NASA Space Technology NASA Hubble Mission TeamGoddard Space Flight CenterSep 18, 2024This NASA/ESA Hubble Space Telescope image features the spiral galaxy IC 4709 located around 240 million light-years away in the southern constellation Telescopium. Hubble beautifully captures its faint halo and swirling disk filled with stars and dust bands. The compact region at its core might be the most remarkable sight. It holds an active galactic nucleus (AGN).If IC 4709’s core just held stars, it wouldn’t be nearly as bright. Instead, it hosts a gargantuan black hole, 65 million times more massive than our Sun. A disk of gas spirals around and eventually into this black hole, crashing together and heating up as it spins. It reaches such high temperatures that it emits vast quantities of electromagnetic radiation, from infrared to visible to ultraviolet light...

NASA Space Technology Astronomers using the NASA/ESA Hubble Space Telescope have captured an amazing photo of the lens-shaped spiral galaxy IC 4709.IC 4709’s swirling disk filled with stars and dust bands is beautifully captured by Hubble, as is the faint halo surrounding it. The color image is made up of observations from Hubble’s Advanced Camera for Surveys (ACS) in the near-infrared and optical parts of the spectrum. It is based on data obtained through two filters. The color results from assigning different hues to each monochromatic image associated with an individual filter. Image credit: NASA / ESA / Hubble / M. Koss / A. Barth.IC 4709 is located approximately 240 million light-years away in the southern constellation of Telescopium.Otherwise known as ESO 182-14 or LEDA 61835, this galaxy has a diameter of 60,000 light-years.IC 4709...

NASA Space Technology Astronomers using the NASA/ESA Hubble Space Telescope have produced a beautiful image of the barred spiral galaxy UGC 11861.This Hubble image shows UGC 11861, a barred spiral galaxy located 69 million light-years away from Earth in the constellation of Cepheus. Image credit: NASA / ESA / Hubble / C. Kilpatrick.UGC 11861 lies in the northern constellation of Cepheus, approximately 69 million light-years away.Otherwise known as LEDA 67671, IRAS 21557+7301 or TC 609, the galaxy is classified as a barred spiral galaxy and a candidate active galactic nucleus.UGC 11861 is composed of an exponential disk, a central boxy structure and two broad spiral arms.“Among the cloudy gases and the dark wisps of dust, this galaxy is actively forming new stars, visible in the glowing blue patches in its outer arms,” the Hubble astronomers...

NASA Space Technology NASA Hubble Mission TeamGoddard Space Flight CenterJul 26, 2024This NASA/ESAHubble Space Telescopeimage treats viewers to a wonderfully detailed snapshot of the spiral galaxy NGC 3430 that lies 100 million light-years from Earth in the constellation Leo Minor. Several other galaxies, located relatively nearby to this one, are just beyond the frame of this image; one is close enough that gravitational interaction is driving some star formation in NGC 3430 — visible as bright-blue patches near to but outside of the galaxy’s main spiral structure. This fine example of a galactic spiral holds a bright core from which a pinwheel array of arms appears to radiate outward. Dark dust lanes and bright star-forming regions help define these spiral arms.NGC 3430’s distinct shape may be one reason why astronomerEdwin Hubbleused to it to help...
