[CLICK ON IMAGE FOR HIGH RESOLUTION, Adam Block, Mt. Lemmon SkyCenter, U. Arizona] In this image taken Jan. 23rd, [the arrow points to ] a new supernova, now cataloged as SN 2014J, in the nearby bright galaxy M82. Located near the Big Dipper in planet Earth’s sky, M82 is also known as the Cigar Galaxy…. […]
[FOR HIGH RESOLUTION, CLICK ON IMAGE] / Adam Block, Mt. Lemmon SkyCenter, U. Arizona] The beautiful, dusty nebula NGC 2170 shines at the upper left. Reflecting the light of nearby hot stars, NGC 2170 is joined by other bluish reflection nebulae, a compact red emission region, and streamers of obscuring dust against a backdrop of […]
[CLICK ON IMAGE FOR HIGH RESOLUTION], NASA, ESA, and the Hubble Heritage The Ring Nebula (M57) is probably [next to Saturn’s rings] the most famous celestial band. … The recent mapping of the expanding nebula’s 3-D structure, based in part on this clear Hubble image, indicates that the nebula is a relatively dense, donut-like ring […]
[FOR HIGH RESOLUTION, CLICK ON IMAGE / Hubble Legacy Archive A gorgeous spiral galaxy some 100 million light-years distant, NGC 1309 lies on the banks of the constellation of the River (Eridanus). NGC 1309 spans about 30,000 light-years, making it about one third the size of our larger Milky Way galaxy. Bluish clusters of young […]
[CLICK ON IMAGE FOR HIGH RESOLUTION / Martin Pugh] AE Aurigae is called the flaming star. The surrounding nebula IC 405 is named the Flaming Star Nebula and the region seems to harbor smoke, but there is no fire. … The bright star AE Aurigae, visible near the nebula center, is so hot it is […]
FOR HIGH RESOLUTION, CLICK ON IMAGE. Wisps like this are all that remain visible of a Milky Way star. About 9,000 years ago that star exploded in a supernova leaving the Veil Nebula, also known as the Cygnus Loop. At the time, the expanding cloud was likely as bright as a crescent Moon, remaining visible […]
[CLICK ON IMAGE FOR HIGH RESOLUTION] Is this what will become of our Sun? Quite possibly. The bubble of expanding gas pictured above is the planetary nebula PK 164 +31.1, the remnants of the atmosphere of a Sun-like star expelled as its supply of fusion-able core hydrogen became depleted. Visible near the center of the […]
[CLICK ON IMAGE FOR HIGH RESOLUTION.] This lovely blue cosmic cloud begins the van den Bergh Catalog (vdB) of stars surrounded by reflection nebulae. Interstellar dust clouds reflecting the light of the nearby stars, the nebulae usually appear blue because scattering by the dust grains is more effective at shorter (bluer) wavelengths. The same type […]
[CLICK ON IMAGE FOR HIGH RESOLUTION] What did the first galaxies look like? To help answer this question, the Hubble Space Telescope has just finished taking the eXtreme Deep Field (XDF), the deepest image of the universe ever taken in visible light. Pictured above, the XDF shows a sampling of some of the oldest galaxies […]
It’s easy to get lost following the intricate filaments in this detailed mosaic image of faint supernova remnant Simeis 147 (S147). Also cataloged as Sh2-240, it covers nearly 3 degrees or 6 full moons on the sky. That’s about 150 light-years at the stellar debris cloud’s estimated distance of 3,000 light-years. … This sharp composite […]
