An active region of the sun just rotating into the view of NASA's Solar Dynamics Observatory gives a profile view of coronal loops over about a two-day period, from February 8 to 10, 2014. Coronal loops are found around sunspots and in active regions.
Are we on the brink of a robotics revolution? That’s what numerous media outlets asked last...
Migratory birds and military aircraft often fly in a V-shaped formation. The “V” formation...
This photograph of cloud bands over southern Mauritania was taken from the International Space Station with an oblique angle, such that the cloud shadows are a prominent part of the view. Beneath the clouds, the plateau of dark sedimentary rocks appears as a ragged, near-vertical escarpment
This mosaic of images from Curiosity's Mast Camera (Mastcam) shows geological members of the Yellowknife Bay formation. The scene has the Sheepbed mudstone in the foreground and rises up through Gillespie Lake member to the Point Lake outcrop.
On December 6, 1998, the crew of space shuttle mission STS-88 began construction of the International Space Station, attaching the U.S.-built Unity node and the Russian-built Zarya module together in orbit. The crew carried a large-format IMAX camera, used to take this image
The new HITS research group “Astroinformatics” will develop methods and software for astronomers and help facilitating the analysis and processing of the rapidly growing amount of data in astronomy. The junior group led by Kai Polsterer will work closely with other astronomical research groups in Heidelberg.
From the vantage point of the International Space Station, astronauts frequently observe atmospheric and surface phenomena in ways that are impossible to view from the ground. Two such phenomena — gravity waves and sunglint — are illustrated in this photograph of northeastern Lake Superior.
In an age when we're able to consume content so many different ways — and that's a good thing, mostly — let's declare right now that there's only one truly correct way to experience "Gravity," Alfonso Cuaron's thrilling new space film. In a theater. On a huge screen. And in 3-D. Yes, even for all you 3-D naysayers — we hear you, but this is the movie you HAVE to see in 3-D.
A photo captures only as much as the camera in use will allow, and is therefore limited by the field of view of the camera's lens. In the case of smartphones and many advanced cameras, the view from the lens is much smaller than the view from your own eyes.
The splash from rain hitting a windowpane or printer ink hitting paper all comes down to tiny droplets hitting a surface, and what each of those droplets does. Cornell University researchers have produced a high-resolution “photo album” of more than 30 shapes an oscillated drop of water can take. The results, a fundamental insight into how droplets behave, could have applications in everything from inkjet printing to microfluidics.
NASA's Interstellar Boundary Explorer (IBEX) spacecraft recently provided the first complete pictures of the solar system's downwind region, revealing a unique and unexpected structure. Researchers have long theorized that, like a comet, a "tail" trails the heliosphere, the giant bubble in which our solar system resides
Scientists using images from NASA's Mars Reconnaissance Orbiter, or MRO, have estimated that the planet is bombarded by more than 200 small asteroids or bits of comets per year forming craters at least 12.8 feet (3.9 meters) across. Researchers have identified 248 new impact sites on parts of the Martian surface in the past decade
A standard camera takes flat, 2-D pictures. To get 3-D information, such as the distance to a far-away object, scientists can bounce a laser beam off the object and measure how long it takes the light to travel back to a detector. The technique, called time-of-flight (ToF), is already used in machine vision, navigation systems for autonomous vehicles, and other applications, but many current ToF...
The Whirlpool Galaxy is a classic spiral galaxy. At only 30 million light years distant and fully 60 thousand light years across, M51, also known as NGC 5194, is one of the brightest and most picturesque galaxies on the sky. This image is a digital combination of a ground-based image from the 0.9-meter telescope at Kitt Peak National Observatory and a space-based image from the Hubble Space Telescope.
The Hubble Space Telescope captured a spectacular image of the bright star-forming ring that surrounds the heart of the barred spiral galaxy NGC 1097. In this image, the larger-scale structure of the galaxy is barely visible: its comparatively dim spiral arms, which surround its heart in a loose embrace, reach out beyond the edges of this frame
This rectangular version of a self-portrait of NASA's Mars rover Curiosity combines dozens of exposures taken by the rover's Mars Hand Lens Imager (MAHLI) during the 177th Martian day, or sol, of Curiosity's work on Mars
This new view of the historical supernova remnant Cassiopeia A, located 11,000 light-years away, was taken by NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR
NASA’s Kepler mission has identified 2,740 planets orbiting other stars, but do any of them harbor intelligent life? Scientists have used the Green Bank Telescope to look for intelligent radio signals from planets around 86 of these stars
Technicians prepare to fit a special fixture around an Orion capsule inside the high bay of the Operations & Checkout Building at NASA's Kennedy Space Center in Florida. The fixture is designed to enable precise pre-launch processing of the Orion spacecraft
Whether you’re planning an upcoming hike, or want to learn more about the Earth’s geological history, Google Maps can help. We’re releasing panoramic imagery of one of the world’s most spectacular national monuments: the Grand Canyon. These beautiful, interactive images cover more than 75 miles of trails and surrounding roads, making our map of this area even more comprehensive, accurate and easy to use than ever before.
This new view of spiral galaxy IC 342, also known as Caldwell 5, includes data from NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR
Astronauts on board the International Space Station captured this view of Washington, D.C. and the surrounding area on January 20, 2013, one day before the public Inauguration of President Barack Obama
NASA has joined the European Space Agency's (ESA's) Euclid mission, a space telescope designed to investigate the cosmological mysteries of dark matter and dark energy. Euclid will launch in 2020 and spend six years mapping the locations and measuring the shapes of as many as two billion galaxies
After more than a month of eruption, lava continues to flow from Tolbachik, one of many active volcanoes on Russia’s Kamchatka Peninsula
A solar eruption gracefully rose up from the sun on December 31, 2012, twisting and turning. Magnetic forces drove the flow of plasma, but without sufficient force to overcome the sun’s gravity
On January 4, 2013, a large presence of stratocumulus clouds was the central focus of camera lenses, which remained aimed at the clouds as the Expedition 34 crew members aboard the International Space Station flew above the northwestern Pacific Ocean
