Explanation:  To celebrate 25 years (1990-2015) of exploring the Universe from low Earth orbit, the Hubble Space Telescope’s cameras were used to revisit its most iconic image. The result is this sharper, wider view of the region dubbed the Pillars of Creation, first imaged by Hubble in 1995. Stars are forming deep inside the towering structures. The light-years long columns of cold gas and dust are some 6,500 light-years distant in M16, the Eagle Nebula, toward the constellation Serpens. Sculpted and eroded by the energetic ultraviolet light and powerful winds from M16’s cluster of young, massive stars, the cosmic pillars themselves are destined for destruction. But the turbulent environment of star formation within M16, whose spectacular details are captured in this Hubble visible-light snapshot, is likely similar to the environment that formed our own Sun.

OVER THE TOP

Explanation: The central bulge of our Milky Way Galaxy rises above a sea of clouds in this ethereal scene. An echo of the Milky Way’s dark dust lanes, the volcanic peak in foreground silhouette is on France’s Réunion Island in the southern Indian Ocean.

 Taken in February, the photograph was voted the winner of the 2014 International Earth and Sky Photo Contest’s Beauty of the Night Sky Category. This and other winning and noteable images from the contest were selected from over a thousand entries from 55 countries around planet Earth. Also featured in the contest compilation video (vimeo), the moving images are a testament to the importance and beauty of our world at night.

Aurora and Unusual Clouds Over Iceland

Aurora and Unusual Clouds Over Iceland

What’s happening in the sky? On this cold winter night in Iceland, quite a lot. First, in the foreground, lies the largest glacier in IcelandVatnajokull. On the far left, bright green auroras appear to emanate from the glacier as if it was a volcano. Aurora light is reflected by the foreground lake Jökulsárlón.

On the far right is a long and unusual lenticular cloud tinged with green light emitted from another aurora well behind it. Just above this lenticular cloud are unusual iridescent lenticular clouds displaying a broad spectral range of colors. Far beyond the lenticular is the setting Moon, while far beyond even the Moon are setting stars. The above image was captured in late March of 2012.

Gigantic Hurricane on Saturn

Cassini captures gigantic hurricane on Saturn in exquisite detail

Saturn, for example, has an odd hexagonal pattern in the clouds at its north pole, and when the planet tilted enough to illuminate it, the light revealed a giant hurricane embedded in the center of the hexagon. Scientists think the immense storm may have been there for years.

The photo below was taken by the Cassini orbiter in June of 2013.

October Aurora in Prairie Skies

The recent US government shutdown meant a lot of things to a lot of people.

To me, it meant that NASA’s Astronomy Photo of the Day was not up and running!

Luckily, things are back to abnormal now so imagine my delight at seeing this photo, courtesy of NASA.

NASA’s explanation: Wind and spaceweather are transformed in this haunting night skyscape. The prairie windmill and colorful auroral display were captured on October 1, from central South Dakota, USA, as a good season for aurora hunters came with longer autumn nights. From green to rarer reddish hues, the northern lights are sparked by the geomagnetic storms caused by solar activity. These extend far above the cloud bank to altitudes well over 100 kilometers, against the backdrop of distant stars in the northern night. Visual double star Mizar, marking the middle of the Big Dipper’s handle, is easy to spot at the left edge of the frame. The dipper’s North Celestial Pole pointers Merak and Dubhe line up vertically near picture center.

Welcome back, NASA. We missed you!
