Like brush strokes on a canvas, ridges of color seem to flow across the Lagoon Nebula, a canvas nearly 3 light-years wide. The colors map emission from ionized gas in the nebula were recorded by the Hubble Space Telescope's Advanced Camera for Surveys. Also known as M8, the nebula is a star-forming region in the constellation Sagittarius. Hubble's remarkably sharp, close-up view reveals undulating shapes sculpted by the energetic light and winds from the region's new born stars. Of course, the Lagoon Nebula is a popular target for earthbound skygazers, too.
A few newbies if you can call them that. Just love the imagery NASA provides me with this Firefox gadget
Crackling with Solar Flares
Fast-growing sunspot 1112 is crackling with solar flares. So far, none of the blasts has hurled a substantial CME, or coronal mass ejection, toward Earth. In addition, a vast filament of magnetism is cutting across the sun's southern hemisphere. This filament is so large it spans a distance greater than the separation of Earth and the moon. A bright 'hot spot' just north of the filament's midpoint is UV radiation from sunspot 1112. The proximity is no coincidence; the filament appears to be rooted in the sunspot below. If the sunspot flares, it could cause the entire structure to erupt. Thus far, none of the flares has destabilized the filament..
Sun and Moon
On Oct. 7, 2010, NASA's Solar Dynamics Observatory, or SDO, observed its first lunar transit when the new moon passed directly between the spacecraft (in its geosynchronous orbit) and the sun. With SDO watching the sun in a wavelength of extreme ultraviolet light, the dark moon created a partial eclipse of the sun.
This artist's impression shows how the Arches star cluster appears from deep inside the hub of our Milky Way Galaxy. Hidden from our direct view, the massive cluster lies 25,000 light-years away and is the densest known gathering of young stars in our galaxy. The illustration is based on infrared observations from Hubble and with ground-based telescopes, which pierced our galaxy's dusty core and snapped images of the luminous cluster of about 2,000 stars.
