Hubble Watched a Pulsating Stellar Relic: This NASA/ESA Hubble Space Telescope image shows the planetary nebula NGC 2452, located in the southern constellation of Puppis. The blue haze across the frame is what remains of a star like our sun after it has depleted all its fuel. When this happens, the core of the star becomes unstable and releases huge numbers of incredibly energetic particles that blow the star's atmosphere away into space.
At the center of this blue cloud lies what remains of the nebula's progenitor star. This cool, dim, and extremely dense star is actually a pulsating white dwarf, meaning that its brightness varies over time as gravity causes waves that pulse throughout the small star's body.
NGC 2452 was discovered by Sir John Herschel in 1847. He initially defined it as "an object whose nature I cannot make out. It is certainly not a star, nor a close double star [...] I should call it an oblong planetary nebula." To early observers like Herschel with their smaller telescopes, planetary nebulae resembled gaseous planets, and so were named accordingly. The name has stuck, although modern telescopes like Hubble have made it clear that these objects are not planets at all, but the outer layers of dying stars being thrown off into space.

High Above Saturn: This portrait looking down on Saturn and its rings was created from images obtained by NASA's Cassini spacecraft on Oct. 10, 2013. It was made by amateur image processor and Cassini fan Gordan Ugarkovic. This image has not been geometrically corrected for shifts in the spacecraft perspective and still has some camera artifacts.The mosaic was created from 12 image footprints with red, blue and green filters from Cassini's imaging science subsystem. Ugarkovic used full color sets for 11 of the footprints and red and blue images for one footprint.

Did The Sun Do a 360 While NASA Was Away?! Here's what the sun looked like while we were away. These images were captured from Oct. 1, 2013 through Oct. 17 by NASA's Solar Dynamics Observatory (SDO). On Oct. 2, the sun appears to spin completely around its axis, but of course it was really SDO that did the 360. SDO rolls around its axis twice a year to help calibrate one of three instruments aboard SDO -- the Helioseismic and Magnetic Imager. The roll helps scientists remove optical distortions from the images and so precisely determine the boundaries of the sun's horizon, or "limb". Accumulated over time, such data shows whether the sun's sphere changes in concert with the 11-year solar cycle, during which the sun moves through periods of greater and lesser activity as evidenced by the changing frequency of giant solar eruptions.

Astronaut Mike Hopkins, aboard the International Space Station, shared this picture of the northern lights on October 9, 2013 saying "The pic doesn't do the northern lights justice. Covered the whole sky. Truly amazing!" The northern lights are caused by collisions between fast-moving particles (electrons) from space and the oxygen and nitrogen gas in our atmosphere. These electrons originate in the magnetosphere, the region of space controlled by Earth’s magnetic field. As they rain into the atmosphere, the electrons impart energy to oxygen and nitrogen molecules, making them excited. When the molecules return to their normal state, they release photons, small bursts of energy in the form of light.
Astronauts have used hand-held cameras to photograph the Earth for more than 40 years. Beginning with the Mercury missions in the early 1960s, astronauts have taken more than 700,000 photographs of the Earth. Today, the International Space Station continues the NASA tradition of Earth observation from human-tended spacecraft.

We're sorry, but we will not be posting updates to Instagram during the government shutdown. Also, all public NASA activities and events are cancelled or postponed until further notice. We'll be back as soon as possible. Sorry for the inconvenience.;
Happy Birthday to us! NASA turns 55 tomorrow. As we begin our 56th year of operations, we're expanding commercial access to the International Space Station and developing a new rocket and spacecraft to send astronauts farther than ever, starting with a mission to a captured, relocated asteroid in the next decade. We're exploring off the Earth, for the Earth, unlocking mysteries of our solarsystem and peering back into the beginnings of the Universe, all while developing technologies to enable NASA's current and future missions and improve life right here on Earth.
Stick around. It could get even more interesting.

Full View of Asteroid Vesta! As NASA's Dawn spacecraft travels to its next destination, this mosaic synthesizes some of the best views the spacecraft had of the giant asteroid Vesta. Dawn studied Vesta from July 2011 to September 2012. The towering mountain at the south pole - more than twice the height of Mount Everest - is visible at the bottom of the image. The set of three craters known as the "snowman" can be seen at the top left.
Launched in 2007, Dawn orbited Vesta for more than a year, departing in September 2012. Dawn is now on its way to the dwarf planet Ceres and will arrive there in early 2015.

#Cygnus arrives at the #ISS! A week after its original approach date, Orbital Sciences’ commercial cargo craft Cygnus has arrived at the International Space Station. The Expedition 37 crew captured Cygnus with the Canadarm2 at 7 a.m. EDT Sunday. Cygnus launched Sept. 18 aboard an Antares rocket from NASA’s Wallops Flight Facility in Virginia.
In this image from NASA TV, the Cygnus commercial resupply craft is installed by the Canadarm2 to the Harmony node on the space station.
Orbital Sciences is the second company to send a commercial cargo craft to the space station.

Earthquake creates a new island: Off the coast of Pakistan, a new island rose from the seafloor on Tuesday. The “mud island” rose from the seafloor near Gwadar on September 24, shortly after a magnitude 7.8 earthquake rattled the Balochistan province of northwestern Pakistan. The Advanced Land Imager (ALI) on NASA’s Earth Observing-1 (EO-1) captured this image of a new island off the coast of Pakistan on September 26, 2013.
The Earth Observing-1 (EO-1) satellite is an advanced land-imaging mission that demonstrates new instruments and spacecraft systems. EO-1 was launched from Vandenberg Air Force Base, California on November 21, 2000.

Glow with the Flow: Researchers at NASA's Langley Research Center use all sorts of tools and techniques to learn more during the development of aircraft and spacecraft designs. In this photo, engineers led by researcher Greg Gatlin have sprayed fluorescent oil on a 5.8 percent scale model of a futuristic hybrid wing body during tests in the14 by-22-Foot Subsonic Wind Tunnel. The oil helps researchers "see" the flow patterns when air passes over and around the model. Those patterns are important in determining crucial aircraft characteristics such as lift and drag.

New Expedition 37 crew members Oleg Kotov, Mike Hopkins and Sergey Ryazanskiy were welcomed aboard the International Space Station Thursday at 12:34 a.m. EDT. They docked to the Poisk mini-research module Wednesday at 10:45 p.m. EDT aboard a Soyuz spacecraft, seen here in this image approaching the space station.
They launched just four orbits earlier at 4:58 p.m. from the Baikonur Cosmodrome, Kazakhstan. After the hatches opened the new residents were greeted by Expedition 37 Commander Fyodor Yurchikhin and Flight Engineers Karen Nyberg and Luca Parmitano.
Kotov, Hopkins and Ryazanskiy are scheduled for a 5-1/2 month stay in space living and working inside the orbital laboratory. They are due to return home in March 2014 landing in Kazakhstan inside the same Soyuz spacecraft they arrived in.

Launch photo! The Soyuz rocket lifted off from the Baikonur Cosmodrome in Kazakhstan on today carrying Expedition 37 Soyuz Commander Oleg Kotov, NASA Flight Engineer Michael Hopkins and Russian Flight Engineer Sergey Ryazanskiy to the International Space Station. Their Soyuz rocket launched at 4:58 p.m. EDT.
For the third time since crewed space station operations began in 2000, the three crew members will arrive to the orbiting outpost the same day they launched into orbit. Typically, it takes two days for the Soyuz to catch up to and rendezvous with the space station. Hopkins and his crewmates will make that trip in an expedited, four-orbit maneuver.
