City lights in the U.S. increased in brightness by up to 50 percent during the holiday season. Image by NASA's Earth Observatory/Jesse Allen. For the first time, researchers are able to observe changes in light intensity and light output over time from images taken from space. Show More Summary
The NASA Solar Dynamics Observatory has released this beautiful video of a large coronal hole, which was a large feature on the Sun the week of November 30, 2014. Coronal hole are areas where the Sun’s magnetic field is open ended and where high–speed solar wind streams particles into space. The area appears darker there […]
In an effort to show us our impact on the planet, NASA's Earth Observatory has a series of time-lapsed images from around the world. Each one shows the significant impact of humans have on the environment around them. The Aral Sea is practically gone. Show More Summary
Briefly: NASA’s Astronomy Picture of the Day is this view of the October 8 lunar eclipse taken by Yuri Beletsky at Las Campanas Observatory, Chile. The shadow of the Earth cutting through, the glow, the misty sea that fades into the sky itself — so otherworldly and ethereal. More »
Both terrestrial telescopes and their orbital counterparts have some pretty significant limitations—ground based observatories must deal with the obscuring effects of the Earth's atmosphere and space telescopes are incredibly expensive to launch. But NASA's newest telescope will deliver space-quality observations at a Earth-bound 'scope price. Read more...
As George Clooney's character in Gravity said, "You can't beat the view" NASA Expedition 38 crew members Mike Hopkins and Rick Mastracchio recorded this incredible footage of Earth from the Cupola - the massive observatory module of the ISS. As...
NASA's Solar Dynamics Observatory captured video of a solar storm, and radiation could be headed towards Earth
From NASA Goddard – NASA’s STEREO “Winks” and Provides Stunning Solar Imagery NASA’s Solar Terrestrial Relations Observatory witnessed a dramatic solar eruption on Aug. 24, 2014 — even with one of its “eyes” partially closed. Video: A bright eruption of solar material surges into space as captured by NASA’s Solar Terrestrial Relations Observatory – Before…
NASA's newest satellite has arrived in its final orbit and begun tracking levels of the heat-trapping gas carbon dioxide in Earth's atmosphere. The Orbiting Carbon Observatory 2 (OCO-2), which blasted off July 2, arrived in its final orbit 438 miles (705 kilometers) above the Earth on Aug. Show More Summary
With the launch of the Orbiting Carbon Observatory (or or OCO-2), NASA has taken the first step towards the kind of ‘Treknology’ we are used to seeing in our favorite fictional future. TrekMovie was at the launch as part of a NASA Social event, plus we were lucky enough to catch an inspiring speech from […]
Right now, io9's Mika McKinnon is at the launch for the Orbiting Carbon Observatory, a satellite which will track where the Earth draws carbon out of the atmosphere. It could give us hints about why the climate is changing — and how we can intervene more quickly. Here's how the OCO works. Read more...
NASA's Chandra X-ray observatory has found a mysterious X-ray signal that astronomers are speculating could signal the presence of dark matter some 240 million light years away from Earth. A leading theory, NASA reports, is that the X-rays are a result of decaying "sterile neutrinos," which are particles that could potentially produce dark matter. Show More Summary
NASA's first spacecraft dedicated to measuring carbon dioxide levels in Earth's atmosphere is in final preparations for a July 1 launch from Vandenberg Air Force Base, California. The Orbiting Carbon Observatory-2 (OCO-2) mission will...Show More Summary
NASA has successfully completed the first test of the International Space Station's new OPALS laser communications system. OPALS links the ISS to an observatory here on Earth at very high speeds (around 50 megabits per second), allowing for the real-time transmission of high-resolution video among other things.

From NASA JPL and Lamont-Doherty Earth Observatory, something that maybe journo-hacktivist Susanne Goldenberg should pay attention to before she writes another screed. Reports that a portion of the West Antarctic Ice Sheet has begun to irretrievably collapse, threatening a 4-foot … Continue reading ?
NASA's Earth Observatory posted these two comparison images of sea surface patterns in May of 1997, before that year's infamously terrible El Niño, and this month. The images are startlingly similar, suggesting we might be on the precipice of another tough El Niño year. Read more...
The reason for the Earth’s seasons is succinctly explained using space imagery in this 2011 video from NASA Earth Observatory. As the year goes on, and the Sun’s rays hit the Earth differently based on the planet’s relative position to the sun, the seasons change. Winter in a hemisphere is essentially a lack of sunlight. [...]
In this post, NASA's Earth Observatory drops some facts on the cause, detection, and number of lightning bolts in our active atmosphere:Across the atmosphere of Earth, lightning flashes about 50 times per second. That’s 4.3 million times a day and roughly 1.5 billion times a year. Show More Summary
