The black holes are located near the center of the spiral galaxy NGC 3393. Separated by only 490 light years, the black holes are likely the remnant of a merger of two galaxies of unequal mass a billion

The Chandra image  contains a bright X-ray source in the middle, which reveals the position of the supermassive black hole. An optical view of the galaxy from the European Space Observatory's Very

By measuring a peak in the temperature of hot gas in the center of the giant elliptical galaxy NGC 4649, scientists have determined the mass of the galaxy's supermassive black hole. The method, applied

Quantum computers have superior qualities in comparison to the type of computers currently in use. If they are realised, then quantum computers will be able to carry out tasks that are beyond the abilities

This elegant technique, which Titarchuk first suggested in 1998, shows that the black hole in a binary system known as Cygnus X-1 contains 8.7 times the mass of our sun, with a margin of error of only

New research shows that some old stars might be held up by their rapid spins, and when they slow down, they explode as supernovae. Thousands of these "time bombs" could be scattered throughout our Galaxy."We

This result gives a surprising new twist to one of the great mysteries about black holes.Conventional (classical) information can vanish in two ways, either by moving to another place (e.g. across the

Three exceptionally luminous supernovae explosions have been observed in recent years. One of them was first observed using a robotic telescope at the California Institute of Technology's (Caltech) Palomar

For the first time the researchers have discovered that a strong X-ray pulse is emitting from a giant black hole in a galaxy 500 million light years from Earth.The pulse has been created by gas being

The implications could be revolutionary, suggesting that gravity may not be a fundamental force of nature.Prof. Braunstein says: "Our results didn't need the details of a black hole's curved space geometry.

"This black hole is really pushing the limits. For many years astronomers have wanted to know the smallest possible size of a black hole, and this little guy is a big step toward answering that question,"

Astronomers estimate that, on average, about one or two supernovae explode each century in our galaxy. But for Earth's ozone layer to experience damage from a supernova, the blast must occur less than

Named IGR J17091-3624 after the astronomical coordinates of its sky position, the binary system combines a normal star with a black hole that may weigh less than three times the sun's mass. That is near

Many, if not all, galaxies have massive black holes at their centers. But this supermassive black hole is the only one close enough for astronomers to study in detail, so the violent encounter is a unique

Violent video game playing has long been known to increase aggression. This study, conducted by Brad Bushman of The Ohio State University and Bryan Gibson of Central Michigan University, shows that at

You know the feeling. Call it a senior moment, absent-mindedness or a sign of what a busy active brain you have. We’ve all asked ourselves that irritating question: “Where on earth did I leave my car

With its razor- sharp teeth, the fish known as the giant snakehead terrorises the warm waters of south-east Asia.Which is why an angler was particularly startled to hook a 2ft specimen from a river in

The special version of the Tata Nano unveiled in the India city of Mumbai is covered in 80 kilograms of 22 carat gold, 15 kilograms of silver and assorted gemstones. Built as a tribute to 5,000

Genes are found on DNA, a molecule that looks like a twisted ladder. DNA is found in the nucleus of most cells, but it’s also found in mitochondria, which are like factories inside cells that help use

The 2008 Nobel Prize in Chemistry went to the discoverers of the ‘green fluorescent protein’, known as GFP.This remarkable protein was first observed in a species of jellyfish in 1962, and in the
