Warm Gas Pours 'Cold Water' on Galaxy's Star-Making: A new feature in the evolution of galaxies has been captured in this image of galactic interactions. The two galaxies seen here -- NGC 3226 at the top, NGC 3227 at the bottom -- are awash in the remains of a departed third galaxy, cannibalized by the gravity of the surviving galaxies. The surge of warm gas flowing into NGC 3226, seen as a blue filament, appears to be shutting down this galaxy's star formation, disrupting the cool gas needed to make fresh stars. The findings come courtesy of the European Space Agency's Herschel space observatory, in which NASA played a key role, and NASA's Spitzer and Hubble space telescopes. Adding material to galaxies often rejuvenates them, triggering new rounds of star birth as gas and dust gel together. Yet data from the three telescopes all indicate that NGC 3226 has a very low rate of star formation.

Historic Blue Marble Image: On this day in 1972, Apollo 17 launched to the moon, and the crew snapped this photo of Earth on the way. The original caption is reprinted below: View of the Earth as seen by the Apollo 17 crew traveling toward the moon. This translunar coast photograph extends from the Mediterranean Sea area to the Antarctica south polar ice cap. This is the first time the Apollo trajectory made it possible to photograph the south polar ice cap. Note the heavy cloud cover in the Southern Hemisphere. Almost the entire coastline of Africa is clearly visible. The Arabian Peninsula can be seen at the northeastern edge of Africa. The large island off the coast of Africa is the Malagasy Republic. The Asian mainland is on the horizon toward the northeast. Image Credit: NASA #nasa #apollo #otd #bluemarble #bluedot #earth #history; -
Seeking Planets in the Dust: A dusty planetary system (left) is compared to another system with little dust in this artist's conception. Dust can make it difficult for telescopes to image planets because light from the dust can outshine that of the planets. Dust reflects visible light and shines with its own infrared, or thermal, glow. As the illustration shows, planets appear more readily in the planetary system shown at right with less dust. Research with the NASA-funded Keck Interferometer, a former NASA key science project that combined the power of the twin telescopes of the W.M. Keck Observatory atop Mauna Kea, Hawaii, shows that mature, sun-like stars appear to be, on average, not all that dusty. This is good news for future space missions wanting to take detailed pictures of planets like Earth and seek out possible signs of life.

Less than 24 hours before the launch of NASA’s Orion spacecraft atop a United Launch Alliance (ULA) Delta IV Heavy rocket, the L-1 forecast has improved to and there is a 70 percent chance of favorable weather. The two concerns remain the Flight Through Precipitation and Liftoff Wind Rules. The forecast prepared by the Spaceflight Meteorology Group at NASA’s Johnson Space Center in Houston continues to be favorable for Orion’s Pacific Ocean splashdown about 4.5 hours after launch. The detailed weather forecast is below. Orion’s flight test is the next step in NASA’s journey to Mars. Orion is NASA’s new spacecraft built to carry astronauts to destinations never before visited by humans, including an asteroid and Mars. On this uncrewed test flight, Orion will test systems critical to crew safety, including the heat shield, parachutes, avionics and attitude control, as it travels farther into space than any spacecraft built for humans has traveled in more than 40 years. Liftoff is scheduled for 7:05 a.m. EST on Thursday from Space Launch Complex 37 at Cape Canaveral Air Force Station, Florida. During its two-orbit flight, Orion will travel 3,600 miles in altitude and travel nearly 60,000 miles before returning to Earth. Orion will return through Earth’s atmosphere at speeds approaching 20,000 mph, generating temperatures near 4,000 degrees Fahrenheit on its heat shield. The spacecraft will land approximately 600 miles off the coast of Baja, California. Orion will be recovered by a combined NASA and U.S. Navy team that will attach it to cables that will pull it into the flooded well deck of the USS Anchorage.

