At night, we see the stars…but what do the stars see? Take a look at this stunning image of Earth at night! Providing the clearest yet composite view of the patterns of human settlement across our planet, this is the first new global map of Earth at night since 2012. More: http://go.nasa.gov/2pvGG1X

Did you know that the International Space Station is the third brightest object in the night sky? It’s easy to spot too! Find out when and where to look up: https://spotthestation.nasa.gov/

How do we move rocket parts that'll carry humans farther into space than ever before? The barge Pegasus, seen here, will carry a test article engine section of our Space Launch System rocket that will be tested at our Marshall Space Flight Center in Alabama. While there, hydraulic cylinders will be electronically controlled to push, pull, twist and bend the test article with millions of pounds of force to ensure the hardware can withstand the extreme forces of launch and ascent.

Gamma-ray bursts on Earth? About a thousand times a day, thunderstorms fire off fleeting bursts of some of the highest-energy light naturally found on Earth. These events, called terrestrial gamma-ray flashes last less than a millisecond and produce gamma rays with tens of millions of times the energy of visible light.

This Week @NASA: "534 days and counting ..." President Trump and astronaut Kate Rubins congratulated Peggy Whitson for breaking the record for time spent in space by a U.S. astronaut. Our Cassini spacecraft began its final mission--the Grand Finale. The Space Station crew discussed scientific research and filmmaking at the first 4K downlink from space with the National Association of Broadcasters and more! Watch: http://go.nasa.gov/2pufelt

Dark matter, the mysterious, invisible substance that makes up a majority of matter in the universe…is it fuzzy? A new study using data from our Chandra X-ray Observatory explores this possibility. Get the details: http://go.nasa.gov/2puevAp

This galaxy--with its bright bursts of star formation--blends into the background somewhat thanks to the gloriously bright star hogging the limelight next to it. Details: https://www.nasa.gov/image-feature/goddard/2017/hubbles-bright-shining-lizard-star

The magnetic field lines between a pair of active regions formed a beautiful set of swaying arches, seen in this footage captured by our Solar Dynamics Observatory on April 24-26, 2017. These arches, which form a connection between regions of opposite magnetic polarity, are visible in exquisite detail in this wavelength of extreme ultraviolet light. Extreme ultraviolet light is typically invisible to our eyes, but is colorized here in gold. Take a look: https://go.nasa.gov/2pGgYZt
