Latest Supermassive black holes Stories
Around 2 million years ago, the supermassive black hole at the center of our galaxy erupted in a blaze of glory big enough to leave a residual glow that can still be seen today.
A long-standing mystery concerning super massive black holes at the center of galaxies has been solved by a team of astronomers using NASA’s super-sensitive Chandra X-ray space telescope.
Using the National Science Foundation's Very Long Baseline Array radio telescope system, astronomers have for the first time managed to capture an image of a distant quasar split into multiple images due to the effects of a cloud of ionized gas in the Milky Way.
Astronomers are hoping to gain new insight in the role that black holes play in galaxy evolution thanks to a new series of time-lapse movies compiled from over a decade’s worth of observations from NASA’s Hubble Space Telescope.
Recently, a team of three 3rd year students studying at the Niels Bohr Institute undertook a week long observation at the Nordic Optical Telescope in La Palma, Spain. Their mission: to take deeper, follow-up observations of a puzzling object that had been recently discovered.
A supermassive black hole is believed to sit at the center of each large galaxy and a new technique designed to detect the dark abyss's spin could be the key to unraveling a galaxy's history.
The European Southern Observatory's Very Large Telescope has helped astronomers catch a supermassive black hole ripping apart a gas cloud for the first time.
Astrophysicists from the Astronomical Observatory of the Faculty of Physics at the University of Warsaw say the next collision of monstrous stars will not occur until billions of years from now.
Supermassive Black Hole -- A Supermassive black hole is a black hole with a mass in the range of millions or billions solar masses. A supermassive black hole has some interesting properties differing from his low-mass cousins: -- The average density of a supermassive black hole can be very low, and actually can be lower than water's density. This happens because the black hole diameter increases linearly with mass, and consequently density drops much faster. -- Strong tidal...
Seyfert Galaxy -- Seyfert galaxies are spiral or irregular galaxies containing an extremely bright nucleus, most likely caused by a supermassive black hole, that can sometimes outshine the surrounding galaxy. The light from the central nucleus varies in less than a year, which implies that the emitting region must be less than one light year across. They are named for the astronomer Carl Seyfert, who studied them extensively in the 1940s. They are a subclass of active galactic nuclei....
Quasar -- A quasar (from quasi-stellar radio source) is an astronomical object that looks like a star in optical telescopes (i.e. it is a point source), but has a very high redshift. The general consensus is that this high redshift is cosmological, the result of Hubble's law and that their redshift indicates that they are typically very distant from Earth; we observe them as they were several billions of years ago. Since we can see them despite their distance, they must emit more...
