Maijishan Caves, Tianshui, China
The Maijishan Grottoes (simplified Chinese: 麦积山石窟;
traditional Chinese: 麥積山石窟; pinyin: Màijīshān Shíkū) are a
series of 194 caves cut in the side of the hill of
Majishan in Tianshui, Gansu Province, northwest China.
This example of rock cut architecture contains over 7,200
Buddhist sculptures and over 1,000 square meters of
murals. Construction began in the Later Qin era (384-417 CE)

NGC 3521 - Galaxy in Leo with Large Halo
Galaxy NGC 3521 lies at a distance of 35 million light years in the constellation Leo. The galaxy has an unusually large hazy halo. At magnitude 9, it is as bright as many of the galaxies included by Messier in his famous catalog.

Stephans Quintet
A clash among members of a famous galaxy quintet reveals an assortment of stars across a wide colour range, from young, blue stars to aging, red stars.
This portrait of Stephan's Quintet, also known as the Hickson Compact Group 92, was taken by the new Wide Field Camera 3 (WFC3) aboard the NASA/ESA Hubble Space Telescope. Stephan's Quintet, as the name implies, is a group of fiv
e galaxies. The name, however, is a bit of a misnomer. Studies have shown that group member NGC 7320, at upper left, is actually a foreground galaxy that is about seven times closer to Earth than the rest of the group.
Three of the galaxies have distorted shapes, elongated spiral arms, and long, gaseous tidal tails containing myriad star clusters, proof of their close encounters. These interactions have sparked a frenzy of star birth in the central pair of galaxies. This drama is being played out against a rich backdrop of faraway galaxies.
The image, taken in visible and near-infrared light, showcases WFC3's broad wavelength range. The colours trace the ages of the stellar populations, showing that star birth occurred at different epochs, stretching over hundreds of millions of years. The camera's infrared vision also peers through curtains of dust to see groupings of stars that cannot be seen in visible light.
NGC 7319, at top right, is a barred spiral with distinct spiral arms that follow nearly 180 degrees back to the bar. The blue specks in the spiral arm at the top of NGC 7319 and the red dots just above and to the right of the core are clusters of many thousands of stars. Most of the Quintet is too far away even for Hubble to resolve individual stars.
Continuing clockwise, the next galaxy appears to have two cores, but it is actually two galaxies, NGC 7318A and NGC 7318B. Encircling the galaxies are young, bright blue star clusters and pinkish clouds of glowing hydrogen where infant stars are being born. These stars are less than 10 million years old and have not yet blown away their natal cloud. Far away from the galaxies, at right, is a patch of intergalactic space where many star clusters are forming.
NGC 7317, at bottom left, is a normal-looking elliptical galaxy that is less affected by the interactions.
Sharply contrasting with these galaxies is the dwarf galaxy NGC 7320 at upper left. Bursts of star formation are occurring in the galaxy's disc, as seen by the blue and pink dots. In this galaxy, Hubble can resolve individual stars, evidence that NGC 7320 is closer to Earth. NGC 7320 is 40 million light-years from Earth. The other members of the Quintet reside about 300 million light-years away in the constellation Pegasus.
These more distant members are markedly redder than the foreground galaxy, suggesting that older stars reside in their cores. The stars' light also may be further reddened by dust stirred up in the encounters.
Spied by Edouard M. Stephan in 1877, Stephan's Quintet is the first compact group ever discovered.
WFC3 observed the Quintet in July and August 2009. The composite image was made by using filters that isolate light from the blue, green and infrared portions of the spectrum, as well as emission from ionised hydrogen.
These Hubble observations are part of the Hubble Servicing Mission 4 Early Release Observations. NASA astronauts installed the WFC3 camera during a servicing mission in May to upgrade and repair the 19-year-old Hubble telescope.

N 164 Nebula in LMC
N 164, a bright nebula, the glow of which is caused by hot stars inside it. The heating of the gas by these stars increases the pressure and causes such nebulae to expand, pushing outwards against their surroundings. A careful look at this nebula reveals locations where the expansion is encountering resistance by denser clouds of gas, producing bright, thin rims. The sky field measures 3.6 x 3.5 arcmin. North is up and East is left.

A TORNADO ROPING OUT IN NORTH DAKOTA
Image Credit : Mitch Dobrowner
In this incredible photograph by Mitch Dobrowner we see a tornado in North Dakota dying out. These tornadoes are said to be “roping out”, or becoming a “rope tornado”. When they rope out, the length of their funnel increases, which forces the winds within the funnel to weaken due to conservation of angular momentum
A tornado is a violently rotating column of air that is in contact with both the surface of the earth and a cumulonimbus cloud or, in rare cases, the base of a cumulus cloud. They are often referred to as twisters or cyclones, although the word cyclone is used in meteorology, in a wider sense, to name any closed low pressure circulation
This amazing capture was recently featured as National Geographic’s Photo of the Day. It is also a part of a July 2012 feature story entitled Epic Storms that contains an incredible gallery by Dobrowner of black and white storm photographs. You can see the gallery here on National Geographic.
The feature story and accompanied gallery were the result of a collaboration between Dobrowner and storm chaser Roger Hill. Over a course of three years, the pair have stalked some 45 weather systems over 16 states and 40,000 miles. Dobrowner works in black and white because, “color seems too everyday”

Starry Starty Skies
2012 September 17
Astronomers have discovered two gas giant planets orbiting stars in the Beehive cluster, a collection of about 1,000 tightly packed stars.
The newfound planets are not habitable, and are considered to be two hot Jupiters, which are massive gas planets.
Each of the hot Jupiter planets circle a different sun-like star in the Beehive Cluster, which is a collection of about 1,000 stars that appear to be swarming around a common center.
This cluster of stars was born at about the same time and out of the same giant cloud of material. The stars born in the cluster share a similar chemical composition, and they remain loosely bound together by mutual gravitational attraction.

Andromeda in Red
This image of Andromeda, in red, highlights the dust that clings to Andromeda's spiral arms. The dust is radiating heat from hot, newborn stars. Another view focused in on the oldest stars in Andromeda, revealing a warp in the galaxy's disk -- the result of a collision with another galaxy long ago.

In that darkest night, the Milky Way could be observed with our naked eyes. I carefully set my camera on the spot while worrying about the incoming tide, even reducing its level from time to time. My brightest wide angel is Carl Zeiss 21/2.8 and it was used in this shot for foreground. I took two shots, one with 20 minutes @ f8.0 and iso 400 to make sure the rock's sharpness. I used hyper focus in the first shot.
Another shot was taken with about 3 minutes @ f4.0 and iso 3200. I lightened the rock, located in the foreground, by light painting it with my small torch.

A Solar Filament Erupts
Image Credit: NASA's GSFC, SDO AIA Team
http://apod.nasa.gov/apod/ap120917.html
What's happened to our Sun? Nothing very unusual -- it just threw a filament. At the end of last month, a long standing solar filament suddenly erupted into space producing an energetic Coronal Mass Ejection (CME). The filament had been held up for days by the Sun's ever changing magnetic field and the timing of the eruption was unexpected. Watched closely by the Sun-orbiting Solar Dynamics Observatory, the resulting explosion shot electrons and ions into the Solar System, some of which arrived at Earth three days later and impacted Earth's magnetosphere, causing visible aurorae. Loops of plasma surrounding an active region can be seen above the erupting filament in the ultraviolet image. If you missed this auroral display please do not despair -- over the next two years our Sun will be experiencing a solar maximum of activity which promises to produce more CMEs that induce more Earthly auroras.
