[CLICK ON IMAGE FOR HIGH RESOLUTION] Caltech / Palomar Observatory / Paul Gardner, Salvatore Grasso, and Ryan Hannahoe Named the Sombrero Galaxy for its hat-like resemblance, M104 features a prominent dust lane and a bright halo of stars and globular clusters. Reasons for the Sombrero’s hat-like appearance include an unusually large and extended central bulge […]
[CLICK ON IMAGE FOR HIGH RESOLUTION] / Bob Franke Beautiful barred spiral galaxy M109, 109th entry in Charles Messier’s famous catalog of bright Nebulae and Star Clusters, is found just below the Big Dipper’s bowl in the northern constellation Ursa Major. In telescopic views, its striking central bar gives the galaxy the appearance of the […]
[Click on image for high resolution.] Credit: Adam Block, Mt. Lemmon SkyCenter, University of Arizona Bright spiral galaxy NGC 3169 appears to be unraveling in this cosmic scene, played out some 70 million light-years away just below bright star Regulus toward the faint constellation Sextans. Its beautiful spiral arms are distorted into sweeping tidal tails […]
[CLICK ON IMAGE FOR HIGH RESOLUTION. Credit: NASA, ESA, and the Hubble Heritage Team] Near the outskirts of the Small Magellanic Cloud, a satellite galaxy some 200 thousand light-years distant, lies 5 million year young star cluster NGC 602. Surrounded by natal gas and dust, NGC 602 is featured in this stunning Hubble image of […]
[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 / Marco Lorenzi] How do clusters of galaxies form and evolve? To help find out, astronomers continue to study the second closest cluster of galaxies to Earth: the Fornax cluster, named for the southern constellation toward which most of its galaxies can be found. Although almost 20 times more […]
[CLICK ON IMAGE FOR HIGH RESOLUTION / Wally Pacholka / AstroPics.com, TWAN A starry band of the Milky Way climbs over Yosemite Valley, Sierra Nevada Range, planet Earth. Jupiter is the brightest celestial beacon on the wintry scene, though. Standing nearly opposite the Sun in the constellation Taurus, the wandering planet joins yellowish Aldebaran and […]
[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 […]
