In a new proof-of-concept observation, astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have measured the mass of the supermassive black hole at the center of NGC 1097 -- a barred spiral
galaxy located approximately 45 million light-years away in the direction of the constellation Fornax.
It is one of the largest and closest barred spirals
to us, and has hosted a large number of supernova explosions.
The Great Barred Spiral
Galaxy is approximately 60 million light-years from Earth and was home to four different observed supernovae, the most recent being SN2012fr.
As in all barred spirals
, NGC 6872 contains a stellar bar component that transitions between the spiral arms and the galaxy's central regions.
Unlike the arms of ordinary spiral galaxies, those of a barred spiral
don't extend all the way into the galactic center.
Washington, Jan 10 ( ANI ): The full beauty of nearby barred spiral
galaxy M83 has been unveiled in all of its glory in a Hubble Space Telescope mosaic image.

Galaxy NGC 6217 This image of barred spiral
galaxy NGC 6217 is the first image of a celestial object taken with the newly repaired Advanced Camera for Surveys (ACS) aboard the Hubble Space Telescope.
Now, however, it is firmly categorised as a barred spiral
galaxy, with loosely wound arms and a relatively small central bulge.
It is a barred spiral
and the brightest member of the Sculptor group of galaxies: the nearest group to our own Local Group.
Also known as Arp 77 and Bennett 10, the galaxy displays an elongated and diffused barred spiral
, extending from the north-west to the south-east, with a bright bar-shaped nucleus that works up to a stellar point.
Washington, January 11 ( ANI ): A team of astronomers has crowned the spectacular barred spiral
galaxy NGC 6872 the largest-known spiral, based on archival data from NASA's Galaxy Evolution Explorer (GALEX) mission.
