[CLICK ON IMAGE FOR HIGH RESOLUTION] An international team of astronomers has used the Hubble Space Telescope to take a census of some of the universe’s earliest galaxies. The results, reported in an upcoming issue of the Astrophysical Journal Letters, confirm that galaxies formed gradually in the early universe and not in a dramatic spurt. […]
[CLICK ON IMAGE FOR HIGH RESOLUTION] In front of a famous background of stars and galaxies lies some of Earth’s more unusual trees. Known as quiver trees, they are actually succulent aloe plants that can grow to tree-like proportions. … Some of the tallest quiver trees in the park are estimated to be about 300 […]
[FOR HIGH RESOLUTION, CLICK ON IMAGE] The galaxy at the image center, Hercules A, appears to be a relatively normal elliptical galaxy in visible light. When imaged in radio waves, however, tremendous plasma jets over one million light years long appear. Detailed analyses indicate that the central galaxy, also known as 3C 348, is actually […]
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] In this stunning vista, based on image data from the Hubble Legacy Archive, distant galaxies form a dramatic backdrop for disrupted spiral galaxy Arp 188, the Tadpole Galaxy. [A] mere 420 million light-years distant toward the northern constellation Draco, … its eye-catching tail is about 280 thousand light-years long […]
[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 […]
[CLICK ON IMAGE FOR HIGH RESOLUTION] Cosmic dust clouds sprawl across a rich field of stars in this sweeping telescopic vista near the northern boundary of Corona Australis, the Southern Crown. Probably less than 500 light-years away and effectively blocking light from more distant, background stars in the Milky Way, the densest part of the […]
[Click on image for high resolution] Scientists have observed what they believe to be the most distant and oldest galaxy ever detected — a discovery which could provide insight into the nature of the universe in its infancy. “This galaxy is the most distant object we have ever observed with high confidence,” Wei Zheng, the […]
[Click on image for high resolution] Giant elliptical galaxy M60 and spiral galaxy NGC 4647 do look like an odd couple in this sharp cosmic portrait from the Hubble Space Telescope. But they are found in a region of space where galaxies tend to gather, on the eastern side of the nearby Virgo Galaxy Cluster. […]
[CLICK ON IMAGE FOR HIGH RESOLUTION] You don’t have to be at Monument Valley to see the Milky Way arch across the sky like this — but it helps. Only at Monument Valley USA would you see a picturesque foreground that includes these iconic rock peaks called buttes. Buttes are composed of hard rock left […]
