Galaxies with the most powerful, active, supermassive black holes at their cores produce fewer stars than galaxies with less ones. This is from new data from the Herschel Space Observatory. Image Credit: NASA/JPL-Caltech
On 24 April 1990, NASA/ESA Hubble Space Telescope was launched into space.
To celebrate the 22nd anniversary of the Hubble Space Telescope this month, episode 54 of the Hubblecast gives a slideshow of some of the best images from over two decades in orbit, set to specially commissioned music. credit: ESA/Hubble
Sombrero Galaxy, one of the largest galaxies in the nearby Virgo Cluster of Galaxies. The dark band of dust that obscures the mid-section of the Sombrero Galaxy in optical light actually glows brightly in infrared light.
In celebration of the twenty-first anniversary of the Hubble Space Telescope’s deployment in April 2011, astronomers at the Space Telescope Science Institute pointed Hubble’s eye to an especially photogenic group of interacting galaxies called Arp 273.
Using the Hubble space telescope, astronomers have captured a direct image of the disk surrounding a black hole. Among the brightest objects in the sky, quasars are short-lived phenomena that only existed during the earliest eras of the universe.
An image taken by planetary scientist Larry Sromovsky, with the Gemini 8.1 meter telescope, shows a bright patch that is thought to be an eruption of methane ice high in the atmosphere. Amateur astronomers with large telescopes and CCD cameras are being urged to turn them on the distant planet Uranus following reports of the appearance of a brilliant new feature.
This interacting pair of galaxies is included in Arp’s catalog of peculiar galaxies as number 148. Arp 148 is the staggering aftermath of an encounter between two galaxies, resulting in a ring-shaped galaxy and a long-tailed companion.
