Astronomers Find Evidence of the Youngest Black Hole

Article Category: Business

Author Name: Amanda xzh

15 noon EST, NASA announced a news conference in Washington, astronomers using the Chandra X-ray space telescope and other equipment may be observed in the youngest human ever found a black hole - a distance of about 50 million Earth light of the M100 galaxy of the supernova "SN1979C" formed after the collapse of objects, its birth was observed in the moment, so far only 30 years.

Scientists said that the black hole mass is about 5 times the sun, about 50 million light years from Earth, the observation that there are 5,000 years or so delay, saying that "young" is not it the age of only 30 years old, but that It was observed during the formation of the state to the time in 30 years. However, when people did not know it was a black hole, recent observations have proved that they have may be the black hole.

Help scientists better understand how stars explode, the explosion after a black hole or a neutron star produced by

Astronomers are excited that this new discovery as the observation of "infancy" of the object to provide an excellent opportunity to help scientists better understand how stars explode, the explosion after a black hole or a neutron star produced, but also a help to understand the Milky Way and other galaxies, the number of black holes.

Black holes are objects of a strong gravitational field, even light can not escape, so people can not directly observe a black hole, but around the object by measuring its role and influence to the existence of indirect observation or speculation.

When massive stars collapse supernova is the violent explosions. "SN1979C" by an amateur astronomer discovered in 1979, scientists thought it was a mass of more than 20 times the sun, the stars and the formation of a supernova explosion. In theory, the quality ranged from 8 to 25 times the sun between the massive stars in the run out of fuel, it will support its own weight, sudden loss of pressure, there is an end in the explosion, the core will collapse into a black hole or a neutron stars. Neutron stars are the quality is not as stellar black holes can form when the form at the end of life as a celestial body.

Code-named "SN1979C" the remains of a supernova explosion is very likely a black hole, but can not completely rule out other possibilities

According to Chandra X-ray Space Telescope, NASA's Swift detectors, the European Space Agency XMM Newton Telescope and other astronomical data obtained from the supernova "SN1979C" formed after the collapse of objects is a bright X-ray source. 1995 to 2007 observation period, it remained stable, indicating that this object may be a black hole, is engulfed by the supernova from the companion star's material needs or its own "appetite."

Previously, scientists have detected the depths of the universe relative to Earth, many of the emerging black hole. NASA announced the discovery on the 15th, Harvard - Smithsonian Center for Astrophysics researcher Daniel Patrick Arnold said: "If interpreted correctly, it is observed from Earth humans, a recent instance of a black hole was born. "

However, astronomers have noted that, while code-named "SN1979C" the remains of a supernova explosion is very likely a black hole, but can not rule out other explanations, such as a high-energy particles associated with strong winds, rapidly spinning neutron stars may also produce The observed X-ray radiation. They think that, regardless of what kind of interpretation is confirmed, the new discovery is an astronomical event observed from the beginning to provide the best opportunity. Found signs of this black hole show that the universe is always in constant motion and galaxies, the stars are born, but also death, while the same black hole in the birth, growth, the natural process of aging.

Disappointed

For this press release, some people have criticized NASA trick, some even accused the media of irresponsible speculation

In order to search for black holes and dark matter observations, NASA in 1999 through the "Columbia" space shuttle to the Chandra X-ray space telescope into space. Chandra X-ray space telescope built by human beings is by far the most advanced and sophisticated space telescope, marks the era of X-ray astronomy into the spectrum from the metering time, can help astronomers better understand the origin and evolution of the universe .

As early as 5 days ago, NASA has said through its official website notice, the Chandra X-ray 15, Space Telescope will "recently discovered unusual objects in space," held a news conference. In the absence of more detailed information around the world into a variety of media speculation, and even some media speculation that NASA "may be announced the discovery of aliens or UFOs." Highly concerned about the large number of amateur astronomers news conference, the Chandra X-ray Space Telescope's official website was visited because of avalanche-like paralyzed. Although the 15 press conference announcing the news of astronomical research in the field called an event, but many people still feel the shock and the expectation gap is too large extent, criticism of NASA trick, is to increase the Chandra X-ray space Telescope and NASA's own degree of concern, many of accused some of the media in order to attract attention and irresponsible speculation.
