This image resembling Vincent van Gogh's painting, "Starry Night," is an expanding halo of light around a distant star, named V838 Monocerotis (V838 Mon). This Hubble Telescope image was obtained with the Advanced Camera for Surveys on February 8, 2004.

For the 15th anniversary of the Hubble Space Telescope, scientists used the ACS, Hubble's newest camera, to record a new region of the eerie-looking Eagle Nebula, producing an image with stunning detail. The new Eagle Nebula image reveals a tall, dense tower of gas being sculpted by ultraviolet light from a group of massive, hot stars.

The Hubble Space Telescope captured this interesting photo of the inside of an inflating, see-through space bubble. The transparent bubble is considered a nebula, and it is called N44F. The scene is about 160,000 light-years away in a neighboring galaxy called the Large Magellanic Cloud document.body.clientWidth*0.5) {this.resized=true;this.width=document.body.clientWidth*0.5;this.style.cursor='pointer';} else {this.onclick=null}" alt="" border="0"> Electric Earth -------------------------------------------------------------------------------- Purple Wonder -------------------------------------------------------------------------------- Time-lapse photography captures multiple cloud-to-ground lightning strokes during a night-time thunderstorm.

At the top of this image wispy dark clouds hang delicately in the foreground of diffuse glowing hydrogen gas. These lead further down towards a very bright, red arc of gas that seems to shield luminous and hot stars beneath it. Presumably the birth and subsequent energetic radioactive output of these stars causes the gas to glow very brightly. Even though these stars have strived to push away all of the gas and dust near them; thicker portions remain (the mountains of dark nebulosity) and continue to scatter light which color the area with hints of blue and purple. NGC 6559 can be found in most wide field images of the Lagoon Nebula.
