Massive Iceberg Floating Away From Pine Island Glacier - This MODIS image taken by NASA’s Aqua satellite on Nov. 10, 2013, shows an iceberg that was part of the Pine Island Glacier and is now separating from the Antarctica continent. What appears to be a connection point on the top left portion of the iceberg is actually ice debris floating in the water. The original rift that formed the iceberg was first observed in October 2011 but as the disconnection was not complete, the “birth” of the iceberg had not yet happened. It is believed the physical separation took place on or about July 10, 2013, however the iceberg persisted in the region, adjacent to the front of the glacier. The iceberg is estimated to be 21 miles by 12 miles (35 km by 20 km) in size, roughly the size of Singapore. A team of scientists from Sheffield and Southampton universities will track it and try to predict its path using satellite data.

Hubble reveals the first visual evidence of how our home galaxy assembled itself into the majestic pinwheel of stars we see today. This composite image shows examples of galaxies similar to our Milky Way at various stages of construction over a time span of 11 billion years. The galaxies are arranged according to time. Those on the left reside nearby; those at far right existed when the cosmos was about 2 billion years old. The bluish glow from young stars dominates the color of the galaxies on the right. The galaxies at left are redder from the glow of older stellar populations. This image traces Milky Way-like galaxies over most of cosmic history, revealing how they evolve over time. Hubble's sharp vision resolved the galaxies' shapes, showing that their bulges and disks grew simultaneously. Credit: NASA, ESA, P. van Dokkum (Yale University), S.

This NASA-generated damage map will assist with Typhoon Haiyan disaster response. When one of the most powerful storms ever recorded on Earth struck the Philippines Nov. 8, 2013, it tore a wide swath of destruction across large parts of the island nation. To assist in the disaster response efforts, scientists at NASA's Jet Propulsion Laboratory, Pasadena, Calif., in collaboration with the Italian Space Agency, generated this image of the storm's hardest-hit regions, depicting its destruction. The 40-by-50 kilometer damage proxy map, which covers a region near Tacloban City, where the massive storm made landfall, was processed by JPL's Advanced Rapid Imaging and Analysis (ARIA) team using X-band interferometric synthetic aperture radar data from the Italian Space Agency's COSMO-SkyMed satellite constellation. The technique uses a prototype algorithm to rapidly detect surface changes caused by natural or human-produced damage. The assessment technique is most sensitive to destruction of the built environment. When the radar images areas with little to no destruction, its image pixels are transparent. Increased opacity of the radar image pixels reflects damage, with areas in red reflecting the heaviest damage to cities and towns in the storm's path. The time span of the data for the change is Aug. 19--Nov. 11, 2013. Each pixel in the damage proxy map is about 30 meters across. Image Credit: ASI/NASA/JPL-Caltech; -
5 Days until the launch of #MAVEN, NASA's next Mars explorer: The Mars Atmosphere and Volatile Evolution, or MAVEN, spacecraft will be the first to study the Red Planet's upper atmosphere. Scientists expect data gathered during the MAVEN mission to help explain how Mars' climate has changed over time due to the loss of atmospheric gases. Pictured here is a road sign adjacent to NASA's Kennedy Space Center in Florida that counts down the days until launch. MAVEN is set to launch aboard a United Launch Alliance Atlas V rocket during a 20-day launch period beginning November 18. The one-year mission begins in Sept. 2014, when the spacecraft reaches Mars orbit.

New View of Saturn! Here’s a natural-color image of Saturn from space, the first in which Saturn, its moons and rings, and Earth, Venus and Mars, all are visible. The new panoramic mosaic of the majestic Saturn system taken by NASA's Cassini spacecraft, which shows the view as it would be seen by human eyes. Cassini's imaging team processed 141 wide-angle images to create the panorama. The image sweeps 404,880 miles (651,591 kilometers) across Saturn and its inner ring system, including all of Saturn's rings out to the E ring, which is Saturn's second outermost ring. For perspective, the distance between Earth and our moon would fit comfortably inside the span of the E ring. Cassini does not attempt many images of Earth because the sun is so close to our planet that an unobstructed view would damage the spacecraft's sensitive detectors. Cassini team members looked for an opportunity when the sun would slip behind Saturn from Cassini's point of view. A good opportunity came on July 19, when Cassini was able to capture a picture of Earth and its moon, and this multi-image, backlit panorama of the Saturn system. Launched in 1997, Cassini has explored the Saturn system for more than nine years. NASA plans to continue the mission through 2017, with the anticipation of many more images of Saturn, its rings and moons, as well as other scientific data.

