The latest image of sea surface heights in the Pacific Ocean from NASA's Jason-2 satellite shows that the equatorial Pacific Ocean is now in its 16th month of being locked in what some call a neutral, or "La Nada" state. "La Nadas" make long-range climate forecasting more difficult due to their greater unpredictability. Yellows and reds indicate areas where waters are relatively warmer and have expanded above normal sea level, while blues and purple areas show where waters are relatively colder and sea level is lower than normal. The near-normal conditions are shown as areas shaded in green, based on the average of 10 days of data centered on Aug. 27, 2013. The height of the sea water relates, in part, to its temperature, and thus is an indicator of the amount of heat stored in the ocean below. As the ocean warms, its level rises; as it cools, its level falls. Above-normal height variations along the equatorial Pacific indicate El Niño conditions, while below-normal height variations indicate La Niña conditions. The temperature of the upper ocean can have a significant influence on weather patterns and climate. For the past several decades, about half of all years have experienced La Nada conditions, compared to about 20 percent for El Niño and 30 percent for La Niña. NASA scientists will continue to monitor this persistent La Nada event to see what the Pacific Ocean has in store next for the world's climate.

The extreme floods that have been threatening northeastern China and the Russian Far East are slowly moving north along the length of the Amur River. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite acquired the left false-color image of the swollen Amur River on September 8, 2013. The right image, also from Aqua MODIS, shows the river on August 17, 2012, providing a view of normal water levels during the late summer. The false-color images were made with short-wave and near-infrared light. Water is black; plant-covered land is green; clouds are pale blue and white; and burned land is red. The city of Komsomolsk-on-Amur is pale brown. The winding river channels and sponge-like appearance of the land around the river in the 2012 image indicates the presence of wetlands.

Hubble Catches a Spiral in the Air Pump Lying more than 110 million light-years away from Earth in the constellation of Antlia (The Air Pump) is the spiral galaxy IC 2560, shown here in an image from NASA/ESA Hubble Space Telescope. At this distance it is a relatively nearby spiral galaxy, and is part of the Antlia cluster — a group of over 200 galaxies held together by gravity. This cluster is unusual; unlike most other galaxy clusters, it appears to have no dominant galaxy within it. In this image, it is easy to spot IC 2560's spiral arms and barred structure. This spiral is what astronomers call a Seyfert-2 galaxy, a kind of spiral galaxy characterized by an extremely bright nucleus and very strong emission lines from certain elements — hydrogen, helium, nitrogen, and oxygen. The bright center of the galaxy is thought to be caused by the ejection of huge amounts of super-hot gas from the region around a central black hole. There is a story behind the naming of this quirky constellation — Antlia was originally named antlia pneumatica by French astronomer Abbé Nicolas Louis de Lacaille, in honor of the invention of the air pump in the 17th century.

NASA's black-hole-hunter spacecraft, the Nuclear Spectroscopic Telescope Array, or NuSTAR, has "bagged" its first 10 supermassive black holes. The mission, which has a mast the length of a school bus, is the first telescope capable of focusing the highest-energy X-ray light into detailed pictures. The new black-hole finds are the first of hundreds expected from the mission over the next two years. These gargantuan structures -- black holes surrounded by thick disks of gas -- lie at the hearts of distant galaxies between 0.3 and 11.4 billion light-years from Earth. This image shows the optical color of galaxies seen here overlaid with X-ray data (magenta) from NASA's NuSTAR. Image Credit: NASA/JPL-Caltech; -
The image shows Earth today, September 7, 2013, as seen by the Geostationary Operational Environmental Satellites (GOES) satellite. Geostationary describes an orbit in which a satellite is always in the same position with respect to the rotating Earth. This allows GOES to hover continuously over one position on the Earth's surface, appearing stationary. As a result, GOES provide a constant vigil for the atmospheric "triggers" for severe weather conditions such as tornadoes, flash floods, hail storms, and hurricanes.

The Lunar Atmosphere and Dust Environment Explorer (LADEE) is headed toward the moon after launching on a #Minataur V rocket Friday night from NASA's Wallops Flight Facility in Virginia. LADEE is a robotic mission that will orbit the moon to gather detailed information about the lunar atmosphere, conditions near the surface and environmental influences on lunar dust. A thorough understanding of these characteristics will address long-standing unknowns, and help scientists understand other planetary bodies as well.

Evening View of LADEE's Gantry! This image shows an evening view gantry at Pad 0B at the Mid-Atlantic Regional Spaceport, at NASA's Wallops Flight Facility in Wallops Island, Va., on Sept. 4, 2013. In this photograph, the gantry surrounds the Minotaur V rocket that will launch NASA LADEE. The gantry is now removed and the Minotaur is getting ready to launch LADEE at 11:27 p.m. EDT tonight.

LADEE Ready for Launch! NASA is making final preparations to launch a moon probe tonight at 11:27 p.m. EDT from NASA's Wallops Flight Facility in Virginia. Watch it live at: http://www.nasa.gov/ntv The small car-sized LADEE is a robotic mission that will orbit the moon to gather detailed information about the structure and composition of the thin lunar atmosphere and determine whether dust is being lofted into the lunar sky. A thorough understanding of these characteristics of our nearest celestial neighbor will help researchers understand other bodies in the solar system, such as large asteroids, Mercury, and the moons of outer planets.

Water on the moon! More lunar images to get you excited for tonight’s LADEE probe launch. LADEE is scheduled to lift off at 11:27 p.m. EDT on a mission to study the atmosphere of our cosmic neighbor. NASA-funded lunar research has yielded evidence of water locked in mineral grains on the surface of the moon from an unknown source deep beneath the surface. The findings were published Aug. 25 in Nature Geoscience. Using data from NASA’s Moon Mineralogy Mapper (M3) instrument aboard the Indian Space Research Organization’s Chandrayaan-1 spacecraft, scientists remotely detected magmatic water, or water that originates from deep within the moon’s interior, on the surface of the moon. Pictured is the central peak of Bullialdus, which has significantly more hydroxyl — a molecule consisting of one oxygen atom and one hydrogen atom, rising above the crater floor with the crater wall in the background.

The moon from the space station! More Instagram Moon Day posts in honor of tonight’s LADEE lunar probe launch at 11:27 p.m. EDT. You can watch it live on NASA TV: http://www.nasa.gov/ntv Photographed by the Expedition 28 crew aboard the International Space Station, this image shows the moon at center with the limb of Earth near the bottom transitioning into the orange-colored troposphere, the lowest and most dense portion of the Earth's atmosphere. The troposphere ends abruptly at the tropopause, which appears in the image as the sharp boundary between the orange- and blue-colored atmosphere. The silvery-blue noctilucent clouds extend far above the Earth's troposphere. Image credit: NASA #nasa #moon #space #ladee #iss;

Earth from the Moon! To celebrate tonight’s scheduled 11:27 p.m. EDT launch of our Lunar Atmosphere and Dust Environment Explorer (LADEE) spacecraft, it’s moon day on NASA's new Instagram, where we bring you photos from our planet and beyond. This image taken July 20, 1969 from Apollo 11 shows the Earth rising over the limb of the moon much as the Harvest Moon does from our planetary perspective. Over the stark, scarred surface of the moon, the Earth floats in the void of space, a watery jewel swathed in ribbons of clouds.
