The 2015 wildfire season in the Arctic has been very intense – and very smoky. As of July 15, over 3,190,000 acres had burned across Canada, according to Natural Resources Canada. According to the National Oceanic and Atmospheric Administration (NOAA), more than 600 fires had burned millions of acres in Alaska as of July 7.
Pluto’s icy mountains have company. NASA’s New Horizons mission has discovered a new, apparently less lofty mountain range on the lower-left edge of Pluto’s best known feature.
A NASA camera on the Deep Space Climate Observatory satellite has returned its first view of the entire sunlit side of Earth from one million miles away.
Peering closely at the “heart of Pluto,” in the western half of what mission scientists have informally named Tombaugh Regio (Tombaugh Region), New Horizons’ Ralph instrument revealed evidence of carbon monoxide ice. The contours indicate that the concentration of frozen carbon monoxide increases towards the center of the “bull’s eye.”
This image of the sun was taken on July 15, 2015, with the Extreme Ultraviolet Imager onboard NASA's Solar TErrestrial RElations Observatory Ahead (STEREO-A) spacecraft, which collects images in several wavelengths of light that are invisible to the human eye. This image shows the sun in wavelengths of 171 angstroms, typically colorized in blue.
New close-up images of a region near Pluto’s equator reveal a giant surprise: a range of youthful mountains.
Guests and New Horizons team members countdown to the spacecraft's closest approach to Pluto, Tuesday, July 14, 2015.
One million miles to go; Pluto is more intriguing than ever!
This little-known galaxy, officially named J04542829-6625280, but most often referred to as LEDA 89996, is a classic example of a spiral galaxy.
On Jan. 19, 2006, Clouds part as NASA’s New Horizons spacecraft roars into the blue sky after an on-time liftoff at 2 p.m. EST aboard an Atlas V rocket from Complex 41 on Cape Canaveral Air Force Station in Florida.
Flaring, active regions of our sun are highlighted in this new image combining observations from several telescopes.
On July 7, 2003, NASA launched its second Mars Exploration Rover, Opportunity, aboard a Delta II launch vehicle. Opportunity and its twin rover Spirit landed on Mars in 2004 to begin missions planned to last three months. Both rovers far exceeded those plans. Spirit worked for six years, and Opportunity is still active.
Despite its cold waters and harsh winds, the North Sea is a fertile basin for phytoplankton blooms. The drifting, plantlike organisms tend to be most abundant in late spring and early summer due to high levels of nutrients in the water and increasing sunlight.
While fireworks only last a short time here on Earth, a bundle of cosmic sparklers in a nearby cluster of stars will be going off for a very long time.
This view of the American flag medallion on NASA's Mars rover Curiosity was taken by the rover's Mars Hand Lens Imager (MAHLI) during the 44th Martian day, or sol, of Curiosity's work on Mars (Sept. 19, 2012). The flag is one of four "mobility logos" placed on the rover's mobility rocker arms.
The High Resolution Imaging Science Experiment (HiRISE) camera aboard NASA's Mars Reconnaissance Orbiter acquired this closeup image of a light-toned deposit in Aureum Chaos, a 368 kilometer (229 mile) wide area in the eastern part of Valles Marineris, on Jan. 15, 2015, at 2:51 p.m. local Mars time.
In late May 2015, the highest volcano in the Galapagos Islands, Wolf volcano, erupted for the first time in 33 years. The wide image and closeup of Wolf was acquired on June 11, 2015, by the ASTER instrument on NASA's Terra satellite. The false-color images combine near-infrared, red, and green light (ASTER bands 3-2-1).
Although the D ring of Saturn is so thin that it's barely noticeable compared to the rest of the ring system, it still displays structures seen in other Saturnian rings.
Astronaut Ron Garan tweeted this image from the International Space Station in August, 2011, writing, “What a `Shooting Star’ looks like from space, taken yesterday during Perseid Meteor Shower.” A special camera to record meteor showers will launch to the station aboard SpaceX's Dragon cargo craft, currently scheduled to launch on June 28, 2015.
