Astronomers have used NASA's Chandra X-ray Observatory and the European Space Agency's (ESA's) XMM-Newton to show a supermassive black hole six billion light years from Earth is spinning extremely rapidly. This first direct measurement of the spin of such a distant black hole is an important advance for understanding how black holes grow over time.
Earlier this month, NASA's Lunar Atmosphere and Dust Environment Explorer (LADEE) observatory successfully downlinked images of the moon and stars taken by onboard camera systems, known as star trackers. This is the first time the LADEE team commanded the spacecraft to send these pictures back to Earth. read more
Just weeks after NASA's Chandra X-ray Observatory began operations in 1999, the telescope pointed at Centaurus A (Cen A, for short). This galaxy, at a distance of about 12 million light years from Earth, contains a gargantuan jet blasting away...
The London Array is the world's largest offshore wind farm - and it looks even more amazing from space. NASA Earth Observatory just released these beautiful images of the array, which is located off the coast of Kent in England. The images show the vast expanse
The underwater world is a strange and haunting one. This NASA Earth Observatory photograph captures the ethereal beauty of underwater sand dunes in the Bahamas. Tides and ocean currents shape the underwater sand much like wind on land, but the result is just different enough to be otherworldly. More »
Today, NASA’s Earth Observatory brings us this beautiful image of the Missouri River taken from the International Space Station. Its one of its bends occupied by Lake Sharpe, an approximately 130km-long reservoir “formed behind the Big Bend Dam”. More »
Weather-wise, this has been a rather strange and memorable winter. A North American polar vortex and frigid Mars-like temperatures will do that. As this new NASA Earth Observatory map beautifully illustrates, it has been an anomalous winter, indeed. Read more...

A titanic sunspot — about four times the size of Earth — has appeared on January 1, 2014. Called AR1944, it’s the largest sunspot in almost a decade. This image from NASA’s Solar Dynamics Observatory shows it compared to our planet. They are so large you can see them with your naked eye. More »
A NASA observatory that will make the most precise, highest-resolution and most complete, space-based measurements of carbon dioxide in Earth's atmosphere to date has marked a key milestone in preparation for its planned July 2014 launch. read more

The cluster of lights is seen in midst of the Atlantic Ocean. (Credit: NASA Earth Observatory/NOAA National Geophysical Data Center) It sounds like the setup for an episode of "The X-Files." A satellite records evidence of a mysterious cluster of lights in the Atlantic ocean, far from human civilization. Show More Summary
From NASA's Earth Observatory:This photograph taken by an astronaut on the International Space Station highlights a late summer plankton bloom across much of Lake Ontario, one of North America’s Great Lakes. Microscopic cyanobacteria, or blue-green algae, can reach such large concentrations and color the water to such an extent that the change is visible from orbit.
Observations with NASA's Chandra X-ray Observatory have revealed a massive cloud of multimillion-degree gas in a galaxy about 60 million light years from Earth. The hot gas cloud is likely caused by a collision between a dwarf galaxy and a...

Nasa Earth Observatory has a photograph of the recent derailment of a train of Bakken Crude burning and/or exploding in a small town in Quebec. The death total from this event is still unknown. I believe there are about 13 known dead but several are missing and believed to have been incinerated to the point…
These awesome images of the Earth’s Sun were recently captured by NASA’s Solar Dynamics Observatory. They reveal the occurrence of a beautiful solar prominence - an incredibly large and bright loop of red hot plasma created as a solar flare erupted. A burst of solar material leaps off the left side of the sun in what’s known as a prominence eruption. Show More Summary
Three years ago the very first images from the Solar Dynamics Observatory (SDO) were beamed back to earth. Since then, NASA’s SDO has effectively had continuous coverage of the Sun’s rise towards solar maximum, the period of the most intense solar activity in the 11 year solar cycle. Show More Summary
By Adam Voiland, Science Writer at NASA Earth Observatory The Visible Infrared Imaging Radiometer Suite (VIIRS) on the Suomi NPP satellite captured this view of extensive sea-ice fracturing off the northern [...]
Thisamazing image of Arp 147, a pair of interacting galaxies located about 430 million light years from Earth, shows X-rays from the NASA's Chandra X-ray Observatory (pink) and optical data from the Hubble Space Telescope (red, green, blue) produced by...
