New Study Finds Middle Child of Black Hole Family - Yahoo! News
The "just right"-sized candidate is an X-ray source in the NGC 5408 galaxy, 15.8 million light-years away from Earth in the constellation Centaurus.
"Intermediate-mass black holes contain between 100 and 10,000 times the sun's mass," said Tod Strohmayer, an astrophysicist at NASA's Goddard Space Flight Center in Greenbelt, Md. "We observe the heavyweight black holes in the centers of galaxies and the lightweight ones orbiting stars in our own galaxy. But finding the 'tweeners' remains a challenge."

Scientists Seek Gravity's Imprint in Big Bang Glow: Discovery News
Irene Klotz, Discovery News
July 1, 2009 -- A search for gravitational waves stemming from the creation of the universe commences this week with an array of new detectors sensitive enough to measure signals as faint as a billionth of a volt.
The experiment, called QUIET, is the latest attempt to find theoretical ripples in the expanse of space caused by the Big Bang explosion some 14 billion years ago.
Albert Einstein predicted the existence of gravity waves which would have alternatively compressed and exp

The Great Blue Hole - Belize Lighthouse Reef
The diameter of the circular reef area stretches for about 1,000 feet and provides an ideal habitat for corals to attach and flourish. The coral actually breaks the surface in many sections at low tide. Except for two narrow channels, the reef surrounds the hole. The hole itself is the opening to a system of caves and passageway that penetrate this undersea mountain. In various places, massive limesto
