Astronomers reveal supermassive black hole's intense magnetic field Astronomers from Chalmers University of Technology have used the giant telescope Alma to reveal an extremely powerful magnetic field very close to a supermassive black hole in a distant galaxy. The results appear in the 17 April 2015 issue of the journal Science.
In the Center of Spiral Galaxy NGC 3521 - Its central region is shown in this dramatic image, constructed from data from the Hubble Space Telescope. The close-up view highlights this galaxy's characteristic multiple, patchy, irregular spiral arms laced with dust and clusters of young, blue stars. In contrast, many other spirals exhibit grand, sweeping arms.
Astronomy Picture of the Day: 11/30/13 - The Dolphin Nebula This is SH2-188 - otherwise known as the Dolphin Nebula - a planetary nebula that's located approximately 850 light-years from Earth in the constellation of Cassiopeia A. In the past, SH2-188 was thought to be the remnant of a supernova explosion that appeared in 1965 (it took the light 850 years to reach us), but the nebula was later confirmed to be an asymmetrical planetary nebula with a crescent-like shape.