NASA's MAVEN spacecraft, inside a payload fairing, is hoisted to the top of a United Launch Alliance Atlas V rocket at the Vertical Integration Facility at Cape Canaveral Air Force Station's Space Launch Complex 41. The move and hoisting operations mark another major milestone for the launch team as everything proceeds on schedule to launch Nov. 18, when the Atlas V will lift MAVEN (Mars Atmosphere and Volatile EvolutioN) into space and on to Mars. The two-hour launch window extends from 1:28 to 3:28 p.m. EST. MAVEN is the first spacecraft devoted to exploring and understanding the Martian upper atmosphere. It will orbit the planet in an elliptical orbit that allows it to pass through and sample the entire upper atmosphere on every orbit. The spacecraft will investigate how the loss of Mars' atmosphere to space determined the history of water on the surface.

Typhoon Haiyan seen from the International Space Station: Astronaut Karen Nyberg shared this picture of Typhoon Haiyan early in the morning of Nov. 9, 2013 from the station, some 240 miles above the Earth. Beginning with the Mercury missions in the early 1960s, astronauts have taken photographs of the Earth. Today, the International Space Station (ISS) continues the NASA tradition of Earth observation from human-tended spacecraft. Operational since November 2000, the ISS is well suited for documenting Earth features and provides an excellent stage for observing most populated areas of the world. Images coming down from the International Space Station are processed on a daily basis and include over 1.2 million images through Nov. 1, 2013.

Two Russian cosmonauts made an out-of-this-world handoff of the Olympic torch at the start of Saturday’s spacewalk. Seen here in the capture from NASA TV, Expedition 37 Flight Engineer Oleg Kotov (holding the torch at left) brought the torch out of the International Space Station and passed it to Flight Engineer Sergey Ryazanskiy. The torch was returned to the ISS and the cosmonauts were expected to spend five additional hours conducting maintenance activities. An icon of international cooperation through sports competition, the Olympic torch arrived at the space station Thursday aboard a Soyuz spacecraft carrying three new crew members – Expedition 38 Flight Engineers Mikhail Tyurin, Rick Mastracchio and Koichi Wakata. On Sunday, the torch will return to Earth aboard another Soyuz spacecraft vehicle along with Expedition 37 Commander Fyodor Yurchikhin and Flight Engineers Karen Nyberg and Luca Parmitano. The spacewalk is a high-flying extension of a relay that will culminate with the torch being used to light the Olympic flame at the Feb. 7 opening ceremonies of the 2014 Winter Olympic Games in Sochi, Russia.

It’s a Fireworks Galaxy! This image is of a medium-sized, face-on spiral galaxy that’s about 22 million light years away from Earth. In the past century, eight supernovas have been observed to explode in the arms of this galaxy, called NGC 6946. Chandra observations (purple) have, in fact, revealed three of the oldest supernovas ever detected in X-rays, giving more credence to its nickname of the "Fireworks Galaxy." This composite image also includes optical data from the Gemini Observatory in red, yellow, and cyan.

NASA Satellites see super-Typhoon Haiyan lashing the Philippines in this visible image of the storm taken from the MODIS instrument aboard NASA's Aqua satellite on Nov. 7, 2013, at 11:25 p.m. EST. Super-Typhoon Haiyan is bringing maximum sustained winds of a Category 5 hurricane. NASA is providing visible, infrared and microwave satellite data to forecasters and warnings are in effect for the Philippines and Micronesia as Haiyan moves west. The Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard captured a visible image that showed the thick bands of powerful thunderstorms that surrounded the eye. The MODIS image also revealed a powerful, wide band of thunderstorms in the western quadrant that was affecting the Philippines in the early morning hours (Eastern Daylight Time/U.S.) on Nov. 7. At the same time, another instrument aboard Aqua captured infrared data on the storm using the Atmospheric Infrared Sounder or AIRS instrument, providing cloud top temperatures and sea surface temperatures. The infrared data revealed a sharply defined eye with multiple concentric rings of thunderstorms and a deep convective eyewall. The infrared data showed cloud top temperatures as cold as 210 degrees kelvin/-81.67F/-63.15C/ in the thick band of thunderstorms around the center. Those cold temperatures indicate very high, powerful thunderstorms with very heavy rain potential. The U.S. National Hurricane Center website indicates that a Category 5 hurricane/typhoon would cause catastrophic damage: A high percentage of framed homes will be destroyed, with total roof failure and wall collapse. Fallen trees and power poles will isolate residential areas. Power outages will last for weeks to possibly months. Most of the area will be uninhabitable for weeks or months. After passing through the Philippines, Haiyan is expected to move through the South China Sea as it heads for landfall in Vietnam.
