Solar Photographer Spots Mercury On Its Trip Across the Sun

On May 9, 2016, over the course of seven and a half hours beginning at 7:12 a.m. EDT (11:12 UTC) Mercury passed across the disk of the Sun, appearing to observers on Earth as a small dark dot in front of the massive brilliance of our home star. While the event wasn’t visible to the naked…

Pluto Looks Amazing (Again) in the Latest View From New Horizons

At the beginning of September the world was treated to a fantastic view of the night side of Pluto, captured by the New Horizons spacecraft as it departed the distant icy world on July 14, 2015. Backlit by the sun, Pluto’s surprisingly complex atmospheric haze created a ghostly glow above its crescent-lit limb while frozen mountains cast…

Supermoon Eclipse 2015

Last night a large part of the world’s population was treated to a relatively rare variety of a not-so-rare night sky spectacle: a total lunar eclipse that happened to coincide with the closest perigee Moon (aka “supermoon”) of the year. The last time these scenarios lined up this way was in 1982, and it won’t occur…

This shot, taken on the night of Aug. 10, 2015, shows lightning flashes in thunderstorms over southern Mexico. Along the right edge bright red and purple streamers can be seen extending high into the…

A Northern View of Saturn’s Stained Moon Iapetus

Here’s a raw image of Saturn’s moon Iapetus, looking down on its northern hemisphere from Cassini on March 31, 2015. The moon’s signature two-toned coloration is evident as its bright icy surface is partially coated by dark material, thought to have been ejected from distant neighbor Phoebe. Iapetus is 914 miles (1,471 km) in diameter, or…

An Absolutely Epic Photo of Humans Returning From Space

It almost doesn’t look real but it is: the return of three humans aboard a Soyuz TMA-14M capsule after spending nearly six months aboard the ISS as part of Expedition 41/42, captured on camera by NASA photographer Bill Ingalls during their sunlit descent via parachute. The Soyuz landed in a remote area near the town of…

Oh What a Relief! Cool 3D Views of the Moon via LROC

Do you have any of those paper 3D viewers around? You know, with the red and blue lenses? If so, pop ’em on and check out the image above from NASA’s Lunar Reconnaissance Orbiter Camera (LROC) showing the crater “Hell Q,” located on the Moon’s southern near side near the brightly-rayed Tycho. You might think…

Only the Penitentes Shall Pass: Snow and Stars Near ESO’s ALMA

I just had to share this beautiful image by ESO photo ambassador Babak Tafreshi; it shows a star-filled night sky above the Chajnantor Plateau on the border of Chile and Bolivia, the site of the Atacama Large Millimeter/submillimeter Array (ALMA) observatory. The site, chosen for its remote location and incredibly clear, dry sky, is one of the best…

Three Worlds, One Shot: a February 2015 Conjunction Event

Did you have clear skies last night? If so, you may have been able to catch the sight above: a conjunction of the crescent Moon and the planets Venus and Mars in the western sky! I captured the photo above with a Nikon D7000 and a Sigma 150-500mm lens. Venus is the brighter object at…
