Nasa has revealed a new picture of the oldest stars in the galaxy.
The Hubble Space Telescope captured the shot of what appears to be thousands of cameras flashing at once, but is in fact Messier 107, a cluster of stars which is the most ancient in the galaxy.
The Wide Field Camera of Hubble's Advanced Camera for Surveys was used for the picture.
Messier 107 is just one of the more than 150 globular star clusters found around the Milky Way galaxy, Nasa explains on its website.
Starn clusters are spherical, and contain hundreds of thousands of stars each.
Messier 107 itself is about 20,000 light years from our solar system - too far for humans to likely ever see up close - and is found in the constellation of Ophiuchus.
How such clusters form is not precisely known, and neither is the role they have in the development of a galaxy - but Nasa says its researchers are continuing to study the phonemena.
Nasa said of Messier 107:
French astronomer Pierre Méchain first noted the object in 1782, and British astronomer William Herschel documented it independently a year later. A Canadian astronomer, Helen Sawyer Hogg, added Messier 107 to Charles Messier's famous astronomical catalogue in 1947.
Edge-on View of Near-Earth Asteroids New results from NASA's NEOWISE survey find that more potentially hazardous asteroids, or PHAs, are closely aligned with the plane of our solar system than previous models suggested. PHAs are the subset of near-Earth asteroids (NEAs) with the closest orbits to Earth's orbit, coming within 5 million miles (about 8 million kilometers). They are also defined as being large enough to survive passage through Earth's atmosphere and cause damage on a regional, or greater, scale (NASA/JPL-Caltech)

Unparalleled Views of Earth's Coast With HREP-HICO - Scanning the globe from the vantage point of the International Space Station is about more than the fantastic view. While cruising in low Earth orbit, the space station HICO and RAIDS Experiment Payload-Hyperspectral Imager for the Coastal Ocean, or HREP-HICO, gives researchers a valuable new way to view the coastal zone.
Hinode Mission to Capture Annular Solar Eclipse This Weekend- On May 20-21, 2012 an annular eclipse of the Sun will be visible from within a narrow corridor along Earth's northern Hemisphere -- beginning in eastern Asia, crossing the North Pacific Ocean, and ending in the western United States. A partial eclipse will be visible from a much larger region covering East Asia, North Pacific, North America and Greenland (Hinode)
After spending 19 weeks working in one place while solar power was too low for driving during the Martian winter, NASA's Mars Exploration Rover Opportunity is on the move again. The winter worksite was on the north slope of an outcrop called Greeley Haven. The rover used its rear hazard-avoidance camera to complete the May 8 drive (NASA/JPL/Cornell/University of Arizona)
Psychedelic Space - This is a composite of a series of images photographed from a mounted camera on the Earth-orbiting International Space Station, from approximately 240 miles above Earth. Expedition 31 Flight Engineer Don Pettit said of the about photographic techniques used to achieve the images: "My star trail images are made by taking a time exposure of about 10 to 15 minutes. However, with modern digital cameras, 30 seconds is about the longest exposure possible, due to electronic detector noise effectively snowing out the image. To achieve the longer exposures I do what many amateur astronomers do. I take multiple 30-second exposures, then 'stack' them using imaging software, thus producing the longer exposure." A total of 18 images photographed by the astronaut-monitored stationary camera were combined to create this composite (NASA)
Days of 'Gizmo' Launches Return-NASA Team to Test New Vehicle-Descent Technologies, NASA technologists will get a chance next summer to relive the good old days when Agency engineers would affix space-age gizmos to rockets just to see if the contraptions worked.