The Orion spacecraft will take crews farther from Earth than any human-rated spacecraft since Apollo. The first step of that adventure comes this week when the Orion flight test sends an uncrewed version of the capsule about 3,600 miles above Earth – far enough to encounter the high radiation zones that circle the planet and measure their effects on the inside of the spacecraft. On its way back home, Orion’s heat shield will bear the brunt of scorching plasma as the spacecraft dives into the atmosphere at 20,000 mph before slowing for splashdown. It’s a stress test for more than the spacecraft, of course – people from NASA and Lockheed Martin along with scores of others involved in the program will watch every readout carefully. No matter what happens, the flight test has already made strides in development of America’s next deep-space vehicle for astronauts. Live coverage begins on NASA's website and on NASA TV at 4:30 a.m. EST on Thursday, Dec. 4. A 2-hour, 39-minute launch window opens at 7:05 a.m. EST so the launch and recovery of the spacecraft after splashdown can both take place in daylight. Orion will lift off on the strength of a United Launch Alliance Delta IV Heavy, currently the largest rocket in America's inventory. Pictured here is an artists rendering of the Orion spacecraft.

Orion Spacecraft at the Launch Pad: With access doors at Space Launch Complex 37 opened on Nov. 24, 2014, the Orion spacecraft and Delta IV Heavy stack is visible in its entirety inside the Mobile Service Tower where the vehicle is undergoing launch preparations. Orion will make its first flight test on Dec. 4 with a morning launch atop the United Launch Alliance Delta IV Heavy rocket. Orion’s crew module is underneath the Launch Abort System and nose fairing, both of which will jettison about six minutes, 20 seconds after launch. The tower will be rolled away from the rocket and spacecraft 8 hours, 15 minutes before launch to allow the rocket to be fueled and for other launch operations to proceed. The spacecraft will orbit the Earth twice, including one loop that will reach 3,600 miles above Earth. No one will be aboard Orion for this flight test, but the spacecraft is being designed and built to carry astronauts on exploration missions into deep space. Launch is scheduled for Thursday, Dec. 4 at 7:05 a.m. EST, the opening of a 2 hour, 39-minute window for the day. The L-3 Day launch weather forecast 60 percent "go."

It's #BlackFriday, but for us, it's the 2nd annual #BlackHoleFriday. Thank you for joining us as we shared images & information about black holes. We'll keep hunting for black holes and studying them. How? Spotting black holes is tricky. Because they don’t give off light, astronomers have a difficult time pinpointing their location. But when a black hole gets close enough to an object, like a star, for example, and begins consuming the object's mass, the matter that pours into its gravitational clutches can get so hot that it glows and releases energy in the form of X-ray light. The most powerful X-rays are emitted from the hottest material swirling just outside the edge of the black hole. By observing this light with space telescopes, scientists can determine where black holes are hiding in the cosmos. Credit: NASA's Goddard Space Flight Center; -
It's #BlackFriday, but for us, it's the 2nd annual #BlackHoleFriday. Today, we'll post pics & info about black holes. Astronomers using data from NASA’s Hubble Space Telescope and ground observation have found an unlikely object in an improbable place -- a monster black hole lurking inside one of the tiniest galaxies ever known. The black hole is five times the mass of the one at the center of our Milky Way galaxy. It is inside one of the densest galaxies known to date -- the M60-UCD1 dwarf galaxy that crams 140 million stars within a diameter of about 300 light-years, which is only 1/500th of our galaxy’s diameter. If you lived inside this dwarf galaxy, the night sky would dazzle with at least 1 million stars visible to the naked eye. Our nighttime sky as seen from Earth’s surface shows 4,000 stars. The finding implies there are many other compact galaxies in the universe that contain supermassive black holes. The observation also suggests dwarf galaxies may actually be the stripped remnants of larger galaxies that were torn apart during collisions with other galaxies rather than small islands of stars born in isolation. Seen here is an artist's view of M60-UCD1 black hole. Image Credit: NASA, ESA, STScI-PRC14-41a;
