Fires have raged throughout Alaska in 2015. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite acquired this image on July 14, 2015. Actively burning areas, detected by the thermal bands on MODIS, are outlined in red. According to the most recent update (July 16, 2015) from the Alaska Interagency Coordination Center, about 304 fires were actively burning when MODIS imaged the area. To date, fires have charred a total of 4,854,924 acres in Alaska. The worst fire season in Alaska's history was in 2004. At this point in time, 2015 is a month ahead of the totals in 2004 putting it on track surpass the fire totals in 2004. The amount of acreage burned in Alaska during June 2015 shattered the previous acreage record set in June 2004 by more than 700,000 acres delivering a sobering piece of news for Alaskan residents.

2015 was the warmest year since modern record-keeping began in 1880, according to a new analysis by NASA’s Goddard Institute for Space Studies. The record-breaking year continues a long-term warming trend — 15 of the 16 warmest years on record have now occurred since 2001. Credits: Scientific Visualization Studio/Goddard Space Flight Center Details: Earth’s 2015 surface temperatures were the warmest since modern record keeping began in 1880, according to independent analyses by NASA and the National Oceanic and Atmospheric Administration (NOAA). Globally-averaged temperatures in 2015 shattered the previous mark set in 2014 by 0.23 degrees Fahrenheit (0.13 Celsius). Only once before, in 1998, has the new record been greater than the old record by this much. The 2015 temperatures continue a long-term warming trend, according to analyses by scientists at NASA’s Goddard Institute for Space Studies (GISS) in New York (GISTEMP). NOAA scientists agreed with the finding that 2015 was the warmest year on record based on separate, independent analyses of the data. Because weather station locations and measurements change over time, there is some uncertainty in the individual values in the GISTEMP index. Taking this into account, NASA analysis estimates 2015 was the warmest year with 94 percent certainty.

This visualization shows the Moon's phase and libration at hourly intervals throughout 2015, as viewed from the northern hemisphere. Each frame represents one hour. Lunar Reconnaissance Orbiter (LRO) has been in orbit around the Moon since the summer of 2009. Its laser altimeter (LOLA) and camera (LROC) are recording the rugged, airless lunar terrain in exceptional detail, making it possible to visualize the Moon with unprecedented fidelity. This is especially evident in the long shadows cast near the terminator, or day-night line. The pummeled, craggy landscape thrown into high relief at the terminator would be impossible to recreate in the computer without global terrain maps like those from LRO.

Very hot, dry and unstable conditions in California and across the Pacific Northwest add to the challenges facing firefighters as they battle blazes around the region. Cal Fire is urging Californians to be extremely cautious, especially for the next few days, as the current conditions increase the dangers authorities face. This image was taken by NASA-NOAA's Suomi NPP satellite's VIIRS instrument around 2145 UTC (5:45 p.m. EDT) on August 17, 2015. Northern California is seeing smoke from the River Complex, Route Complex, South Complex, Fork Complex and Mad River Complex fires combine over a large area of the Shasta-Trinity National Forest west of Redding, California, while the Rough Fire in Fresno County is spreading toward the Black Rock Reservoir, causing evacuations and road closures. Fires across the Pacific Northwest aren't limited to California. Please see the Suomi NPP VIIRS composites in NOAA View to see the growth and extent of fires over the past weeks.

As the sun sets over the Arctic, the end of this year’s melt season is quickly approaching and the sea ice cover has already shrunk to the fourth lowest in the satellite record. With possibly some days of melting left, the sea ice extent could still drop to the second or third lowest on record. Arctic sea ice, which regulates the planet’s temperature by bouncing solar energy back to space, has been on a steep decline for the last two decades. This animation shows the evolution of Arctic sea ice in 2015, from its annual maximum wintertime extent, reached on February 25, to September 6.

CAPE CANAVERAL, Fla. -- NASA Administrator Charlie Bolden, standing near Orion, looked over the agency's spacecraft this morning for the first time since it returned to Kennedy Space Center following the successful Orion flight test on Dec. 5. Bearing the marks of a spacecraft that has returned to Earth through a searing plunge into the atmosphere, Orion is perched on a pedestal inside the Launch Abort System Facility at Kennedy where it is going through post-mission processing. Although the spacecraft Bolden looked over did not fly with a crew aboard during the flight test, Orion is designed to carry astronauts into deep space in the future setting NASA and the nation firmly on the journey to Mars.

The sun emitted a mid-level solar flare, peaking at 11:24 p.m. EST on Jan. 12, 2015. NASA’s Solar Dynamics Observatory, which watches the sun constantly, captured an image of the event. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however -- when intense enough -- they can disturb the atmosphere in the layer where GPS and communications signals travel. This flare is classified as an M5.6-class flare. M-class flares are a tenth the size of the most intense flares, the X-class flares. The number provides more information about its strength. An M2 is twice as intense as an M1, an M3 is three times as intense, etc. Credit: NASA/Goddard/SDO <b><a href="http://www.nasa.gov/audience/formedia/features/MP_Photo_Guidelines.html" rel="nofollow">NASA image use policy.</a></b> <b><a href="http://www.nasa.gov/centers/goddard/home/index.html" rel="nofollow">NASA Goddard Space Flight Center</a></b> enables NASA’s mission through four scientific endeavors: Earth Science, Heliophysics, Solar System Exploration, and Astrophysics.

JSC FLIGHT DIRECTOR CLASS OF 2015 VISITS THE INTERNATIONAL SPACE STATION PAYLOAD OPERATION INTEGRATION CENTER AT MSFC, NOVEMBER 17, 2015

The sun emitted a significant solar flare, peaking at 12:22 p.m. EDT on March 11, 2015. NASA’s Solar Dynamics Observatory, which watches the sun constantly, captured an image of the event. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however -- when intense enough -- they can disturb the atmosphere in the layer where GPS and communications signals travel. This flare is classified as an X2.2-class flare. X-class denotes the most intense flares, while the number provides more information about its strength. An X2 is twice as intense as an X1, an X3 is three times as intense, etc. This image was captured by NASA's Solar Dynamics Observatory and shows a blend of light from the 171 and 131 Ångström wavelengths.

CAPE CANAVERAL, Fla. - At NASA's Kennedy Space Center in Florida, STS-131 Mission Specialist Clayton Anderson takes his instructor, Battalion Chief David Seymour, for a ride in an M-113 armored personnel carrier during driving practice. An M-113 is kept at the foot of the launch pad in case an emergency egress from the vicinity of the pad is needed. The crew members of space shuttle Discovery's STS-131 mission are at Kennedy for training related to their launch dress rehearsal, the Terminal Countdown Demonstration Test. The seven-member crew will deliver the multi-purpose logistics module Leonardo, filled with resupply stowage platforms and racks, to the International Space Station aboard Discovery. Targeted for launch on April 5, STS-131 will be the 33rd shuttle mission to the station and the 131st shuttle mission overall.

Images from Dawn's visible and infrared mapping spectrometer (VIR) show a portion of Ceres' cratered northern hemisphere, taken on May 16, 2015. From top to bottom, the views include a black-and-white image, a true-color view and a temperature image. The true-color view contains reddish dots that are image artifacts, which are not part of Ceres' surface. These images were taken at a distance of 4,500 miles (7,300 kilometers) from Ceres. They have a resolution of 1.1 miles (1.8 kilometers) per pixel. The temperature image is derived from data in the infrared light range. The lightest areas are the hottest and the darkest are the coolest. http://photojournal.jpl.nasa.gov/catalog/PIA19571
