet directed toward us expanded into our view from Earth, X-rays (blue). Our Fermi Gamma-Ray Space Telescope witnessed this event on August 17, 2017 and we watched it unfold over multiple days with a variety of other telescopes, including the Swift spacecraft, the Hubble Space Telescope (@NASAHubble), the Spitzer Space Telescope, our Chandra X-Ray Observatory (@NASAChandraXray) and our NuSTAR mission. The detectors at the Laser Interferometer Gravitational-Wave Observatory (LIGO) received a gravitational wave signal just 1.7 seconds before the first light was seen by Fermi, making this the first event observed in both light and gravitational waves.

As far as galaxies are concerned, size can be deceptive. Some of the largest galaxies in the Universe are dormant, while some dwarf galaxies, such as the one imaged here by the Hubble Space Telescope (@NASAHubble), can produce stars at a hair-raising rate. In fact, this galaxy has one of the highest rates of star formation of the 1,000 or so galaxies nearest to the Milky Way! Clusters of young, hot stars are speckling the galaxy, burning with a fierce blue glow. The intense radiation they produce also causes surrounding gas to light up, which is bright red in this image.

Today we’re celebrating the 70th anniversary of supersonic flight, which is faster than the speed of sound! For 70 years, barriers have been broken as planes loudly flew supersonic. Now, we’re working to make history again in a quieter, revolutionary way. Our supersonic research has brought us ever closer to making commercial supersonic flight over land a reality. That would mean you could travel from New York to Los Angeles in 2 hours. These efforts have dealt with research in several areas, including the use of cutting-edge visualization technology to study shockwaves, the use of F-15 aircraft to examine methods for improved cruise efficiency, the integration of displays to help pilots monitor the audial effects of supersonic flight and the impacts of the environment on sonic booms.

Dawn brings the sight of Dream Chaser, Sierra Nevada Corporation’s reusable spacecraft, as it sits on the runway at our Armstrong Flight Research Center (@nasaarmstrong) where it’s being tested and prepped to deliver cargo to the International Space Station (@iss) under a Commercial Resupply Services (CRS-2) contract. The data gathered from this test campaign will help influence and inform the final design of the cargo Dream Chaser, which will fly at least six cargo delivery missions to and from the space station by 2024. Commercial Resupply Services contracts are designed to obtain cargo delivery services to the space station, disposal of unneeded cargo, and the return of research samples and other cargo from the station back to Earth. In 2016, three cargo contracts were awarded to Orbital ATK of Dulles, Virginia (@Orbital_ATK); Sierra Nevada Corporation of Sparks, Nevada (@SierraNevCorp); and SpaceX of Hawthorne, California (@SpaceX). These recipients will ensure the critical science, research and technology demonstrations that are informing our journey to Mars are delivered to the International Space Station from 2019 through 2024.

Goodbye to the dark side. Stunning views like this image of Saturn’s night side are only possible thanks to our robotic emissaries like the Cassini spacecraft. The Cassini mission ended its 13 year journey at Saturn on Sept. 15 with a fateful dive into the planet’s atmosphere. Until future missions are sent to the ringed planet, Cassini’s image-rich legacy must suffice. Because Earth is closer to the Sun than Saturn, observers on Earth only see Saturn’s day side. With spacecraft, we can capture views – and data – that are simply not possible from Earth, even with the largest telescopes.

Can you find the two tiny humans among the vastness of space in this image from yesterday’s spacewalk? Hint: They’re wearing white and only the legs and feet of one of them can be seen. Early yesterday morning, astronauts Randy Bresnik (@AstroKomrade) and Mark Vande Hei ventured outside the International Space Station (@iss) for 6 hours and 26 minutes to perform maitenance on the robotic arm used to capture visiting spacecraft and other objects. They sucessfully completed all planned tasks and even had time to acomplish a few get-ahead items, like replacing a smudged lens cover on an external camera and removing two handrails from outside one of the station’s modules. Currently, six people are living and working on the orbiting laboratory, conducting important science and research that will not only benefit life here on Earth, but will help us venture deeper into space than ever before.

Parts of northern California have been ravaged by intense and fast-burning wildfires that broke out on October 8. Blazes that started on a few hundred acres around Napa Valley were fanned by strong northeasterly winds, and by October 10, the 14 fires had consumed as much as 100,000 acres of land. NASA Earth observing satellites capture images of the fires from their unique vantage point in space. States of emergency have been declared in Napa, Sonoma, Yuba, and Mendocino counties, and thousands of people were asked to evacuate. The densely populated “wine country” is famous for its vineyards and wine-making operations and the tourists they attract.

Shadowed by the grandeur of Jupiter (@nasajuno), two of the planet’s largest moons – Io and Europa – are seen here in this image captured by our Juno spacecraft on Sept. 1. At the time the image was taken, the spacecraft was about 17,098 miles from the cloud tops of the planet. Closer to the planet, the Galilean moon of Io can be seen. In the distance (to the left), another on of Jupiter’s Galilean moons, Europa, is visible.

Over a 17-hour period, a pair of active regions – with solar plasma heated to over a million degrees – rotated into our Solar Dynamic Observatory’s view Oct. 4-5. They were observed in a wavelength of extreme ultraviolet light. The arches above the regions consist of charge particles spinning along and revealing magnetic field lines. Each one shows a few minor bursts of material, none of which were serious. Credit: NASA #nasa #space #sun #SUNday #picoftheday #solarsystem #universe #yellow #light #magnetic #plasma #hot

Stacked “bubbles” of the so-called Honeycomb Nebula are seen here among spindly, spidery filaments of gas in the Tarantula Nebula. These bubble-like shapes are likely only seen because of the Hubble Space Telescope’s (@nasahubble) unique viewpoint. At a distance of 160,000 light-years, the Large Magellanic Cloud – which is home to these “bubbles” – is one of the Milky Way’s closest companions. It is also home to one of the largest and most intense regions of active star formation known to exist anywhere in our galactic neighborhood – the Tarantula Nebula.

Suited Up for a Day's Work: Astronaut Randy Bresnik (@AstroKomrade) is seen wearing his spacewalking suit, an Extravehicular Mobility Unit, during an October 5 spacewalk to replace a degraded robotic arm "hand," called the Latching End Effector, on the tip of the International Space Station's (@ISS) robotic arm, the Canadarm2. This was the first of three spacewalks planned for October. The second and third spacewalks will be devoted to lubricating the newly installed end effector and replacing cameras on the left side of the space station’s truss and the right side of the station’s U.S. Destiny laboratory.

Once every 53 days, our Juno spacecraft swings close to Jupiter, speeding over its clouds. In just two hours, Juno travels from a perch over Jupiter’s north pole through its closest approach, then passes over the south pole on its way back out. This sequence shows color-enhanced images from its 8th close pass on Sept. 1, 2017, with the south pole on the left (last image in the sequence) and the north pole on the right (first image in the sequence). Swipe to explore the sequence of images. Image Credits: NASA/JPL-Caltech/SwRI/MSSS/Kevin M.

Fish-eye view of planet Earth. NASA astronaut Randy Bresnik (@astrokomrade) captured this timelapse video from his unique vantage point on the International Space Station (@iss) , 250 miles above our home planet. He posted it to his social media accounts on Oct. 1 saying, “Desert sands, wispy clouds, and blue ocean, the cupola fish-eye spies many features along the spine of Africa in this #timelapse.” There are currently six people living and working on the space station, which is orbiting our planet at 17,500 mph. They are conducting important science and research on the orbiting laboratory that will not only help us send humans to deep space destinations, like Mars, but also has direct benefits to live here on Earth.
