Near a Black Hole in the Core of Seyfert Galaxy NGC 4151
Fireworks Near a Black Hole in the Core of Seyfert Galaxy NGC 4151. The Hubble Space Telescope imaging spectrograph simultaneously records, in unprecedented detail, the velocities of hundreds of gas knots streaming at hundreds of thousands of miles per hour from the nucleus of NGC 4151, thought to house a super-massive black hole. This is the first time the velocity structure in the heart of this object, or similar objects, has been mapped so vividly this close to its central black hole.
Hubble Space Telescope Discovers Black Holes in Unexpected Places
Hubble Space Telescope Discovers Black Holes in Unexpected Places. Medium-size black holes actually do exist, according to the latest findings from NASA's Hubble Space Telescope, but scientists had to look in some unexpected places to find them.
Ancient Black Hole Speeds Through Sun's Galactic Neighborhood
Ancient Black Hole Speeds Through Sun's Galactic Neighborhood, Devouring
Companion Star. Data from the Hubble Space Telescope Science Institute's Digitized Sky Survey has played an important supporting role in helping radio and X-ray astronomers discover an ancient black hole speeding through the Sun's galactic neighborhood. The rogue black hole is devouring a small companion star as the pair travels in an eccentric orbit looping to the outer reaches of our Milky Way
galaxy.
Lone Black
Holes Discovered Adrift in the Galaxy
Lone Black Holes Discovered Adrift in the Galaxy. Two international teams of
astronomers using NASA's Hubble Space Telescope and ground-based telescopes in
Australia and Chile have discovered the first examples of isolated stellar-mass
black holes adrift among the stars in our galaxy.
Feasting
Black Hole Blows Bubbles
Feasting Black Hole Blows Bubbles. A monstrous black hole's rude table manners
include blowing huge bubbles of hot gas into space. At least, that's the
gustatory practice followed by the supermassive black hole residing in the hub
of the nearby galaxy NGC 4438. Known as a peculiar galaxy because of its unusual
shape, NGC 4438 is in the Virgo Cluster, 50 million light-years from Earth.
Hubble
Reopens Its Eye on the Universe
Hubble Space Telescope Reopens Its Eye on the Universe. NASA's Hubble Space Telescope is back in
business, as made dramatically evident in stunning new celestial pictures of
remote galaxies and a colorful dying star released today.
Very Long
Baseline Array Reveals Formation Region of Giant Cosmic Jet Near a Bla
Very Long Baseline Array Reveals Formation Region of Giant Cosmic Jet Near a
Black Hole. Space Telescope Science Institute astronomers and their
co-investigators have gained their first glimpse of the mysterious region near a
black hole at the heart of a distant galaxy, where a powerful stream of
subatomic particles spewing outward at nearly the speed of light is formed into
a beam, or jet, that then goes nearly straight for thousands of light-years.
Hubble
Uncovers Dust Disk around a Massive Black Hole
Hubble Space Telescope Uncovers Dust Disk around a Massive Black Hole. Resembling a gigantic
hubcap in space, a 3,700-light-year-wide dust disk encircles a 300-million-
solar-mass black hole in the center of the elliptical galaxy NGC 7052.
Hubble
Finds a Bare Black Hole Pouring Out Light
Hubble Space Telescope Finds a Bare Black Hole Pouring Out Light. Probing the heart of the
active galaxy NGC 6251, NASA's Hubble Space Telescope has provided a
never-before-seen view of a warped disk or ring of dust caught in a blazing
torrent of ultraviolet light from a suspected massive black hole.
NASA's
Hubble Space Telescope Discovers a Disk Fueling a Possible Black Hole
NASA's Hubble Space Telescope Discovers a Disk Fueling a Possible Black Hole.
The giant elliptical galaxy NGC 4261 is one of the 12 brightest galaxies in the
Virgo Cluster, located 45 million light-years away. Photographed in visible
light - white - the galaxy appears as a fuzzy disk of hundreds of billions of
stars. A radio image - orange - shows a pair of opposed jets emanating from the
nucleus and spanning a distance of 88,000 light-years.
