Researchers Explain Why Supermassive Black Holes Eat Less Material Than Expected
2013-08-30 08:51:11

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.

Milky Way Gas Cloud Creates Multiple Images Of Distant Quasar
2013-08-29 03:49:01

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.

Space Slinky Video Compiled From Hubble Images

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.

Unraveling Galactic History Begins With A Black Hole's Spin
2013-07-30 14:11:38

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.

Milky Way Black Hole Rips Apart Gas Cloud

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.

Monstrous Stellar Collisions Not Expected To Occur Anytime Soon
2013-07-11 14:32:31

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.

Aircraft Telescope Images Ring Of Dust Surrounding Black Hole
2013-07-10 13:34:10

Astronomers using a telescope attached to a modified Boeing 747SP aircraft have captured new images of a ring of gas and dust seven light-years in diameter surrounding the supermassive black hole at the center of the Milky Way.

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...

bretelles
  • In dressmaking, straps running from the belt in front over the shoulders to the belt in the back, with more or less elaboration of trimming and outline. They usually broaden at the shoulder and narrow toward the waist.
The word 'bretelles' comes from a French word meaning 'braces'.
