Many of the photographs in this entry and the next few are from APOD, Astronomy Photo of the Day [recommended] or the NASA Image of the Day [also recommended].

Regarding this first image which got a lot of attention: it’s not a photograph, per se. It’s a rendering of data. Mind blowing in more than one way.

The long shadow of Mt. Rainier  Bad Astronomy  Discover Magazine

Here in Boulder we get magnificent sunsets, especially in the summer when the clouds interplay with the mountains to the west. But I have never seen anything like this: the shadow of Washington state’s Mt. Rainier cast along the clouds at sunrise:

That’s amazing. Mt. Rainier is a volcano, climbing to a height of over 14,000 feet (4300 meters).

In November and December 2011, professional and amateur astronomers reveled in observing a sun-grazing comet that dove close to the Sun and survived for a return flight back to the outer solar system. Astronauts on the International Space Station (ISS) enjoyed their own surreal view of the comet as it appeared on Earth’s horizon on the day of the solstice.

ISS Commander Dan Burbank captured a series of digital photographs of Comet Lovejoy on December 21, 2011, as it rose above Earth’s limb

Nickel Cobalt


This up to 1000 years old snow has metamorphosed into highly pressurized  glacier ice that contains almost no air bubbles. Thus it absorbs the  visible light despite the scattered shortest blue fraction, giving it  its distinct deep blue waved appearance. This cavity in the glacier ice  formed as a result of a glacial mill, or moulin.
Rain and meltwater on  the glacier surface is channelled into streams that enter the glacier at  crevices. The waterfall melts a hole into the glacier while the ponded  water drains towards lower elevations by forming long ice caves with an  outlet at the terminus of the glacier. The fine grained sediments in the  water along with wind blown sediments cause the frozen meltwater stream  to appear in a muddy colour while the top of the cave exhibits the deep  blue colour.
Due to the fast movement of the glacier of about 1 m per  day over uneven terrain this ice cave cracked up at its end into a deep  vertical crevice, called cerrac. This causes the indirect daylight to  enter the ice cave from both ends resulting in homogeneous lighting of  the ice tunnel.

Each week, The Big Picture features one long page full of photos of a current event. These photos are always very professional and gorgeous, appearing in a large format. My one complaint is that scrolling inevitably fails to line most of the photos up correctly; I wish there were a better mechanism for moving between photos.

2012 Marking the New Year – The Big Picture – Boston.com

Around the world people celebrated with fireworks, kisses, blessings, gatherings, cheers, watching the sunrise and plunges into icy bodies of water to welcome in a new year. Here’s a look back at how some of them marked the transition. – Lloyd Young (41 photos total)

A cloud of ash billowing from Puyehue volcano near Osorno in southern Chile, 870 km south of Santiago, on June 5. Puyehue volcano erupted for the first time in half a century on June 4, 2011, prompting evacuations for 3,500 people as it sent a cloud of ash that reached Argentina. The National Service of Geology and Mining said the explosion that sparked the eruption also produced a column of gas 10 kilometers (six miles) high, hours after warning of strong seismic activity in the area.
