Black Holes - The Inescapable Truth
Imagine an object that is so dense, it's gravity so strong,
that escape velocity is more than the speed of light.
Twin Black Holes: Never Seen Before
For the first time, we have proof two supermassive black holes exist in the same galaxy, thanks to NASA's Chandra X-ray Observatory. Orbiting each other they will merge several hundred million years from now resulting in a catastrophic event.
Final Death
Throes of Nearby Star Witnessed First-Hand
Final Death Throes of Nearby Star Witnessed First-Hand. It takes only a few
hundred to a thousand years for a dying Sun-like star, many billions of years
old, to transform into a dazzling, glowing cloud called a planetary nebula. This
relative blink in a long lifetime means that a Sun-like star's final moments -
the crucial phase when its planetary nebula takes shape - have, until now, gone
undetected.

Peers into Heart of Dying Star
Hubble Peers into Heart of Dying Star. The Egg Nebula, also known as CRL 2688,
is shown on the left as it appears in visible light with the Hubble Space
Telescope's Wide Field and Planetary Camera 2 (WFPC2) and on the right as it
appears in infrared light with Hubble's Near Infrared Camera and Multi-Object
Spectrometer (NICMOS).

Finds a New Black Hole - and Unexpected New Mysteries
Hubble Finds a New Black Hole - and Unexpected New Mysteries. Confirming the
presence of yet another super-massive black hole in the universe, astronomers
using the Hubble Space Telescope have found unexpected new mysteries. The black
hole, and a 800 light-year-wide spiral-shaped disk of dust fueling it, are
slightly offset from the center of their host galaxy, NGC 4261, located 100
million light-years away in the direction of the constellation Virgo.
'Death
Spiral' Around a Black Hole Yields Tantalizing Evidence of Event Horizon
Death Spiral Around a Black Hole Yields Tantalizing Evidence of Event Horizon.
NASA's Hubble Space Telescope may have, for the first time, provided direct
evidence for the existence of black holes by observing the disappearance of
matter as it falls beyond the event horizon.

Captures an Extraordinary and Powerful Active Galaxy
Hubble Captures an Extraordinary and Powerful Active Galaxy. Resembling a
swirling witch's cauldron of glowing vapors, the black hole-powered core of a
nearby active galaxy appears in this colorful NASA Hubble Space Telescope image.
The galaxy lies 13 million light-years away in the southern constellation
Circinus.
Black
Holes Shed Light on Galaxy Formation
Black Holes Shed Light on Galaxy Formation. Astronomers are concluding that
monstrous black holes weren't simply born big but instead grew on a measured
diet of gas and stars controlled by their host galaxies in the early formative
years of the universe.
A Cosmic
Searchlight
A Cosmic Searchlight. Streaming out from the center of the galaxy M87 like a
cosmic searchlight is one of nature's most amazing phenomena, a
black-hole-powered jet of electrons and other sub-atomic particles traveling at
nearly the speed of light. In this NASA Hubble Space Telescope image, the blue
of the jet contrasts with the yellow glow from the combined light of billions of
unseen stars and the yellow, point-like globular clusters that make up this
galaxy.
