Super Massive Black Holes Lurking In The Hearts Of Galaxies
Supermassive black holes are the most destructive force in the Universe, with a compact energy source of enormous strength
and a mass of an order of magnitude between 105 and 1010 (hundreds of thousands and tens of billions) of solar masses!
They are so bizarre that until recently scientists did not believe they existed.
Flat Pancake-Shaped Galaxy Harbors Three Black Holes
Universe is still a big mystery. The bright galaxy NGC 3621 is the so-called "flat galaxy" which appears to be just a classical spiral.
But it is rather unusual astronomical object
Bulgeless and therefore described as a pure-disc galaxy, NGC 3621 lies far beyond the local group of galaxies, some 22 million
light-years away in the constellation of Hydra (The Sea Snake)...
WISE Hunts Voracious Objects
With Jets Pointing Right Towards Earth
WISE continues its hunt for voracious, supermassive black holes known as blazars,
one of the most fascinating, rare and still unknown cosmic phenomena.
Their jets are streaming outward at nearly the speed of light and point towards our planet.
They are unique evidence for the most extreme speeds and energies known in the extreme Universe.
"Ghost Object" Appears After Black Hole Eruption
A cosmic "ghost" lurking around a distant supermassive black hole provides astronomers with valuable information about the early Universe.
"We'd seen this fuzzy object a few years ago, but didn't realize until now that we were seeing a ghost", said Andy Fabian of the Cambridge
University in the United Kingdom.
Black Hole In Scorpius Seen Firing Fast Cosmic Bullets
Located about 28,000 light-years from Earth in the constellation Scorpius, there is a black hole named H1742-322. Racing outward at about one-quarter the speed of light, "bullets"
of ionized gas are thought to arise from a region located just outside the black hole's event horizon, the point beyond which nothing can escape.
Intimate Connection Between Black Holes And New-Born Stars
Astronomers have known for some time that black holes and
supermassive black holes
accretion and star formation appear intimately connected.
However, it does not mean that powerful gravitational forces of the black holes disrupt surrounding material in their vicinity.
Power To See Most Distant Objects In The Universe
The 3C294, is one of the most distant galaxies recorded by Chandra, the most sophisticated X-ray observatory ever built.
The cluster 3C294 is even 40 percent farther (!) than the next most distant x-ray galaxy cluster.
Chandra focus on X-rays from high-energy regions of the Universe and see the invisible.
It is so sensitive that it can capture images of particles as they disappear into a black hole deep in outer space.
