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
New observations from NASA’s Spitzer Space Telescope provide strong evidence that the slender, bulge less galaxies can, like their heftier counterparts, harbor supermassive black holes
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
The Herschel Infrared Space Observatory discovered that galaxies do not always need to collide with each other to drive vigorous star birth. The finding overturns
Is now the third year of the Royal Observatory’s competition to uncover the best photographs of stars, planets, galaxies and more. They received nearly 800
Physicists and astronomers have long believed that the universe has mirror symmetry, like a basketball. But recent findings from the University of Michigan suggest that
Astronomer Edwin Hubble gave us our first basic galaxy classification. Using photographic plates, Hubble derived a simplistic system based on three visually known structures: elipitical,
This image of super-cluster Abell 2744 captures the wreckage of a collision between four smaller galaxy clusters. New data let astronomers map the positions of
To find out, a group of researchers led by Stanford University astrophysicist Risa Wechsler compared the Milky Way to similar galaxies and found that just
This diagram (above) illustrates two ways to measure how fast the universe is expanding. In the past, distant supernovae, or exploded stars, have been used
